+The order of processing nodes is determined based on the server reputation system, *ヒジリ(hijiri)*. Hijiri calculates the reliability of servers based on: 1) uptime, and 2) number of successful transactions processed.

 Consensus in Sumeragi is performed on individual transactions and on the global state resulting from the application of the transaction. When a validating peer receives a transaction over the network, it performs the following steps in order:
 
 * validate the signature (or signatures, in the case of multisignature transactions) of the transaction
