On Thursday, Polygon is set to deploy its most technically complex hard fork to date, introducing Heimdall 2.0, an upgrade to its proof-of-stake blockchain. Polygon Foundation CEO Sandeep Nailwal stressed that it replaces legacy infrastructure developed since 2018 and enhances network finality, user experience, and upgradeability.
The new consensus layer aims to finalize blocks in under five seconds and significantly minimize chain reorganizations to just two blocks. This operates to bolster network stability and bridge security.
Nailwal stated, “This … PoS has seen since its 2020 launch,” explaining that Heimdall 2.0 facilitates faster checkpoints and allocates headroom for future iterations.
Operators running legacy nodes are urged to prepare instantly. The upgrade, scheduled for approximately 30 minutes, requires testing and threshold implementation. Node operators were advised “test early, spread the word, and ping us if you hit snags,” Nailwal noted.
However, Heimdall’s finality during the transition period – potentially lasting for hours – is expected to “pause or slow down” temporarily, requiring user caution during this window.
The hard fork arrives shortly after Sandeep Nailwal assumed the role of CEO, centralizing executive control following a shift in the foundation’s governance structure.
