Embodiment Construction

[0035] In order for those skilled in the art to better understand the technical solutions in the embodiments of this specification, the technical solutions in the embodiments of this specification will be described in detail below in conjunction with the drawings in the embodiments of this specification. Obviously, the described implementation Examples are only some of the embodiments in this specification, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this specification shall fall within the scope of protection.

[0036] First, the centralized block-chain ledger involved in this specification will be described.

[0037] In the centralized database service provider involved in the embodiment of this specification, a ledger includes multiple data blocks, and the data blocks are pre-generated in the following way:

[0038] Receive the data records to be stored, and determine the hash value of each data record...

Abstract

Disclosed are a signature verification method, system, device and equipment in a block chain ledger. When the user initiates the verification, the verification object parameter specifies the type of verification and gives the relevant hash value, and the server can determine the digital signature that the user wants to verify according to the hash value and the verification object parameter, thereby obtaining The digital signature of the data related to the hash value is given to the user for verification by the user.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular to a signature verification method, system, device and equipment in a block-chain ledger. Background technique [0002] When the centralized database server provides external services with block-chain ledgers, usually there may be multiple users in one ledger. In order to ensure the authenticity of the data in the ledger, digital signatures are generally required for the data exchange in the ledger. In addition, the database server will also generate other relevant signature certificates for the ledger, for example, the timing certificate for some ledgers. Therefore, multiple digital signatures can be involved in one ledger. [0003] There are multiple signatures in the blockchain ledger, and users need to know at any time that the digital signatures of other parties related to them are authentic and credible, but in practice, users do not clear thei...
