Certificate Glossary.

Plain-language definitions of every term used in Digital Witness certificates — for legal teams, auditors, and anyone asked to read a certificate without a cryptography background.

File integrity

File Integrity Hash

What it is

A mathematical fingerprint created from the file at the moment it was captured.

What it represents

The fingerprint is unique to the exact contents of the file at that moment. If the file were altered in any way — even by a single pixel or character — the fingerprint would change completely.

How to think about it: Similar to checking a paper document against an original letter by letter. The fingerprint lets the system later determine whether the digital file is still identical to its original form.

SHA-256 Hash

What it is

The specific fingerprint value generated for the file.

What it represents

A long sequence of characters that corresponds only to this version of the file. If the file changes, the fingerprint no longer matches.

How to think about it: Comparable to a DNA profile: two different files cannot share the same fingerprint unless they are identical.

Witniumchain record

Block Information

What it is

Information about when the record was written into the permanent system log.

What it represents

Witniumchain uses QBFT consensus, meaning records are immediately final once confirmed. The chain state is additionally anchored to Ethereum daily, providing global verification.

How to think about it: Unlike proof-of-work chains where you wait for confirmations, QBFT provides immediate finality. After 24 hours your record is also verified on Ethereum.

Block Number

What it is

The position of the record within the chain.

What it represents

Higher numbers indicate newer entries. With QBFT, each block is final the moment it is added — no forks or reorganisations.

How to think about it: Like a page number in a chronologically ordered register where pages cannot be reordered or replaced.

Block Time

What it is

The recorded time at which the evidence was sealed.

What it represents

Marks the exact moment when the evidence became permanently fixed. QBFT validators must reach 2/3+1 consensus before a block is added.

How to think about it: Comparable to a notary's timestamp, but enforced by mathematical consensus rather than trust in any single authority.

Ethereum Anchor

What it is

A daily checkpoint of Witniumchain state committed to Ethereum mainnet.

What it represents

After 24 hours, your witness is secured both by the Witnium validator network and Ethereum. Tampering would require compromising both — computationally infeasible.

How to think about it: Like having your sealed document registered in both a private vault and a global public registry.

Cryptographic proof

Cryptographic Proof

What it is

A technical record that ties the file, time, and system state together.

What it represents

Demonstrates that this specific file existed in this specific form at a specific point in time.

How to think about it: Like a filing confirmation that shows what was submitted and when — created automatically, without manual handling.

Transaction Hash

What it is

A unique reference identifier for this record.

What it represents

Distinguishes this event from all others on the chain.

How to think about it: Comparable to a case number or tracking reference assigned when something is formally registered.

Smart contract

Smart Contract

What it is

An automated set of rules used to issue witness records.

What it represents

The rules governing how this certificate was created are predefined and not subject to discretionary change.

How to think about it: Comparable to a standardised form or statutory process that must be followed exactly, without individual interpretation.

Contract Address

What it is

The permanent identifier of the rule set used.

What it represents

Identifies which fixed rules were applied when this witness was issued.

How to think about it: Comparable to citing the exact regulation or policy under which a decision was made.

Cryptographically sealed data

Cryptographically Sealed Data

What it is

The data elements that were locked at the time of capture.

What it represents

These values describe the context, identity, and version of what was recorded. Any change would invalidate the seal.

How to think about it: Comparable to sealing a document in an envelope and signing across the flap — tampering would be visible.

Sealed Fields (workspace, user, file, version)

What it is

Identifiers describing who, what, and which version was recorded.

What it represents

Provide context and continuity, especially when multiple versions of the same material exist.

How to think about it: Like a case file reference that includes the client, matter, and document version.

Verification

Hash Verification

What it is

A repeatable integrity check.

What it represents

The same mathematical process can be applied later to confirm the data has not changed.

How to think about it: Comparable to comparing two photocopies line by line to ensure they are identical.

Data ID (SHA-256)

What it is

The fingerprint of the sealed data itself.

What it represents

Allows later confirmation that the sealed information remains unchanged.

How to think about it: A unique identifier that proves the sealed data hasn't been tampered with.

Cryptographic signature

Cryptographic Signature Verification

What it is

A digital approval mechanism.

What it represents

Shows that the data was approved by the correct system authority and has not been altered since.

How to think about it: Comparable to a handwritten signature that both identifies the signer and signals approval — enforced mathematically.

Ed25519 Signature

What it is

The specific digital signature format used.

What it represents

A modern, widely recognised cryptographic signature designed to be both secure and efficient.

How to think about it: A state-of-the-art signature method used by leading security systems worldwide.

Signature Valid

What it is

The verification status of the signature.

What it represents

Confirms that the data was approved by the correct signing authority, has not changed since approval, and the signature corresponds to the recorded public key.

How to think about it: Like having a notary confirm that the signature on a document is genuine and the document is unaltered.

Triple-layer protection

Triple-Layer Protection

What it is

Three independent protection mechanisms applied together.

What it represents

Integrity does not depend on a single safeguard. The layers are: digital signature (approval), data hash (modification detection), and Digital Witness seal on Witniumchain with daily Ethereum anchoring.

How to think about it: With QBFT consensus your record is immediately final. After 24 hours it's also anchored on Ethereum. Tampering would require compromising both networks — practically infeasible.

Witness identifiers

Witness ID

What it is

The identifier of the certificate itself.

What it represents

Distinguishes this witness from all others.

How to think about it: Like a unique case or reference number for this specific certificate.

Data ID

What it is

The identifier of the sealed data.

What it represents

Refers specifically to what was protected, not just the certificate.

How to think about it: Points to the actual evidence content that was sealed.

Timeline

What it is

A chronological view of the witness creation and subsequent system progression.

What it represents

Provides temporal context for when the evidence was sealed.

How to think about it: A history log showing when the evidence was captured and how the system has grown since then.

Capture location

Capture Location

What it is

Location data recorded at the time of capture.

What it represents

Indicates where the evidence was created, along with how precise the measurement was.

How to think about it: GPS coordinates that pinpoint the physical location, with accuracy information.

Environmental conditions

Environmental Conditions

What it is

Independent scientific data related to time and place.

What it represents

Information such as sun position and satellite availability supports the plausibility of the recorded time and location.

How to think about it: External data that independently corroborates when and where the evidence was captured.

AI forensic analysis

AI Forensic Analysis

What it is

An automated descriptive review of the content.

What it represents

Summarises visible features and quality but does not modify or replace the original evidence.

How to think about it: Comparable to an initial human observation note, generated automatically.

Quality Score

What it is

An automated estimate of clarity and usability.

What it represents

Helps readers understand how suitable the material may be for review or presentation.

How to think about it: A quick assessment of whether the evidence is clear enough to be useful.
