9.3 L2 Solutions

Polygon uses two L2 scaling solutions, called ZK-Rollups and

Optimistic rollups, that works on the concepts of zero-knowledge and

fraud proof respectively.

Please note that in the current architecture, Polygon has only

Ethereum as the base layer; however, as it matures, it has plans to

use the other Blockchains to be configured as the base, that would

ultimately make Polygon a cross-chain L2 platform.

9.4 Scalability and Performance

As per the Polygon promoters, this interoperable Blockchain can

achieve a scalability of up to 65,000 TPS with a block time of just 2

seconds

(https://cryptobriefing.com/behind-polygon-mission-

become-aws-ethereum/).

However,

theoretically,

Polygon

can

achieve a far greater scalability of millions of transactions per second

by adding more side chains.

9.5 Development

The step-by-step instruction for the development and testing of

DApps can be found at the Polygon’s website https://sdk-

docs.polygon.technology/docs/overview/.

The development engagement is pretty high in the Polygon

Blockchain. In fact, many of the original developers of Solidity on

Ethereum, reskilled themselves to work on Polygon, as the

underlying language is the same, i.e. Solidity, and only the

configuration part needs some extra attention.

9.6 Wallet

Polygon is supported by a huge number of wallets of different types.

Ethereum’s existing Metamask browser wallet, WalletConnect mobile

wallet, Coinbase wallet, Math and Onto cross-chain wallets, SafePal

hardware wallet etc., are a few of them.
