BOLT eliminates lag time and high transaction fees — while offering strong privacy protections — so you can use Zcash, Bitcoin, Ethereum and other digital currencies for everyday payments and purchases. Your transactions are instant and private — regardless of currency. Blockchain transactions are slow, and the fees are high. BOLT allows users to transact instantly, off-chain, and adds a privacy layer to protect user information. BOLT enables payment channels that hold funds in escrow until one or more parties is ready to cash out. Payments within these channels are off-chain and unlimited, and users remain anonymous. BOLT’s privacy protections rely on zero-knowledge proofs, based on the research of leading scientists and cryptographers.
