Crypto && Coffee 054

Technology Recap: 


  • In a recent thread, Chris Belcher announced that the first multi-transaction CoinSwap has been created on the Bitcoin testnet. Following the CoinSwap protocol, the actual transfer of coins takes place off-chain even though they are still unspent on-chain. The protocol is non-custodial and prevents Alice and Bob from stealing each other’s money at any point in the process. The multi-transaction use-case is to avoid amount correlation. 
  • The next step for CoinSwap on Bitcoin testnet is to incorporate ECDSA-2P which allows the creation of a 2-of-2 multi-sig address that looks the same as a regular single signature address such as P2PKH.
