Guide Kit Bitcoin is at the stage of mass adoption. The entire crypto ecosystem is being used to bring innovative solutions to existing world problems.
Now, various Java libraries can be used to build popular Bitcoin components. With the help of these libraries, developers can build bitcoin wallets, private key management solutions, automate cryptocurrency trading, build games with the Bitcoin economy, and even create a mining setup.
If you’re looking to incorporate blockchain in your Java project, here’s a breakdown of 3 of the major Bitcoin libraries. BitcoinJ is a Java implementation of the Bitcoin protocol through which you can maintain a Bitcoin wallet and send/receive transactions without requiring a local copy of Bitcoin core. While it’s implemented in Java, we have examples in Python and JavaScript, both of which are JVM compatible. We also have bisq-network, which is a private and decentralized method to exchange fiat for Bitcoin using P2P networking and multi-signature escrow. Exchange-core is an ultra-fast matching engine based on LMAX Disruptor, Real Logic Agrona, OpenHFT, Eclipse Collections (like Goldman Sachs GS Collections), and Adaptive Radix Trees. If you expect high-load conditions and pauseless 24/7 operation, it’s the one to go with.
