Blockchain Encoding

Sealbound can encode your certificates on the blockchain, creating a permanent and tamper-proof record of each certificate.

What Does Blockchain Encoding Mean?

When a certificate is encoded on the blockchain:

• A unique digital record is created for each certificate
• This record is stored on a public blockchain network
• Anyone can verify the certificate's authenticity without contacting the issuer
• The record cannot be altered or deleted

How It Works

1. You enable blockchain encoding when creating an order
2. Certificates are issued to your recipients as usual
3. Blockchain records are created automatically after issuance
4. Recipients can connect a wallet to receive the on-chain version of their certificate

What Gets Stored on the Blockchain?

Only certificate metadata is stored on the blockchain — not personal data. This includes:

• A unique certificate identifier
• The issuing organization
• The date of issuance
• A verification hash

No personal information (names, emails, etc.) is stored on the blockchain.

Verification

Anyone with a certificate's verification link or QR code can check its authenticity. The verification page shows:

• Whether the certificate is valid
• When it was issued
• Who issued it
• The blockchain transaction record (if encoded)

Do I Need Blockchain Encoding?

Blockchain encoding is optional. It adds an extra layer of trust and verifiability, but standard certificates are still valid and verifiable through the platform.

Consider blockchain encoding when:

• You need certificates to be verifiable independently of the platform
• Recipients value having a tamper-proof digital record
• You want to provide the highest level of certificate authenticity
