Silent risks that cost you
When a number can be changed unnoticed, both trust and money are at stake.
Forged invoices & documents
A figure on an invoice can be changed after issuance, and the original is hard to prove.
Opaque fund flows
Funds move through many steps with no single trusted log to reconcile against.
Backdated records
Customer and credit records can be edited and backdated as if nothing happened.
Simple in 3 steps
Enter information
You fill in the document info as usual — no crypto wallet or technical know-how needed.
Seal the proof
The system creates a “digital fingerprint” of the info and seals it on a public ledger.
Verify anytime
Later, just compare: if one character changed, the system instantly flags “altered”.
Pick your scenario
Three demos for the three most common problems. Click to try.
E-Invoice & Financial Document
Enter invoice metadata (number, tax ID, total, issue date). The system creates a keccak256 fingerprint and anchors it on the ledger. Alter any character to trigger a "Tamper detected" state, proving integrity.
Open toolFund Disbursal & Supply Chain
Trigger a multi-step workflow (Approved → Disbursed → Received) linked by a unique fund ID. Each state transition is written sequentially on-chain, forming an immutable audit trail.
Open toolCore KYC & Credit Profile
Submit a mock KYC/credit assessment profile. The system hashes the frozen profile state at that exact millisecond and registers it on-chain, preventing internal manipulation or retrospective backdating.
Open toolBlockchain in brief
A few foundations before you begin — no technical expertise required.
Types of blockchain
Public chain
Anyone can join, read and verify. Maximally transparent and decentralized — ideal for public proofs and digital assets.
Ethereum · Base · Solana · BNB Chain
Private / Consortium chain
Only permissioned members participate. High control and privacy — fit for internal or industry-wide enterprise processes.
Hyperledger Fabric · R3 Corda · akaChain
Hybrid model
Keep data private but seal its "fingerprint" on a public chain — discreet, yet backed by an open ledger’s trust.

Popular platforms & chains
🌍 Worldwide
🇻🇳 Vietnam
This sandbox uses a hybrid model: sealing private proofs onto a public chain (Base) — combining enterprise privacy with the trust of an open ledger.
Why you can trust it
Cannot be edited secretly
Proof lives on a distributed public ledger — no single person can delete or edit it.
Original data stays private
Only the “fingerprint” is public; your real content never leaves your hands.
Trusted timestamp
Each proof carries an objective timestamp, proving “who had what, and when”.
