Key Takeaways
- Polygon sidechain processes transactions off Ethereum’s main chain to lower costs, reduce congestion, and increase speed, while still committing data to Ethereum for finality.
- The network uses MATIC as a transaction fee token and staking asset, encouraging user participation while supporting security and validator incentives.
- Polygon combines features from sidechains and layer 2s, giving developers a fast, scalable environment without sacrificing Ethereum’s toolset and compatibility.
- Access to Polygon is straightforward through MetaMask, exchanges, dApps, and bridges, making it easy for users to interact with the network or move assets.
Polygon started as a project known as Matic Network in 2017 when a small team of engineers set out to reduce Ethereum’s mainnet strain. Back then, developers struggled with high fees and slow transaction speeds. Over time, Polygon crypto evolved into what many refer to as the Polygon blockchain—a robust infrastructure built with user needs in mind.
On November 16, 2023, the network recorded 16,449,264 transactions in one day—an impressive milestone that caught users’ attention. More than 1 million transactions pass through the network daily, signaling strong engagement.
In this article, we’ll explore the Polygon network, discuss Polygon coin (often called Polygon MATIC), and examine its benefits and drawbacks.
What is Polygon Network?
Polygon Network is a blockchain platform designed to improve Ethereum’s performance and attempt to solve the blockchain trilemma. It provides an alternate transaction pathway without sacrificing the security inherited from the base chain. By grouping transactions and processing them off the main chain, the Polygon blockchain increases throughput and reduces user fees.
Polygon is built to be compatible with Ethereum’s smart contract language. Developers can easily port their decentralized applications (dApps) to it and take advantage of lower costs and quicker confirmations while still enjoying many of Ethereum’s security features.
What is MATIC?
MATIC is the native token of the Polygon ecosystem and is often called the Polygon coin. MATIC functions in two key ways:
- First, it is used for paying transaction fees when interacting with various dApps on the Polygon platform.
- Second, it is the staking asset that validators and delegators commit to secure the network.
By staking MATIC, users support the network’s operation and receive rewards in return. Thus, MATIC is essential to the Polygon blockchain, facilitating its day-to-day transactions and overall security.
Matic Tokenomics
The tokenomics of MATIC are designed to balance incentives for network users and security providers. Here are some fundamental points:
- Total Supply: The maximum supply of MATIC tokens was fixed at 10 billion. Many of these tokens are already in circulation, while the remainder is scheduled to be released gradually over several years.
- Allocation: Tokens were distributed among various stakeholders, including the team, early investors, advisors, staking rewards, and the network’s foundation. This allocation supports ongoing development, community initiatives, and operational expenses.
- Deflationary mechanism: A fraction of users’ fees is burned, meaning those tokens are permanently removed from circulation. This reduces the circulating supply over time, potentially increasing the value for holders.
- Staking Rewards: Validators and delegators who secure the network are rewarded with new MATIC tokens. The reward system is aligned with a modest yearly emission rate and is carefully calibrated to encourage participation without causing significant inflation.
These measures combine to ensure that, over time, the incentives for securing and using the Polygon network remain attractive even as the ecosystem grows.
How Does Polygon Work?
Polygon operates on a unique framework that blends the strengths of both sidechains and layer 2 protocols while connecting closely with Ethereum. The network relies on its own dedicated set of validators and a consensus mechanism based on proof of stake.
When discussing blockchain scaling, distinguishing between sidechains and layer-2 solutions helps clear up some confusion. Both ideas involve processing transactions off the main chain, but they differ in security and independence:
- Sidechains: These are independent blockchains that connect to a main network using a two-way bridge. They run their own consensus protocols and do not inherit security from the main chain. This means that a breach in a sidechain will not necessarily impact Ethereum’s security.
- Layer 2 solutions: These are built on top of a layer-1 blockchain, such as Ethereum, and depend on its security. Examples include rollups. In this arrangement, while transactions are executed off-chain to increase speed, the underlying Ethereum chain secures the network’s final state.
Polygon’s design allows it to work in tandem with the Ethereum network. Transactions are processed on Polygon and then “committed” back to Ethereum through periodic checkpoints. This process, which involves bundling transaction data and submitting a summary to Ethereum, is similar to what you might expect from a sidechain.
However, it is important to understand that a sidechain operates on its own set of rules and consensus methods. With Polygon, validators process transactions quickly on their own network and provide evidence of those transactions on Ethereum, combining independent operation with a tether to Ethereum’s security.
What Problem Does Polygon Solve?
Polygon addresses several key issues that users and developers have long encountered on Ethereum:
- Reducing Congestion: During periods of high demand, Ethereum’s transaction fees can soar, slowing confirmation times. By processing transactions off Ethereum and consolidating them into checkpoints, Polygon reduces congestion for both networks.
- Lower Transaction Fees: Users benefit from significantly lower fees when using Polygon. This is crucial for smaller transactions and for dApps that handle large volumes of data.
- Faster Processing: With quicker block times, the network processes transactions far faster than Ethereum does on its main chain. Polygon speed benefits users and encourages more interactive applications, such as gaming and social apps.
- Enhanced Scalability: Developers gain flexibility to deploy and scale their applications without worrying about the heavy costs or long wait times that Ethereum users often experience.
This arrangement offloads much of Ethereum’s transactional burden, allowing it to maintain a high level of security and decentralization while still serving as a settlement layer.
Polygon vs Ethereum
Ethereum remains the foremost platform for decentralized applications, known for its security and vibrant ecosystem. Polygon, by contrast, offers scalability and speed.
While Ethereum processes transactions directly on its blockchain, Polygon aggregates transactions off-chain and periodically commits them to Ethereum.
Below is a comparison table to illustrate the differences:
| Feature | Polygon | Ethereum |
|---|---|---|
| Transaction Speed | Processes transactions in a few seconds, handles millions daily | Slower block times, around 12–15 seconds per block |
| Transaction Fees | Significantly lower (fractions of a cent) | Often high during congestion |
| Scalability | Built to support high throughput with sidechains & rollups | Limited by network congestion and block size |
| Security | Uses its own proof-of-stake but commits proofs to Ethereum | Highly secure, fully decentralized |
| Developer Tools | Ethereum-compatible, easy migration of dApps | Extensive, mature ecosystem |
| Use Cases | Ideal for high-frequency, low-cost applications | Best for applications requiring maximum security |
| Network Role | Aggregation and processing layer offloaded from Ethereum | Settlement and finality layer |
Advantages of Polygon
Polygon offers several notable advantages:
- Enhanced throughput: The ability to process more transactions quickly benefits dApp developers and users.
- Reduced costs: Lower fees make it accessible for a broader range of applications, including those with micropayments.
