LeoGlossary: Directed Acyclic Graph (DAG)

A data structure that builds new transactions on old ones. Each additional transaction have to reference older transactions before being accepted by the network.

Blockchain is different in that each additional block is referencing prior blocks, not transactions.

Directed Acyclic Graph (DAG) do not use miners like Proof-of-Work (PoW) blockchains do. This allows for high throughput speeds along with lower transaction fees.
