Trust & receipts

Trust the mechanism, not the claim.

SYGNL states how evidence was checked, locks campaign rules and leaves a record after selection.

01 · Evidence

How every check is classified.

The classification says what happened. It does not inflate one source into a broader claim.

01

Proved

Wallet signature

A cryptographic action proved control at that moment.

02

Imported

Discord account

A provider supplied the account fact to SYGNL.

03

Attested

X action

The participant supplied evidence; it is not independent verification.

04

Reviewed

Submitted answer

A person recorded a judgement against the declared requirement.

02 · Chain of custody

What locks, and when.

Rules, participant evidence, review decisions and the final allocation each lock at a different, explicit point.

Useful context. Deliberate boundaries.

The same campaign can be legible to every role without giving every role the same data.

05 · Non-claims

What SYGNL does not claim.

Credibility starts with naming the edges of the mechanism as carefully as its strengths.

  1. 01

    Attested does not mean independently verified.

  2. 02

    Fit does not guarantee selection.

  3. 03

    A provider outage is not evidence failure.

  4. 04

    Group rules are not described as one flat equal-odds draw.

  5. 05

    Human review is not mathematically reproducible.

  6. 06

    SYGNL does not use black-box ML to decide access.
