TrustNote is a Directed Acyclic Graph (DAG) based distributed ledger designed to “enabling fast and scalable decentralized applications for everyone on every device at a low cost”.

Instead of the classical blockchain-based data structure, TrustNote stores transactions in a DAG structure, which greatly increases the number of concurrent transactions and ensures faster transaction. On the top of the DAG consensus model, a proof-of-work based consensus scheme is further developed to encourage fair participation through mining.
