Polkadot is a blockchain network that wants to make it easier for more people to become validators. Validators are important because they help to confirm transactions and keep the network running smoothly. Right now, there can only be 297 active validators at a time, and they need to have a lot of DOT (the network's currency) to have a chance at being chosen. This makes it hard for new, independent validators to join.
The proposal suggests increasing the number of active validators to 500, which would make it easier for more people to become validators and lower the amount of DOT needed. This would help make Polkadot more open and accessible to individuals. There are also some pictures and links provided to help explain the proposal in more detail.
