Certification creates deterministic verification artifacts for Gravity outputs. It is used when a customer needs a structured proof record, integrity hash, and human-readable certification package tied to an invoice ID.
What happens:
You select a tier, generate an invoice, send the required sats, and keep the invoice ID. After payment confirmation, Gravity generates the selected certification package and makes the output retrievable by invoice ID.
What you receive:
.cert.json — machine-readable certification record
.cert.sha256 — integrity hash
.cert.txt — readable certification summary
.cert.pdf — formatted human-readable report
T3 may include stronger archival / package-level verification artifacts
What happens:
You select a certification tier, generate an invoice, send the required sats, and keep the invoice ID. Once payment reaches Gravity’s confirmation threshold, Gravity generates deterministic certification artifacts tied to that invoice.
What you receive:
.cert.json — machine-readable certification record
.cert.sha256 — integrity hash
.cert.txt — readable certification summary
.cert.pdf — formatted human-readable report
Tier differences:
T1 — standard artifact validation for a single proof/output.
T2 — extended review with enhanced documentation and stronger evidentiary packaging.
T3 — maximum depth certification with archival assurance, strongest package structure, and highest verification confidence.
T1 — 400,000 sats
Standard certification for a single Gravity output or proof artifact
T2 — 1,000,000 sats
Extended certification with enhanced documentation and stronger evidence packaging
T3 — 2,000,000 sats
Maximum-depth certification with archival assurance and strongest verification package
