iExec lead smart contract developer François explores the possibility of a PoA bridge and chain, working with the Polkadot and Substrate teams.
“The iExec network needs a business-specific chain to track deals between the different actors interacting on its cloud resources marketplace (computing, datasets and application buyers and sellers). The chain would be used to record all the contributions of these actors to trigger payments using PoCo (iExec’s Proof-of-Contribution algorithm). For private and consortium usage of the iExec Stack, a PoA bridge and chain can be setup to achieve such a business logic. For the public side, iExec has more requirements and is experimenting with Substrate to cover the missing points: a token-based PoS consensus, governance, upgradability, the use of wasm for new features, and interoperability as a Polkadot parachain.”
