Satoshi's Engine
by Moose
How mining pays, and what survives market cycles.
Live
Loading the blocks…
Real blocks, live from the Kaspa network.
Parents per block, last 100
Thick line: selected parent.
More depth
Since Crescendo, a block can name up to 16 parents (KIP-14). Most name a handful: every extra parent is another block this one saw and kept.
Buried in blue
Depth counts blue blocks, not height.
Pin a block to watch it sink.
The moving edge is called the tips.

Buses = blocks · riders = txs · ~0.1 s

Counting buses…
Sources
Buses: real blocks live from api.kaspa.org, read-only, or a recorded sample when it can’t be reached. Riders are each block’s transactions minus the first one, which pays the miner. Bitcoin’s bus is its ~10 minute design target, not a live feed. The street idea comes from TxStreet.

Blocks while you wait
Pick a wait and watch the strip. Every tick is a real block that arrived during it.
Compare: Ethereum fills one 12 second slot in that time, Bitcoin one block per 600 seconds. Both rows are design targets, not counts.
The short version
- 1It's proof-of-work, like Bitcoin.
- 2Ten blocks a second, all of them kept.
- 3An hour of Bitcoin safety in 1 to 3 seconds.
- 4Fair launch, fixed supply, most of it already mined.
- 5Fees are the open question.

The tour
About 32 minutes in total, plus the demos.
