Transitioning from Ledger to Database

[davideroffo]

Good morning, everyone,

I'm curious to know if it's feasible to transition from a ledger-based system to a database-centric approach while utilizing Aries. This transition would enable us to reduce our reliance on a blockchain infrastructure and instead leverage the advantages of a standard database.

By making this shift, we aim to gain more control over our data management processes. Aries has been a valuable tool in our toolkit, and we're exploring ways to adapt it to better suit our needs.

Has anyone here had experience with such a migration or have insights into the feasibility and best practices involved? Your expertise and guidance would be greatly appreciated.

Thank you

@genaris has created a did:web implementation for hosting AnonCreds resources, which would allow you to host your schemas and credentials definitions on a webserver (backed by a DB for example).

Would something like that work for you?

[TimoGlastra]

Of course, you can also adopt W3C credentials and use did:web / other non-blockchain DID methods and this would also get you fully of the blockchain.

The first option you mentioned seems to be the one we are looking for. Do you know where I can find some resources / docs on it?

@genaris wrote a spec for it: https://hackmd.io/dzK5FbIsSkGlfnLPF_hAeQ, and an implementation for AFJ: https://github.com/2060-io/aries-javascript-didweb-anoncreds?tab=readme-ov-file

Thanks Timo. Just as a note: the spec is currently being maintained in https://github.com/2060-io/did-web-anoncreds-method. I've just updated the link in the implementation repo.
