The POL Upgrade on Polygon Network: Everything You Need to Know

The blockchain ecosystem is continually evolving, with platforms often updating their frameworks to offer better scalability, security, and interoperability. One such significant development that has garnered a lot of attention lately is the POL upgrade on the Polygon (formerly known as Matic) network. If you’re a developer, investor, or a cryptocurrency enthusiast, this article aims to give you a comprehensive look into what the POL upgrade entails.

Purpose of the POL Upgrade

The POL upgrade is a key milestone in the Polygon 2.0 roadmap. The primary objective behind this upgrade is twofold: to improve the scalability of the Polygon network and to enable the validation of multiple chains within the Polygon ecosystem. The idea is to create a more robust and versatile environment for decentralized applications (dApps), thereby attracting more developers and users to the platform.

Polygon’s founder Sandeep Nailwal summarizes it like this:

  • Gen 1 (BTC): Holders watch from the sidelines.
  • Gen 2 (ETH): Holders help secure things.
  • Gen 3 (POL): Holders do it all, across multiple networks.

Token Upgrade: From MATIC to POL

It’s essential to clarify that POL is not a new cryptocurrency but an upgraded and rebranded version of the existing MATIC token. The upgrade aims to augment the token’s utility and functionality, positioning it as a more potent tool for developers and users within the Polygon network. Such enhancements often translate into better liquidity, governance capabilities, and broader utility in decentralized finance (DeFi) applications, among other things.

Proposal and Approval Process

The proposal for the POL upgrade was introduced by a consortium of Polygon’s founders, developers, and research team. It wasn’t a decision made overnight; instead, it was a well-thought-out move involving substantial technical assessment and community feedback. Although the proposal has been put forward by the team, its ultimate implementation is subject to approval from the broader Polygon community. In decentralized systems, it’s standard for significant changes to require a consensus from the network’s participants, typically through a voting mechanism.

Technical Details: In Simple Terms

Polygon is planning to launch a new and improved version called Polygon 2.0. This upgrade is designed to make the blockchain faster, more user-friendly, and capable of handling more transactions. They want to make it as easy to use as the Internet but for transferring value like money, assets, or property.

How Does It Work?

Polygon 2.0 is built on four main parts, each doing a specific job:

  1. Making it Fair and Secure (Staking Layer):
    • This part uses a method called “Proof-of-Stake” to make sure the network is fair and secure.
    • It uses smart contracts, which are self-executing contracts with the terms directly written into code, to manage who can validate transactions.
    • It even has rules for punishing bad actors who try to cheat the system.
  2. Easy Communication Between Different Blockchains (Interop Layer):
    • This part makes it easy to send and receive assets between different blockchains.
    • It uses something called “Message Queues” to handle these transfers.
    • It even has a special component called the “Aggregator” that speeds up these transfers and makes them more efficient.
  3. Processing Transactions (Execution Layer):
    • This part is responsible for collecting and processing transactions.
    • It uses existing technologies to make this process fast and efficient.
    • It has several components like P2P for communication, a Mempool for collecting transactions, and a Database for storing transaction history.
  4. Making Sure Everything is Correct (Proving Layer):
    • This part uses advanced math called “Zero-Knowledge Proofs” to make sure all transactions are valid.
    • It has a “Common prover” that is super-efficient in checking the validity of transactions.
    • It can even handle different types of transaction formats, making it very flexible.

Why is This Important?

Polygon believes that this new structure will be the foundation for all their future projects. They think it will solve many of the current problems in blockchain technology, like slow speeds and complicated user experiences.

Impact on MATIC Token Holders

If you currently hold MATIC tokens, the POL upgrade means that these will eventually be replaced by POL tokens. While the specific procedures for the token swap or migration are yet to be disclosed, it’s generally a straightforward process. For starters, MATIC can be exchanged for POL 1:1 once the new token goes live. Polygon will likely allow a four year grace period for holders to exchange their MATIC. Token holders may need to move their MATIC tokens to a supported wallet or participate in an automated migration process. Details for the same are expected to be released by the Polygon team closer to the upgrade date.

How to Stay Informed

For the most accurate and current information, it is advisable to follow official announcements and resources from the Polygon team. This can include their official blog, social media channels, and community forums.


The POL upgrade promises to be a significant leap forward in Polygon’s journey, setting the stage for more scalable and feature-rich decentralized applications. While much about the upgrade remains under wraps, what we do know suggests an ambitious step forward for one of the most promising Layer 2 solutions in the blockchain space. As the ecosystem awaits the upgrade, it will be interesting to see how the changes will influence Polygon’s position in the increasingly competitive world of layer two blockchain solutions.
