A guarantee is only worth what someone will sell it for. Every promise here can be backed, doubted, or challenged — so the price reflects belief and doubt together, not one side's opinion.
The coverage book
Coverage offered and doubt bid meet at each fee level, and the market clears at the lowest fee that fills. Every winner is paid the clearing rate, so honest bidding wins.
The positions
◇
Back
Join a coverage pool. Earn the fee on every job done right; pay when one goes wrong.
You are long on the workers.
≈
Doubt
Take the other side. Pay the going fee; get paid when a protocol fails more than its price says.
If the market looks too confident, doubt is how you say it with money.
!
Challenge
Spot one bad call. Post a bond against a specific verdict; if it is overturned, the judge's deposit pays you.
A wrong challenge loses the bond.
THE ARSON RULE · doubt is capped below the deposits already at stake, so causing a failure always costs more than doubting it can ever pay
