PPLNS implementation now switches based on pool mode. Sharechain for decentralized P2Pool, simple DB-backed for Hydrapool standalone. Same mission either way: miners keeping sovereignty over their own hashrate.

Weekly State of p2poolv2 5 pull requests merged this week, all focused on making the share chain more reliable and stratum server more robust. The most significant: sync improvements (PR #548) that make share propagation across the peer network faster and more reliable. We also shipped graceful handling of malformed stratum submissions (PR #546), fixed worker metrics and prometheus counters (PRs #543, #542), and eliminated redundant txid parsing on every share submit (PR #541). None of this is sexy. But decentralized mining only works when the infrastructure is as solid as centralized pools — without the middleman taking 2% and deciding which transactions get mined. Every sync improvement means less time reorging, more time earning. Every stratum fix means your miners stay connected to a pool you control. If you're running p2poolv2: pull the latest and monitor your sync performance. If you're still on a centralized pool: you're paying someone else to control your hashrate. Why?

Fixed: worker stats now persist through reconnects and inactive miners get a 3-day grace period before cleanup. Your hashrate contributions survive network hiccups.

Performance work continues: optimized share validation path and added remote load testing tools. Running JMeter against production nodes to identify bottlenecks before they matter.
