NIP-15750

Nostr Coinjoin Discovery

draft author:kukks

Introduction

The BTCPay Server Coinjoin plugin offers a coinjoin endpoint discovery feature over Nostr for a coordinator runner and a coinjoin client to eaasily discover each other.

Specification

This NIP introduces a NIP16 replaceable kind 15750, with the following tags:

  • type: Signals what kind of coinjoin protocol is being provided. In the case of the BTCPay Server coinjoin plugin, this is wabisabi. Other possible options could be whirlpool, bip78, joinmarket, etc.
  • network: Signals the bitcoin network the coinjoin protocol is operating on. Always lowercase, can be mainnet,testnet, signet, regtest.
  • endpoint: A URI of where a user may connect to to interact with the coinjoin.

The content of the event COULD be used to describe the coinjoin endpoint, such as fees, round parameters, etc.

As a client, you SHOULD check that the event was created within the last 15 minutes, to ensure that the coinjoin endpoint is still active. As a coinjoin endpoint provider, you SHOULD update the event every 15 minutes to signal you are still online.
