Embodiment 1

[0043] Such as figure 1 Shown:

[0044]The present disclosure provides a method for detecting fake anchor nodes in the alliance chain sharding consensus system, including:

[0045] S1: Divide the blockchain network into N regional blocks P i , i=1, 2..., N, where N is an integer greater than 2.

[0046] Preferably, the blockchain network can be divided into N geographical blocks P according to the geographic location i , i=1, 2..., N, wherein N is an integer greater than 2;

[0047] The geographic location area may be:

[0048] The global blockchain network is divided into 4 geographical blocks according to the geographical area: European block, Asian block, American block and other regional blocks.

[0049] S2: Each of the geographical blocks P i The nodes in the vote select the anchor node representing all the nodes of the regional block Pi;

[0050] specifically,

[0051] The supervisory node receives the voting announcement information broadcast by the voting initi...

Embodiment 2

[0089] The present disclosure can also make the following improvements on the technical solution of Embodiment 1:

[0090] The anchor node fraud detection method in the alliance chain sharding consensus system of the present disclosure also includes:

[0091] S5: If the regional block P that initiates the transaction i The anchor node of is an untrusted anchor node, then the regional block P i Re-vote to elect a new node as the representative of the regional block P i anchor node.

[0092] The beneficial effect of above-mentioned technical scheme is:

[0093] If the anchor node of the current regional block to be traded is untrustworthy, a new node will be re-voted as the anchor node representing the regional block to ensure the reliability of the transaction.

Embodiment 3

[0095] Such as image 3 as shown,

[0096] The present disclosure can also provide a device for detecting fake anchor nodes in the alliance chain sharding consensus system, including:

[0097] Blocking module 301, used to divide the blockchain network into N regional blocks P i , i=1, 2..., N, wherein N is an integer greater than 2;

[0098] Preferably, the blockchain network can be divided into N geographical blocks P according to the geographic location i , i=1, 2..., N, wherein N is an integer greater than 2;

[0099] The geographic location area may be:

[0100] The global blockchain network is divided into 4 geographical blocks according to the geographical area: European block, Asian block, American block and other regional blocks.

[0101] Anchor node selection module 302, used for each of the regional blocks P i The nodes in are voted to represent the regional block P i Anchor nodes for all nodes;

[0102] Sending module 303, used when there is a transaction init...

Abstract

The invention relates to the technical field of block chains, and provides an anchor node falsification detection method and device, a medium and equipment, and the method comprises the steps of dividing a block chain network into N regional blocks Pi, i = 1, 2... N, and N is an integer greater than 2; enabling nodes in each regional block Pi to select anchor nodes representing all nodes of the regional block Pi through voting; when a transaction initiator initiates a transaction in the regional block Pi, enabling the anchor node of the regional block Pi to send verification information to theanchor nodes of other regional blocks; and enabling the other regional blocks to vote and verify the verification information of the transaction initiator, so that the result of the vote verificationdetermines whether the anchor node of the regional block Pi of the transaction initiator initiating the transaction is a trusted anchor node. The invention provides an anchor node falsification detection method in a fragmentation consensus system, and the credibility of a transaction initiator is guaranteed. The efficiency of mutual communication between the cross-domain blocks is greatly improved, and the problem that in the prior art, forged data is difficult to identify is solved.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and more specifically, the present disclosure relates to a method, device, medium and equipment for detecting fraudulent anchor nodes. Background technique [0002] In 2008, Satoshi Nakamoto proposed Bitcoin. With the rapid development in recent years, the blockchain, which is the core of its underlying technology, has also come into people's sight. The consensus mechanism as the core of blockchain technology has attracted great attention and widespread attention from government departments, financial institutions, technology companies and capital markets. In the study of related consensus algorithms, Proof of Work (PoW) has become the mainstream idea of ​​P2P electronic currency since the advent of Bitcoin. It ensures the reliability of the entire network information through computing power competition, but there are relatively Serious waste of computing power. Therefore, some digi...
