In a blog post, Polygon recalled the highlights of the previous year, 2021, while announcing three major developments for 2022.
The year 2021 saw Polygon add six new solutions: SDK, Avail, Hermez, Nightfall, Miden and Zero, with its focus on ZK (Zero-Knowledge) cryptography.
In a $250 million deal, Polygon announced its merger with roll-up platform Hermez Network in August 2021. Hermez was eventually assimilated into the Polygon ecosystem and became a component of Polygon’s solutions under the name Polygon Hermez.
Likewise in November, Polygon Miden, a STARK-based, EVM-compatible rollup, was born. Polygon Miden’s primary component, Miden VM, a STARK-based virtual machine, aims to solve the difficulty of ZK rollups in enabling arbitrary logic and transactions, including those of the EVM (Ethereum Virtual Machine).
