Bitcoin Core has launched version v31.0, introducing significant improvements to Mempool logic. This update allows nodes to better evaluate the collective value of related transactions, influencing decisions on whether to retain, forward, or include them in a block. While standard users will see minimal changes, those using RBF, CPFP, the Lightning Network, or complex wallets may observe differences in transaction handling. Additionally, the update bolsters privacy by enabling sendrawtransaction over Tor/I2P, which helps conceal the sender's IP address and geographic location from recipients. This enhancement is particularly beneficial for users seeking increased anonymity in their transactions.
