Polygon Zero is a layer 2 scaling solution for Ethereum, powered by Plonky2. A groundbreaking prover system, which generates zk proofs faster than any other existing tech. Plonky2 supports efficient recursive proof generation allowing Polygon Zero to scale horizontally – meaning the throughput of the protocol is limited not by the weakest nodes on the network, but only by the total compute available.

This week, Anna chats with Dean Tribble, co-founder and CEO of Agoric. Dean walks us through the landscape of programming languages and Agoric’s philosophy behind building a blockchain that has Hardened JS as its smart contract language. We hear about the two big challenges in using JavaScript in blockchain development, malleability and non-deterministic, and how Agoric addresses these. Dean explains the security implications of many popular blockchain languages and how this led them to build Agoric’s smart contract infrastructure allowing JavaScript functions to run with specific access control – leaving the money management to the larger framework. We touch on what to expect from the upcoming development phases of Agoric, various bridging partnerships to come, and last but not least – if, when and how they envision ZK roll-ups getting implemented into the stack.
