For pure consensus protocols, Erlang has the advantage you can trust every node, so you don't need a blockchain mechanism for handling it. You can pick among several algorithms: PAXOS and Raft comes to mind, the latter being a structured log as the blockchain, but without the Merkle construction.<br><br></div><div class="gmail_extra">The other thing to think about is the concept of acceptable latency. In a system like BitCoin, the latency for transaction confirmation is measured in minutes due to the proof of work obligation. In a node-setting, you want such stuff to happen quickly.<br></div><div class="gmail_extra"><br><br></div><div class="gmail_extra"><br clear="all"><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature">J.</div>
