Comparing NFT Standards - ERC-721 vs ERC-721a vs ERC-1155

Wanna be in the same league as Damien Hirst, DC, and Niftys? Then build your NFT
on the Palm network! 

Infura and Palm NFT Studio [https://twitter.com/PalmNft] are excited to announce
that the Palm network is now available to all users of Infura. Nearly 430,000
developers now have access to create NFTs on the Palm network. 

The Palm NFT Studio

The Palm network is an Ethereum sidechain dedicated to selling, purchasing, and
trading NFTs that are associated with real-world and digital assets. Palm
provides low gas costs and fast transaction finality. The network is over 99%
more energy efficient than Proof of Work-based blockchain networks, providing
artists with a more sustainable solution today, while Ethereum upgrades to Proof
of Stake in the Merge, tentatively scheduled for release in July 2022.

The Palm NFT Studio has collaborated with Damien Hirst
[https://palm.io/studio/damien-hirst-currency-nft-updates/], DC
[https://palm.io/studio/creating-a-sustainable-future-for-digital-fandoms/], 
Niftys and Warner Brothers
[https://palm.io/studio/niftys-launches-the-matrix-resurrections-nft-project-on-the-palm-network/] 
and other artists in minting NFTs on the Palm network. 

How to mint an NFT on Palm

For users looking to mint NFT projects, the Palm network provides an effective
solution to create NFTs that are able to be bridged back to Ethereum.

To access the Palm mainnet or testnet endpoints, here’s how to get started:

1. Login [http://infura.io/login] to your Infura account and select an existing
Ethereum project (or create a new Ethereum project
[https://docs.infura.io/infura/create-a-project] if you have not yet). 

2. Click on the settings of the project to view the Palm API endpoints
[https://docs.infura.io/infura/networks/palm/getting-started/accessing-palm-api-endpoints]
.

Using Palm mainet and testnet is free as part of all Infura plans, and requests
sent to the API count as part of your existing plan. No action is required to
activate Palm, and the availability of Palm testnet allows you to have an
environment to begin developing and testing your NFT project before going live. 

See our documentation on Palm [https://docs.infura.io/infura/networks/palm] for

Ethereum Network Updates, Upgrades, Hard Forks

Infura - Ethereum Network Updates

Network

The Palm network is now available for all NFT creators on Infura

Last July, we published Ethereum JavaScript Libraries: web3.js vs. ethers.js
(Part I) [/ethereum-javascript-libraries-web3-js-vs-ethers-js-part-i/] to
provide “a comparison of web3.js and ethers.js, focusing on their similarities
and differences, so that you can better understand the nuances of the
libraries.”

To recap, we dove into the documentation of both libraries. We then used a
modified version of a software evaluation framework Andres Canal established in
his article “Using Quill,js to Build a WYSIWYG Editor for your Website
[https://www.scalablepath.com/blog/using-quill-js-build-wysiwyg-editor-website/]
” to guide the reader toward making the best decision in choosing which library
to use.

The article was “written with the intent of educating developers to understand
the tradeoffs between the two libraries to be able to make a decision of which
library to use for their particular use case.”

How have the conclusions from that article changed over the course of the past
year?

Table 1: Comparison of Conclusions about Web3.js and Ethers.js

July 2020October 2021Web3.js has a community of users and maintainers associated
with the Ethereum Foundation. Web3.js has a good API reference and has been
around since 2015. Many projects are using it and the library has been the go-to
in many "Build Your First dApp" tutorials.Web3.js is best for those who prefer
the most-used Ethereum javascript library that is also maintained by a
blockchain-focused firm. Web3.js's strengths are its tests and community.
Documentation is currently modest in design and scope and can definitely be
improved.Ethers.js is excellent because it is a small, compact library with a
large number of test cases. It has good “Getting Started” documentation, making
it accessible to new users. Developers find ethers.js simple and intuitive and
the library has gained in popularity over the past two years, seeing increased
downloads and usage by projects.Ethers.js is best for those who prefer
lightweight, user-friendly libraries with robust testing and documentation.
Ethers.js’s strengths are its documentation, tests and community. It could have
more maintainers in order to create some redundancy in the development team -
currently a single individual.

Let’s dive into the updated data and explain why these conclusions have changed.

1) How important is the popularity of the library?
To use Andres Canal’s definition,

“A popular project on Github means exactly what you expect it to. Namely, that
there are lots of people questioning, contributing, and supporting it. This
activity tends to result in more reliable software. You can check the popularity
of any project by looking at how many stars it has, how many issues are opened,
how many pull requests are pending, and how many contributors worked on the
project.”

Web3.js has about 11,600 stars
[https://github.com/ChainSafe/web3.js/pulse/monthly] and ethers.js 3,100
[https://github.com/ethers-io/ethers.js/pulse/monthly] as of Oct. 14, 2021. 
Web3.js is used by 112,849 repositories
[https://github.com/ChainSafe/web3.js/network/dependents?package_id=UGFja2FnZS0xNTA1NzY4MA%3D%3D]
, compared with 65,519 for ethers.js
[https://github.com/ethers-io/ethers.js/network/dependents?package_id=UGFja2FnZS0xNjEzMjI4Ng%3D%3D]
.

Looking back to July 2020, Web3.js had nearly 8,800 stars while ethers.js had
nearly 1,500. Web3.js was used by 51,300 repositories on GitHub, compared with
18,500 for ethers.js. 

Web3.js remains the more popular library, but impressively for both libraries,
their dependencies have at least doubled over this time period. Web3.js remains
more popular, but the overall pie of dependent projects has grown from about
69,800 to 178,368. We will dive more into the dependencies in question 3.

2) How important is the maintenance of the library?
To quote ourselves from the last article,

“We want to use libraries that are updated frequently, so that bugs are squashed
and new features are added. Though it is not perfect, looking at a month (or
two) of commits, closed issues, active issues, and the number of maintainers
over that time period can give a sense of the strengths and weaknesses of an
open source project. This also reveals patterns of maintenance, giving some
insight to the user of a library when updates and bug fixes are generally
addressed, which can be used as a proxy metric for maintenance of the library.”

Using the same metrics from our last article, we see the following for both
libraries.

Table 2: GitHub Monthly Pulse for Sept. 14, 2021 to Oct. 14, 2021

LibraryCommits to Main BranchClosed IssuesActive IssuesMaintainersweb3.js2060107
10ethers.js217391
GitHub Pulse now reveals some additional useful information about the libraries,
which gives us even more context of why we are seeing what we are seeing.

For web3.js, we can see that a single individual is responsible for the majority
of the commits, though there are three individuals that have 10 or more commits.
This is something I see as a plus. This means there is redundancy built into the
development team, in case someone were to stop contributing to the project.
Web3.js has 121 commits to branches other than the main branch, as web3.js is
transitioning off of the 1.x version as outlined in this blogpost the roadmap
for web3.js
[https://medium.com/chainsafe-systems/the-future-of-web3-js-v3-0-0-release-ecc9feecb2de] 
(which we will reference again in the next section). This indicates a lot of
work is going into the future releases.

For ethers.js, Richard Moore continues to be the sole maintainer of the library,
but there are many more people contributing to the project by opening and
closing issues on the GitHub repository, indicating that there is a community of
individuals committed to the health of the library. By virtue of a single
maintainer, it is not surprising to see fewer overall commits.

3) Who is responsible for the development of the library and how many projects
use it?
ChainSafe [https://chainsafe.io/] is the lead maintainer of the web3.js library, 
having received a grant from the Ethereum Foundation to “continue the
maintenance and further development”
[https://medium.com/chainsafe-systems/chainsafe-receives-grant-from-ef-for-web3js-9e4376f5f36a] 
of web3.js in September 2020. ChainSafe’s outline of the future plans for
web3.js
[https://medium.com/chainsafe-systems/the-future-of-web3-js-v3-0-0-release-ecc9feecb2de]
reveals major changes coming, such as the deprecation of web3-bzz and web3-shh
packages in version 3.x and an eventual move to Typescript in version 4.x. These
are exciting additions, but the tradeoff is that ChainSafe will need time to
realize these while maintaining the existing library.

Ethers [https://ethers.org/] is the lead maintainer of the ethers.js library,
which is Richard Moore’s project, so we can think of Richard Moore = Ethers.
Ethers has been the lead maintainer of the project since the inception of it.
This can be a risk for some projects, but in this case, it has made ethers.js
very quick in adding features and capabilities. For example, ethers.js is fully
TypeScript-ready with “definition files and full TypeScript source” according
to
the documentation [https://docs.ethers.io/v5/#features]. 


Table 3: Dependent Repository and Package Counts, October 15, 2021

LibraryDependent RepositoriesDependent Packagesweb3.js113,0184,685ethers.js
66,9503,505

Web3.js, likely due to the longer existence of the project, has more
repositories and packages that are dependent upon it. When compared with metrics
from our last article, ethers.js is closing the gap with web3.js when it comes
to dependent packages.

4) How important is it that the library has tests?
Answer: Very important to any dApp developer worth their salt. Luckily for us,
both libraries have gotten even better since our last article.

Ethers.js has a test suite API documented for the current v5 release on their
GitHub repository [https://docs.ethers.io/v5/testing/]. The documentation of
the
testing is very impressive [https://docs.ethers.io/v5/testing/]. Check it out.

Web3.js has added test documentation
[https://github.com/ChainSafe/web3.js/blob/1.x/TESTING.md] since our last
article. This documentation, based on my personal inspection, appears robust and
clearly written.

I believe ethers.js has the lead, but web3.js has done a great job catching up
in terms of its tests and their documentation, and I feel both have great
coverage when it comes to tests. Tests are a strength for both libraries now.

5) How important is the number of downloads of the library?
As of Oct. 15, 2021, web3.js has 30,767,910 downloads
[https://npm-stat.com/charts.html?package=web3&from=2015-01-01&to=2021-10-15] 
and ethers.js has 24,284,490 downloads
[https://npm-stat.com/charts.html?package=ethers&from=2015-01-01&to=2021-10-15].
Compare that with May 20, 2020, when we first looked at this statistic, when
web3.js had 14,703,432
[https://npm-stat.com/charts.html?package=web3&from=2015-01-01&to=2020-05-20] 
downloads and ethers.js had 8,500,336
[https://npm-stat.com/charts.html?package=ethers&from=2015-01-01&to=2020-05-20]
downloads. The overall pie has grown, but the difference in downloads is
surprisingly close: a difference in total downloads of 6,484,420 on Oct. 15,
2021 compared with a difference of 6,203,096 in late May of 2020. 

When we look at weekly downloads, the two libraries are practically even: 
web3.js at 330,102 [https://www.npmjs.com/package/web3] and ethers.js at 339,318
[https://www.npmjs.com/package/ethers]. Weekly downloads of both libraries have
nearly doubled since we last checked this statistic (May 20, 2020, for those
following along): web3.js at 175,661 [https://www.npmjs.com/package/web3] and
ethers.js at 184,798 [https://www.npmjs.com/package/ethers].

6) How important is web performance?
Web performance is indirectly measured by comparing the size of the libraries,
as we are assuming smaller libraries take less time to load in the browser. 

Both libraries are small. Web3.js has decreased the size of the library to 7.28
MB [https://www.npmjs.com/package/web3] unpacked (unpacked refers to the size of
the library when published) from 10.6 MB when we last checked. Ethers.js touts
its very small size, which has increased to 322 kb uncompressed
[https://www.npmjs.com/package/ethers] from 284 kb uncompressed over the same
time period. It’s unclear what occupies 322 kb within ethers.js. NPM shows
ethers.js 10.2 MB unpacked, and I confirmed this when I downloaded to my
personal machine and calculated the size of the ethers.js package using the
Finder application on Macs. So we have to take ethers.js's word that it is small
in size, which is a big plus, though I do need to do further research to confirm
this claim is valid.

7) How important is the quality of the documentation?
Ethers.js is the clear winner when it comes to the quality of the documentation
of the library and it stands out for three key reasons.

 1. Ethers.js has an extensive “Getting Started Guide,” which helps a user
    orient themselves to both the library and the vocabulary of Ethereum.
 2. Ethers.js has useful call outs and additional information provided as part
    of the documentation, giving the end user visual cues, convenient links, and
    other helpful user experience features that make reading and using the
    documentation an enjoyable experience.
 3. Ethers.js documentation has an extremely useful feature - a toggle to single
    page view, in which all documentation is provided on a single page. This
    makes using “Ctrl + f” in the documentation a breeze, and helps with finding
    the method you are looking for quickly.

Web3.js has not had many visible changes to the documentation since our last
article and could use an update to make the user experience more pleasant.

An indirect additional comment on the documentation - ethers.org provides a very
helpful “playground,” where you can try out the library in browser: 
https://playground.ethers.org/. This useful feature lets a user get started
playing around with the library quickly and easily. While it could be argued
that remix.ethereum.org provides a similar playground experience for web3.js,
this is not the goal of remix, and remix support ethers.js as well.

8) How important is the overall usage of the library?
The last time we looked at the numbers, web3.js was the clear winner in overall
usage, with ethers.js gaining users at a rate that appeared that it would only
be time before ethers.js caught up to web3.js. The results today show that both
have healthy ecosystems and a large number of users. My personal belief is that
the overall growth of the ecosystem shows that both libraries have been adopted
by a significant number of projects and users. So, while web3.js has more
downloads, stars, and overall metrics, ethers.js is competitive to web3.js in
its usage. It’s fair to say both have been widely adopted.

9) How important is the license?
This is one area that has not changed since we last reported. Web3.js still has
the LGPLv3 license and ethers.js the MIT license. I am not a lawyer, and so this
is the hardest area for me to pick a winner. It is worth reviewing Slava
Todavchich’s article “Understanding open-source and free software licensing
[https://medium.com/@moqod_development/understanding-open-source-and-free-software-licensing-c0fa600106c9]
,” which we suggested in our July 2020 blogpost.

But wait... there is a new category!

10) How important is the community and community experience?
Yes, I am adding a new way to evaluate the two libraries, based on my experience
in Developer Relations and Software Community. I am personally looking for
robust channels where developers using the software can interact with one
another, find information about updates and hotfixes, share their use cases and
help each other debug their code. The best software projects provide this for
their users and it is a differentiating factor.

Web3.js and ethers.js have both embraced Discord as a means to communicate
directly with their community of developers. Web3.js lives within the ChainSafe
Discord Server, in the channel #web3js-general. Web3.js has used this channel
not just to interact with developers, but  as of September 2021, to promote a
web3.js developer survey to help drive the direction of changes for version 4.x
of web3.js. Ethers.js utilizes the EF JavaScript Team Discord Server, in the
#ethers channel. Both are active channels with communication on a daily basis.

Both also use Twitter to communicate changes to their audiences, though both
have relatively light follower counts. @web3_js [https://twitter.com/web3_js] 
(1,250 followers) and @ethersproject [https://twitter.com/ethersproject] (1,279
followers) only tweet to announce updates and changes to the libraries, serving
as another way for notifications about updates to get through to developers.

ChainSafe also uses their Medium account to post some updates
[https://medium.com/chainsafe-systems] about web3.js, though not a regular
cadence.

GitHub continues to be a source of discussion for communities of both libraries,
though the shift to Discord by both reflects a growing trend in the Ethereum
community, as well as in software communities in general, to commit to this tool
for a mix of synchronous and asynchronous communication.

The verdict is that both take development and interaction with their communities
seriously.

What’s the next step? 

You should go ahead and test out the libraries themselves with Infura, and we
created a tutorial for just this purpose: Ethereum JavaScript Libraries:
web3.js
vs ethers.js (Part II)
[/ethereum-javascript-libraries-web3-js-vs-ethers-js-part-ii/]. The best way to
see if my evaluation is valid is to kick the tires on both libraries.

In conclusion, instead of declaring a winner, it seems that Ethereum itself is
benefitting from having two leading JavaScript front-end libraries. More
libraries being built that can utilize the features of web3.js and ethers.js
will push them to be even better (like web3-react
[https://github.com/NoahZinsmeister/web3-react], for example). In updating this
article, I have been struck by the growth of downloads and dependencies of both
libraries, making me of the opinion that you can choose either and feel
comfortable with the decision. I hope this illuminated some ways you can
evaluate both to choose what works best for you.

Ethereum JavaScript Libraries: Web3.js vs Ethers.js: An Update

As the clock ticks down to the Merge, the Teku and Infura teams have continued
refining their collaboration. In case you missed it, these two teams have
created an eye-poppingly fast Ethereum 2.0 client sync experience
[https://consensys.net/blog/teku/teku-and-infura-team-up-to-make-the-fastest-ethereum-2-0-client-sync/]
. Since then, they have continued refining their integration and made some
important discoveries and improvements.

Attestations with Teku
One of those discoveries was that validators linked to a remote beacon node
could have significant performance issues: specifically, a lot of missed
attestations. Obviously, this is a pretty crucial issue. It turned out to be not
just a problem with a remote beacon node, but specifically a remote beacon node
behind load balancers, including Infura’s load balancers. 

If you’re interested in the blow-by-blow, check out the Github issue here
[https://github.com/ConsenSys/teku/issues/4090].

The solution the team came to was to implement an option to disable early
attestation publishing when the block is received: 

--validators-early-attestations-enabled[=<FALSE>]

Find the full Teku documentation on this issue here
[https://docs.teku.consensys.net/en/latest/Reference/CLI/CLI-Syntax/#validators-early-attestations-enabled]
.

This option allowed validators connecting to Infura beacon nodes to have
performance equivalent to validators connected to a local beacon node, which in
and of itself is impressive. It would appear that this is a fix not just for
nodes connecting through Infura, but for any context where Teku validators are
using load-balanced beacon nodes.

The second innovation the team has made surrounding attestations is batch 
attestations. This consists of sending all attestations produced for a given
slot to the beacon node in a single batch. In the context of Infura, this allows
running a lot more validators without hitting rate limits.

The future of history
Another feature that the team has been working on, which isn’t quite ready yet
for a full release, is an innovative way to store historical state without
having a hard drive the size of the Library of Alexandria. 

With increasing adoption of decentralized technology, there is more and more
demand, and even novel use cases, for historical chain data. The most
top-of-mind for many in the space is tax compliance. Institutions and even
individuals are increasingly in need of solutions for being able to query,
quickly and cheaply, historical chain data.

Like most great things in this space, the solution being developed uses Merkle
tries. Without getting too deep into the woods (pun intended), as it’s not
finished yet, the technique essentially takes the difference between slots and
stores the branch updates. The applicability for this is tremendous, so watch
this space for more updates.

Safety through Diversity
As we approach the reality of Ethereum 2.0, more and more voices are calling out
a topic of vital importance: client diversity. The Ethereum Proof of Work
consensus mechanism is, at this point, venerable and battle-tested, at least in
blockchain terms, and is resistant to 51% of attacks. As the network transitions
to Proof of Stake, the threat remains that a single Ethereum client will be
running on a majority of validator nodes. This opens the door not only for a
malicious attack, but also for single points of failure bringing down the entire
network. 

For more explanation, check out this very readable primer
[https://blog.ethereum.org/2020/08/21/validated-why-client-diversity-matters/] 
that should bring a lot of issues into focus. There are so many reasons to make
the move to a Proof-of-Stake consensus model, and the network is on track to do
so. It would be a stunning failure of vision and quite simply, wildly unsafe to
move Ethereum to a PoS network that has a majority of any Ethereum client. 

Even if we were to assume that all clients were going to act in the best
interests of the network as a whole, which in and of itself is a leap most
aren’t willing to take, the Ethereum network is a sprawling global entity with
external dependencies. No client should be able to be a single point of failure
for the entire network. 

As we build the Beacon Chain and validators up and out, client diversity must be
included as an essential consideration.

Teku + Infura to 2.0: How to Handle Attestations

SoK: Validating Bridges as a Scaling Solution for Blockchains

So, why would you need a hybrid infrastructure model alongside Infura? 

Let’s think about how your database is set up. You probably have your own
database, which is great. What happens if that database goes down? Would your
app continue to run seamlessly, delivering the experience you want your
customers to get? Or, would your database shutdown cause outages and crashes in
your app? 

If the dataset you’re hosting is a public dataset, you have a new paradigm for
making your infrastructure much more resilient and reliable by integrating
Infura into your overall strategy. Infura implements a reverse proxy pattern
internally and can be a highly reliable and performant node in your
infrastructure stack, allowing you the ability to have a portion (or all) of
your traffic routed to Infura. 

You can choose to keep your database as your primary database with Infura as a
backup, or vice versa. In this way, Infura will act as an always-on backup for
your database, providing a level of flexibility previously not available with a
single database running. 

You also have the opportunity to use Infura as a stats comparison tool to make
sure your performance is up to par. Alternatively, you may need to handle more
load (request traffic) than your infrastructure can currently handle. You can
route the overflow to an Infura project ID to handle spikes in traffic so your
service stays up and running. 

There are many opportunities for you to use Infura alongside your own in-house
node infrastructure to improve your user experience. Let’s dive a little deeper
on how we accomplish this.

What does it mean when Infura implements a reverse proxy pattern?
Let’s review what a normal proxy is first, and then we’ll flip it and reverse
it, a la Missy Elliott, to talk about the reverse proxy. A proxy server (or web
proxy or forward proxy) is a server located in front of a group of client
machines (computers). When those computers make requests, the proxy server
intercepts those requests and communicates with the target web servers on behalf
of those clients. Basically, a proxy is a fancy word for a request/response
middleman. 

If you’re a visual learner, here’s a diagram from Cloudflare that shows just
where that forward proxy sits:

What is a reverse proxy? 
A reverse proxy is a server that typically sits on the edge of your
infrastructure. It is responsible for receiving requests from web clients and
subsequently routing them to one or more backend web servers. 

Here’s another great diagram from Cloudflare to show how the reverse proxy fits
in to the whole flow:




One of the main reasons to use a reverse proxy server is load balancing,
ensuring the flow of traffic between clients and servers remains smooth. This is
one of the main advantages of using both your own node and Infura. In addition,
it allows you to cache content and provides web acceleration for improved
performance. Lastly, reverse proxies allow for more efficient, secure SSL
encryption and protection from DDoS attacks and related security issues. 

As we previously mentioned, Infura can be used as a reverse proxy to assist with
ensuring the flow of traffic for your clients and servers stays as smooth as
possible, making for a more enjoyable user experience.

Some examples of a reverse proxy in action
Let’s first look at how we can set up a very simple reverse proxy using Caddy. 

We will use our localhost and a backend HTTP service running on 127.0.0.1:9000
to make sure we’re getting our reverse proxy working correctly. 

First, download Caddy [https://caddyserver.com/]. Once that’s downloaded, check
out their Getting Started guide here
[https://caddyserver.com/docs/getting-started]. Or, follow along to learn how to
set up a simple reverse proxy! 


At this point, you may be running your own node, but since it takes too long to
sync one for this article, we can substitute with a simple NodeJS stub to check
that our reverse proxy is working correctly. I simply named mine main.js.


const http = require('http');

const hostname = '127.0.0.1';
const port = 9000;

const server = http.createServer((req, res) => {
   res.statusCode = 200;
   res.setHeader('Content-Type', 'text/plain');
   res.end('Reverse proxy success!\n');
});

server.listen(port, hostname, () => {
   console.log(`Server running at http://${hostname}:${port}/`);
});


This sets up a backend HTTP service running on 127.0.0.1:9000 mentioned earlier
and will display a “Reverse proxy success!” message if our proxy is working
correctly. To start this, run `node main.js` in a different terminal window and
leave that connection open! 

Next, we will want to create a Caddyfile
[https://caddyserver.com/docs/quick-starts/caddyfile] (literally create a new
text file in whatever directory you’re working in and name it Caddyfile). Once
you have that set up, we will set up our simple reverse proxy itself inside the
Caddyfile with just two lines: 

localhost 

reverse_proxy 127.0.0.1:9000


In this instance, reverse_proxy is where we want to get our information from
(the original site), and localhost is where we are redirecting to using our
reverse proxy. 

Now, from the same directory as your Caddyfile in a new terminal window from
your `node main.js`, run:

caddy run


This will start the caddy server and will allow your reverse proxy to work! Now,
you’ll notice when you run this that you don’t see the “Reverse proxy success!”
message popping up. 

That’s because this just started the server. You now need to make a request to “
https://localhost” and you’ll see the message. To do this, open another terminal
window (that makes three now, for those of us keeping track), and simply run:

curl https://localhost


Running this command will give you the “Reverse proxy success!” message we were
looking for, and now you know you’ve successfully set up a simple reverse proxy. 

Enter Infura!
Now that we’ve gotten a basic reverse proxy up and running, let’s try one using
an Infura endpoint. We will keep our overall setup of using a Caddyfile the
same, but we won’t need the backend HTTP service running in the background, as
that will be switched to an Infura endpoint. 

We’re going to change up how our Caddyfile looks:

localhost 

reverse_proxy https://rinkeby.infura.io {
   header_up Host {/v3/<YOUR_PROJECT_ID>}
}


You will notice that we’ve added in a “header_up Host” inside the reverse_proxy 
section. This allows us to include our Project ID to both the Rinkeby endpoint
and the localhost endpoint we are proxying to. 

To test this out, we will need to send a request, so I used web3_clientVersion 
as an example: 

curl https://localhost/v3/<YOUR_PROJECT_ID> \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"web3_clientVersion","params": [],"id":1}'


When we run this, we get the following output: 

{"jsonrpc":"2.0","id":1,"result":"Geth/v1.10.8-omnibus-aef5bfb3/linux-amd64/go1.16.7"}


Cool! But how do I know my reverse proxy is working? Well, if you switch out
`localhost` in our curl command to `rinkeby.infura.io`, you get the same output,
which shows that our reverse proxy is running properly.

How do you use Infura as a backup for your own node?
We’re going to set things up initially the same as we did in the previous
example but with two upstreams, one to our localhost and the other to the Infura
node. 

Next, we’re going to set up load balancing. Now, what’s load balancing? Load
balancing acts like a traffic cop sitting in front of your application servers,
routing client requests across all the servers that can fulfill those requests
quickly and efficiently. 

So how do we set that up?

Since we’re using Caddy, we can refer to their docs
[https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#load-balancing] 
for the basics of how to use more than one upstream. When we look at lb_policy,
there are many ways to determine which upstream Caddy will use first. Caddy will
default to using the first listed upstream and will move down the list if the
servers stop responding. In our example, we want to have localhost:9000 from our
main.js file be the first upstream, meaning we want our reverse proxy to send
the data through our localhost first, so we will identify that by putting it
first in our list of upstreams (we will leave our Infura Rinkeby endpoint in as
the second upstream): 

localhost

reverse_proxy localhost:9000 https://rinkeby.infura.io {
   header_up Host {/v3/66172ed429624788ac264604755ba42c}
}


Since we are using the localhost:9000 port, we want to get that server back up
and running. In another terminal window, start the Node server with node main.js
.

To make sure everything is set up correctly, let’s run our request through by
running the same request from earlier but with the :9000 port included,
expecting to get the “Reverse proxy success!” message:

curl http://localhost:3000/v3/<YOUR_PROJECT_ID> \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"web3_clientVersion","params": [],"id":1}'


and we get the following output: 

Reverse proxy success!


Excellent! Now, how do we incorporate the Infura endpoint to be a fallback? 

You’ll notice we left the Infura endpoint in our Caddyfile where it originally
stood and we asked our proxy to load balance using the first upstream (our
localhost), which was how we got that “Reverse proxy success!” message. 

Now that we confirmed that we set everything up correctly on our end, we’re
going to kill the localhost server, mimicking what would happen if your private
node went down. Once we do that, our requests should automatically start routing
to the Infura node and we should get something similar to the below output:

{"jsonrpc":"2.0","id":1,"result":"Geth/v1.10.8-omnibus-aef5bfb3/linux-amd64/go1.16.7"}* Closing connection 0


But wait! We don’t get that! Instead, we get an error message. 

This is because Caddy only allows us to use either two HTTP or two HTTPS
endpoints - in our case, localhost is HTTP and our Infura endpoint is HTTPS. 

Luckily, there is a tool we can use to make this work with localhost that will
create a TLS certificate and sign it with a CA trusted locally by your device
and browser. That tool is called mkcert [https://github.com/FiloSottile/mkcert],
and it’s incredibly easy to install by following these steps
[https://web.dev/how-to-use-local-https/]. 

Keep in mind if you’re doing this with your own private HTTPS node, you likely 
will not need this additional step. 

If you are following our tutorial step-by-step (using localhost), be sure to
follow all the steps, including updating your main.js file to the below to
include the HTTPS requirement and the options constant. 

const https = require('https');
const fs = require('fs')
const options = {
   key: fs.readFileSync('<PATH_TO_CERTIFICATE-KEY_FILE>.pem'),
   cert: fs.readFileSync('<PATH_TO_CERTIFICATE_FILE>.pem')
};

const hostname = '127.0.0.1';
const port = 9000;

const server = https.createServer(options, function(req, res) {
   res.statusCode = 200;
   res.setHeader('Content-Type', 'text/plain');
   setTimeout(() => {res.end('Reverse proxy success!\n');}, 1000)
});

server.listen(port, hostname, () => {
   console.log(`Server running at https://${hostname}:${port}/`);
});


When you run the mkcert localhost command from the tutorial, the certificate key
file and certificate file used in the code above will be created.

Now that we have our localhost running with HTTPS, we can continue! Since we are
running everything with HTTPS, we need to update our Caddyfile to reflect those
changes.

localhost:3000 

reverse_proxy https://localhost:9000 https://rinkeby.infura.io {
   header_up Host {/v3/66172ed429624788ac264604755ba42c}
}


Now that we have all our files in order, let’s make sure our Node.js server is
running and send that request again. 

curl http://localhost:3000/v3/<YOUR_PROJECT_ID> \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"web3_clientVersion","params": [],"id":1}'


What do we get?

Reverse proxy success!


Perfect! That’s exactly what we want to get, as we have asked our reverse proxy
to go to https://localhost:9000 first. 

Now, what happens if we kill the Node server and send our request again?
Remember last time we did this, we got an error message. This time we should be
getting the result from our Infura Rinkeby node:

{"jsonrpc":"2.0","id":1,"result":"Geth/v1.10.8-omnibus-aef5bfb3/linux-amd64/go1.16.7"}


Success! 

Our reverse proxy is, in essence, ignoring the localhost node, as it’s not
functioning, and is defaulting to the Infura Rinkeby node! 

Super easy, right? Now you know how to use Infura as a backup node to keep your
services up and running smoothly!

Where can I learn more about reverse proxies?
Take a look at our client story from MakerDAO
[https://infura.io/customers/maker]. They currently use Infura for a multitude
of reasons, including using us as a backup node solution to ensure all
developers can use the MakerDAO toolkit! 

Another great example is the Polygon PoS network
[https://docs.infura.io/infura/networks/polygon-pos]. We initially began working
with Polygon to share some traffic load for their network, allowing users to
access the Polygon networks via Infura endpoints and effectively ensuring their
network remains fast and functional, regardless of traffic spikes they may see.
We have since increased our partnership so we are now handling 100% of their
network traffic.

How to Run Your Own Node AND an Infura Node

When enterprise developers build dapps on Ethereum, they often have to consider
the entire tech stack and development process. The list of considerations range
from application features such as Web2 interfaces to deployment, which is
usually on a permissioned network hosted by a preferred cloud provider. Since
most full-stack software engineers build off of SDKs and API calls, it’s
important to establish the value of the application with consideration of the
deployment network.


Get the best of both Web2 and Web3 worlds
Many enterprise blockchain business cases build on the principles of traditional
Web2 development. Web2 focuses on operating with a fluid user experience with
attention to detail on scalable and responsive code on multiple devices. A
valuable decentralized application (dapp) in Web3 redesigns the economics and
industry roles while building on complementary existing systems -- instead of
fully replacing those systems with analogous Web3 features. 

Say you would like to reinvent a syndicated loans issuance platform such as
IPREO. This effort would require significant IT resources to spin up a minimum
viable product from the ground up if you’re recreating features like tranche
issuance calculations or calendar date exceptions. Instead, consider a path to
lesser resistance: blockchain modules that connect these digital assets to new
liquidity networks. The functionality is a re-issuance of an existing financial
instrument to ABC network with a listing on XYZ automatic market maker rather
than the full end-to-end dashboard.

To connect to pockets of liquidity, an enterprise developer must deploy with the
same smart contract language that is compatible with the Ethereum Virtual
Machine (EVM) and look to bridge the assets to networks with the desired
investor and issuer markets.

Why build on public Ethereum?
Until now, publishing enterprise dapps on Ethereum requires significant system
integration, executive buy-in and high set-up costs. Recently, we have seen more
public blockchains working with enterprises to cover non-functional technical
needs in order to meet minimum requirements of security audits and performance.
However, the relatively tribal nature of the blockchain developer subculture
means that mainstream enterprises are still conservative when it comes to
building on Ethereum.

If you are an enterprise developer, consider the following advantages of
building on public Ethereum vs. permissioned networks:

1. Faster setup and lower total cost of ownership

2. Immutability and longevity of the data stored with thousands of independent
nodes

3. Composability and low barrier of entry to decentralized finance (DeFi)



1. Faster set-up and lower total cost of ownership
This is a standard private blockchain journey for a consortium:

After you develop your dapp, a lot of time is focused on node deployment
adhering to enterprise software standards. On the business side, you are also
trying to build a consortium to agree on the benefits and adoption before the
tech is tested. 

The consortium model usually chooses a separate tech vendor that does not have
single ownership from one consortium member to prevent conflicts of interest.
The tech vendor determining deployment and long-term support likely runs the
Ethereum nodes on behalf of participants. This will get the product to market
faster and focus on the business benefits. 

The last step involves time and licenses for adding more nodes and mutualizing
infrastructure costs across participants. Compared with private networks that
remove tokens from their operation, public networks require ownership of native
tokens to fund transactions. This gas cost pays for the infrastructure -- third
parties running full nodes and running operations for mining/validating. In my
time building enterprise projects, we have never seen this happen.

The public journey is much more straightforward. After you develop your dapp,
the deployment is a choice between public networks with updated configurations
on your Truffle setup. The added complexity is the gas costs for funding and
running your transactions on this network. 

To simplify connectivity to EVM-compatible networks, you can use Infura’s 
Ethereum API [https://infura.io/product/ethereum] to connect your app instantly
with a single line of code. Simplify your transaction management with Infura
Transactions (ITX)
[/why-you-should-use-infura-transactions-instead-of-building-your-own-in-house-relayer/] 
using prepaid accounts without holding ETH on your balance sheets. ITX is a
transaction relayer that manages your transactions to prevent dropped or stuck
transactions.

You will also likely want to work with a team such as Diligence that can audit
your contracts and monitor them when they’re live.

Public Ethereum has an overall lower total cost of ownership when you compare
the operational cost of running a system on mainnet rather than focusing on the
ownership and maintenance of the network itself. 

A consortium may have more control in the private chain and face less security
and treasury reviews at first. However, your infrastructure overhead and
negotiations on consortium network matters tend to outweigh the convenience and
added features of connecting to mainnet.

2. Immutability and Longevity
The Ethereum mainnet is secured by the interaction of thousands of independent
nodes run by individuals and miners throughout the world. Private chains
typically have a small number of nodes controlled by one or a few organizations.
Those nodes can be tightly controlled, but only a few need to be compromised in
order to rewrite the chain or commit fraudulent transactions.

At ConsenSys, we’ve recommended public networks to enterprise developers for
their resilience of replicated data as you are able to recover more quickly with
a larger network of more than 15,000 independent nodes. The more peers you have,
the easier it is to find a seed and fully recover your recorded transactions. In
consensus decisions, the more blockchain validators there are to verify
transactions, the more difficult it is to coordinate a majority decision that
may lead to an attack. 

In a permissioned network, the security is governed by the node with the least
security. Your network is only as secure as the weakest link. Any added nodes to
the network may also increase the surface area of attack. Most institutions will
recommend a base software security test in order to join as a full node owner.
The node owner will have to pass standard penetration testing to prevent any
hacking on the node in case it is a bad actor to the entire network.

3. Composability and Low Barrier to Entry on DeFi

The Ethereum network powers a vibrant ecosystem of third party applications and
technology including DeFi and NFTs. A highly composable and interoperable system
allows you to connect to DeFi to build financial products that enable and
combine multiple apps to match specific user needs. The Ethereum mainnet offers
enterprise developers the ability to gain access to market liquidity and provide
innovative ways for users to participate in the exchange, trading or growth of
that liquidity. 

When we say composable, it’s much more than just an open banking API. It’s a set
of open source live protocol contracts that can be called and extended. We’ve
seen pure forks of open source code like with Uniswap to get sushiswap. The
market has seen countless copies of DeFi models such as Compound and Aave, and
it doesn’t look like things are slowing down anytime soon. 

There’s more and more real value happening in DeFi leading us to believe that
cryptocurrencies are not a fad. It is here to stay.

3 things enterprise developers should consider when deploying on Ethereum

Are you excited by blockchain but don’t have a great deal of experience coding?
It can be easy to fall down a rabbit hole of technical tutorials that make
assumptions regarding your initial development knowledge. A particularly
important topic to grasp is basic security within your code. 

As you begin to build out your very own dApp, you will have to include
information such as an Infura API key, along with a mnemonic. 

If you are new to coding, this is the equivalent of giving a stranger your
social security number and keys to your home. Once this information is public,
there is no definitive way to ensure it hasn’t been captured by a person or web
crawler, which could result in malicious behavior. 

So, how can we address this? 

Thankfully, we can use dotenv along with git to protect our sensitive
information within our project when / if we push to github.

Dotenv is a zero-dependency module that loads environment variables from a .env
file into process.env, storing configuration in the environment separate from
the code. It is often a convention for environment variables to be stored in a
.env file or other mechanisms based on the server you are using. 

Note: This article will focus on building out a project using Truffle
[https://www.trufflesuite.com/] and Infura.

In our project, we will need to run the following command:

npm i dotenv

Once the process in our terminal has been completed, we will want to make sure
we have the dependency successfully installed. Head over to your package.json
file and check to ensure that dotenv has been added under dependencies.

Next, at the root of our project, let’s create a .env file: 

Here is where you will add all of the sensitive information that should not be
shared. 

We will make sure we can access our .env information in our truffle.config file.
At the top of the truffle.config file, add the following: 

require("dotenv").config

This will tell your project to load anything that is in the .env into an
environment variable, granting you access to it. 

Now, instead of having to put our Infura api key or mnemonic in an exposed file,
we can import that information from our .env file. 

When it comes to gaining access to our project key we are going to use, sign up
to Infura [https://infura.io/register] and create a project. In your dashboard,
you should see something similar to this: 

The following code is an example between the usage of .env and exposed
information within truffle.config: 

const HDWalletProvider = require('@truffle/hdwallet-provider');
const infuraURL = 'https://rinkeby.infura.io/v3/<project id here>'
const mnemonic = "Your mnemonic here"

rinkeby: {
provider: () => new HDWalletProvider (mnemonic, infuraURL),
network_id: 4,
gas: 5500000,
confirmations: 2,
timeoutBlocks: 200,
skipDryRun: true
},

Imagine if you pushed this up to github. Anyone would have the ability to open
your truffle.config file could take advantage of your exposed mnemonic and
project id from Infura. 

Let’s take a look at that same code and implement better security practices. 

Notice how we are calling upon the information without having to directly add to
our file.

One important detail, as of now even with an .env file: if you push this project
to github, it will show the .env file, which would defeat the purpose! 

Take a look for yourself.

This is where .gitignore comes into play. We will need to create a .gitignore
file, so we can push this project up to github.

Without getting into git, a quick summary could be git is version control
software that keeps track of all of your files and the versions of them. What
.gitignore does is it tells git not to keep track of this file along with
everything it contains. 

If you want to dive deeper into git along with other foundational material, have
a look at our Basic Training
[https://courses.consensys.net/courses/bootcamp-basic-training], a free course
that helps ensure you have the fundamental tools when developing. 

At our root (similar to the level our .env file lives), we will create a
.gitignore. Inside of that file, we will add .env along with any other files you
would rather not be pushed to github. 

We can now push our project up to github and notice that our .env file is no
longer exposed. Our sensitive information is now much more secure. 

If you are experimenting with this, make sure you add your .env file to your
.gitignore before pushing. 

If you are running into issues, remember gitignore ignores only untracked files.
If your files were committed in the past, they are now tracked by git. To ignore
them, you first need to delete said files, git rm them, commit and then ignore.

Otherwise, you can delete the .env file and run 

Git rm .env --cached

Here
[https://docs.github.com/en/github/authenticating-to-github/keeping-your-account-and-data-secure/removing-sensitive-data-from-a-repository] 
is a helpful link discussing the removal of sensitive data from a repo if it was
previously committed and discusses how to clean the git history. Savvy attackers
don't just look at the most recent repository info, they'll look at the history
of it as well.

Note: If you come across it in documentation, a question you might have is
“What is env. example”

An env. example file, on the contrary to this tutorial, is actually included in
the repository, it is used as an example file for you to know what KEY=VALUE
pairs you need for your project. Most often, it is used to copy the .env file
and then change the values. 

Example of execution: 
Enter to the project root directory using your terminal.

Check if .env the file exists or not.

If the file does not exist then create a file named .env.

Now execute the command

cp .env.local .env.

So the .env.sample file has all the ENV declarations defined but without their
values. It helps other developers establish/set up the project without having to
reverse-engineer the codebase.

So after git clone, you usually execute the command `cp .env.sample .env` and
fill in the values with the Infura credentials as we saw in the example above. 

Note: When you create a new repo using github, if you scroll down you should see
the option to include a .gitignore file so you don’t have to create one yourself
in the future.

How to Use .env to Enhance Basic Security Within Your DApp

Optimistic Ethereum is a rollup scaling solution that allows users to submit
transactions on the Ethereum network and get them executed faster for a much
lower gas cost. From the perspectives of users and developers, this is a
"parallel universe" called Layer 2, or L2, where users typically have the same
addresses as they do on the Ethereum blockchain (also called Layer 1 or L1).
There are gateways that allow messages and assets to be transferred between the
universes.

The Optimism network API largely uses the same JSON-RPC specification as
Ethereum and Infura supports all the necessary API methods for building a fully
functional application on the Optimistic Ethereum network.

Why are transactions cheaper on Optimism?
On L1 Ethereum, thousands of nodes run your transaction to verify that the
proposed block that includes it is valid. This process is expensive and has to
be paid for. Unlike on L1 Ethereum, Optimistic roll ups provide faster and
cheaper transactions because it allows users to perform most of their tasks
off-chain in a "layer 2" protocol. On Optimistic Ethereum, the smart contract
has only two tasks: deposits/withdrawals and verifying proofs of transactions on
chain. This makes the process more efficient and a lot cheaper.

Why is this safe?
The great thing about decentralization is you can trust that transactions are
executed correctly because there are thousands of computers executing them.
Honest miners would reject such a transaction. With rollups, you don't have that
level of redundancy.

The answer, in the case of optimistic rollups, is incentives. Every node in the
network has to put up a stake before it can propose a new block with the
execution results of a transaction. Every other node can check up on those
results, and if it thinks they are incorrect, dispute them. The dispute is
resolved on L1, so it is as trustworthy as anything else in Ethereum. Whichever
node lies, either proposer or disputer, loses its stake and most of it goes to
the other node involved.

Of course, the whole point is to avoid running transactions in L1. This system
achieves that by making it pointless to cheat. Any proposer who attempts to
cheat is going to be caught by the other nodes, lose its stake, and not get the
invalid transaction result accepted as valid. A disputer can force a single
transaction to go into L1 arbitration as a denial of service attack, but the
stake is high enough that it wouldn't be worth doing.

How does Infura work with Optimism?
Infura exposes endpoints for Optimistic Ethereum (the production network) and
Optimistic Kovan (the test network). You use them the same way you use any other
network, by selecting them from the menu and using the specified endpoint.

There are a few small differences between building on Layer 1 Ethereum and
Optimism:

1. You must use the JSON-RPC API as we do not support Websockets yet.
2. Search filters are not yet supported

How to Get Started on Optimism...


The main difference between Optimism and regular L1 Ethereum (other than the
cost) is the access point URL. 

| Network          | RPC URL |

… If you are using the Truffle development environment
Infura users can add the free Truffle Optimism add-on directly on their Infura
dashboard. The Truffle Optimism box also contains the configuration definitions
[https://trufflesuite.com/boxes/optimism] required to use Infura. Currently, you
will need to manually add the gas costs of transactions when you use Truffle to
run deployments or tests on Optimistic Kovan or the main Optimistic Ethereum
network.

… If you are using Hardhat
To use Optimistic Ethereum or Kovan, edit hardhat.config.js's 
modules.export.networks
[https://github.com/ethereum-optimism/optimism-tutorial/pull/60/files] to add
these definitions:

> "optimistic-kovan": {
url: 'https://optimism-kovan.infura.io/v3/<Infura Project ID>',
accounts: { mnemonic: <your account mnemonic goes here> },
gasPrice: 15000000,
ovm: true // This sets the network as using the ovm and ensure
// contract will be compiled against that.
},
"optimistic-ethereum": {
url: 'https://optimism-mainnet.infura.io/v3/<Infura Project ID>',
accounts: { mnemonic: <your account mnemonic goes here> },
gasPrice: 15000000,
ovm: true // This sets the network as using the ovm and ensure
// contract will be compiled against that.
}


Then you simply run:

> npx hardhat --network optimistic-<kovan or ethereum> <command>

… If you are using Remix
When you use the Remix Optimism plugin
[https://remix-optimism-compiler-plugin.readthedocs.io/en/latest?xgtab&] to
develop for Optimism, network connections are created through the wallet. If you
use MetaMask, you can select the network Custom RPC and fill in the details:

What is Optimistic Ethereum?

Today we are very pleased to announce the private beta launch of a new and
improved IPFS [https://infura.io/product/ipfs]. Over the last four years, Infura
has provided developers with a simplified access path to Ethereum and IPFS. In
setting up the first public IPFS APIs and Gateway alongside our Ethereum API, we
built a foundational Web3 development service for building decentralized
applications. Despite facilitating access to IPFS, we have come to think of this
as an alpha release.


Our new enhanced IPFS service expands on the current API functionality by
offering a full Infura dashboard, more features to help you optimize usage, and
dynamic scaling for developers with production ready applications. We also
introduce authentication for API usage and metered billing, where you only pay
for what you use above the free storage and bandwidth (5 GB storage, 5 GB upload
and 5GB download).

With the interest in digital collectibles and art being at an all time high, we
are excited to help this community grow and thrive. For more information on the
updates to the IPFS service, and how to sign up, please click here

[/how-barter-built-a-direct-nft-trading-interface-for-real-time-negotiation/?&utm_source=infurablog&utm_medium=newsletter&utm_campaign=monthly_update&utm_content=mar21_update]
Barter, a project built by ConsenSys Academy student Robert Clark, is
specifically engineered for a future where video game assets are tradeable and
where the Metaverse begins to emerge as a social phenomenon. With Barter, a
direct trading interface between two people allows for real-time negotiation as
well as new item discovery. We walk you through how this developer built Barter
from the ground up, using Infura and Truffle.

The Financialization of NFTs
[https://consensys.net/blog/codefi/roi-opportunities-for-nfts/?utm_campaign=ConsenSys%20Newsletter&utm_medium=email&_hsmi=115699190&_hsenc=p2ANqtz-9SW8TqEHOCrT8o5zVyYjzIAVHB-GuPxoT6Egfm7xKfWJhozUTOiPKwdEOCTrDFUuFH4usmGlbRP6LsHSJW2h52y4Z-IA&utm_content=115696829&utm_source=infura]
Many projects are looking to bring liquidity to NFTs, allowing the holders to
earn yield. We examine three of the leading projects looking to financialize
NFTs: NFTX, Charged Particles, and Aavegotchi. NFTX allows users to create funds
of NFTs that they can then trade on decentralized exchanges like Uniswap, while
Charged Particles allows users to add interest bearing tokens to their NFTs.
Finally, Aavegotchi introduces some interesting game theory to interest bearing
NFTs so that the user must decide between the interest and the NFT itself.

Introducing Palm NFT Studio

Claim Infura Bounties at the Chainlink Spring 2021 Hackathon Happening Now!
Chainlink Hackathon 2021 [http://chain.link/hackathon] is in full swing, and we
are thrilled to sponsor this years event. The hackathon runs from March 15 -
April 11, so you still have time to jump in and hack on some bounties from
Infura and Codefi [https://chainlink-2021.devpost.com/]! Our very own EG from
Infura will be judging the bounties as well. So jump in and let’s build!
[https://discord.gg/34vnttMmBk]

Infura Bounty: We have recently released Infura Transaction Service (ITX)
[https://infura.io/docs/transactions?&utm_source=infurablog&utm_medium=newsletter&utm_campaign=monthly_update&utm_content=mar21_update]
. It is a high-throughput relayer that is optimized to reliably send
transactions to the Ethereum mainnet in a timely manner while ensuring all
transactions do not needlessly overpay the network fee. It is a simple API that
is easy to plug-and-play for most projects. Our bounty focuses on integrating
ITX with the Chainlink Oracle system (node). The final solution should allow
node operators to activate ITX via a config file (or an additional parameter) at
the command line. Once it is turned on, all transactions for the oracle will be
sent via the ITX service. We hope this integration will help Chainlink fall from
the Top 25 Leaderboard [https://ethgasstation.info/] for services that pay the
most Ethereum network fees and thus reduce the cost of being a Chainlink
operator. $1,500 goes to the Infura Project Winner!

Infura | March 2021 Update

Reflecting on Infura’s four year journey to expand access to Ethereum
This past July, we celebrated two birthdays: Ethereum turned five and Infura
turned four. In the wake of these milestones, I want to take some time to
reflect on why Infura came to be, how our service has evolved over the last four
years, and talk about what excites us as we look towards the future.

Block0: bootstrapping Ethereum
Ethereum was created to be an open source programmable network, built by
developers for developers. Like any open source platform, it offered builders
the opportunity to create and maintain all the infrastructure components that
keep the network up and running. Ethereum quickly became the number one, smart
contract based blockchain and its growth would be critical to the expansion of
the broader blockchain market. That saddled Ethereum developers with an enormous
responsibility. 

There was a need for utilities that provided simplified access to Ethereum data
and lowered the barrier to entry for developers to get more people building on
the network. 

We publicly launched Infura in 2016 at Devcon2 in Shanghai. Funded by Joseph
Lubin and ConsenSys, our mission was to take up the Ethereum infrastructure
challenge: to remove the burden of running and maintaining Ethereum nodes by
providing free, public APIs. We also perceived the potential for future
integration between Ethereum and the InterPlanetary File System (IPFS) and set
about providing a simplified access path to IPFS alongside.

Supporting the largest dApps in the Ethereum Ecosystem
Traffic through the Infura APIs has consistently increased quarter over quarter,
year over year for the last four years, thanks to strong developer adoption. Our
earliest adopters were the MetaMask [https://metamask.io/] development team, who
have used Infura to scale their application from zero to +1.2 million installs,
making it the world’s most popular Ethereum wallet.

During the crypto collectibles craze of 2017, we also played a key role in
scaling one of the most viral dApps in Ethereum’s history. As the network
swelled with users wanting to create and trade digital kittens, the
Cryptokitties app went viral and grew so fast, it clogged up the Ethereum
network
[https://media.consensys.net/the-inside-story-of-the-cryptokitties-congestion-crisis-499b35d119cc]
. This arguably led to one of the biggest spikes in the value of Ethereum and
catapulted Ethereum into the public scene. Infura joined other Ethereum OG
development teams to help Cryptokitties optimize their infrastructure to handle
the unprecedented wave in traffic and maintain uptime, at no cost. 


These early episodes truly battle-tested our product and pushed our engineering
team. As a result, Infura engineers have earned a reputation for building the
most reliable tools in the industry. Today, our service supports a rich and
varied universe of decentralized projects and some of the largest consumer apps
in the ecosystem. 

A more recent example is Uniswap
[https://infura.io/customers/uniswap?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime]
, and their rapid rise to DeFi dominance. We’ve been supporting Uniswap as their
infrastructure partner since they first deployed to mainnet, back in 2018. By
offering simplified integration and the ability to confidently handle high
request volumes, Infura has helped Uniswap in becoming one of the most active
protocols in DeFi and service unprecedented consumer demand in record time;
scaling their platform from +$285K in Total Locked Transaction Value in August
2020, to  over 1.8B USD at its peak in September.


The Uniswap team is working incredibly hard to add more liquidity to the DeFi
ecosystem - and more liquidity means more users and integrations. Our goal has
always been to empower developers building meaningful apps utilizing the power
of Ethereum and IPFS and Uniswap is a perfect example of that coming to
fruition.

> "Infura is a great solution for us. It’s easy to integrate, can handle our
requests, and has really helpful and thorough documentation. If we were to run
and manage our own infrastructure, we would need at least one full time engineer
to monitor that on a consistent basis. Infura helps us improve the reliability
and performance of our service and saves us developer time and resources so we
can focus instead on accelerating core product development."

> Ian Lapham, Software Engineer, Uniswap.
Creating New Markets
After three years of providing Ethereum and IPFS infrastructure, we observed the
number of developers with high volume, production-grade applications growing and
growing. We knew it was time to formally release our flagship Ethereum product,
to give developers confidence that Infura was going to grow with them. In July
2019, we launched Infura+, our premium Ethereum API product
[https://infura.io/pricing?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime]
. This introduced clear scaling access to our Ethereum infrastructure and
advanced support solutions. Maintaining free access to the API was extremely
important to us because we knew that Ethereum and IPFS were both still in their
experimentation phases. The importance of keeping access easy and free remains
critical to enabling the continued growth of these technologies. We have a ton
of new features on the horizon, both free and paid, and we are thrilled to talk
more about those later this year! 

While we started Infura to connect more developers to Ethereum, we’ve ended up
creating an entirely new sub-industry: Blockchain Infrastructure-As-A-Service.
Our viability and continued growth has enabled other development teams to enter
the Web3 market and spin up their own Infrastructure service to help scale
Ethereum and other chains. In 2016, there was only Infura. Today, there are
dozens of blockchain infrastructure service providers, making this emerging
market strong and diverse.

Helping the Ethereum Community Build Better Architecture

We strive to give back to developers as much as we can to help foster better,
more varied applications on Ethereum and IPFS. Our engineers regularly take
components critical to our infrastructure and share them with the wider
community to help enable better tools and infrastructure. This includes
up-streaming into the Go-Ethereum and Go-IPFS clients, while also maintaining
fully open source tooling for both Ethereum and IPFS infrastructure.

Our Open Architecture Initiative
[/building-better-ethereum-infrastructure-48e76c94724b/?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
is an effort to consolidate the knowledge and experience we’ve accumulated over
the years and provide visibility into Infura’s architecture.

You can find some of our open-sourced tools here
[https://github.com/INFURA?q=&type=public&language=]. They range from IPFS
monitoring plugins to analyzers of the Ethereum P2P layer. You can directly test
our service against local nodes and other providers using our comparison tool
called Versus
[/compare-ethereum-api-performance-with-versus/?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime]
. In July this year, we released eth2-comply
[https://github.com/INFURA/eth2-comply]: an open source Apache 2.0-licensed tool
for testing client API conformance. This tool supports Ethereum 2.0 client teams
working towards compatibility with the Ethereum 2.0 API specification
[https://ethereum.github.io/eth2.0-APIs/].

Empowering Builders to Reinvent Old Systems
Developers are smart, creative and energized by problems. It’s incredibly
heartening to see how devs are using Ethereum to reimagine different industries,
and scaling those projects with Infura; from the future of work
[https://infura.io/customers/colony?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
to marketing analytics
[https://infura.io/customers/lucidity?utm_source=blog&utm_medium=referral&utm_campaign=4%20Years%20of%20Uptime?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime]
, developer tools
[https://infura.io/customers/openzeppelin?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
and gaming
[https://infura.io/customers/skyweaver?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime]
. 

Undeniably DeFi (Decentralized Finance) is having its moment right now, as dApps
and protocols proliferate across Ethereum. In addition to Uniswap, I want to
highlight a few other Infura users driving great adoption in the DeFi space:

 * Compound
   [https://infura.io/customers/compound?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
   provides interest rate markets on Ethereum, enabling any crypto user to
   deposit to the lending pool and accrue interest on that contribution.
   Compound enables anyone to save and earn against their savings.
   
 * Monerium
   [https://infura.io/customers/monerium?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
   aims to revolutionize the cost of doing business by using Ethereum to achieve
   instant invoice settlement at a fraction of the cost of traditional methods. 
   
 * Gnosis
   [https://infura.io/customers/gnosis?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
   has built interoperable market mechanisms and protocols that allow DeFi users
   to securely generate, exchange, and hold digital assets. The platform
   connects users to Ethereum through the Gnosis multisig wallet and displays
   token balances via the Gnosis mobile app.
   
 * MakerDAO
   [https://infura.io/customers/maker?&utm_source=infurablog&utm_medium=referral&utm_campaign=announcement&utm_content=four_years_of_uptime] 
   is one of the most well known projects on Ethereum, with one of the most
   widely adopted stable coins (DAI). A big part of Maker’s appeal is its
   collection of developer tools. We work very closely with the Maker team to
   help developers utilizing their components get up and running as fast as
   possible. The Maker team and Infura share the goal of giving developers the
   tools to use this powerful technology, check out their developer
   documentation [https://github.com/makerdao/developerguides].

Supporting the Creation of New Business Models
As we expand the Infura suite, we want to ensure that we remain true to our
mission: to provide developers with everything they need to build
next-generation software and support the creation of all new types of businesses
and applications. That’s one of the reasons we’re excited to support Eth2. 

Ethereum 2.0 (Eth2) is an approaching Ethereum network upgrade. Like all
upgrades, it’s designed to improve network performance—but the most interesting
aspect of Eth2 is its Proof of Stake (PoS) enhancement. 

If you’re not familiar with Eth2, this explainer should help. 

> Eth2 incentivizes ETH holders to become a validator and help maintain the
Ethereum network. By staking (depositing) 32 ETH, one can download and run Eth2
client software and be rewarded for correctly validating blocks. Think of it as
a mechanism for earning interest on your ETH, while incentivizing a faster, more
secure network.

Our Eth2 service launched in June 2020 supporting the Beacon Chain layer of the
network. This is a critical piece of the network that validators depend on to
maintain their view of the overall state of the network. We are eagerly awaiting
the mainnet launch of Eth2 and will be working closely with the ecosystem to
provide developers and validators with the tools they need to immediately start
using Eth2.

You can preview the product by becoming an Infura Beacon Chain API tester. Just 
drop us a message

Four Years of Uptime

Last week, Protocol Labs gave us the opportunity to participate in the first
ever IPFS Pinning Summit [https://ipfspinningsummit.com/] to share the past,
present, and future for IPFS as an essential component of Infura’s Web3
development suite. For those of you who are familiar with Infura, you will know
we have a long history of support for IPFS and we’d like to thank Protocol Labs
for the opportunity to share our progress. Here’s a quick recap of what we spoke
about. 

Infura
[http://infura.io/?&utm_source=infurablog&utm_medium=referral&utm_campaign=event_recap&utm_content=ipfs_pinning_summit] 
was formed in 2016 initially as a project to provide shared Ethereum node
infrastructure to support other projects within ConsenSys. By providing a
connection to the Ethereum network via an API endpoint, Infura freed up
developers from having to manage that infrastructure themselves. While at the
time, running an Ethereum node wasn't particularly difficult, scaling an
application meant more nodes, more disk space, full-time infrastructure
engineers, and ultimately more costs. We quickly realized that a service such as
Infura would make building and scaling applications on Ethereum easier, and
would be incredibly valuable for the ecosystem as a whole. 

Ethereum is great for computation, but what about storage?
As decentralized, Web3 development design patterns began to emerge, it was
quickly obvious that while Ethereum provided trustless computation, truly
decentralized applications would need a storage solution to complement it. The
S3 to EC2 if you will. Based on this, we decided to set up one of the first
public IPFS APIs and Gateway alongside our Ethereum API to build the foundation
of our Web3 development suite.

Over the last 4 years, we have worked with our community of developers to
explore exciting use-cases, debug common issues, and serve IPFS as a key part of
our Web3 strategy. We have worked with users storing documents, art assets,
music, videos, social network information, photos, and so much more. 

Our IPFS Service Today
We have primarily focused on making improvements to our underlying IPFS
architecture in order to support the amazing adoption of this service.  We
support pinning and accessing pinned content directly via the API and allow
users to access data pinned across the IPFS network via the Gateway. We have
supported over 40 million unique objects and are currently handling over 2 TB of
data transfer per day. 

We have also committed to providing contributions to the open source IPFS
community. You can learn more about two of our internal tools, ipfs-pump and
go-ipfs-datadog-plugin here [https://bit.ly/2YPSvln]. 

Check out our documentation
[https://infura.io/docs?&utm_source=infurablog&utm_medium=referral&utm_campaign=event_recap&utm_content=ipfs_pinning_summit] 
for a full list of our supported functionality.

What’s Next?
Looking forward, we are preparing for the launch of our premium IPFS product.
This new product will expand on the current API and Gateway functionality, full
dashboard and the latest auth integration, and an overall more reliable and
scalable solution for developers with production ready applications. We will
have much more on this in the coming months.

sign ups and DAI payouts were facilitated using a tournament platform that
allows anyone to organize tournaments from start to finish with easy participant
onboarding and smart contract-powered payments. The platform currently showcases
Ethereum-powered payments and prize pool management that is fast and
inexpensive.

Taking home the 500 DAI first place prize was 🥇MaxHS, a veteran SkyWeaver
player and former Hearthstone pro. He edged out 🥈TerrenceM, another well known
NYC local digital card game player, who walked away with 300 DAI.
🥉Cybourgeoisie and 🥉Feihu tied for 3rd and both took home 100 DAI.

engineering demands are required to battle-test these new systems as adoption
scales. Infura’s ability to reliably manage scale ultimately led Horizon to
choose Infura as their Infrastructure partner for SkyWeaver.

> “The Infura team had proven their ability to handle this scale. We want to
express our gratitude to the Infura team and are proud to partner with Infura as
our Ethereum node provider as SkyWeaver moves into production ops.”
- Peter Kieltyka, CEO and Chief Architect of Horizon Games

NFT.NYC left us with a lot to be excited for. Inspired by all the excitement
shared by our tournament attendees, I sat down with Chris Gonsalves, Gaming

and Michael Wuehler, Co-Founder of Infura

, to get their thoughts on what 2020 holds for crypto games and what they
believe to be the most promising NFT use cases.

Why are NFTs gaining popularity in games?
A non-fungible token (NFT) is a unique and non-interchangeable digital asset
which can be used to represent all manner of virtual and real-world goods. NFTs
are gaining popularity because they enhance in-game economies by creating
verifiable digital scarcity and allow players to own (and sell) the assets they
collect. Game items represented by NFTs allow for independent tracking of
ownership history, provenance, and other metadata. In trading card games like
SkyWeaver, this creates a trustable ownership model that follows the same
principles as Magic: The Gathering with its physical assets. You can’t fake
owning a physical asset (for the most part, sans counterfeiting) but faking
digital ownership is incredibly easy without some kind of immutable tracking
mechanism.

In addition to enhanced ownership, blockchain-based games are unlocking more
ways for players to earn and monetize their assets. New concepts emerging such
as Play2Earn will enable skilled players to earn supplemental income from their
time spent playing and create new incentive loops to deepen player engagement.

In what spheres can NFTs be used besides games?
Gaming is a great use case for NFTs, but there are other emerging uses starting
to take shape. NFTs are a type of token that can be used to represent both
digital and physical assets that are verifiably unique. Digital certifications
that represent that someone has accomplished a certain action such as voting,
attending an event, or completing a specific task is another use case that goes
beyond video games. NFTs can be used to track everything from a rare piece of
art to the sushi that ends up on your plate at a restaurant. Traceability with
the foods we eat and products we use is becoming a big area of interest. A rare
cut of Wagyu beef could be tracked using an NFT to record ownership, producer,
age, and each hop it made along the supply chain before hitting your plate.

These concepts can even expand to collectables such as a rare jersey or limited
edition FunkoPops. A Lebron James jersey off the shelf is certainly not valued
the same as one previously worn by the superstar himself. Auctioning off

authentic pieces of sports memorabilia backed by blockchain assets allows for
rarity verification, chain of ownership, and trackable metadata that will bring
more trust and extensible features to the market of collectibles.

What do you think 2020 holds for NFT crypto gaming?
More game industry veterans are founding and joining studios which are
developing games with built in blockchain features. With more talent, this will
mean the quality of the games will continue to get better and more capital will
flow to studios that have teams with decades of game experience. With the launch
of games like SkyWeaver, all new players will experience owning their first
digital asset. These players may not know at first they’re trading an NFT or
spending a stable token, but over time as they start earning these in-game
currencies and seeing the benefits of more open economies, they will be
incentivized to dig deeper and explore more games and applications built using
blockchain technologies.
