For SMEs, ensuring the authenticity and integrity of key documents—such as contracts, quality certificates, patents, diplomas, or compliance reports—is vital for building credibility with customers, partners, and regulators. Traditional methods often rely on paper-based systems or centralized digital archives, both of which are vulnerable to forgery, alteration, and data loss.
Blockchain-based digital document certification provides a modern solution by storing a cryptographic proof of a document on an immutable, time-stamped ledger. Rather than placing the document itself on-chain, the system generates a unique digital fingerprint (a cryptographic hash) that is recorded on the blockchain. At any point in the future, the same document can be hashed again, and if the resulting fingerprint matches the blockchain record, the authenticity of the file is instantly verified.
How SAHEL Adds Value
With the SAHEL token, SMEs can easily access and scale document certification services. SAHEL can be used to:
-
Pay for Certification Services – SMEs use SAHEL to register new document hashes on the blockchain at minimal cost.
-
Incentivize Verification – External auditors, partners, or customers can be rewarded in SAHEL for validating or accessing document authenticity, creating trust loops within the ecosystem.
-
Standardize Processes Across Businesses – Because SAHEL is designed for SMEs, multiple organizations in a supply chain or consortium can use the same token to manage certification costs, creating a unified system for document verification.
How It Works in Practice
A quality certificate for an artisanal product is generated by an SME. The system computes the certificate’s hash and records it on the Solana blockchain, paying the transaction fee in SAHEL. The certificate itself contains a QR code linking to a verification portal. When a retailer or customer scans the code, the system checks the document against the blockchain record. The SME could also choose to reward users with small amounts of SAHEL for scanning and validating certificates, encouraging wider adoption of the verification process.
Technical Implementation Steps
- Platform Selection – Deploy certification services on Solana for fast and inexpensive registration, with payments in SAHEL.
- Document Hashing – Generate a SHA-256 hash of the document; store only the hash and metadata on-chain.
- On-Chain Registration – Record the hash, timestamp, issuer’s signature, and metadata via a smart contract.
- Verification Interface – Build a portal or mobile app where third parties can check authenticity by uploading or scanning documents.
- Privacy Measures – Keep the document itself in secure off-chain storage (IPFS, encrypted cloud, or enterprise servers).
- ERP/CRM Integration – Automate document certification during normal business operations, with fees settled in SAHEL.
- Security Controls – Safeguard private keys with hardware wallets or multi-signature accounts to prevent misuse.
Example Implementation
A training SME issues course completion diplomas to its clients. After each course, the diploma PDF is hashed, and the hash is registered on Solana with the transaction fee paid in SAHEL. The diploma includes a QR code linking to a public verification portal. When an employer reviews a candidate’s diploma, they scan the code and instantly confirm its authenticity. As part of their customer engagement strategy, the SME also distributes a small amount of SAHEL to graduates who verify their diplomas, encouraging them to explore the ecosystem further.
Benefits for SMEs
- Tamper-Proof Records – Immutable blockchain entries make alterations impossible without detection.
- Instant Verification – Third parties can confirm authenticity in seconds without contacting the issuer.
- Cost Efficiency – Low transaction fees in SAHEL make certification affordable even for smaller businesses.
- Ecosystem Engagement – Using SAHEL for payments and incentives integrates SMEs into a wider blockchain economy.
- Long-Term Integrity – Permanent timestamps ensure records remain verifiable years into the future.
