The Interplanetary File System (IPFS) is a decentralized network protocol for sharing hypermedia in a distributed file system. IPFS can be used to link blockchain transactions This effectively timestamps and secures the content, without having to put the data on the chain itself. Filecoin, an IPFS-based decentralized storage cloud, is closely related with the IPFS protocol, and provides the incentive system.

FOAM is developing a blockchain-based location service protocol for embedding physical locations in Ethereum smart contracts. The FOAM network will use radio beacons and will provide incentives for decentralized location services that will be given by network participants. Users will stake tokens to become zone anchors, that will work with radio beacons to return location data to the network. FOAM's Proof of Location protocol will be used to confirm consensus on the location of objects and entities in space and time.

Swarm is building a tokenization platform designed to leverage the benefits of blockchain to make it easier to fund and govern a variety of large real world projects. They hope to make it easier to tokenize real world assets, and make them available as investment opportunities. Swarm is also developing the SRC-20 protocol, which will define a common set of rules that a security token must follow, and will give users the ability to create DApps that follow these accepted properties. Swarm is powered by the SWM token.
