Bitcoin Core 28.1 =link=

Bitcoin Core 28.1 represents a significant maintenance and feature release in the Bitcoin protocol’s reference implementation. Building on the foundational changes of version 28.0, this point release introduces critical bug fixes, performance optimizations, memory pool (mempool) policy improvements, and enhanced peer-to-peer (P2P) protocol robustness. This paper provides a deep dive into the architecture of Bitcoin Core 28.1, analyzing its transaction relay mechanism, validation logic, fee estimation improvements, and security patches. We also examine the release’s impact on node operators, miners, and wallet users, as well as its alignment with long-term Bitcoin scalability and decentralization goals.
