Private workchains are workchains with their own sets of validators and rules, predetermined before the launch, which makes them attractive for commercial use. This is a fundamental release for the network, as it will give us the opportunity to compete on an equal footing with the likes of Hyperledger, Corda, or VeChain. Corporations aren't our main focus at present, but in order to become a worldwide decentralized operations system, we have to provide tools for all kinds of users, including commercial entities.
