Metaversal is a Bankless publication for weekly level-ups on NFTs, digital worlds, and extra!
Expensive Bankless Nation,
There’s a brand new decentralized venture on the town, and I imagine its attain will finally prolong far and large.
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 instances can be so various.
I’m speaking in regards to the Ethereum Attestation Service, or EAS.
For in the present day’s submit 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 enable individuals or teams to vouch for sure data.
Towards this finish, EAS makes use of a set of sensible contracts on Ethereum to offer a structured and standardized method to those attestations, guaranteeing their authenticity and integrity.

EAS is designed to instill belief in on-line interactions.
In our digital age, the place information is omnipresent and deepfakes and scams are on the rise, guaranteeing authenticity and accuracy is shortly turning into important.
Accordingly, EAS provides a mechanism to confirm information, set up its authenticity, and guarantee its integrity on Ethereum, which in flip additionally makes this information composable (i.e. web3 apps can use as constructing blocks) and brazenly obtainable to the general public.
At a basic stage, then, EAS is right for verifying digital identities — i.e. guaranteeing 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 unique and never counterfeit or plagiarized.
The EAS capabilities by way of two sensible contracts, the primary of which is targeted on schema registration and the second of which is targeted 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, information is structured accordingly, signed to supply a digital signature, after which submitted to EAS. After verification in opposition to the schema, the attestation is recorded on the blockchain.
Notably, EAS accommodates each onchain and offchain attestations. Onchain attestations are immediately logged on the Ethereum blockchain, providing strong safety and immutability, and is right for information necessitating sturdy belief assurances.
Conversely, offchain attestations, whereas anchored to the blockchain, are saved externally, e.g. by way of IPFS. This method is sweet for big information 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, however 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 identification service, which verifies consumer achievements and participation.
The EAS can tackle a myriad of challenges throughout varied sectors.
To make sure, one low-hanging fruit right here is the verification of digital credentials, starting from academic levels to skilled certifications, for which EAS provides a decentralized resolution for authentication.
Past credentials, although, EAS also can play a pivotal function in roles and authorizations inside teams and organizations, because the service can supply a tamper-proof mechanism to verify that people possess the mandatory permissions and entry rights.
Moreover, and what I’m maybe most excited by personally, is how EAS can be utilized to ascertain verifiable status techniques on on-line platforms and marketplaces. Via 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 points make them much less appropriate for explicit use instances 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 boost belief, validation, and the interoperability of digital information. That mentioned, EAS and NFTs, although distinct, can completely be extremely complementary as a result of NFTs are and at all times can be surrounded by information that might profit from attestations.
As an illustration, you may 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 means of their NFTs, guaranteeing authenticity of onchain memorabilia elements made alongside the best way. EAS also can 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 excited by EAS and status 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 status system, JXPG, proper into our Canonicon NFT. The issue? It was nonstandardized and siloed to that NFT assortment.
In distinction, EAS provides a simple option to construct a status system round any NFT venture and in a standardized manner 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 just simply maintain into “vertical” belongings that may observe your achievements over time!
