Abstract
A blockchain-based network arrangement includes member nodes joined by a multicast network including a trusted node configured for creating at least one cryptographic key and for distributing copies of the cryptographic key over the multicast network as a multicast blockchain transmission to other member nodes. A requesting node outside the member nodes is configured for initiating a smart contract containing its blockchain address and for sending the smart contract as a request for group access with an address of the trusted node. The trusted node is configured for receiving the smart contract and a decides to accept or reject the smart contract, and records the decision in the blockchain by updating the smart contract. An accept decision results in a member node sending the cryptographic key to the requesting node.
