Identity Standard

I’d like to propose an identity standard for AEternity

We created an Ethereum legally binding ID in Brazil by partnering with Certisign, the largest CA of the country

The project started as this POC on ETHBuenosAires and we were one of the winners of the Hackaton

We created it using EIP/ERC 1078, 1077, 735, 725
Those standards were used as the foundation for universallogin.io

Alex Van de Sande assisted us in the creation of our product and is keen on pushing this idea further onto other blockchains

## Abstract

This presents a method to replace the usual signup/login design pattern with a minimal ethereum native scheme, that doesn’t require passwords, backing up private keys nor typing seed phrases. From the user point of view it will be very similar to patterns they’re already used to with second factor authentication (without relying in a central server), but for dapp developers it requires a new way to think about ethereum transactions.


## Simple Summary

The unique identifier of the user is a contract which implements both Identity and the Executable Signed Messages ERCs. The user should not need provide this address directly, only a ens name pointing to it. These types of contracts are indirectly controlled by private keys that can sign messages indicating intents, which are then deployed to the contract by a third party (or a decentralized network of deployers).

I think that the main value proposition besides having and ID with claims on it, is the UX that can be created by leveraging meta-transactions. Users can use the blockchain without having to understand it, all you need to do is remember your AENS address and authorise it on another device, the same way 2factor authentication implementations already works.

Any AEPP could leverage it to streamline the sign-in/up on boarding process, the service we created for example, would pay for all the gas cost of the transactions, so the user wouldn’t even have to ever hold any ETH.

Please let me know if it makes sense for AEternity and if you are interested

Hey @gabrielo, thank you for this proposal.

@bruteforce.chain or @philipp.chain, do you have an opinion on that?
