Directed acyclic graph
From Obyte Wiki
DAG, directed acyclic graph, is a distributed-ledger technology that links transactions together directly without miners or blocks.
Currently (April 2018) there are three major DAG-based cryptocurrencies: [Obyte], IOTA, and Nano (was Raiblocks).
Here is a table by Reddit u/Qwahzi detailing differences among them. See the Cryptocurrency subreddit thread[1] for further discussion.
Comparison
