The CAC 40 at twelve months, sealed
Forty forecasters, one index, twelve months. Every call on a CAC 40 name sealed before the fact, then settled against that constituent's own drift and volatility — never against a flattering fifty-fifty.
What you commit to
The scope
One call on any CAC 40 constituent, read straight from the index — the forty names exactly as the registry carries them, priced in euros at the Paris close.
The horizon and the deadline
One directional or target-price call, at a horizon of 12 months or longer, sealed no later than Dec 31, 2026. After that the ledger closes and nothing more can be added to it.
Before the fact
Your call is hashed and timestamped the moment you publish it, then committed to a Bitcoin block. You cannot edit it, we cannot edit it, and anyone can check it — that is the whole difference between this ledger and a thread.
Set the horizon to 12 months on the form — that is what puts your call on this ledger.
The ledger
Nothing is sealed on this ledger yet.
The register starts with the first call published. Yours would carry the earliest timestamp on it — the one row nobody can take later.
