Often this means creating a new blockchain, or = at least a sidechain to an existing blockchain. This writeup proposes an a= lternative method without launching a separate blockchain or sidechain, whi= le achieving security similar to federated sidechains and additional benefi= ts to privacy and smart-contract-patching.
