Transaction consensus processing method and apparatus for blockchain and electronic device

An apparatus for a blockchain network, the blockchain network including a plurality of nodes, the apparatus comprising:

• a receiving module, configured to receive a first data fragment of transaction data that is sent by a target node of the plurality of nodes in a unicast mode, data fragments of the transaction data sent by the target node to different nodes of the plurality of nodes in the unicast mode being different;
• a sending module, configured to broadcast the first data fragment to nodes of the plurality of nodes, and to receive a second data fragment of the transaction data that is broadcast by a node of the plurality of nodes;
• a determining module, configured to determine whether a number of received data fragments of the transaction data reaches an erasure code recovery threshold;
• and
• a recovery module, configured to, in response to it is determined that the number of received data fragments of the transaction data reaches the erasure code recovery threshold, perform data recovery on the received data fragment based on an erasure code reconstruction algorithm to generate the transaction data to be used as a basis for a consensus processing of the blockchain network.

An electronic device, comprising:

• a processor;
• and
• a memory, storing machine-executable instructions, wherein by reading and executing the machine-executable instructions stored in the memory and corresponding to control logic of transaction consensus processing for a blockchain network, the processor is configured to:
• receive a first data fragment of compressed transaction data that is sent by a target node of the blockchain network in a unicast mode, wherein the compressed transaction data is compressed based on a compression algorithm, the first data fragment is one of a number of data fragments of the compressed transaction data obtained based on an erasure code algorithm, and data fragments of the compressed transaction data sent by the target node to different nodes of the blockchain network in the unicast mode are different;
• broadcast the first data fragment to nodes in the blockchain network;
• receive a second data fragment of the compressed transaction data that is broadcast by a second node of the blockchain network;
• determine whether a number of received data fragments of the compressed transaction data reaches an erasure code recovery threshold;
• and
• in response to determining that the number of received data fragments of the compressed transaction data reaches the erasure code recovery threshold, perform data recovery on the received data fragment based on an erasure code reconstruction algorithm to obtain the compressed transaction data, perform decompression processing on the compressed transaction data based on a decompression algorithm corresponding to the compression algorithm to obtain original content of the transaction data, and conduct consensus processing on the obtained original content of the transaction data.
