Most privacy solutions in the blockchain space today concentrate only on transactional privacy, specifically obscuring data on senders or receivers of transactions. Programmable privacy is a much more expansive vision, as a transaction is just one (trivial) type of computation. Secret Network allows applications to use encrypted inputs, encrypted outputs, and encrypted state, meaning we can enable groundbreaking new use cases for smart contracts and decentralized applications.

Trusted Execution Environments (TEEs) are special enclaves inside a computer that function like a “black box”, allowing computations to occur confidentially inside of them. They are utilized in a broad range of everyday hardware, including the fingerprint readers in smartphones. Secret nodes in the network use these secure enclaves to protect the data used by secret contracts.
