Chain Key Technology

    DFINITY’s chain key technology is a 48-byte public chain key that allows DFINITY’s Internet Computer to finalize transactions. The mechanism is used to remove old blocks from the system and allows the Internet Computer Protocol to operate at web speed by completing transactions required to update smart contract states in 1 to 2 seconds. Chain key technology is also responsible for the communication of various components within the Internet Computer (such as subnets, canisters, and the Network Nervous System (NNS)) and the network’s consensus mechanism.
