Introduction

Patract Open Platform’s goal is to promote the large-scale popularization of Wasm contract technology in the Polkadot ecosystem. Patract Open Platform (POP for short, Wasm Contract Technology Alliance) will jointly promote the construction of public infrastructure and the evolution of contract technology, and provide brand promotion and capital support, then creating a strong alliance for Wasm contract ecosystem.

Wasm Contract Progress

Phala — ink! Contract development Github

Phala, as the privacy protocol project of the Polkadot Ecosystem is developing pink! — Ink! contract development executed off-chain in a trusted environment. A large refactor has been completed and is being merged. This PR work will be continued and the merger is expected to be completed in mid-October.

Cycan — GVM Bridge Github

GVM Bridge is a set of virtual machine intermodulation systems. Through the GVM Bridge system and the VM interconnection protocol, smart contracts between VMs can be invoked to achieve resource consolidation, and resources from different VMs can be used immediately without migration, thus improving resource utilization.

GVM Bridge will provide the GVM Bridge Framework component and the ABI conversion tools Trans4WABI and Trans4EABI for converting WASM ABI to VM GABI and EVM ABI to VM GABI respectively. The WASM-Proxy pallet and the EVM-Proxy pallet specifically implement the WASM VM and EVM calls.

GVM Bridge V0.1.0

  • Developed independent chain contract intermodulation related features based on the substrate chain.
  • Write the GVM-Bridge documentation, and to complete the use part of the documentation with the calling rules.
