Bitcoin Core releases v31.0, introducing cluster mempool and enhancing private transaction broadcast

Techub News reports that Bitcoin Core has released version v31.0. The core of this update lies in the introduction of the "cluster mempool" design. This mechanism reorganizes related transactions into clusters not exceeding 64 transactions or 101 KB in size, enabling nodes to more precisely evaluate the overall value of transaction groups based on the fee rate diagram. This optimizes block packaging efficiency and refines the logic for RBF and CPFP. Furthermore, the new version significantly enhances privacy features, supporting users in broadcasting transactions privately via the Tor or I2P networks, effectively hiding the transaction initiator's IP address and geographical location. While ordinary transfer users are less affected, users of the Lightning Network or complex wallet services may notice significant changes in transaction acceptance rules.
