Definitions
- the present invention relates to the field of blockchain technology, and in particular, to a method, device and system for implementing blockchain cross-chain communication.
- a blockchain in a narrow sense is a chained data structure in which data blocks are sequentially connected in a chronological order, and cryptographically guaranteed non-tamperable and unforgeable distributed ledgers.
- Blockchain in a broad sense refers to the use of blockchain data structures to verify and store data, the use of distributed node consensus algorithms to generate and update data, the use of cryptography to ensure the security of data transmission and access, and the use of automated script code.

- the distributed ledger That is, transaction accounting is done by multiple nodes distributed in different places, and each node records the complete account, so they can all participate in supervising the legality of the transaction, and can also jointly testify for it. Unlike traditional centralized accounting schemes, no single node can record accounts separately, thus avoiding the possibility of a single biller being controlled or being bribed to account for false accounts. On the other hand, since there are enough billing nodes, in theory, unless all the nodes are destroyed, the accounts will not be lost, thus ensuring the security of the account data.
- the transaction information stored on the blockchain is public, but the account identity information is highly encrypted and can only be accessed if authorized by the data owner, thereby ensuring data security and personal privacy.

- FIG. 2 is a schematic flow chart of a proxy rights Byzantine fault tolerance algorithm according to an embodiment of the present invention.
- the proxy-based Byzantine Fault Tolerance Algorithm (DS-PBFT) of the link in this embodiment is similar in flow to the flow of the PBFT algorithm.
- DS-PBFT Byzantine Fault Tolerance Algorithm
- the link is verified by the Byzantine fault-tolerant algorithm using the proxy rights to the transaction received from the sub-link (ie the first transaction).
- the design idea is as follows:
- the Workload Proof Algorithm is a Byzantine Fault Tolerant (BFT) consensus algorithm that is applied to Bitcoin and Ethereum. Since the release of Bitcoin, the workload proof algorithm has proved its reliability, but its waste of resources is also obvious to all.
- the Probability Proof Algorithm is a consensus algorithm proposed to solve the problem of waste of workload proof algorithm resources.
- the voting power is used to replace the power of the miners in the voting equity pool. The punishment mechanism ensures the integrity of the voters.
- computing power cannot be dispersed. A miner with a fixed power cannot mine at the same time and keep the total power. Double, but a voter with a certain interest can vote for every possible block, as long as any block becomes the future winner, it can guarantee that its rights will not be damaged. However, this has great security risks because it greatly reduces the cost of doing evil for the perpetrators.
- Raft as a commonly used efficient consensus algorithm, its biggest drawback is that it can not prevent Byzantine nodes, a Byzantine leader node with a strong network configuration will bring a devastating blow to the Raft algorithm consensus.
- some algorithms combining Raft and BFT were proposed. Taking PBFT (Practical Byzantine Fault Tolerance) as an example, some reliable nodes are called verifiers, and the verifier has the opportunity to become a leader. In each round of blockchain generation, there will be one. The new certifier will default to the leader of the round, and the leader will be responsible for packaging the new block and broadcasting a block that he or she considers reasonable to all certifiers.
- PBFT Practical Byzantine Fault Tolerance
- the common node only synchronizes the new block sent from the leader node and does not participate in the consensus.
- the security of the consensus algorithm depends only on the number of verification nodes. The increase of the number of common nodes cannot be improved. Byzantine fault-tolerant security.
- the participation of non-verified nodes has increased in the new consensus mechanism.
- a verification node corresponds to a verifier account, and the non-authenticator can earn his own interests by entrusting the entitlement to the verifier and voting by the verifier proxy.
- proxy certifier Because of the relationship of interests, non-verifiers will carefully choose the proxy certifier, thus achieving the defect that all people participate in the consensus without the efficiency reduction caused by all nodes participating in the consensus.
- DS-PBFT proxy rights Byzantine Fault Tolerance Algorithm
- the link is used as a consensus algorithm by using the proxy rights Byzantine fault-tolerance algorithm implemented by the verifier vote, so that all nodes participate in the consensus of the link, and no efficiency is reduced by all nodes participating in the consensus. defect.
- the sub-chain can also use the proxy rights Byzantine fault tolerance algorithm to verify the transaction (ie, the second transaction) received from the link.
- each block in the third blockchain includes a block header portion and a data portion (Data).
- the link is composed of a number of blocks having an increasing number of blocks, each of which may include a number of transactions, which may be arranged in chronological order.
- the block header portion of each block may include the generation time of the block, the location, and verification information when the block is generated.
- the block header portion includes: a Chain ID, a Height, a Time, a World Hash, and a previous one adjacent to the block.
- FIG. 3 is a schematic structural diagram of a block by a link according to an embodiment of the present invention.
- each block in the third block chain may further include a voting part (Last Commit).
- the voting portion can be used to establish a link between the block and the previous block.
- the block consensus requires two rounds of voting that exceed 2/3 of the verification node's equity. All 2/3 verification node votes (Commit) of the second round will be temporarily saved, and will be placed in the voting part of the block (Last Commit) when the next block is proposed.
