Software architecture for efficient blockchain transactions

The present disclosure provides techniques for efficiently processing blockchain transactions. In one implementation, a computer system broadcasts a first transaction to a blockchain network for addition to a block in a blockchain. The computer system may broadcast a second transaction to the blockchain network for addition to a block in the blockchain, where the second transaction is derived from the first transaction and includes a footprint. The computer system monitors and determines that the first transaction has not been confirmed to a block in the blockchain for a period of time (e.g., a card trapped in a storage pool). In response to determining that the first transaction is stuck, the computer system may transmit a request to replace the footprint with a sufficiently high transaction fee, causing the first transaction and the second transaction to be confirmed to a block in the blockchain, thus causing the first transaction to unstuck. 本公开内容提供了用于高效处理区块链交易的技术。在一种实施方式中，计算机系统将第一交易广播至区块链网络以用于添加到区块链中的区块。计
