The disclosed technology is generally directed to blockchain technology. In one example of the technology, a first transaction node of a hosted permissioned blockchain network is provisioned for a first consortium member of the hosted permissioned blockchain network. A shared pool of validator nodes of the hosted permissioned blockchain network is provisioned. The shared pool of validator nodes includes at least one validator node. The shared pool of validator nodes is shared among the plurality of consortium members. The validator nodes of the shared pool of validator nodes are configured for blockchain transaction validation based on a BFT consensus protocol. A second transaction node of the hosted permissioned blockchain network is provisioned for a second consortium member of the hosted permissioned blockchain network. Each transaction node of the hosted permissioned blockchain network is separate from each validator node of the hosted permissioned blockchain network.
