Revision as of 18:43, 21 January 2019
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
[Obyte] | 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[31] | No fees[32] | No fees[33] |
Focus | Smart contracts[34], Storing arbitrary data[35], Value[36] transfer[37] | Internet of Things (m2m)[38] | Value transfer (h2h)[39] |
Inflation | None/Deflationary (minus distribution)[40] | None/Deflationary[41] | None/Deflationary[42] |
Offline transactions | Via blackbytes?[43] | Yes[44] | Yes?[45] |
Partnerships | A few?[46] | Many[47] | None as of 2014?[48] |
Public team | Partially?[49] | Yes[50] | Yes[51] |
Privacy | Yes via Blackbytes[52] | Eventually[53], Test mixer[54] | Not on chain[55] |
Quantum resistant | Not yet. Via NTRU[56] | Yes[57] | No?[58] |
Smart contracts | Yes[59] | Not yet?[60] | No?[61] |
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?[62] | Unlimited[63] | Unlimited[64] |
Transaction limit (current) | 10 TPS[65] | 500 TPS in stress tests[66] | 7k TPS on Testnet?[67] |
