EAS Resolver fees research

Description

Research and vulgarization about Ethereum Attestation Service (EAS ) and resolver fees.

Problem

The EcoID protocol team started to work on a V2 of the EcoID. If we succeed to prove that EAS is a better alternative than the current EcoID V2 draft, we might make the team save a decent amount of time.

One of the promising opportunities opened by EcoID is the fact that Verifier can build a business on top of the protocol by charging fees to the receiver of their attestations.

If the Ethereum Attestation Service looks like a promising alternative to EcoID, we need to first validate that EAS offers us an equivalent solution.

Why

Eco id currently comes with a set of limitations :

1. No standardization

2. Only used within the Eco community

3. High Fees

   1. only available on Ethereum

   2. only possible to make one attestation at a time

4. All claims rely on trusting the Verifier making the attestation

5. Not permissionless: a receiver needs to give its approval

6. EcoID playground is currently the only tooling available

On the other side, EAS overcomes the following limitations:

1. Attestation is enforced through schemas

2. Organization following EAS :

   1. Founded by Ethereum Foundation

   2. Live on Arbitrum mainnet

   3. Live on Optimism Goerli, will be live on mainnet on the 6th of June 2023

   4. Live on Coinbase : Base Goerli

3. Cheaper fees

   1. Available on L2

   2. Batchable: multiple attestations can be made at once, reducing fees

4. Trust can be trustless, or Permissionless

5. EAS shipped with nice tooling :

   • An attestation explorer for anyone to verify attestations

   • A no-code schema builder for easily creating schemas

   • A no-code attestation maker to easily make attestations

   • An SDK for increasing the speed for devs to experiment & integrate EAS

   • The ability to make verifiable off-chain attestations.

   • Developer documentation to get started for all levels of technicality

   • Educational resources to understand EAS

Success

We want to highlight the possibilities and limitations of the Ethereum Attestation Service (EAS) protocol to fulfill an equivalent of the EcoID capability :

• allowing Verifiers to develop business via a fee-per-attestation mechanism.

Audience

Eco****ID protocol team

Details

The strategy will take place in 3 distinct steps :

1. Build a working example

2. Documenting the process

   The 2 first steps will be the example of a Verifier paid in ECO Token via a Free Resolver

Roadmap

If this proposal gets approved, the following deliverables will be shipped within a 3 weeks time frame after approval.

Deliverables & added value

• A working example of a Verifier receiving ECO Token by delivering an attestation to a Receiver paying the fees as illustrated in the diagram above

• GitHub Repo

• User Guide: how to reproduce (deployment, schema attestation, attestation generation getting paid in Eco)

• User Flow to illustrate the process

Further development

In case that EAS provides a similar feature:

Funding

We request a budget of 2500$ worth of Eco token at the time of the payment.

Founds destination

The team will send the payment request and detail about its distribution after the project delivery if accepted.
