Polygon’s Breakthrough Year: 2021 in Review

Welcome to 2022! This is shaping up to be another amazing year for the Polygon ecosystem. But after an absolutely breakthrough 2021, it's got big shoes to fill.

Over the past year, Polygon made big strides toward accomplishing its mission of bringing the next billion users to Ethereum. The network’s low-fee infrastructure attracted some of the biggest projects in decentralized finance (DeFi) and non-fungible tokens (NFTs), including Aave, SushiSwap and OpenSea. Adoption soared with unique addresses topping 120 million. And the core development team is making sure the growth will continue into the foreseeable future by assembling an unrivaled collection of zero knowledge efforts under one roof.

Data Availability is Not Data Storage

Recall this grade school experience: you raise your hand and ask, “Can I go to the bathroom?” To which your teacher responds with “I don’t know. Can you?” Might seem far fetched, but this is a perfect entry point to understanding the difference between data availability and data storage. Let's bring this analogy close to […]

The Future is Now for Ethereum Scaling: Introducing Polygon zkEVM

We all know that Ethereum needs to scale, and we at Polygon believe that zero-knowledge (ZK) tech is the most promising pathway to get there. But that path has often seemed as if it would be long and winding. The conventional wisdom has been that the crypto space would need many years to develop Layer […]

Polygon Reaches First Sustainability Milestone by Achieving Network Carbon Neutrality

Polygon has made a major first step toward becoming carbon negative with the retirement of $400,000 in carbon credits representing 104,794 tonnes of greenhouse gasses, or the entirety of the network’s CO2 debt since inception.  The milestone comes after Polygon in mid-April released its Green Manifesto, part of its broader vision for sustainable development. The […]

Polygon Avail Launches on Testnet to Turn Monolithic Chains Modular

If we want the entire world to join Web3, blockchains will need to handle more transactions. Monolithic blockchains can’t scale because they’re asked to perform too many tasks (execution, settlement, and data availability) at once. But if chains were able to focus on just one part of the stack at a time, the entire ecosystem […]
