Ethers.js is a simple, compact and complete JavaScript (via TypeScript) library for interacting with Ethereum and related blockchains. It is currently used in a very large number of Blockchain projects, including everything from block explorers to wallets (like MetaMask) and is downloaded over 7.1 million times per month (as of this writing). It is also one of the top 500 projects (by dependants) on NPM. It was written and is maintained by me, RicMoo (Richard Moore), a random developer from Canada that is passionate about open-source and dedicates most his waking-time (and some sleeping-time) to it. Hack the Planet! :)

The rust implementation of libp2p. Libp2p is a modular framework for a variety of p2p protocols. These protocols are used widely by a variety of projects to establish p2p communications in a decentralized manner. The rust implementation is used by a variety of projects in the space including, Magi (OP Stack rollup client), Lighthouse (Ethereum consensus client) and Forest (Filecoin client). The rust implementation specifically, is used by a variety of projects in the

The canonical Golang implementation of libp2p. Go-libp2p is a collection of protocols that support a wide range of functionalities, such as; connection establishment, remote node protocol identification and negotiation (through its identify protocol), data encryption, content/peer discovery (through its Kademlia DHT component), and data transfer through its pub-sub protocol (Gossipsub). The stakeholders of go-libp2p include the Interplanetary Shipyard team who maintain this implementation as well as projects that depend on go-libp2p like Optimism's op-node (the reference implementation of the rollup-node spec), the Ethereum Beacon Chain (via Prysm, the Go consensus client), Filecoin (Lotus and Venus), Celestia node, and many more: https://github.com/libp2p/go-libp2p?tab=readme-ov-file#notable-users.
