Problems solved by technology

Similarly, it is impossible to conduct security supervision on the nodes that have been elected to participate in the blockchain consensus, and cannot solve the security risks of the consensus nodes that have participated in the blockchain
[0007] To sum up, in the existing technology, the private keys of the nodes participating in the consensus are easily stolen, and the security of the nodes participating in the consensus, as well as the security of the pledged rights and block rewards obtained are internal or to the relevant participants. defenseless state
However, there is no good method in the prior art to solve the above problems

[0077] Such as figure 1 As shown, it is a specific flow chart of a method for solving potential safety hazards of DPOS consensus node rights and interests in the present invention, which includes:

[0078] S1: Receive a request for modifying a node address sent by an account address, and the request includes a newly deployed update node address.

[0079] Specifically, in this embodiment, the block producing node participates in the DPOS consensus in the form of separating the node address and the account address. The node address is only used for block producing operations, and all important content related to the rights and interests of the node is stored in the account address. , kept by the node holders themselves. When it is monitored that the private key corresponding to the node address used for block generation is stolen, a new update node address needs to be redeployed, and a request to modify the node address is sent to the DPOS consensus through the account address, a...

[0113] Such as figure 2 As shown, a structural diagram of a block generating node 1 of the present invention, specifically including a block generating module 11 and an account module 12;

[0114] The block generating module 11 is used to establish and store node addresses, participate in the DPOS consensus through the node addresses, and generate blocks through the node addresses after being selected by the DPOS;

[0115] The account module 12 is used to establish and store an account address, send a request for modifying the node address through the account address, and store the block rewards obtained from producing blocks in the account address.

[0130] The account address verification unit 211 is configured to verify whether the account address is included in the node mapping table after receiving the request sent by the account address to modify the node address, and at the same time apply the The public key of the account address in the consensus to verify the account address;

[0131] The node address modifying unit 212 is configured to find the node address mapped to it in the node mapping table according to the account address after the account address verification is passed, and replace it with the updated node address. The node mapping table The corresponding relationship between the node address and the account address preset in the DPOS consensus, so that when the DPOS consensus sel...

Abstract

The present invention relates to the technical field of DPOS consensus node rights and interests security, and provides a method and system for solving hidden dangers of rights and interests security of DPOS consensus nodes. update the node address; verify the account address of the signature, after the verification is passed, find the node address mapped to it in the node mapping table according to the account address, and replace it with the updated node address, the node mapping table is The corresponding relationship between the node address and the account address preset in the DPOS consensus; the DPOS consensus selects the block producing node, and when the account address is selected by the DPOS consensus, the replaced all The above node address is used to generate blocks. It solves the problem that the private keys of the nodes participating in the consensus are easy to be stolen, and the security of the nodes participating in the consensus, as well as the security of the pledged rights and block rewards obtained are in a state of being internal or undefended to the relevant participants.

Description

technical field [0001] The present invention relates to the technical field of security of rights and interests of DPOS consensus nodes, in particular to a method and system for solving hidden dangers of security of rights and interests of DPOS consensus nodes. Background technique [0002] In the DPOS consensus algorithm, if a node wants to participate in the blockchain consensus and obtain benefits from it, it must pledge its rights and interests as a guarantee to prevent the node from doing evil in the consensus. The more stakes staked by nodes participating in the consensus, the higher the probability of block generation. [0003] At present, many node holders entrust their nodes to specialized organizations for hosting or place them on cloud servers for convenience. Even the physical nodes that operate independently, many of them are institutionalized. For example, the nodes of EOS are all operated by institutions. All of the above situations will bring security issue...
