What is the digital signature of the Bitcoin.
The digital signature of bitcoin, which is generated only by the transfer of the bitcoin transfer, is a forgery-proof string. by verifying the number string, one proves that the transaction was initiated by the outbound party and that the transaction information was not changed in transit.
Digital signatures shorten transaction information to fixed-length strings by Digital Digest technology. Give me a chestnut, niu niu. A currency transfer is required to make a digital digest of the transaction, shorten it to a string, and then encrypt the digest with its own private key to form a digital signature. Upon completion, cattle and cattle will need to broadcast the original (transaction information) and digital signature to the miners, miners with cattle, the public key for verification, if the successful verification, that the transaction is really cow and cow, and the information has not been changed.
At the same time, the digital signature encryption of the private key and the decryption public key inconsistent, using asymmetric encryption technology. Looks so complicated, in fact, the transfer only requires you to enter the private key to complete the moment.
