Directed Acyclic Graph
A data structure used in some distributed ledgers where transactions are linked to previous transactions rather than blocks.
For high-frequency IoT networks (like swarm robotics), standard blocks are too slow. We use DAGs (like IOTA or Hedera) where every transaction confirms two previous ones, allowing the network to speed up as more devices join.
