ECDHM Address: Elliptic Curve Diffie-Hellman-Merkle (ECDHM) addresses are Bitcoin address schemes that increase privacy. ECDHM addresses can be shared publicly, and are used by senders and receivers to secretly derive traditional Bitcoin addresses that passive blockchain observers cannot predict. The result is that ECDHM addresses can be "reused" without the loss of privacy that usually occurs from traditional Bitcoin address reuse.
JoinMarket: JoinMarket is a market for CoinJoin participants.
CoinShuffle: CoinShuffle is an extension to the CoinJoin protocol.
CoinJoin: CoinJoin is a privacy protocol that protects Bitcoin transaction privacy by allowing multiple parties to send funds within a single transaction without the risk of theft.
