We have collected the transactions in the Bitcoin memory pool from about 17:00 on April 19, 2021 to 21:00 on April 23, 2021 by configuring the Bitcoin full node. This is because the price of bitcoin was high during this period, and frequent transactions caused congestion in the memory pool. The time dependence of Bitcoin transactions is not easy to express in the data on the blockchain. Affected by P2P network conditions, some transactions may not be accessed owing to block broadcasting, but we still obtained and analyzed 244,343 transaction data samples in the memory pool. Each data includes transaction hash, transaction handling fee, transaction size, transaction initiation time, blockchain height at the time of transaction initiation, transaction hash list dependent on the exchange, number of ancestor and descendant transactions in the transaction pool, transaction version number, transaction lock time, transaction input information, and transaction output information.
