Many believe that Polygon 2.0 could significantly change the landscape for decentralized application (DApp) development, opening up DApps to a wider global audience. The latest iteration of the technology is faster, cheaper, and more scalable than ever.
Polygon has dubbed its 2.0 update a "value layer" that offers the democratization of finance, digital ownership, and innovative coordination mechanisms. The value layer provides an internet solution that serves users, not gatekeepers.
It's significantly more scalable than the previous version of the network. This is because it uses zero-knowledge (ZK) technology. ZK-rollups are a type of Layer-2 scaling solution that uses zero-knowledge (ZK) proofs to batch transactions and transfer them off-chain. This allows for significantly higher throughput and lower costs than traditional Layer-1 blockchains.
Polygon 2.0 will use a novel cross-chain coordination protocol to unify all the network chains. This protocol will allow users to seamlessly transfer assets between chains without worrying about liquidity fragmentation or security risks. This experience will be as smooth for users as operating on a single chain.
In this article, we'll explore Polygon's history and provide an overview of Polygon 2.0, ZK technology, and the Polygon 2.0 roadmap.
What is Polygon?
The Polygon Network, initially launched in 2017 as the Matic Network by Jaynti Kanani, Sandeep Nailwal, Anurag Arjun, and Mihailo Bjelic, emerged as a blockchain platform designed to tackle Ethereum's scaling challenges.
During that time, Ethereum struggled to meet the increasing demand for its decentralized applications (DApps), which led to high transaction fees and slow processing times. To address these concerns, the Matic Network implemented a sidechain-based approach for Ethereum scaling, using independent blockchains linked to Ethereum through a bridge.
These sidechains provided a more cost-effective and faster transaction environment than the Ethereum main chain. Additionally, the Matic Network adopted a proof-of-stake (PoS) consensus mechanism to enhance the security of its network.
In 2021, the project was rebranded and transformed into Polygon, expanding its focus beyond sidechains. As a versatile Ethereum scaling platform, Polygon now accommodates various Layer-2 scaling solutions, including optimistic rollups and ZK-rollups.
Polygon has addressed many of Ethereum's scalability issues, resulting in significant growth in recent months. The number of DApps developed on Polygon has surged from 500 to over 7,000, and daily active users have skyrocketed from 10,000 to over 100,000.
With a strong team, vibrant community, and a proven track record, many believe Polygon is well positioned to become the leading Ethereum scaling platform.

When will Polygon 2.0 go live?
If you're a fan of the Polygon Network, you may want to keep track of these important dates, where they plan to provide a series of blog posts, community meet-ups, AMAs with the founders and engineers, and more.
On June 20, 2023, the Polygon Labs engineering team announced a breakthrough by unveiling a proposal to enhance Polygon PoS by implementing ZKEVM validium. This groundbreaking concept establishes a decentralized Layer-2 solution fortified by ZK proofs. The implications of this upgrade are meaningful for the Polygon ecosystem, as it empowers Polygon PoS to achieve heightened security and enhanced performance, and establishes itself as a vital component within the Polygon 2.0 framework.
On June 29, 2023, as promised, the engineering team took a deeper dive into the protocol's vision and architecture.
According to Polygon, the architecture is broken down into four protocol layers:
Staking Layer
The Staking Layer is a protocol based on PoS that uses Polygon's native token to bring decentralization to the participating chains on the Polygon network. It accomplishes this through a widely distributed validator pool and an integrated restaking mechanism.
Interop Layer
The Interop Layer allows for secure and seamless cross-chain communication within the Polygon ecosystem. It simplifies the intricacies of inter-chain messaging and provides users with a cohesive experience, making the entire Polygon network function as a unified chain.
Execution Layer
The Execution Layer empowers any Polygon chain to generate ordered batches of transactions, known as blocks. This layer's protocol is relatively standardized and is employed similarly by various blockchain networks such as Ethereum and Bitcoin.
Proving Layer
The Proving Layer is a flexible, high-performance ZK proving protocol. It generates proofs for all internal and external transactions (including cross-chain transactions) across every Polygon chain.
We'll continue to provide timely updates as additional information becomes available on the roadmap for Polygon 2.0.
The Matic to POL upgrade
According to Polygon, in Q4 2023, the native token on Polygon 2.0 will be switched from MATIC to POL, becoming the primary gas and staking token. This is the opening phase of the upgrade to the Polygon PoS blockchain, and it'll bring about a Staking Layer to provide security for multiple blockchains in the Polygon 2.0 environment.
Polygon Improvement Proposals (PIPs)
Polygon Labs has moved to Polygon 2.0, launching three PIPs. POL tokens will become the gas and staking tokens for the Polygon network, with a 1:1 exchange rate from MATIC tokens. The allocated supply is 10 billion tokens, with a yearly emission of 2%, assigned to the validators' staking rewards and a community treasury.
POL as a hyperproductive token
Polygon Labs sees POL as critical in fulfilling the Polygon 2.0 agenda. This development is predicted to be a technical and commercial update on MATIC to protect, coordinate, and expand the Polygon network. POL is intended to power all Polygon blockchains, and allow individuals to interact with one blockchain.
This transition is meant to tackle the potential restrictions that arise from MATIC's fixed supply, since POL is planned to have an increasing supply to support the ecosystem.
Role of POL in Polygon 2.0
The POL token is a key part of the new Polygon 2.0 design, transforming the PoS chain into a ZKEVM validium Layer-2 network and establishing a supernet design.
Validators can restake their POL tokens to support multiple chains in the Polygon supernet, and gain extra rewards. The original amount of POL tokens is 10 billion, which will be used to switch from MATIC to POL. Any issuance that follows will have a predetermined rate.
AggLayer: bringing blockchains together
Do you remember what the Internet was like in the early 90s? Several isolated networks didn’t work well together (not to mention SLOW dial-up). Early blockchains are similar — they’re like separate islands with their own rules, making it hard to move between them smoothly. Polygon's AggLayer protocol helps to address this.
From monolithic to aggregated
Traditional blockchains tried to do everything in one place (monolithic), but they hit roadblocks with speed and scalability. Think of them as bulky arcade games that can’t keep up with 2024 graphics cards.
To solve this, modular blockchains split tasks across different chains, making them more like a series of connected machines. While this was more flexible, it still felt clunky and fragmented, like trying to connect different computer parts that didn’t fit perfectly.
What makes AggLayer special?
AggLayer merges the simplicity of traditional blockchains with the flexibility of modular ones. It connects different blockchains into a single, smooth network using advanced cryptography. It’s like turning those isolated islands into a well-connected city where moving from one place to another is effortless and quick.
Why use AggLayer?
For developers, AggLayer can be used to create apps that work across multiple blockchains without extra hassle. For users, the app experience is simpler — closer to browsing the web where you don’t need to think about the underlying networks or technical jargon. You can make fast, secure transactions across different blockchains without even noticing the complexity behind it.
How the Type 1 prover transforms EVM into ZK Layer-2
Imagine upgrading your bike to a high-speed electric bike without changing any parts. That's what the new Type 1 prover from Polygon and Toposware does for blockchain technology.
Traditional EVM (Ethereum Virtual Machine) chains are akin to regular bikes — highly useful but limited. They handle transactions at a slower pace and higher cost. The Type 1 prover is the "electric upgrade," allowing these chains to transform into ZK Layer-2 chains. This means they can now connect to Polygon's AggLayer, which brings different chains together into a single network.
This upgrade makes everything faster and cheaper. Transactions, which used to be expensive and slow, are now processed 36 times faster and at a fraction of the cost, as low as $0.002 per transaction. The Type 1 prover is open-source, meaning anyone can use or improve it. It makes existing EVM chains into ZK Layer-2, improving Ethereum's interoperability.
Polygon Chain Development Kit and X Layer
The Polygon Chain Development Kit (CDK) is an open-source framework created to accelerate the execution of ZK-driven Layer-2 blockchains on Ethereum. It's a significant part of the Polygon 2.0 infrastructure designed to increase blockchain scalability and compatibility. The CDK supports a high level of customization, allowing designers to construct Ethereum Layer-2 chains from the ground up or to shift existing Layer-1 chains to Layer-2.
OKX has rolled out X Layer, an Ethereum Layer-2 network constructed using CDK. This network offers enhanced security and scalability while keeping transaction costs low by using ZK proofs.
X Layer seeks to transform Web3 by emphasizing decentralization and building a more transparent, manageable, and inclusive internet. The aim is to make Web3 more widely used, scale Ethereum to accommodate billions of people worldwide, and support the expansion of the crypto and digital asset space.
The uniqueness of X Layer lies in several key aspects:
Integration of OKX and Polygon Ecosystems: This collaboration will improve the user experience and give developers access to advanced technology. OKX and Polygon's builder communities will lead to more innovation, projects, and users for X Layer.
Using the OKX platform's strength: OKX is one of the largest crypto communities with 50 million users.
Ethereum compatibility: X Layer is compatible with Ethereum, so existing EVM smart contracts, developer tools, and wallets can operate on X Layer without code modifications. This allows for easy migration of existing DApps to X Layer.
Cost efficiency: X Layer uses advanced ZKSNARK technology to reduce the size of transactions, making them more cost-effective. This benefits developers and users by giving them a more seamless and enjoyable experience.
High performance: X Layer offers a rapid transaction verification process, eliminating the drawn-out wait times encountered on other networks. One of the speediest ZK-proof algorithms and a cutting-edge hardware configuration make this possible.
