Polygon Launches Heimdall v2 on Testnet — Will POL Surge Before Mainnet?

• The Polygon Foundation launched the Heimdall v2 upgrade, which includes switching to Base64 encoding and adopting CometBFT for consensus.
• The network aims to reach 1,000 TPS by July 2025 and over 5,000 TPS by October 2025.

The Polygon Foundation has announced a major upgrade to its Proof of Stake ecosystem by releasing the Heimdall upgrade on the Amoy Testnet. The Polygon Heimdall v2 is a revamped consensus client aimed at boosting the performance of its Proof-of-Stake (PoS) network.

Key upgrades include a switch from Hex to Base64 encoding and the adoption of CometBFT for consensus, resulting in a dramatic reduction in transaction confirmation times, from 90 seconds to just 5 seconds.

The Heimdall v2 is a modernized consensus client that is at the core of the Polygon PoS ecosystem and brings major upgrades to the network’s functionality. Like its predecessor, Heimdall v2 manages validators, selects block producers, facilitates spans, orchestrates state synchronization between Ethereum and Polygon PoS, and oversees other critical network operations.

To power its consensus, the upgraded client leverages a fork of the Cosmos SDK (v0.50.13) and CometBFT (v0.38.17). It also ensures a robust and efficient framework for the Polygon ecosystem. This breakthrough significantly enhances the network’s capacity to support real-time payment solutions and cryptocurrency transactions, making it a strong contender in the emerging field of crypto banking.

By enabling near-instant transaction settlements, Polygon positions itself as a leader in facilitating seamless and efficient digital payment systems.

Will Polygon (POL) Price Recover Following Heimdall Launch?

Polygon’s native crypto, POL, has been facing sideways movement over the past month, despite other altcoins showing strength and recovery. Over the past month, the POL price has tanked 24% after facing a strong rejection at $0.24. As of now, the POL price is trading at $0.175, with its daily trading volume dropping under $100 million.

However, the blockchain has some major plans ahead by achieving a strong TPS milestone. In June, Polygon revealed its bold strategy to scale its network to an unprecedented 100,000 transactions per second (TPS), setting the stage for a transformative leap in on-chain global financial transactions, as highlighted in our previous post.

The roadmap outlines key milestones:

• July 2025 Target: Achieve 1,000 TPS, reduce transaction finality to five seconds, and stabilize gas fees. This upgrade is already live on the testnet and marks the first significant step toward Polygon’s scalability goals.
• October 2025 Goal: Scale beyond 5,000 TPS with the integration of AggLayer, enabling seamless cross-chain liquidity. This phase introduces one-second block times, eliminates reorganizations, and ensures instant finality in a devnet environment.

Polygon’s phased approach aims to position the network as a leader in facilitating ultra-fast, efficient, and reliable blockchain transactions worldwide.
