Why Was Polygon Created?

Polygon (formerly Matic Network) was created to address Ethereum's scalability limitations. While Ethereum mainnet offers world-class security and decentralization, it can only process about 15 transactions per second, and gas fees can spike to tens or hundreds of dollars during periods of high demand. Polygon provides an EVM-compatible environment where the same Solidity smart contracts run with 2-second finality and sub-cent fees.

Transaction Speed Comparison

Ethereum mainnet averages about 13-second block times and roughly 15 TPS. Polygon PoS produces a new block every 2 seconds and can handle over 7,000 TPS in real-world conditions, making it orders of magnitude faster for end-user applications such as games, social platforms, and payment systems.

Gas Fee Comparison

A simple ETH/POL transfer on Ethereum can cost $2–$50 depending on network congestion. The same transfer on Polygon typically costs $0.001–$0.01. For DeFi operations like swaps or liquidity provision, the savings are even more dramatic, enabling micro-transactions and high-frequency interactions that would be economically impossible on mainnet.

Security Model Differences

Ethereum mainnet is secured by over 900,000 validators running Proof-of-Stake consensus. Polygon PoS uses a separate validator set of 100 validators with economic stake as the security guarantee. While this is less decentralized than Ethereum, Polygon PoS periodically checkpoints its state to Ethereum mainnet, inheriting a degree of Ethereum's security for finalized transactions.

EVM Compatibility

Polygon PoS is fully EVM-compatible, meaning any tool, wallet, library, or contract that works on Ethereum also works on Polygon without modification. MetaMask, Hardhat, Foundry, ethers.js, web3.js, and every major Ethereum development tool supports Polygon out of the box.
