Kaspa · Mainnet · Proof of work
Kaspa finds a proof-of-work block every 100 milliseconds. No validator committee, no staking, no leader schedule. Each glowing dot flying past is a block joining the network's blockDAG, at the rate mainnet actually runs.

Average is not typical. Proof-of-work block intervals are exponentially distributed, so the median gap is only 69% of the average (Bitcoin: about 6.9 min median vs 10 min average), while one block in eight takes more than twice the average. The race draws every proof-of-work wait from that distribution, and slotted chains wait for their next slot. Arbitrum and Base are Ethereum layer 2s: their blocks confirm fast but settle on Ethereum. Fees are typical costs for one stablecoin transfer as of September 2026 and move with network load and token prices; the Kaspa fee is a generous 0.001 KAS priced live.
Block race
Fourteen lanes, fourteen average block times. The bottom edge of each lane fills toward that chain's next block. Leave the tab open and watch the numbers drift apart.
Ten minutes
Bitcoin targets one block every ten minutes. In that same window, Kaspa produces six thousand. Bars use a logarithmic scale, otherwise everything but Kaspa vanishes.
Block times are protocol targets. Solana and Ethereum figures use slot time.
Why it works
Speed up Bitcoin and blocks start colliding. Two miners find a block in the same second, one gets thrown away, and security drains out with it. Kaspa keeps both.
Blocks mined at the same time all stay in the ledger. The GHOSTDAG protocol orders them afterwards, so parallel blocks add security instead of becoming orphans.
Miners burn real energy on kHeavyHash to find every block. There is no staking, no validator set to bribe, no leader to censor. The most work wins.
With a block every 100 ms your transaction is in a block almost immediately and stacks up confirmations by the dozen every few seconds, not one every ten minutes.
