Sealing is free.
Being right is billable.
You write a prediction and seal it. The text turns unreadable, even for you; its hash and date are on record. Opening it costs $29.00; leaving it shut is free.
You seal
You write the prediction and the figure that will settle it. Both go into the same hash, and neither can be softened afterwards.
It goes on the record
The seal enters an append-only register, with a serial number and a date. It is the entry that answers “show me the screenshot.”
You reveal
You check the source you named and decide. Revealing publishes the text with its original date for $29.00. The difficulty was fixed the day you sealed.

Sealing asks you to state which figure, in which source, against which threshold. The criterion travels inside the hash. One that cannot be settled is rejected on the spot.
Sealing is free. Declaring that something did not happen is free too. You pay when you open a text, or when you fix in advance that it opens by itself.
Before you write anything, check the register. It audits end to end from your browser, without taking our word for it.
