Embodiment 1

[0036] refer to Figure 1a As shown, it is a schematic diagram of the steps of a method for verifying the signature of transactions in the blockchain provided by the embodiment of this specification. It should be understood that this method is applied to a device for verifying the signature of transactions in the blockchain. Specifically, the verification The signature device may be a software module capable of performing the following methods and having corresponding functions, or the signature verification device may be a blockchain node capable of performing the following methods and having corresponding functions.

[0037] The signature verification method may include the following steps:

[0038] Step 102: After receiving the target transaction, according to the transaction hash of the target transaction, check whether there is a signature verification result that matches the target transaction cached in the buffer pool, wherein the signature verification result cached in ...

Embodiment 2

[0057] refer to figure 2 As shown, the device for verifying the signature of transactions in the blockchain provided by the embodiment of this specification, the device 200 may include: a search module 202, an end module 204, and a signature verification module 206; wherein,

[0058] The search module 202, after receiving the target transaction, searches whether there is a signature verification result that matches the target transaction cached in the cache pool according to the transaction hash of the target transaction, wherein the signature verification result cached in the cache pool is Cache in the key-value pair KV storage mode, the keyword of each signature verification result is the transaction hash, and the value is the signature verification result;

[0059] End module 204, if a signature verification result matching the target transaction is found, skip this signature verification operation;

[0060] Signature verification module 206, if no signature verification ...

Embodiment 3

[0071] image 3 It is a schematic structural diagram of an electronic device according to an embodiment of this specification. Please refer to image 3 , at the hardware level, the electronic device includes a processor, and optionally also includes an internal bus, a network interface, and a memory. Wherein, the memory may include a memory, such as a high-speed random-access memory (Random-Access Memory, RAM), and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory. Of course, the electronic device may also include hardware required by other services.

[0072] The processor, the network interface and the memory can be connected to each other through an internal bus, which can be an ISA (Industry Standard Architecture, industry standard architecture) bus, a PCI (Peripheral Component Interconnect, peripheral component interconnection standard) bus or an EISA (Extended Industry StandardArchitecture, extended industry standard archite...

Abstract

One or more embodiments of the present specification disclose a method and a device for verifying a signature of a transaction in blockchain, and electronic equipment. The method comprises the following steps: when signature verification is performed on a target transaction, not directly performing the signature verification processing on the target transaction; but based on a transaction hash of the target transaction, searching whether a signature verification result stored corresponding to the transaction Hash of the target transaction is cached in a cache pool or not; if the signature verification result is found, not carrying out signature verification again, and directly carrying out subsequent operations by using the signature verification result; if the signature verification result is not found, carrying out a signature verification operation on the target transaction, and caching a signature verification result in the cache pool. Therefore, through a mode of caching signature verification results in the cache pool, unnecessarily repeated signature verification of target transactions is avoided, and processing resources are reasonably saved.

Description

technical field [0001] This document relates to the technical field of blockchain, and in particular to a method, device and electronic equipment for verifying signatures of transactions in blockchain. Background technique [0002] Blockchain is a decentralized and innovative solution that uses distributed ledger technology to solve multi-party trust problems, and is a cutting-edge technology in the current society. [0003] When the blockchain node processes the transaction normally, it needs to verify the necessary signature of the transaction to ensure the normal execution of the transaction. At present, the transactions that need to be verified come from the following sources: transactions sent directly to blockchain nodes through Remote Procedure Call (RPC) interfaces, transactions forwarded by other blockchain nodes, and transactions contained in consensus blocks trade. [0004] For these three types of transactions, the transaction signature needs to be verified, bu...
