11 best Java Ethereum libraries in 2023

Ethereum is a decentralized platform for running smart contracts, which are self-executing contracts with the terms of the agreement between buyer and seller being directly written into lines of code. It is possible to create applications that communicate with the Ethereum blockchain and smart contracts using the popular programming language Java. Java is used to develop various applications that interact with the Ethereum blockchain and smart contracts. Some applications of combining Java and Ethereum are shown below: 

1. Decentralized finance (DeFi) applications: Java may be used to create decentralized finance (DeFi) apps like stablecoins, lending and borrowing platforms, and decentralized exchanges (DEXes). 
2. Supply chain management: Java can create applications and smart contracts that streamline and automate supply chain operations. 
3. Identity and authentication: Smart contracts and applications that support safe and decentralized identity verification and authentication can be created using Java. 
4. Voting systems: By recording and verifying votes on the Ethereum blockchain, Java may be used to create safe, transparent voting systems. 

Web3j, Besu, Upchain-wallet, and EthereumJ are just a few Java libraries available for use with Ethereum. These libraries offer a variety of capabilities and features for dealing with the Ethereum blockchain, including the ability to develop and deploy smart contracts, conduct transactions, integrate Ethereum nodes, manage accounts, and handle events via observable streams.
