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 (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 |
| Byteball | IOTA | Raiblocks | |
|---|---|---|---|
| Focus | Smart contracts. | 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, | 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? |
