One year ago, we were fortunate enough to receive a new grant from the Ethereum Foundation to help us further our work on the Web3j library and related tooling. As with much Open Source software, it can be challenging to maintain which is why such funding is helpful. In this

This is your high level guide to creating a private payment network. You create these because you want instant trade settlement with full allocation clarity, and you do it to avoid other more costly traditional event based solutions, like Swift. Private payment networks are taking the world by storm. We’

Bitcoin and Ethereum are the biggest public permissionless blockchain networks in the world, measured by the value of their native tokens. But are you familiar with the software that makes these blockchain networks operate?  A blockchain network consists of multiple node software instances which are running on different computers. These

Ethereum is a network of nodes, and in a fully decentralised world you’d be running your own node locally and connect to that when making transactions or querying for data.  However, not everyone can or wants to run their own node, and because of this we have infrastructure providers

Today is the first time Web3 Labs have released the Ethereum smart contract deployment library and Gradle plugin for Web3j. This release of the Web3j deployer library and plugin, available at GitHub, allows for easy to use deployment process logic following an annotation driven approach. As can be found in

Decentralised identity and verified credentials enable you to identify yourself online, without needing to scan your passport or expose personal information unduly. It enables organisations to know who they are dealing with more efficiently. It allows us to build trust between multiple parties. It allows for this through innovative use

In the last blog post, I compared Ethereum’s technical capabilities to Bitcoin. It made a pretty strong case, showcasing that Bitcoin and Ethereum are a generation apart. Ethereum gained the superiority title for two main reasons - * For introducing the ability to run smart contracts  * For boasting a community

Blockchains and DLTs can be viewed from two angles. One is purely technical, and one is purely economical. In this two-part series, I’ll be outlining the arguments for why we believe that Ethereum, both as a technical and economic system, is superior to Bitcoin. In this blog. I'

In my previous post, we looked at the web3j-unit and web3j-evm libraries. These are tools that help you test your Solidity smart contracts using Web3j and Java. In this blog post we’ll spend some more time looking at the console debugger you find in the web3j-evm library.  The console

As a developer, I’m sure you strive to test what you develop, and in most established programming languages you have a box full of tools to pick from. In the world of blockchain, the box is still being built however, and the maturity of the available tools reflects this.
