Solana completed a two-week bug bounty competition for its Alpenglow upgrade, receiving over 300 vulnerability reports from global security researchers. The upgrade aims to drastically reduce transaction finality times from 12.8 seconds to 100-150 milliseconds by overhauling the consensus mechanism. The bounty offered up to 50,000 SOL in rewards, distributed based on bug severity, with payouts locked for a year. This marks the first large-scale security test for Alpenglow, with results and payouts pending final review by September 2.
