TrustNote is similar in design to, and influenced by DAG-ledgers like Byteball and IOTA. TrustNote takes the commonly used DAG consensus model a bit further and on the top of it, a proof-of-work based consensus scheme (TrustME consensus) is proposed to encourage fair and trustable witness node selection through mining. Most of today's DAG-ledgers have no incentives like mining. Without proof-of-work based incentives, it's much harder to achieve decentralized consensus and often weakening the consensus on which it is based. Inspired by DASH's two tier network architecture, TrustNote is trying to combine proof-of-work consensus and DAG ledger structure all together, building a more scalable and more secured distributed ledger system.
