Kaspa vs Bitcoin
How Kaspa and Bitcoin differ on speed, security model, supply and mining.
Bitcoin and Kaspa share the same security model: proof of work, no staking, the most work wins. The difference is structure. Bitcoin keeps one chain and slows blocks to every 10 minutes to avoid collisions. Kaspa keeps every parallel block in a blockDAG, so it can run 6,000 times more blocks in the same time.
In the time Bitcoin produces one block, Kaspa produces about 6,000.
Kaspa vs Bitcoin: side by side
| Kaspa (KAS) | Bitcoin (BTC) | |
|---|---|---|
| Launched | November 2021 | January 2009 |
| Consensus | Proof of work (GHOSTDAG blockDAG) | Proof of work (Nakamoto longest chain) |
| Mining algorithm | kHeavyHash | SHA-256 |
| Block time | 0.1 s (10 blocks per second) | 10 minutes |
| Structure | BlockDAG: parallel blocks are all kept | Single chain: simultaneous blocks become orphans |
| Supply | Capped at about 28.7 billion KAS | Capped at 21 million BTC |
| Issuance | Smooth: reward drops about 5.6% every month, halving yearly | Halving every 210,000 blocks (about four years) |
| Launch | Fair launch, no premine or pre-sale | Fair launch, no premine |
| Hardware | kHeavyHash ASICs | SHA-256 ASICs |
The short version
- Bitcoin is the most proven, most valuable and most widely held proof-of-work network.
- Kaspa keeps Bitcoin's trust model but confirms transactions in seconds rather than tens of minutes.
- Kaspa's emission reduces smoothly every month instead of in four-yearly halvings.
Frequently asked questions
Is Kaspa faster than Bitcoin?
Yes, by design. Kaspa produces a block every 0.1 seconds versus Bitcoin's 10 minutes, so a Kaspa transaction is in a block almost immediately and gathers many confirmations within seconds.
Is Kaspa a Bitcoin fork?
No. Kaspa is a separate network with its own code, launched in 2021. It uses proof of work like Bitcoin but replaces the single chain with a blockDAG and the GHOSTDAG consensus protocol.
Which is more secure, Kaspa or Bitcoin?
Both rely on proof of work and resist attackers with less than half of the hashrate. Bitcoin has far more total hashrate and a much longer track record, which matters for real-world security.
