Ledger Attestation Governance
AICE records selected professional milestones on a distributed ledger to enable long-term verification. This page explains what is recorded, what is protected, and how the verification process works.
What is Recorded
The following information is written to the distributed ledger for eligible certificates:
- A cryptographic hash of the certificate (not the certificate itself)
- Domain of professional competency (e.g., Healthcare, Technology)
- Achievement level (e.g., Expert, Advanced)
- Timestamp of attestation
- Chain identifier for verification routing
What is NOT Recorded
The following information is never written to the distributed ledger:
- Personal names or identifiers
- Email addresses or contact information
- Assessment scores or detailed results
- Learning content or course materials
- Payment or financial information
- Any biometric or identity verification data
Privacy by Design
The attestation hash cannot be reverse-engineered to reveal personal information. Only the certificate holder can link their verified credential to the ledger record.
Eligibility Rules
Not all certificates qualify for ledger attestation. Eligibility is determined by:
Domain
Only selected professional domains are enabled for attestation. Domains are added based on regulatory relevance and verification utility.
Level
Each domain has a minimum level threshold (typically Expert or Advanced). Lower-level achievements are not attested to the ledger.
Assessment Type
Self-assessments and unverified assessments are excluded. Only formally assessed and verified competencies qualify.
Governance Decision
AICE reserves the right to suspend or revise attestation policies based on governance review or regulatory guidance.
Verification Process
Anyone can verify a ledger-attested credential using the following process:
- 1
Obtain the certificate number
The certificate holder shares their certificate number or QR code.
- 2
Search the AICE registry
Use the AICE verification page to look up the certificate by its number.
- 3
View ledger attestation status
If attested, the verification page displays the attestation hash and ledger reference.
- 4
Independent verification (optional)
Advanced users can verify the hash directly on the Polygon blockchain using the provided reference.
Limitations & Disclaimers
- Ledger attestation does not replace statutory licensing or professional registration requirements.
- Attestation confirms a learning milestone was achieved; it does not guarantee current competency.
- The system is designed for long-term verification, but blockchain technology carries inherent risks.
- AICE is not responsible for third-party interpretation of attested credentials.
- Attestation cannot be revoked once written, but certificates can be flagged in the AICE registry.
