02 · Why TRACE

Why TRACE

Built for regulated evidence.

Six primitives make TraceProtocol the default proof layer for enterprises handling high-value documents.

SHA-256 Hashing

Every document generates a unique cryptographic fingerprint. Any modification creates a different hash — tamper-evident by design.

Multi-Chain Support

Anchor proofs on EVM Layer-2 networks optimized for cost and latency. Linea, Polygon, BSC, Solana — pick the chain that fits your SLA.

Merkle Tree Batching

Gas-optimized attestation. Anchor thousands of documents in a single blockchain transaction.

API Integration

RESTful API, webhooks, and SDKs. Plug attestation into existing document pipelines without changing the files themselves.

Public Verification

Any third party can reproduce the proof. No account required — only the document hash or attestation ID.

FLEX Modules

Industry-ready configurations for banking, legal, healthcare, supply chain and more. Compliance scaffolding from day one.

How it works

From upload to immutable proof.

01
Upload Your Document
Documents stay with you. We only process a cryptographic hash — the file never leaves your control.
02
Generate SHA-256 Hash
A deterministic 64-character fingerprint uniquely identifies the exact bytes of your file.
03
Batch with Merkle Tree
Your hash is combined with others in a Merkle tree, producing a root that anchors the entire batch.
04
Blockchain Attestation
The Merkle root is written on-chain. You receive an attestation ID and a transaction hash to cite.
05
Verify Anytime
Any third party can reproduce the proof and confirm the document matches the on-chain record.
