This Thursday night, the Privacy On Polkadot online speech event initiated by ZKValidator was hosted by the founder of Patract — Lipeng Yue, the co-founder of Automata Network — Deli Gong, and the co-founder of Phala Network — Marvin Tong, the co-founder of Manta Network — Shumo Chu, the co-founder of zCloak Network — Zhang Xiao, etc. participated in privacy projects in the Polkadot ecosystem.

With the development of the Wasm contract ecosystem and the continuous improvement of the underlying facilities, more and more Polkadot parachains and DApp developers have paid attention to Wasm contracts. Wasm contracts are developed by using chain-level language Rust or AssemblyScript. The deployment and operation costs are very low, and they can get more imagination than the Ethereum EVM contract. MathChain is keenly aware of the trend of Wasm contract technology innovation and joins Patract Open Platform.

MathChain is a Layer 2 blockchain project based on Substrate. It is committed to lower the threshold for massive users to enter the…

Recently, the smart contract platform Clover announced to join Patract Open Platform and partnered with Polkadot Wasm contract technology lab — Patract to jointly promote the Wasm contract technology in the Polkadot ecosystem.

Clover supports Ethereum projects and developers to migrate their contracts to Polkadot seamlessly. They can run EVM contracts with minimal changes, and combine the Consensys tool suite to quickly copy DApps and deploy them to Clover.

With the gradual development and improvement of the Wasm contract ecosystem and underlying facilities, Clover is very optimistic about the Wasm contract technology, which is very efficient in terms of speed…
