DAG, directed acyclic graph, is a distributed-ledger technology that links transactions together directly without miners or blocks.

Currently (January 2018) there are three major DAG-based cryptocurrencies: Byteball, IOTA, and Raiblocks.

There is a wiki article comparing Byteball and IOTA.

Here is a table detailing differences among them. See the Cryptocurrency subreddit thread[1] for further discussion.

Comparison

  Byteball IOTA Raiblocks/Nano
Address reuse Yes Not after sending[2] Yes
Chain type Main chain DAG[3] PoW DAG[4] dPoS DAG+Blockchain[5]
Confirmation time (theoretical) 30 seconds[6] Instant[7] Instant[8]
Confirmation time (current) ~10 minutes?[9] Minutes to hours[10] to a day?[11] ~10 seconds[12]
Consensus Mainchain[13] deterministic[14] Minimal PoW[15], probabilistic[16] Weighted dPoS voting[17]
Developer ownership 1%?[18] 5%?[19] 4.8%?[20]
Distribution Free airdrops[21], 1% premine[22] Public ICO. No premine[23] Manual mining via captcha[24]
Distribution complete No[25] Yes[26] Yes[27]
Divisibility 1 GBYTE: 1 billion Bytes[28] 1 MIOTA: 1 million IOTA[29] 1 XRB: 1024 raw[30]
Fees Very small, based on size of data stored No fees No fees
Focus 1 GBYTE: 1 billion Bytes 1 MIOTA: 1 million IOTA 1 XRB: 1024 raw
Divisibility 1 GBYTE: 1 billion Bytes 1 MIOTA: 1 million IOTA 1 XRB: 1024 raw

Focus Smart contracts.

Storing arbitrary dataValuetransfer

Internet of Things (m2m) Value transfer (h2h)
Inflation None/Deflationary (minus distribution) None/Deflationary None/Deflationary
Offline transactions Via blackbytes? Yes Yes?
Partnerships A few? Many None as of 2014?
Public team Partially? Yes Yes
Privacy Yes via Blackbytes Eventually,
