Java has been around for a while and is well understood by companies. Ethereum is a blockchain technology that will change the way companies do business because it introduces the ability to execute code on the blockchain, known as smart contracts. Companies will want to integrate with this revolutionary technology to take advantage of the benefits of using smart contracts, but it is very time-consuming and costly to do so. The cheapest way is for companies to use technology that they know and understand well … like Java. As a Java developer, there is still an obstacle to writing smart contracts because they are typically written in a specific Ethereum programming language called Solidity.
But how can I use Java?
web3j is the java library to be integrated with the Ethereum blockchain.

The web3j project group consists of a number of different components, including:
- Maven plugin
- Gradle plugin
- Spring Boot Starter
The Maven and Gradle plug-ins provide intelligent compilation of contracts and Java code generation as part of their respective build pipelines to simplify work with smart contracts.
Furthermore, these are supported by sample projects for Maven, Gradle and Spring Boot.
There are several Ethereum clients available for use on the network. These include:
Web3j provides full support for all of them as well as working with Android.

What's this going with the business?
Web3j-quorum is an extension of web3j, designed to work with the Quorum blockchain with private authorization (J.P. Morgan fork of Ethereum).
Smart contracts are the main reason why companies are very interested in Ethereum. Smart contracts will help streamline many business processes and interactions between sectors. One could say that smart contracts exclude the intermediary. Once an intelligent contract has been written, web3j compiles the smart contract and generates a Java smart contract wrapper. Since then, all interactions with smart contracts and blockchain can be performed in Java code. This is interesting because companies can then integrate with other Java frameworks to improve their own DAPPs, such as the use of Spring to create a Web service that communicates with a blockchain.
What are we doing to make web3j enterprise friendly?
Companies must be able to understand what the blockchain is doing, without necessarily understanding how it is done. The Epirus platform provides services that companies need:
- Platform protection through easy-to-use single sign-on systems.
- Analyzing the platform by a corporate mentality, not technical.
- Platform deployment with one click.
- Provide privacy of business transactions at the blockchain level by default
- Provide tools for Java developers to interact with the platform
This reduces the barrier to entry for companies that allows you to better focus on the use of smart contracts to solve business problems.
Currently web3j is used in a number of companies including Consensys, ING and J.P. Morgan on their blockchain initiatives.

There are still very active development areas that take place on blockchain. Searching for ways to govern effectively, manage identity and perform asset transfers through blockchain continues to present opportunities for innovation in space. These are key aspects that companies must be able to provide quality products to their consumers. As these problems begin to be overcome, web3j will be there, as a gateway to the blockchain technology of ethereum, for businesses.
Ivaylo Kirilov He will conduct a workshop with Antony Denyer at the Blockchain Technology Conference on Monday 19 November for anyone wishing to look beyond the hype and gain practical experience developing with blockchain technology. Participants will learn how to use and integrate Java applications with the dominant public blockchain Ethereum.
