The Polygon PoS network is set to launch the Heimdall v2 upgrade on July 10, drastically reducing finality from 90 seconds to just 5 seconds. This major technical overhaul promises faster checkpoints, safer bridging, and an enhanced user experience. Polygon CEO Sandeep Nailwal calls it the most complex hard fork since the mainnet’s 2020 launch.

  • Finality time drops from 90 seconds to ~5 seconds, block time from 5-6s to ~2s
  • Migration requires node operators to have 20GB RAM + 2x Heimdall disk space
  • POL token surged 7% post-announcement, with May transactions hitting 81M (+20% MoM)
