Gun
GUN is an ecosystem of tools that let you build community run and encrypted applications.
What is Gun?
GUN is a small, easy, and fast protocol for syncing data and encrypting it safely. It works well with both SQL and NoSQL like data, and uses cryptography to secure the data itself, not the servers. It uses the concept of a Public space, User space (where only the owner can write), and a Frozen space (one time write, everyone can read) to ensure decentralization works at a lower level.
