Polygon is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. It allows for aggregation scalable solutions on Ethereum supporting a multi-chain Ethereum ecosystem.
We were also impressed with Ethereum interoperability and security with native support for arbitrary message passing (tokens, contract calls etc), bridges to external systems. An additional layer of validators regularly checks the validity of any Polygon chain to ensure the security of the whole network. Modular ''security as a service'', provided either by Ethereum or by a pool of professional validators.
For our players, Polygon offers fast and low cost transaction speed as Polygon supports ~7.2k transactions per second. The Matic Network enables low-cost transactions through achieving economies of scale by doing a large number of transactions on the Block Producer layer which ensures low cost, and then subsequently batching the proofs of the Matic blocks using the Merkle root of the blocks to a highly decentralized mainchain (for ex. Ethereum) using a decentralized layer of PoS Stakers.
In terms of future proofing the project, Polygon's open community with a large number of developers and support network is massively appealing. It also benefits from Ethereum's industry dominance, established tech stack, tools, languages, standards and enterprise adoption.
Overall Polygon is a balanced solution that meets our blockchain tech requirements without any major flaws.
