Polygon, our Layer 2 solution, will be a separate blockchain that is based on Ethereum and uses the same Ethereum addresses. This means that many smart-contract features that currently work with our domains will continue to function on the Layer 2. It employs a different consensus mechanism, i.e. PoS (Proof-of-Stake). Alternatively, there is also a more robust consensus system known as Plasma that involves 1-week time locks on bridging to and from Ethereum.
The biggest advantage of moving to a Layer 2 scaling solution is that transactions are handled in bulk outside of the Ethereum mainnet (Layer 1), greatly reducing gas fees and allowing us to resume paying them on behalf of our users. This helps greatly increase both accessibility and utility for everyone moving forward.
