BIP-340 Taproot signature #274

Open MSghais opened 3 days ago

MSghais commented 3 days ago

Description

Create a Nostr private key and public key BIP-340 Taproot compatible. Encrypt data in a contract?

Idea, research need to be done on it.

Not sure if it's possible but look cool:

[] Linked smart contract to link starknet account to a nostr private key
[ ] Maybe create an AA account of Nostr managed by the Starknet account or a Nameservice.
[ ] - Generate a private key for BIP-340
[ ] - encrypt it for a starknet account in a smart contract or AA
[ ] can sign a Nostr event
[ ] pass recovery for Nostr
[ ] Tests

Hi , can i take this up? I have on project which implemented ECDSA signatures before but I need to learn about Nostr to work on this

baitcode commented 3 days ago

Would love to do the research and publish results as PR with code or README.md in case it is not possible to implement.

Can I contribute to this one?

Can i work on this, i have worked on similar things before

First I will add the ability to derive Taproot-compatible private and public keys, in BIP-340, to the system Encrypt Private Key: Take the public key of the Starknet account and use it to encrypt the BIP-340 private key. Securely store it within a smart contract or AA wallet Link Nostr & Starknet:

Create a smart contract that links the Starknet account with the Nostr-derived private key, so Nostr can sign events via Starknet. Research adding a name service for identity management.

Recovery Mechanism: Design recovery flow allowing restoration of keys via Starknet, if possible.

Testing: Test the generation of keys, encryption, and signature over Nostr events. For each contract function, write tests.

Could I take over this issue?

@MSghais Could you provide a bit more details?

What exactly are you trying to achieve? Please provide the description of functionality. For example: I want to be able to handle workflow triggered by something. The workflow will extract Nostr event, sign it on behalf of someone and submit somewhere. The scope of task Is very unclear atm.
You can definitely store mapping from Nostr address to Starknet address.
Encrypting Nostr secret key and storing it onchain does not sound like a good idea, and I belive it's against general security guidelines. If you can decrypt it then how user controls what you do with it? If only user can decrypt, why would they store it onchain?
