WorldEdit
Minecraft map editor and mod
WorldEdit is a powerful open-source Minecraft map editing toolkit that allows players, builders, and server administrators to quickly modify large areas of a Minecraft world directly from within the game. Instead of placing or removing blocks individually, WorldEdit provides commands and tools that enable users to select regions of the world and apply transformations to thousands or even millions of blocks at once. This capability makes it extremely useful for constructing large builds, terraforming terrain, repairing damage, or managing multiplayer server worlds efficiently. The tool includes a variety of editing methods such as brushes, shape generation commands, and clipboard operations that allow copying, pasting, and rotating entire structures. WorldEdit can run in both single-player environments and multiplayer servers and is compatible with several modding platforms and server frameworks used in Minecraft Java Edition. -

Besu Ethereum Client
An enterprise-grade Java-based, Apache 2.0 licensed Ethereum client
You can use Besu to develop enterprise applications requiring secure, high-performance transaction processing in a private network. A private network is a network not connected to Ethereum Mainnet or an Ethereum testnet. Private networks typically use a different chain ID and proof of authority consensus (QBFT, IBFT 2.0, or Clique). You can also create a local development network using proof of work (Ethash). Instructions for how to get started with developing on the Besu codebase. Please also read the wiki for more details on how to submit a pull request (PR). Besu is an Apache 2.0 licensed, MainNet compatible, Ethereum client written in Java. Participation in private networks is typically restricted in some way, so the volume of traffic is much lower than on Mainnet, resulting in lower system requirements. Depending on your environment and network setup, the minimum Java Virtual Machine (JVM) memory requirement for private networks is 4 GB. -
