Embodiment Construction

[0027] 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.

[0028] Firstly, the centralized block-chain ledger involved in the embodiment of this specification will be described. In the centralized database service provider, the blockchain ledger is generated in the following way, such as figure 1 as shown, figure 1 A schematic flow diagram of generating a block-chain account book provided by the embodiment of this specification, including:

Abstract

The invention discloses a digital signature method, device and equipment in a block chain type account book. The signature mode of the account book is written when the block chain type account book iscreated, or the signature mode of the account book is specified in the configuration file, so that the database server can acquire the parameter value of the account book for indicating the digital signature type parameter whenever the data block in the account book reaches the signature anchor point; and then information and a signature party required by signature is determined, the signature party is enabled to perform digital signature, and a corresponding digital signature is returned.

Description

technical field [0001] The embodiment of this specification relates to the field of information technology, and in particular to a digital signature method, device and equipment in a block-chain ledger. Background technique [0002] When storing data in a centralized blockchain ledger, users, platforms or other independent third parties are often required to digitally sign the ledger. There are many types of digital signatures, and signing the ledger also consumes more system resources. In practical applications, depending on actual scenarios, users may not need all types of digital signatures. For example, when the ledger is only the user's personal ledger, the user's own signature is not required. [0003] Based on this, a more flexible digital signature scheme in blockchain ledger is needed. Contents of the invention [0004] The purpose of the embodiment of the present application is to provide a more flexible digital signature scheme in the blockchain ledger. [00...
