Whatโ€™s difficult about zk proofs and scalability, and how does the Polygon zkEVM try to solve them? (1 minute read)

ZK proofs are time-intensive and expensive to generate. It can be difficult to build on top of most ZK rollups as they usually require a new coding language or dev environment. Polygon's zkEVM improves on proof-generation times, reducing costs. It can also run any Ethereum smart contract.

Explaining the zkEVM (2 minute read)

Layer 2 rollups batch user transactions together for cheaper gas costs while keeping most security guarantees of the Ethereum mainnet. Optimistic rollups publish periodic state roots to mainnet and rely on fraud proofs to ensure honesty. ZK rollups publish state roots to mainnet but also include cryptographic proofs of validity. They have stronger guarantees, but they are technically challenging. zkEVMs can run Solidity code on top of a ZK rollup.
