StarkWare launches lightweight Bitcoin verification for use on mobile devices

The lightweight zero-knowledge proof will allow Bitcoin users to verify payments without having to download the full blockchain history.

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.
