Every time a claim is made on the blockchain whether it’s a university verifying a degree, a bank confirming a credit score, or a government issuing a digital ID it requires a "stamp" of cryptographic proof.
Within the Sign Protocol, $SIGN acts as the gas for attestations.
The Mechanism: When an "Attester" (the issuer) creates a proof, they pay a fee in $SIGN.
The Result: This prevents "verification spam" and ensures that every piece of data anchored to the blockchain has a cost associated with its integrity. In 2026, as millions of attestations move across chains like Ethereum, Solana, and TON, this creates a consistent, non-speculative demand for the token.
