Submit to the Ledger

Make a Claim

Your claim becomes part of the permanent public record. Evidence accumulates. Your reputation reflects how your claims hold up over time.

TAIL verifies identity. Reality verifies truth.
Identity establishes accountability.
Evidence establishes credibility.
Time establishes trust.

CLAIM STANDARDSValid claims must be:
· Falsifiable — capable of being proven true or false
· Specific — clear enough that evidence can confirm or contradict it
· Non-trivial — not mathematical certainties, tautologies, or obvious facts

Examples of invalid claims: "2+2=4" · "The sky is blue" · "Water is wet"
Examples of valid claims: "Company X will reach $1B revenue by 2027" · "Policy Y causes outcome Z"

Claims that do not meet these standards will be removed from the ledger.

This is a public, permanent record. Your name and claim will be visible to everyone. Claims cannot be deleted — only resolved. Make claims you can stand behind.

Claim Type *

Statement: something you assert is true now. Prediction: something you assert will happen. Commitment: something you promise to do — predictions describe reality; commitments create obligations.

Your Claim *

Be precise. The clearer the claim, the more meaningful the verification.

Claim Origin *

Where this claim comes from. Immutable once submitted. "The person said this" and "someone says the person said this" are different trust levels — TAIL never blurs them.

Subject of the Claim *

The person or entity the claim is attributed to. You are the submitter; they are the subject.

Resolution Event *

How reality will judge this claim — declared now, before the outcome, so no one can move the goalposts later.
