Philosophy

Bitcoin-S is a loosely coupled set of cryptocurrency libraries for the JVM. They work well together, but also can be used independently. This project's goal is NOT to be a full node implementation, rather a set of scalable cryptocurrency libraries that use industry standard tools (rather than esoteric tech often found in cryptocurrency) where possible to make the lives of professional software engineers, security engineers, devops engineers and accountants easier. We are rapidly iterating on development with the goal of getting to a set of stable APIs that only change when the underlying bitcoin protocol changes.

If you are a professional working a cryptocurrency business and have feedback on how to make your lives easier, please reach out on slack, gitter or twitter!

REPL

You can try out Bitcoin-S in a REPL in a matter of seconds. Run the provided "try bitcoin-s" script, which has no dependencies other than an installed Java 8. The script downloads and installs Coursier and uses it to fetch the Ammonite REPL and the latest version of Bitcoin-S. It then drops you into immediately into a REPL session.

$ curl -s https://raw.githubusercontent.com/bitcoin -s /bitcoin -s /master/try-bitcoin-s.sh | bash Loading... Welcome the Bitcoin-S REPL, powered by Ammonite Check out our documentation and examples at https://bitcoin-s.org/docs/getting-started @ val priv = ECPrivateKey() @ val pub = priv.publicKey @ val spk = P2WPKHWitnessSPKV0(pub) @ val address = Bech32Address(spk, MainNet) @ address.value res4: String = "bc1q7ynsz7tamtnvlmts4snrl7e98jc9d8gqwsjsr5"

Getting prebuilt JARs

If you want to add Bitcoin-S to your project, follow the instructions for your build tool

sbt

Add this to your build.sbt :

libraryDependencies += "org.bitcoin-s" % "bitcoin-s-secp256k1jni" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-core" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-chain" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-bitcoind-rpc" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-eclair-rpc" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-key-manager" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-node" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-wallet" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-testkit" % "0.3.0" libraryDependencies += "org.bitcoin-s" %% "bitcoin-s-zmq" % "0.3.0"

Nightly builds

You can also run on the bleeding edge of Bitcoin-S, by adding a snapshot build to your build.sbt . The most recent snapshot published is 0.3.0+422-bd94ff15+20200901-0943-SNAPSHOT .

To fetch snapshots, you will need to add the correct resolver in your build.sbt :

resolvers += Resolver.sonatypeRepo( "snapshots" )

The official maven repo for releases is

https://repo1.maven.org/maven2/org/bitcoin-s/

The repo for snapshots, which are published after everytime something is merged to master:

https://oss.sonatype.org/content/repositories/snapshots/org/bitcoin-s/
