We're joined by Igor Barinov, the tech lead of the POA Network. The POA Network achieves a reduction in transaction costs by many orders of magnitude by having a set of trusted validators. All validators must be US public notaries, so their identities are known and legal recourse against them can be taken in the offchain world. We also talk about the xDai network, which enables Dai transactions on a POA chain: Dai are transferred into a smart contract on the mainnet and then become available to be transferred at much lower cost on the POA Network. Similarly, they can be transferred out of the xDai network and become available again on the mainchain. We talk about use cases, governance, and limitations.
