Who pays the miners later

Miners guard the network because they are paid. Today almost all of that pay is new coins. As new coins dry up, the s in each payment have to take over. This page lets you check the arithmetic.

Why it matters to you

Security is only as strong as what miners earn. If fees can’t replace the new coins, fewer miners stay, and an attack gets cheaper. It’s the most common serious doubt about Kaspa, and about Bitcoin too.

How it works: the break-even fee

Pick how many payments a second the network carries. The line shows the average fee each one would need, in KAS, so that miners earn as many KAS a second as they do today.

Payments a second 100

Year 2040

Arithmetic, not a forecastToday’s new coins a second, minus that year’s, divided by payments a second. It counts KAS, not dollars; what a KAS is worth then is unknown.

What isn’t settled

Two things nobody knows: how many payments Kaspa will carry, and what a KAS will be worth. If the price rises, miners can earn the same in dollars with fewer KAS. Treat any confident answer, either way, with care.
