The goal is to demonstrate advanced bitcoin features, and make it easier for users to experiment. The intended audience has a basic awareness of how bitcoin transactions look and work. The theory of operation and full list of commands may be reviewed at https://github.com/jgarzik/txtool/blob/master/README Initially, two working examples are presented: * Easy multi-signature transaction building: https://github.com/jgarzik/txtool/blob/master/examples/multisig.txt (similar to gmaxwell's P2SH multisig example) * Passing around transactions (possibly multi-signature) for signing: https://github.com/jgarzik/txtool/blob/master/examples/tx-signing.txt Further examples such as decentralized crowdfunding and atomic coin swapping* will be demonstrated soon. * https://bitcointalk.org/index.php?topic=112007.msg1212356#msg1212356 -- Jeff Garzik Senior Software Engineer and open source evangelist BitPay, Inc. https://bitpay.com/
