In the first version the client API was contained within the libbitcoin-server library, which led to a dependency between client applications such as [[Bitcoin_Explorer|Bitcoin Explorer]] (bx), and the server library.<br /> <br /> * In the summer of 2014 William Swanson redesigned the client library as libbitcoin-client. The first release of the independent library shipped as version 2.0 coincident with Bitcoin Explorer 2.0. This was a client to Obelisk, the original server application. As Obelisk was upgraded to Bitcoin Server (version 2.0) the client (version 2.1) was adapted to minor corresponding changes in the client-server API.<br /> <br /> ==Dependencies (Version2)==<br /> * [http://www.boost.org boost]<br /> * [https://github.com/bitcoin/secp256k1 secp256k1]<br /> * [https://github.com/jedisct1/libsodium sodium]<br /> * [https://github.com/zeromq/libzmq zmq]<br /> * [https://github.com/zeromq/czmq czmq]<br /> * [https://github.com/zeromq/czmqpp czmqpp]<br /> * [[Libbitcoin_Common|libbitcoin]]<br /> <br /> ==Dependencies (Version3)==<br /> * [http://www.boost.org boost]<br /> * [https://github.com/bitcoin/secp256k1 secp256k1]<br /> * [https://github.com/zeromq/libzmq zmq]<br /> * [[Libbitcoin_Protocol|libbitcoin-protocol]]<br /> * [[Libbitcoin_Common|libbitcoin-system]]<br /> <br /> ==See Also==<br /> * [[Libbitcoin]]<br /> <br /> ==References==<br /> <br /> [[Category:Clients]]<br /> [[Category:Open Source]]<br /> [[Category:Software‏‎]]</div> Evoskuil https://en.bitcoin.it/w/index.php?title=Libbitcoin_Build&diff=68496 Libbitcoin Build 2021-03-09T01:22:18Z <p>Evoskuil: /* Example Repository Model */ remove SWIG</p> <hr /> <div>The [https://github.com/libbitcoin/libbitcoin-build libbitcoin-build] repository is used by [[Libbitcoin]] maintainers to generate [http://en.wikipedia.org/wiki/GNU_build_system Autotols] and other build artifacts from declarative sources.

Contributors to a given repository can edit the generated artifacts and later maintainers can determine whether to retain changes by incorporating them into the model. This allows less experienced contributors to introduce changes for review without introducing fragility into user-facing build, install and packaging processes.<br /> <br /> ==Example Repository Model==<br /> &lt;repository name=&quot;libbitcoin-consensus&quot;

They allow transactions to be sent to a script hash ([[address]] starting with 3) instead of a public key hash (addresses starting with 1). To spend bitcoins sent via P2SH, the recipient must provide a [[script]] matching the script hash and data which makes the script evaluate to true.<br /> <br /> Using P2SH, you can send bitcoins to an address that is secured in various unusual ways without knowing anything about the details of how the security is set up. You just send bitcoins to the ~34-character P2SH address. The recipient might need the signatures of several people to spend these bitcoins, or a password might be required, or the requirements could be completely unique.<br /> <br /> == Addresses ==<br /> <br /> [[BIP 0013|BIP 13]] specifies the address format. Bitcoin P2SH addresses always start with &lt;code&gt;3&lt;/code&gt;.<br /> <br /> == Example ==<br /> <br /> Transaction 40eee3ae1760e3a8532263678cdf64569e6ad06abc133af64f735e52562bccc8 paid to P2SH address 3P14159f73E4gFr7JterCCQh9QjiTjiZrG.
