Summarising each Proposal for the CoinJoin Bounty.

This summary is focused on the Proposals/Projects which came out of that thread. For a summary of all the key points in the thread see Part I.

Background

The CoinJoin Bounty BitcoinTalk thread was was started by Greg Maxwell back in 2013 in order to encourage development of implementations of CoinJoin. A 2of3 multisig donation address was created by Greg, Theymos and Pieter Wuille which was/is to be used to encourage development. As of today (2019–04–07) no payment has ever been made from this address (except to consolidate funds when fees were low). A recent comment by Theymos suggest that there may be payouts from the donated funds which now total 46.4 BTC (over $200k) — watch this space!
