What is BlockQuick(TM)?
Developed by the Diode team, BlockQuick is the first super light client protocol for Ethereum that addresses the issue of man-in-the-middle attacks and eclipse attacks. It is capable of preventing attacks because it doesn’t depend solely on choosing the longest chain with the highest difficulty on the Proof-of-Work (PoW) network when validating a block. Instead, it validates a block based on the "Consensus Reputation Table."
BlockQuick allows devices and application to directly interact with public blockchain networks. Unlike the current full sync, fast sync, or light sync requirements (i.e. a full sync typically requires more than 200GB of disk storage), through BlockQuick the device only needs a handshake size of 20KB to establish the most recent block hash. The design enables a client to sync up to a recent block with a consensus reputation table.
