Optionally, if at least one of the accounting node 12 and the accounting node 15 sends a broadcast message in the blockchain network to indicate that there is a miss in the transaction record in the block, the transaction record in the block is checked out, and the block is not recorded in the blockchain ledger.
Optionally, in other embodiments, the accounting node for accounting the transaction records in the block generated by the accounting node 11 is not limited to the accounting node 12 and the accounting node 15, and there may be a plurality of accounting nodes for accounting the transaction records in the block generated by the accounting node 11, and assuming that a certain threshold percentage, for example, 50% of the accounting nodes in the plurality of accounting nodes all send broadcast messages in the blockchain network to indicate that there is a miss in the transaction record in the block, the accounting node does not account the transaction record in the block, and the block is not recorded in the blockchain ledger.
In this embodiment, assuming that the accounting node 12 and the accounting node 15 check the transaction records in the block generated by the accounting node 11, the accounting node 12 or the accounting node 15 may further detect whether the timestamp included in the block is within a preset time period, for example, Tn-1Time to TnWithin a preset time range after the time period corresponding to the moment, the preset time range is, for example, from TnTime to Tn+1The range of time instants. If the time stamp included in the block is from TnTime to Tn+1If the time is out of the range, the block is an invalid block, and the block is not recorded in the block chain account book.
In addition, if the accounting node 11 broadcasts the hash value signed by the timestamp server with the private key and time-stamped by the timestamp server together with the block generated by the accounting node 11 into the blockchain network, when the accounting node 12 and the accounting node 15 receive the broadcast message of the accounting node 11, the accounting node 12 and the accounting node 15 may also query and acquire the public key of the timestamp server from the locally stored blockchain account book, verify the signature of the timestamp server according to the public key of the timestamp server, and if the verification is passed, the accounting node 12 and the accounting node 15 determine that the timestamp is authentic and valid.

In this embodiment, the accounting node 12 and the accounting node 15 are not limited to receive the hash value signed by the timestamp server and time-stamped by the timestamp server and sent by the accounting node 11, and the chunk generated by the accounting node 11, and the accounting node 12 and the accounting node 15 may also receive the hash value signed by the timestamp server and time-stamped by the timestamp server and the chunk generated by the other accounting node, sent by the other accounting node and signed by the timestamp server and the private key. When the hash value corresponding to the block sent by the accounting node 11 is minimum, the accounting node 12 and the accounting node 15 determine that the block generated by the accounting node 11 is a valid block.
Or, the checking node detects whether the hash value corresponding to the block meets a preset condition, including: the accounting node detects whether the hash value corresponding to the block is the maximum value in the hash values corresponding to the blocks sent by the other accounting nodes; if the hash value corresponding to the block meets a preset condition, the accounting node determines that the block is a valid block, including: and if the hash value corresponding to the block is the maximum value in the hash values corresponding to the blocks respectively sent by a plurality of other accounting nodes, the accounting node determines that the block is a valid block.
For example, in this embodiment, the accounting node 12 and the accounting node 15 are not limited to receive the hash value signed by the timestamp server and time-stamped by the timestamp server and the chunk generated by the accounting node 11, which are sent by the accounting node 11 and signed by the timestamp server through a private key, and the accounting node 12 and the accounting node 15 may also receive the hash value signed by the timestamp server and time-stamped by the timestamp server and the chunk generated by the other accounting node, which are sent by the other accounting node and time-stamped by the timestamp server and signed by the private key. When the hash value corresponding to the block sent by the accounting node 11 is the maximum, the accounting node 12 and the accounting node 15 determine that the block generated by the accounting node 11 is a valid block.
In other embodiments, the preset condition that the hash value corresponding to the block sent by the accounting node 11 satisfies is not limited to maximum or minimum.
Optionally, the block sent by the accounting node 11 is approved by the whole blockchain network, and the block sent by the accounting node 11 includes the accounting reward information applied by the accounting node 11, so that when the block sent by the accounting node 11 is effectively recorded in the blockchain account book, the accounting node 11 successfully obtains the mining reward of the blockchain network. All accounting nodes then resume contending for accounting rights for the next block.
In addition, in this embodiment, in order to avoid the accounting node applying for a large number of accounts to rob the Hash value, all nodes in the blockchain network may register in a real-name system.
In the embodiment of the invention, the accounting node carries the hash value corresponding to the block and the timestamp corresponding to the hash value when sending the block, other accounting nodes in the block chain network need to verify the hash value and the timestamp corresponding to the hash value when verifying the block, and the block sent by the accounting node is an effective block only if the hash value meets the preset condition and the timestamp corresponding to the hash value is true, so that the block forged by the accounting node is difficult to pass the verification of other accounting nodes, the accounting node is prevented from passing the forged block to improve the probability of successful accounting right competition, and the fairness of different accounting nodes in accounting right competition is ensured.
