Polygon’s Most Complex Hard Fork Goes Live
Polygon is set to deploy its most complex hard fork to date on Thursday, upgrading its proof-of-stake blockchain with a new consensus layer called Heimdall 2.0. In a post on X, Polygon Foundation CEO Sandeep Nailwal described the upgrade as the most technically challenging since the network launched in 2020.
Key Improvements in Heimdall 2.0
The Heimdall 2.0 upgrade enhances Polygon’s proof-of-stake blockchain by replacing outdated components with modern infrastructure. This update will:
- Reduce finality to about five seconds
- Minimize chain reorganizations beyond two blocks
- Improve network stability and bridge security
Preparing for the Upgrade
Sandeep Nailwal advised node operators to prepare for the 30-minute mainnet update. While scripts and documentation are available, users should expect temporary instability during the process as finality may lag by up to three hours.
Leadership Changes at Polygon
This upgrade follows Polygon Foundation’s transition to centralized leadership under co-founder Sandeep Nailwal as CEO. The move aims to strengthen Polygon’s position in the competitive layer-2 blockchain space.
