StarkWare, a leading zero-knowledge (ZK) cryptography firm, has launched a revolutionary mobile verifier that enables Bitcoin transaction verification directly on smartphones. This groundbreaking tool reduces the verification process to under 100 milliseconds by utilizing a compact 1MB proof of the entire Bitcoin ledger from genesis to present day. 2009’s genesis block onwards is included, excluding transaction data, while retaining critical metadata like version, timestamp, previous hash, block size, and nonce. This innovative approach leverages Simplified Payment Verification (SPV) principles, a cornerstone introduced by Satoshi Nakamoto in his whitepaper. This solution empowers users with limited time, resources, or technical expertise to access the Bitcoin network directly, unlocking its potential on their smartphones.
