[![Build Status](https://travis-ci.org/bitcoin-s/bitcoin-s-core.svg?branch=master)](https://travis-ci.org/bitcoin-s/bitcoin-s-core) [![Coverage Status](https://coveralls.io/repos/github/bitcoin-s/bitcoin-s-core/badge.svg?branch=master)](https://coveralls.io/github/bitcoin-s/bitcoin-s-core?branch=master) [![IRC Network](https://img.shields.io/badge/irc-%23bitcoin--scala-blue.svg "IRC Freenode")](https://webchat.freenode.net/?channels=bitcoin-scala)[![Gitter chat](https://badges.gitter.im/gitterHQ/gitter.png)](https://gitter.im/bitcoin-s-core) # Bitcoin-S ## Design Principles - Immutable data structures everywhere - [Algebraic Data Types](https://en.wikipedia.org/wiki/Algebraic_data_type) to allow the compiler to check for exhaustiveness on match statements - Using [property based testing](http://www.scalatest.org/user_guide/property_based_testing) to test robustness of code - Minimize dependencies to reduce attack surface ## Projects 1. `core` - this is where protocol data structures live, like [Transactions](core/src/main/scala/org/bitcoins/core/protocol/transaction/Transaction.scala), [Blocks](core/src/main/scala/org/bitcoins/core/protocol/blockchain/Block.scala), or [PrivateKeys](core/src/main/scala/org/bitcoins/core/crypto/ECKey.scala). For more info read [`core/README.md`](core/README.md) 2. `core-test` - this is where all test cases for the `core` project live 3. `rpc` - this is a RPC client implementation for `bitcoind`. For more info read [`rpc/README.md`](rpc/README.md) 4. `eclair-rpc` - this is a RPC client implementation for [Eclair](https://en.wikipedia.org/wiki/Algebraic_data_type), which is a Lightning Network implementation. For more information please read [`eclair-rpc/README.md`](eclair-rpc-README.md) 5. `bench` - benchmarks for Bitcoin-S. For more information please read [`bench/README.md`](bench/README.md) 6. `testkit` - This is a useful testkit for testing Bitcoin related applications. You can spin up Bitcoin and Lightning nodes arbitrarily and set them in specific states. For more information please read [`testkit/README.md`](testkit/README.md) 7. `zmq` - `bitcoind` has a setting that publishes information about the state of the network over ZMQ. This project implements a subscriber that allows you to read and parse that information. For more information see [`zmq/README.md`](zmq/README.md) as well as the official [Bitcoin Core ZMQ documentation](https://github.com/bitcoin/bitcoin/blob/master/doc/zmq.md) ## Artifacts You need to add the Bitcoin-S Bintray to your resolvers to be able to access published artifacts. ### sbt With sbt, this can be done like this: ```scala resolvers += Resolver.bintrayRepo("bitcoin-s", "bitcoin-s-core"), ``` Now you should be able to add Bitcoin-S artifacts like this: ```scala "org.bitcoins" % "bitcoin-s-secp256k1jni" % "0.0.3" "org.bitcoins" %% "bitcoin-s-core" % "0.0.3" withSources() withJavadoc() "org.bitcoins" %% "bitcoin-s-bitcoind-rpc" % "0.0.3" withSources() withJavadoc() "org.bitcoins" %% "bitcoin-s-eclair-rpc" % "0.0.3" withSources() withJavadoc() "org.bitcoins" %% "bitcoin-s-testkit" % "0.0.3" withSources() withJavadoc() "org.bitcoins" %% "bitcoin-s-zmq" % "0.0.3" withSources() withJavadoc() ``` ### Ammonite > Ammonite is (among other things) a modernized Scala REPL with syntax highlighting, multi-line editing, the ability to load artifacts directly in the REPL, and many other quality-of-life improvements missing in the default Scala REPL. > > Ammonite is a project by Li Haoyi, and you can get it at [ammonite.io](https://ammonite.io) With Ammonite, this can be done like this: ```scala @ import coursier.MavenRepository import coursier.MavenRepository @ interp.repositories() ++= Seq(MavenRepository("https://dl.bintray.com/bitcoin-s/bitcoin-s-core")) @ import $ivy.`org.bitcoins::bitcoin-s-core:0.0.3` import $ivy.$ @ import org.bitcoins.core.currency.Bitcoins import org.bitcoins.core.currency.Bitcoins @ Bitcoins(10) res0: Bitcoins = BitcoinsImpl(10) // 🎉 ``` This is only necessary one time, Ammonite remembers your resolvers across sessions. ### Published artifacts Versioned artifacts are available online. Snapshots (not necessarily stable, use for local development) are available at [JFrog](https://oss.jfrog.org/webapp/#/artifacts/browse/tree/General/oss-snapshot-local/org/bitcoins). Tagged versions are available at [Bintray](https://bintray.com/beta/#/bitcoin-s/bitcoin-s-core?tab=packages).
