<p>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.</p>
<p>If you are a professional working a cryptocurrency business and
have feedback on how to make your lives easier, please reach out on <a href="https://join.slack.com/t/suredbits/shared_invite/zt-eavycu0x-WQL7XOakzQo8tAy7jHHZUw">slack</a>,

<p>You can try out Bitcoin-S in a REPL in a matter of seconds. Run the provided
<a href="https://github.com/bitcoin-s/bitcoin-s-core/blob/master/try-bitcoin-s.sh">&quot;try bitcoin-s&quot;</a>
script, which has no dependencies other than an installed <em>Java 8</em>. The script
downloads and installs <a href="https://get-coursier.io/">Coursier</a> and uses it to
fetch the <a href="https://ammonite.io">Ammonite</a> REPL and the latest version of
Bitcoin-S. It then drops you into immediately into a REPL session.</p>

adding a snapshot build to your <code>build.sbt</code>. The most
recent snapshot published is <code>0.3.0+422-bd94ff15+20200901-0943-SNAPSHOT</code>.</p>

<p>If you want to build Bitcoin-S JARs yourself, you need to use the
<a href="https://www.scala-sbt.org/">sbt</a> build tool. Once you have sbt
installed, run <code>sbt publishLocal</code>. This places the required JAR
files in your <code>.ivy2/local</code> folder. On Linux, this is located at
<code>$HOME/.ivy2/local/</code> by default.</p>
