The lightweight zero-knowledge proof will allow Bitcoin users to verify payments without having to download the full blockchain history. StarkWare, a company specializing in zero-knowledge (ZK) technology, a way of verifying information without revealing the specific contents of that information, said it created a ZK verification of the Bitcoin (BTC) blockchain that can run on mobile devices. The proof contains all the Bitcoin block headers from the genesis block until the present, but not the full and detailed Bitcoin blockchain history, which is over 680 gigabytes in size.  Each block header includes the version number of the Bitcoin software used to mine the block, a reference to the previous block in the chain, a timestamp, the block size and the nonce — the random number the miner has to find to add the block to the ledger.

StarkWare’s new Stark Two (S-two) prover lets users generate cryptographic proofs directly on their devices. Blockchain company StarkWare has unveiled zero-knowledge (ZK) prover STARK Two (S-two), enabling enhanced privacy and verification on everyday devices like phones, laptops and browsers.  The company said the new ZK prover allows users to generate complex cryptographic proofs from the client side. This means users can generate ZK-proofs directly on their devices instead of relying on a server or cloud infrastructure, opening the door for faster and more private applications across the internet.  “S-two will bring STARK proving to everyday devices, and open the door for new real-world proving use cases,” said Eli Ben-Sasson, StarkWare co-founder and CEO, adding that the tool could empower the next wave of ZK applications.  Read more
