Information processing device that processes write request and transmission control method
A transmission control method includes: generating a write request for writing, to a blockchain, a transaction corresponding to a deal to be recorded in the blockchain; acquiring, from a node that performs a process for writing the transaction to the blockchain, load information that indicates an amount of load pertaining to the process to be performed by the node to write the transaction to the blockchain; and transmitting the write request to the node when a period during which the amount of the load indicated by the load information is less than a threshold reaches a specified time.
1. A non-transitory computer-readable recording medium having stored therein a communication program for causing a processor to perform a process comprising:
generating a write request for writing, to a blockchain, a transaction corresponding to a deal to be recorded in the blockchain;
acquiring, from a node that performs a process for writing the transaction to the blockchain, load information that indicates an amount of load pertaining to the process to be performed by the node to write the transaction to the blockchain; and
transmitting the write request to the node when a period during which the amount of the load indicated by the load information is less than a threshold reaches a specified time.
2. The non-transitory computer-readable recording medium according to claim 1 , wherein
the load information indicates a number of uncommitted transactions for which the node has not yet complemented the process for writing to the blockchain, and
the process further includes transmitting the write request to the node when a period during which the number of uncommitted transactions indicated by the load information is less than the threshold reaches the specified time.
3. The non-transitory computer-readable recording medium according to claim 2 , wherein
the threshold is determined according to a relationship between the number of uncommitted transactions in the node and a probability of failure in the writing of transactions to the blockchain.
4. The non-transitory computer-readable recording medium according to claim 2 , wherein
the threshold is determined according to a relationship between the number of uncommitted transactions in the node and a time needed to write transactions to the blockchain.
5. The non-transitory computer-readable recording medium according to claim 2 , the process further comprising:
activating, when the write request is generated, a counter for which a specified waiting time is set;
stopping the counter in a period during which the number of uncommitted transactions is larger than or equal to the threshold;
decrementing the counter in a period during which the number of uncommitted transactions is smaller than the threshold; and
transmitting the write request to the node when a count value of the counter reaches zero.
6. An information processing device comprising:
a hardware processor configured to
generate a write request for writing, to a blockchain, a transaction corresponding to a deal to be recorded in the blockchain;
acquire, from a node that performs a process for writing the transaction to the blockchain, load information indicating an amount of load pertaining to the process to be performed by the node to write the transaction to the blockchain; and
transmit the write request to the node when a period during which the amount of load indicated by the load information is less than a threshold reaches a specified time.
7. The information processing device according to claim 6 , wherein
the processor decides whether write requests have been congested in the node according to a comparison between the amount of load indicated by the load information and the threshold,
the processor sets a specified waiting time in a counter, decrements the counter when the processor decides that write requests have been congested in the node, and generates a transmission instruction when a count value of the counter reaches zero, and
the processor transmits the generated write request to the node when the counter circuit generates the transmission instruction.
8. A transmission control method comprising:
generating a write request for writing, to a blockchain, a transaction corresponding to a deal to be recorded in the blockchain;
acquiring, from a node that performs a process for writing the transaction to the blockchain, load information that indicates an amount of load pertaining to the process to be performed by the node to write the transaction to the blockchain; and
transmitting the write request to the node when a period during which the amount of the load indicated by the load information is less than a threshold reaches a specified time.
