S4CHAIN

Secure • Transparent • Immutable • Verified

Next-generation blockchain-based academic credentials system

What is S4CHAIN?

S4CHAIN stands for Secure • Transparent • Immutable • Verified — a blockchain-based platform that revolutionizes how academic credentials are issued, managed, and verified.

Secure

Cryptographically secured credentials that cannot be forged or altered

Transparent

Open ledger system where all transactions are publicly verifiable

Immutable

Once issued, certificates are permanently recorded on the blockchain

Verified

Instant verification by employers, institutes, and institutions

How It Works

1

Institution Registration

Educational institutions register on S4CHAIN through the Central Authority portal, providing their details and obtaining a verified address on the blockchain.

2

Certificate Issuance

Institutions issue digital certificates for completed courses or degrees. Each certificate is cryptographically signed and stored on the Polygon blockchain.

3

Blockchain Storage

Certificates are immutably stored on the Polygon network, making them permanently accessible and impossible to forge or revoke without proper authorization.

4

Public Verification

Employers, other institutions, or anyone can instantly verify the authenticity of a certificate by querying the blockchain.
