Kaspa (KAS) has just set a new benchmark for blockchain speed, achieving 10 blocks per second on its mainnet without compromising decentralization or Proof-of-Work (PoW) security. This milestone is not just an incremental improvement — it’s a 600x faster block rate than Bitcoin.
Why This is Groundbreaking
Most PoW blockchains, like Bitcoin and Litecoin, process transactions slowly to maintain consensus and network security. Kaspa produces 10 blocks each second, far outpacing Bitcoin’s 10-minute block time and Litecoin’s 2.5-minute block time. Kaspa? It processes 10 blocks every second — on mainnet — and is still fully decentralized.
The Proof-of-Work Speed Problem
In traditional blockchains, trying to mine blocks too quickly increases the risk of orphan blocks (valid blocks that get discarded because another block was accepted first). It reduces efficiency and compromises network security. That’s why Bitcoin and similar chains maintain low block rates.
Kaspa’s Breakthrough: GhostDAG & BlockDAG
Kaspa uses a BlockDAG structure with the GhostDAG consensus protocol, developed by Yonatan Sompolinsky (one of the key researchers in Bitcoin scalability). Instead of discarding parallel blocks, Kaspa keeps them all and orders them in a way that maintains consensus, allowing much higher throughput.
From 1 to 10 Blocks Per Second: The Crescendo Upgrade
In 2024, Kaspa rolled out the Crescendo upgrade, increasing its mainnet speed from 1 block per second to 10 blocks per second. It marked a significant milestone in the Kaspa roadmap, achieved without compromising decentralization or security.
Why This Matters
- Ultra-fast confirmations: Transactions are confirmed almost instantly.
- No PoS trade-offs: Kaspa remains 100% Proof-of-Work, avoiding Proof-of-Stake’s potential centralization risks.
- Scalable & secure: GhostDAG solves the scaling bottleneck of traditional PoW chains.
No Competition in PoW Speed
Kaspa’s performance in blocks per second (bps) is outlined below for comparison:
| Blockchain | Blocks Per Second |
|---|---|
| Kaspa | 10 |
| Bitcoin | 0.0016 |
| Litecoin | 0.0066 |
| Dogecoin | 0.016 |
| Monero | 0.0083 |
| Ethereum | ~0.23 |
| Solana | ~0.4 |
| XRP | ~1.5 |
| Sui | ~0.25 |
No other Proof-of-Work blockchain has achieved a 10 bps block reward on mainnet.
What’s Next for Kaspa
- DAGKNIGHT consensus upgrade — will further improve performance.
- Rust migration — faster and more efficient codebase.
- Smart contracts & L2 solutions — opening doors for DeFi and dApps.
Conclusion
Kaspa has proven that Proof-of-Work can scale without sacrificing decentralization or security. In a crypto world full of trade-offs, Kaspa’s 10 bps mainnet performance sets a new standard — and no other PoW blockchain is close.
