Polygon has announced that its most technically challenging upgrade to date, the Heimdall v.2.0 hard fork, will launch on July 10. The consensus layer is transitioning from Tendermint + Cosmos-SDK v.0.37 to CometBFT + Cosmos-SDK v.0.50. This reduces finality to ~5 seconds with no reorgs beyond two blocks, paving the way for faster checkpoints, smoother user experience, safer bridging, and future scalability. During the migration window, a ~3-hour finality lag is expected, and while unlikely, validators are advised to increase confirmation thresholds to 256 blocks.

Event date: July 10, 2025 UTC

What is a hardfork?

The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, changes are periodically introduced into it. A hard fork represents changes that are not compatible with previous versions of software supporting the cryptocurrency network. In order to continue to mine the cryptocurrency, miners need to update the software.

In some cases, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash and EthereumPoW.
