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%? 5%? 4.8%?
Distribution Free airdrops[18], 1% premine[19] Public ICO. No premine Manual mining via captcha
Distribution complete No Yes Yes





Byteball IOTA Raiblocks
Divisibility 1 GBYTE: 1 billion Bytes 1 MIOTA: 1 million IOTA 1 XRB: 1024 raw
Fees Very small, based on size of data stored No fees No fees
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,

Test mixer

Not on chain
Quantum resistant Not yet. Via NTRU Yes No?
Smart contracts Yes Not yet? No?
Supply (Current) 645,222 GBYTE 2,779,530,283 MIOTA 133,248,290 XRB
Supply (Total) 1,000,000 GBYTE 2,779,530,283 MIOTA 133,248,290 XRB
Transaction limit (theory) Unlimited? Unlimited Unlimited
Transaction limit (current) 10 TPS 500 TPS in stress tests 7k TPS on Testnet?
