Size of Blockchain
Each block on the blockchain and/or compute state in case of a smart contract based blockchain must be validated by multiple nodes. Each node has to manage a copy of the state and the blocks. While the chain increases in size as the days go by, maintaining and validating the whole blockchain becomes difficult and results in fewer full nodes in public blockchains, which poses a risk for decentralization.
For the Matic Network, the primary layer which provides decentralization may choose to store only the blocks of Matic Chain from the previous checkpoint to the next checkpoint. All previous transaction/block proofs have been submitted to the mainchain. This enables extremely low fidelity PoS nodes which can be run in very low-cost machines with low storage. In future, The Matic Network intends to enable mobile device based PoS miners too.
