币界网报道：Polygon has unveiled Heimdall v2 on its testnet, marking a significant upgrade to its proof-of-stake (PoS) network ahead of the mainnet launch. The new version introduces enhanced security and efficiency, including a revamped validator selection process and improved block finality mechanisms. According to Polygon's development team, Heimdall v2 reduces the risk of chain splits and optimizes network performance by streamlining block production and validation. The upgrade is part of Polygon's broader roadmap to scale Ethereum-compatible infrastructure, with the mainnet deployment expected in the coming weeks. Analysts speculate that the POL token could see price appreciation as the upgrade progresses, given its role in staking and network security. Polygon's PoS chain currently secures over $1 billion in total value locked (TVL) and processes millions of transactions daily. The team emphasized that Heimdall v2 lays the groundwork for future interoperability with Polygon's zkEVM and other Layer 2 solutions. Crypto community members are closely monitoring the testnet performance for potential impacts on transaction fees and validator incentives. The upgrade follows Polygon's recent partnerships with major enterprises, including Starbucks and Reddit, leveraging its scalable blockchain solutions.
