How exactly the consensus in Multichain work:
1- No proof of work, does it means validation-node will validate all new transactions to append in new block, but not entire blockchain. Am I right ?
2- Technical process: Suppose that 4 nodes are permitted to mine, so for example if a transactions happen in node1, will node1 broadcast the transaction(s) to other permitted node(s) to help validate the transaction(s) ? and node that has longest chain of transaction(most powerful computation node) will be voted as the most sufficient block to append in the Blockchain and again does it need to broadcast the longest transaction to other permitted node to validate or wait until other permitted node finished their validation un til it can write/append into new block ?
