After months of development and testnet deployment, the POL upgrade is now live on the Ethereum mainnet. Polygon Labs, the team behind the Ethereum sidechain, Polygon, sees this as a significant milestone for the project. The upgrade, known as Polygon 2.0, aims to make the network more scalable, secure, and user-friendly. One of the key changes is the implementation of a new consensus mechanism called proof-of-stake liquidity (POSL), which the developers claim is more efficient. Validators will need to stake their native tokens and liquidity to participate in the network. The liquidity provided by validators will be used to boost the liquidity of decentralized exchanges (DEXes) running on the sidechain. This will create a low-fee, highly scalable environment for users to swap tokens. The team also introduced POL, a token that will power a multichain ecosystem and be used for settling fees and governance. It remains to be seen if this update will support MATIC prices in the long run, but currently, MATIC is showing positive momentum and has already recovered from recent lows.
