Swarm is a distributed storage platform and content distribution service, built on Ethereum Blockchain with native token called as BZZ. Swarm users upload data to the network and such data is split into small chunks.

Incentives make sure that node operators will be rewarded for discovery, storage and propagation of chunks. Swarm Accounting Protocol (SWAP) ensures that node operators collaborate in routing messages.

ZetaSeek (user specific search engine), Upala (unique identity for dApps), Waggle (spam free, decentralized email service) and Swarmify (decentralized music streaming) are projects that are being built on Swarm.
