Java Blockchain Libraries Developing a blockchain in Java makes it portable across various devices because it uses plugin-architecture, which means it is possible to develop several blockchain-based components in parallel. Blockchain technologies are considered highly secure for the cryptocurrency universe because of their distributed ledger property. In the blockchain world, java is considered one of the best blockchain programming languages because of its reliable frameworks of Hyperledger Fabric and Web3j. In addition, the JIT and GC functionalities make the Java runtime environment highly time efficient, which is highly preferable for Java developers. Bitcoinj library allows the user to keep a Bitcoin wallet and a ledger of transactions that do not need a local copy. The bitcoin-wallet library is an exclusive code package meant for Android-based Bitcoin applications. The functionality to manage Hyperledger lifecycle is provided to the developer by the library fabric-sdk-java. Listed below are some interesting Java libraries for blockchain applications that provide handy code packages for ready implementation.
