Perhaps anyone can advertise themselves (by e.g. locking some bonded amount= on the blockchain with a `OP_CHECKSEQUENCEVERIFY`) as being willing to act= as trusted executors of smart contracts. Participants then select such executors they believe to be trustworthy, and= what voting quorum of the selected executors is sufficient to convince the= participants of the correct execution of the smart contract. Of course, more choices, more cognitive effort for you mere humans, so prob= ably not a good idea in general.

Often this means creating a new blockchain, or= at least a sidechain to an existing blockchain.
