What Is Polygon? The Complete Guide to Understanding Layer 2 Blockchain Networks

Polygon Overview

Polygon, formerly known as Matic Network, is a Layer 2 scaling solution for Ethereum, purpose-built to address the network’s scalability issues, slow transaction speeds, and high gas fees. To truly understand what Polygon is, recognize that it serves as infrastructure empowering developers to create scalable, user-friendly blockchain applications.

Polygon’s History and Evolution

Polygon was launched in 2017 by Indian founders Jaynti Kanani, Sandeep Nailwal, and Anurag Arjun. Initially branded as Matic Network, the platform rebranded as Polygon in 2021 to reflect a broader vision of offering diverse scaling solutions for Ethereum.

How Polygon Works

What is Polygon from a technology perspective? Polygon functions as a framework for building and interconnecting Ethereum-compatible blockchain networks. Its multi-layered architecture includes:

1. Ethereum Layer

The foundational layer delivering transaction security and finality.

2. Security Layer

An optional layer that provides validator-as-a-service for additional security.

3. Polygon Networks Layer

An ecosystem of independent blockchains built on Polygon.

4. Execution Layer

The layer that executes smart contracts and handles transaction processing.

Key Features of Polygon

You can’t fully answer what Polygon is without covering its main features:

High Scalability

Polygon supports up to 65,000 transactions per second—vastly outpacing Ethereum’s mainnet throughput.

Low Transaction Costs

Polygon offers extremely low gas fees, making transactions accessible for all users.

Ethereum Compatibility

Polygon is fully compatible with Ethereum, facilitating seamless application migration.

Security
