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.

IPFS (InterPlanetary File System) is a peer-to-peer protocol designed to make the web faster, more open, and more resilient. By using content-addressed storage rather than location-based references, IPFS removes the need for centralized servers and allows files to be distributed and retrieved from multiple nodes around the world. This approach lowers hosting costs, improves data availability, and reduces censorship, laying the groundwork for a more secure and permanent global information network. IPFS is used in a variety of applications. While some users interact with IPFS via imported libraries in their projects, a large amount of usage comes via IPFS' HTTP Gateway API which allows users to self-host, use extensions like IPFS companion, or publicly run gateways (whether paid ones run by companies like Filebase, Pinata, etc. or the public goods services at ipfs.io and dweb.link). IPFS is a system for moving data across decentralized networks, with >11M weekly users and 250K public p2p nodes. Highlights: Off-chain storage. IPFS provides verifiable, off-chain storage, often used to reduce on-chain needs in Ethereum & Optimism. Examples: TrueBlocks (local IPFS-based index for EVM chains, built with grants from OP & EF), Snapshot (IPFS-based off-chain voting). Go-to distribution network for fully decentralized third-party app frontends (for gaming, DeFi, & more). We run gateway services that serve 900M requests/wk, and added native IPFS support to browsers like Chromium & Brave. NFT metadata gold standard. Over 115M NFTs are stored on IPFS, including leading platforms OpenSea (which supports Optimism NFTs), Rarible, and Zora.

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
