Metaversal is a Bankless publication for weekly level-ups on NFTs, digital worlds, and extra!
Expensive Bankless Nation,
There’s a brand new decentralized challenge on the town, and I imagine its attain will ultimately lengthen 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 feel this technique will come for use in tandem with many NFT tasks as a result of its use circumstances will likely be so diverse.
I’m speaking concerning the Ethereum Attestation Service, or EAS.
For at the moment’s put up 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 info.
Towards this finish, EAS makes use of a set of good contracts on Ethereum to offer a structured and standardized strategy 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 turning into important.
Accordingly, EAS affords 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 accessible to the general public.
At a basic degree, 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 unique and never counterfeit or plagiarized.
The EAS features by way of two good 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 in opposition to 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 strong safety and immutability, and is good for knowledge necessitating sturdy belief assurances.
Conversely, offchain attestations, whereas anchored to the blockchain, are saved externally, e.g. by way of IPFS. This strategy is sweet for giant knowledge units or when privateness concerns require offchain storage. Whatever the technique 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 consumer achievements and participation.
The EAS can handle a myriad of challenges throughout numerous sectors.
To make certain, one low-hanging fruit right here is the verification of digital credentials, starting from instructional levels to skilled certifications, for which EAS affords a decentralized resolution for authentication.
Past credentials, although, EAS can even play a pivotal function in roles and authorizations inside teams and organizations, because the service can supply a tamper-proof mechanism to substantiate that people possess the mandatory permissions and entry rights.
Moreover, and what I’m maybe most thinking about personally, is how EAS can be utilized to ascertain verifiable repute methods on on-line platforms and marketplaces. By these methods, customers can work together with friends they don’t know but with belief based mostly on previous attested actions.
Whereas NFTs signify an enormous advance for digital property, their inherent transferability and different distinctive points make them much less appropriate for specific use circumstances like credentials the place EAS can shine.
Once more, not like tokens that signify digital property, EAS attestations function digital signatures on structured info. Their main goal 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 likely be surrounded by knowledge that might profit from attestations.
As an example, you’ll be able to arrange a schema with a resolver contract in order that, say, NFTs are minted to contributors of an occasion as sure attestation standards are met.
However past this, the chances listed below are restricted solely by our imaginations. Artists can use EAS to attest to the creation means of their NFTs, making certain authenticity of onchain memorabilia parts made alongside the best way. EAS can even facilitate decentralized licensing methods 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 thinking about EAS and repute methods 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 repute system, JXPG, proper into our Canonicon NFT. The issue? It was nonstandardized and siloed to that NFT assortment.
In distinction, EAS affords an easy option to construct a repute system round any NFT challenge and in a standardized approach 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 property that you simply simply maintain into “vertical” property that may observe your achievements over time!
