As a[ Layer 2 solution](https://coinmarketcap.com/headlines/news/ethereum-layer-2-scaling-solution-optimism-preliminary-mainnet-january-15/) utilizing a network of proof-of-stake validators for asset security, staking is an integral part of the Polygon ecosystem. Validators on the network will stake their MATIC tokens as collateral to become part of the network’s PoS consensus mechanism and will receive MATIC tokens in return.
Members of the network who do not wish to become validators can delegate their MATIC tokens to another validator, but will still take part in their staking process and earn staking rewards.
In addition to the proof-of-stake checkpointing, Polygon uses block producers at the block producer layer to achieve a higher degree of decentralization. These block producers give finality to the main chains using checkpoints and fraud-proof mechanisms.
