A digital signature is a digital string, which can only be generated by the sender of the information, and others cannot forge it. This number string is also an effective proof of the authenticity of the information sent by the information sender.

In terms of digital signature, HNB is the top in the industry. He used Secp256k 1 elliptic curve, which is the parameter of ECDSA (Elliptic Curve Digital Signature Algorithm) curve used by Bitcoin and defined in the standard of efficient cryptography. HNB's digital algorithm occupies little bandwidth and storage resources, and the length of the key is very short. All users can use the same operation to complete the domain operation. It is these two points that determine that HNB's signature algorithm can help blockchain users to obtain digital currency content more quickly and conveniently.
