[BIP Draft] P2P UTXO Set Sharing

In a recent discussion on the Bitcoin Development Mailing List, Eric Voskuil highlighted significant performance advantages of Libbitcoin over bitcoind when running on a 16GB Raspberry Pi5. He pointed out that by merely adjusting configuration settings to better suit larger machines, Libbitcoin could achieve superior outcomes. The details of this performance comparison are documented in a status update which can be viewed here.

Despite extensive optimizations and substantial investments in bitcoind over the last 16 years, it still underperforms on both modest and high-end hardware setups. In contrast, the Libbitcoin team, a small group of volunteers, has only begun to scratch the surface of performance tuning and optimization for their system.

The exchange also touched upon skepticism regarding the operational efficacy of Libbitcoin versus bitcoind. Accusations of exaggeration and delusion were mentioned, reflecting a contentious debate within the community. This was particularly evident when a scenario previously dismissed as implausible was indeed realized just 13 days later, further challenging the criticisms aimed at Libbitcoin's supposed inefficiencies and affirming its potential on standard hardware configurations.

Overall, this discourse underscores ongoing tensions and differing perspectives on the optimal approaches to Bitcoin software development, highlighting the complexities involved in evolving such critical digital infrastructure.
