Tags

Hash-in provenance timestamping. The file itself is never uploaded. Instead, only its SHA-256 hash and metadata. This is the 'notary' posture: spArxx.io keeps no copies of the original file, ever.

Balance and pricing reads. Lets a caller pre-check spend before an operation that costs spArks.

Public, unauthenticated certificate verification. Anyone can verify any spArxx.io timestamp proof.
