Problems solved by technology

However, this method is easy to be stolen because the identity information is stored in the form of a file, so that other malicious people can get the same opportunity to generate blocks, and even replace the blocks issued by real nodes

Abstract

The invention discloses a block sending method and device for a block chain. The block sending method comprises the steps that interaction data on a block chain network is received and packaged into anew block; security hardware signs the new block by using an identity recognition private key packaged inside and adds the signature information to the new block so as to generate a new signature block; and the new signature block is sent to the block chain network. By using the method and device disclosed by the embodiment of the invention, the identity recognition private key packaged inside the security hardware of a block sending node of the block chain cannot be extracted, so that the non-duplication and uniqueness of identity recognition information of the block sending node are ensured, and thus the witch attack performed by the block sending node by using the duplication is avoided; and a receiving node on the block chain can determine the identity of a block sender by verifying the signature information in the new signature block so as to judge whether the block is generated by a license node or not.

Description

technical field [0001] Embodiments of the present invention relate to the fields of blockchain and security hardware, and more specifically, relate to a block generation method and device on the blockchain. Background technique [0002] Blockchain is a decentralized distributed ledger that records every transaction on every node of the blockchain network. Each node includes all blocks, and each block includes several transactions. The set of all blocks contains the set of all transactions on the blockchain, so the generation of blocks is very important. Since the decentralized mechanism of the blockchain allows any node to have the opportunity to generate a block, how to ensure the fairness and justice of each node's block generation opportunity is crucial. [0003] The design of block generation opportunities is the core of the blockchain consensus mechanism. The first thought is to use software to generate blocks, that is, within a certain time interval, each software cli...
