This document extends the app dev OP_RETURN convention described here.
If you are a developer using an OP_RETURN prefix for your app, please claim your protocol identifier by submitting a diff to this repo, including:
- A display name for the protocol
- An author (or list of authors)
- A URL pointing to the specification of the protocol
- An eCash address (to avoid ambiguity and to later modify names / authors / URL)
Protocol identifiers below are listed how they appear in eCash transaction outputs.
