Polygon’s Proof-of-Stake (PoS) community will bear a significant consensus improve with the rollout of Heimdall v2 on July 10.
Sandeep Nailwal, Polygon’s co-founder, described it as probably the most technically superior onerous fork the chain has undertaken since its launch in 2020.
Following the announcement, the community’s native token, POL, gained practically 10% inside 24 hours, climbing to its highest degree in a month at round $0.20.
Polygon’s Heimdall replace
Heimdall v2 replaces the unique Heimdall shopper, modernizing Polygon’s validator administration system and enhancing how the community syncs states between Ethereum and Polygon PoS.
This can be a important shift from the legacy Tendermint + CosmosSDK setup to the newer CometBFT + CosmosSDK structure.
The upcoming migration follows profitable testing on the Amoy testnet on June 24. Nailwal acknowledged that the improve clears out the technical debt from Heimdall’s earlier construct, initially primarily based on frameworks from 2018 and 2019.
With Heimdall v2, Polygon expects main efficiency positive aspects. Finality time is ready to drop from 90 seconds to simply 4–6 seconds. Block occasions may even shrink from roughly 5–6 seconds to round 2 seconds, paving the way in which for a a lot smoother consumer expertise.
Nailwal mentioned the improve will unlock quicker checkpoints and enhance bridging safety whereas laying the groundwork for future enhancements.
He additionally warned of a doable three-hour delay in checkpoint finality in the course of the migration interval. He additionally urged decentralized functions to extend affirmation thresholds to 256 blocks for the day, as uncommon chain reorganizations may nonetheless happen.
The transition will carry over software knowledge, balances, accounts, provide metrics, and previous milestones.
Nevertheless, Heimdall v2 will launch with a brand new chain ID and its personal genesis block, primarily based on the ultimate state of Heimdall v1. Blockchain historical past is not going to be transferred in the course of the improve.
Bhilai hardfork
This impending improve builds on the Ethereum layer-2 community’s latest Bhilai hardfork, which helped the community obtain the 1,000 transactions per second milestone.
Talking on this replace, Nailwal mentioned:
“This hardfork accelerates capability, permitting cash stream on Polygon to maneuver even quicker, and assist the following wave of onchain funds and RWAs. It additionally permits important enchancment for account abstraction by way of Ethereum’s Pectra improve, EIP-7702.”
