SIP describing Stacks message signing

opened 12:18PM - 06 Oct 22 UTC

No SIP exists describing how arbitrary messages are signed. Specifics such a…s what the prefix is, and what encoding is used should be described. [`EIP-712`](https://eips.ethereum.org/EIPS/eip-712#arbitrary-messages), for example, has an arbitrary message section. The current prefix follows the same format as `EIP-712`, with Stacks in place of Ethereum. ``` "\x17Stacks Signed Message:\n" ‖ len(message) ‖ message ``` The need for this SIP comes from issues that've arisen migrating to a single prefix: See https://github.com/hirosystems/stacks.js/issues/1328. In migrating to a new prefix, some apps have seen breaking changes. Were this described in a SIP, a more structured, community-driven approach to changes would've been required. cc/ @friedger @markmhx @MarvinJanssen @pradel @Hero-Gamer

Just wanna help bring this SIP issue on Github to Stacks Forum, track the need of the SIP/ gauage opinions.
It is related to SIP-018 Signed Structured Data by MarvinJanssen · Pull Request #57 · stacksgov/sips · GitHub

Please feel free to comment so we can get this SIP moving or have it integrated into SIP-018, or otherwise.
