EAS Explained 📑 – by William M. Peaster

Metaversal is a Bankless publication for weekly level-ups on NFTs, digital worlds, and extra!

Pricey Bankless Nation,

There’s a brand new decentralized challenge on the town, and I consider its attain will finally lengthen far and broad. 

It’s token-less, and doesn’t depend on NFTs for its infra. 

So why am I speaking about it right here? As a result of in time I believe this method will come for use in tandem with many NFT tasks as a result of its use circumstances will probably be so diversified. 

I’m speaking in regards to the Ethereum Attestation Service, or EAS. 

For right now’s publish let’s break down what this service is and what it means for NFTs!

The Ethereum Attestation Service (EAS) is a decentralized system constructed to facilitate the creation, administration, and verification of attestations. 

In essence, attestations are digital signatures, i.e. digital stamps of approval, that permit individuals or teams to vouch for sure data. 

Towards this finish, EAS makes use of a set of sensible contracts on Ethereum to supply a structured and standardized method to those attestations, making certain their authenticity and integrity.

EAS is designed to instill belief in on-line interactions. 

In our digital age, the place knowledge is omnipresent and deepfakes and scams are on the rise, making certain authenticity and accuracy is shortly changing into important. 

Accordingly, EAS presents a mechanism to confirm knowledge, set up its authenticity, and guarantee its integrity on Ethereum, which in flip additionally makes this knowledge composable (i.e. web3 apps can use as constructing blocks) and overtly obtainable to the general public. 

At a basic stage, then, EAS is good for verifying digital identities — i.e. making certain on-line  profiles and personas are real — and verifying content material authenticity — i.e. confirming that content material, be it an article, picture, or video, is authentic and never counterfeit or plagiarized. 

The EAS capabilities by way of two sensible contracts, the primary of which is concentrated on schema registration and the second of which is concentrated on attestation creation. 

Merely put, schemas act as blueprints, defining the format and construction of the info to be attested. As soon as a schema is in place, knowledge is structured accordingly, signed to provide a digital signature, after which submitted to EAS. After verification towards the schema, the attestation is recorded on the blockchain.

Notably, EAS accommodates each onchain and offchain attestations. Onchain attestations are instantly logged on the Ethereum blockchain, providing sturdy safety and immutability, and is good for knowledge necessitating robust belief assurances. 

Conversely, offchain attestations, whereas anchored to the blockchain, are saved externally, e.g. by way of IPFS. This method is nice for big knowledge units or when privateness issues require offchain storage. Whatever the methodology right here, although, EAS ensures an attestation’s integrity and authenticity.

Optimism has been one of many foremost early adopters of EAS tech. For instance, not solely has the layer-two (L2) scaling resolution used the system to underpin its personal AttestationStation service, nevertheless it additionally now predeploys the EAS contracts to new chains constructed with OP Stack tech, e.g. Base. 

Moreover, decentralized regen grants and bounties platform Gitcoin makes use of EAS for onchain stamping in its Gitcoin Passport id service, which verifies person achievements and participation.

The EAS can deal with a myriad of challenges throughout numerous sectors. 

To make sure, one low-hanging fruit right here is the verification of digital credentials, starting from instructional levels to skilled certifications, for which EAS presents a decentralized resolution for authentication. 

Past credentials, although, EAS may play a pivotal function in roles and authorizations inside teams and organizations, because the service can provide a tamper-proof mechanism to verify that people possess the mandatory permissions and entry rights. 

Moreover, and what I’m maybe most inquisitive about personally, is how EAS can be utilized to determine verifiable popularity techniques on on-line platforms and marketplaces. By way of these techniques, customers can work together with friends they don’t know but with belief primarily based on previous attested actions. 

Whereas NFTs signify a giant advance for digital belongings, their inherent transferability and different distinctive elements make them much less appropriate for specific use circumstances like credentials the place EAS can shine. 

Once more, in contrast to tokens that signify digital belongings, EAS attestations function digital signatures on structured data. Their main objective is to reinforce belief, validation, and the interoperability of digital knowledge. That stated, EAS and NFTs, although distinct, can completely be extremely complementary as a result of NFTs are and at all times will probably be surrounded by knowledge that might profit from attestations.  

As an illustration, you’ll be able to arrange a schema with a resolver contract in order that, say, NFTs are minted to individuals of an occasion as sure attestation standards are met.

However past this, the probabilities listed below are restricted solely by our imaginations. Artists can use EAS to attest to the creation strategy of their NFTs, making certain authenticity of onchain memorabilia parts made alongside the best way. EAS may facilitate decentralized licensing techniques for NFT IP, and even facilitate NFT-based land registries to make sure the authenticity and transferability of the land parcels concerned. 

Earlier I had talked about I used to be inquisitive about EAS and popularity techniques and that’s as a result of I used to work with one up shut. Once I was at JPG, an NFT curation protocol, we caked a curatorial popularity system, JXPG, proper into our Canonicon NFT. The issue? It was nonstandardized and siloed to that NFT assortment. 

In distinction, EAS presents an easy strategy to construct a popularity system round any NFT challenge and in a standardized means that anybody can look to, get pleasure from composability from, and so forth. That’s highly effective and one compelling avenue to transform NFTs from “horizontal” easy belongings that you simply simply maintain into “vertical” belongings that may observe your achievements over time!
