//HTMF_PROTOCOL / SOFTWARE

The investigation engine behind Vant.

HTMF Protocol moves an investigation from blockchain visibility to a defensible conclusion. It qualifies what a flow of value is actually entitled to assert, keeps observation, hypothesis and conclusion apart, and keeps a pattern from quietly hardening into a fact.

//01 / not-another-graph-tool

Built to make an investigation defensible, beyond merely legible.

Most tools in this space show flows, display labels and produce risk scores. HTMF starts from a different premise: seeing a flow, understanding what it means, and earning the right to conclude something from it are three separate steps.

diff -- conventional_tools.vs.htmf
-show flows
+qualifies what a flow is entitled to mean
-display labels
+tests how much weight a label can actually carry
-produce risk scores
+separates confidence from proof
-generate reports
+projects a report from evidence already on record

//02 / how-htmf-thinks

Every case advances through the same controlled cycle.

engine.log
$ run investigation --focus=current
> Focus → Question → Evidence → Candidates → Finding → Challenge
> writing finding to case record...
> submitted to challenge layer

The engine sets its own focus and asks its own question, collecting evidence only once a question authorises it. Every finding it reaches is written to a single case record, then handed to a layer whose only job is to try to prove it wrong before it is allowed to stand.

//03 / the-vocabulary

Every statement carries one of five levels, and none is ever upgraded quietly.

levels.htmf
enum EvidenceLevel {
  OBSObservation  // a raw fact, read exactly as given
  HEUHeuristic   // a plausible reading, held provisionally
  DETDetermined  // explicit, reproducible method
  HYPHypothesis  // candidate explanation + alternatives
  OPEOperational  // qualified, actionable conclusion
}

A plausible pattern is reported at exactly the confidence it has earned. A hypothesis keeps its status until new evidence lifts it to a certainty. Every claim is reported at the level it earns, including the alternatives that were considered and rejected.

//04 / artificial-intelligence

AI makes the investigation faster. Certainty still has to be earned elsewhere.

HTMF separates three roles that most AI systems dangerously merge: a model that explores and proposes; a deterministic core that is the only part of the system allowed to establish a fact; and an adversarial layer whose sole purpose is to try to break every finding before it is allowed to stand.

A model's output is treated as a lead. It can shape a question or suggest a hypothesis immediately, earning evidentiary weight only once an independent, reproducible method confirms it.

[ Assistance earns its way to proof. Every finding meets its challenge. ]

//05 / built-for-hard-cases

The problems that break a naive trace are the problems HTMF is built around.

[x]Swaps and conversions
[x]Bridges across chains
[x]Mixers and pools
[x]Exchange deposits & on-chain limit
[x]Multi-chain flows
[x]Dilution after a break in continuity
[x]Operator vs beneficiary distinction
[x]Human-reviewed reporting

//06 / designed-to-be-reviewed

Every conclusion must be traceable, reproducible and challengeable to stand.

Every acquisition, calculation and decision behind a finding is recorded in a permanent, append-only forensic record, extended with every step. This keeps each conclusion reviewable, verifiable and defensible, preserving the integrity of the process throughout.

Vant’s software is built to support disciplined forensic work while preserving professional responsibility. Findings are produced through the system, reviewed through a structured process, and released only after authorised human validation. This ensures that every conclusion is both technically grounded and professionally accountable.

//07 / continuous-development

Built through continuous investigation work, always evolving beyond a static dataset.

HTMF Protocol is developed through the continuous analysis of real-world blockchain investigations.

Every week, our team replays and documents public and client-authorised cases, expanding the software’s knowledge of transaction patterns, services, protocols and investigative scenarios.

This growing evidence base enables the system to recognise increasingly complex behaviours, improve investigative coverage and support more consistent forensic reasoning over time.

Rather than relying on static datasets, the platform evolves through structured, reproducible investigation work performed by experienced analysts.

HTMF changes the role of software in blockchain investigation: from displaying traces to governing what can be safely concluded from them.

A blockchain record becomes evidence only through interpretation and verification.

It has to be interpreted, structured, verified and reviewed.

The gap

Digital asset crime has created a new evidentiary gap.

Blockchain transactions are often public, yet usability is a separate matter entirely. Law enforcement, legal teams and regulated institutions need more than raw blockchain data.

They need structured reasoning, verified flows, clear source references and evidence that another party can review. Vant exists to reduce that gap.

Public, yet complex

A visible transaction is a starting point. It has to be interpreted and connected to an investigative narrative before it becomes a conclusion.

Expert dependence

Police and legal teams too often depend on a handful of external specialists to read what the chain is saying.

Reproducibility gap

Reports can be hard to reproduce, leaving another reviewer to guess how a conclusion was reached.

What we build

A reproducible framework, built to be verified.

Vant develops investigation infrastructure for digital asset cases: software and methods that reconstruct asset movements, identify relevant paths, separate confirmed facts from hypotheses, and produce structured material for legal, law enforcement and compliance work.

The objective is to equip investigators with a framework they can verify, challenge and use.

Architecture

HTMF Protocolarchitecture
HTMF Protocol architecture: Victoria the investigation orchestrator at the centre, connected to four specialist chips (H Hierarchical Analyst, T Transactional Analyst, M Metric Analyst, F Framework Analyst), the HTMF Protocol deterministic authority below, and Input/Context and Output panels at the base.

One orchestrator, four specialists, one deterministic authority. Victoria coordinates the investigation; HTMF Protocol is the only part of the system allowed to establish a fact.

Vision

The future of blockchain evidence.

For decades, financial investigations were built around institutions, accounts, documents and jurisdictions. Digital assets have changed that environment.

Before · today · tomorrow

01
The world before
Institution-led financial systems

Financial investigations traditionally took place within relatively bounded systems.

Investigators could request bank records, review company structures, examine contracts and reconstruct financial movements through regulated institutions and identifiable intermediaries.

The evidence was often difficult to obtain, but the systems, responsibilities and investigative procedures were broadly understood.

02
The world today
Hybrid financial infrastructure

Financial activity now moves across bank accounts, payment providers, exchanges, wallets, stablecoins, bridges and blockchain protocols.

A single movement of value may pass through both traditional and decentralised infrastructure within minutes, creating an investigative environment that is public in parts, private in others, and fragmented across multiple systems.

The real challenge lies in connecting on-chain and off-chain information, interpreting complex transaction structures and transforming them into evidence that institutions can independently understand and verify.

03
The world tomorrow
A core institutional capability

As tokenised assets, stablecoins and blockchain-based settlement become integrated into mainstream finance, the distinction between traditional finance and digital assets will become increasingly less relevant.

Banks, exchanges, regulators, law-enforcement agencies and other institutions will need the ability to investigate financial movements across both environments with consistency, transparency and evidential discipline.

Institutions will need this capability. The real question is what investigative standard they will choose to trust.

The real challenge is turning blockchain data into reproducible, reviewable evidence.

The next step

The justice system needs investigation logic that goes beyond risk indicators.

Existing tools have helped the industry detect risk, visualise flows and identify known entities. That work is useful. But the next challenge is different.

Institutions need documented reasoning, source transactions, explainable paths, visible uncertainty and conclusions that another investigator can review. This is the future Vant is building for.

Why HTMF

A protocol built for reproducible investigation.

HTMF Protocol is designed for a world where blockchain investigations must be reproducible, reviewable and institutionally useful: a transparent methodology in place of a black-box risk score.

It is an investigative framework that preserves source transactions, documents reasoning steps, separates verified facts from hypotheses and supports human review.

Computational sovereignty

Investigation capability is becoming a question of sovereignty.

As financial and criminal intelligence work comes to depend on automated systems, a strategic question sits behind every technical one: who controls the capability to investigate, whose infrastructure it runs on, and whether its reasoning can be inspected rather than simply trusted.

For European institutions, relying on foreign, proprietary black-box platforms to investigate matters of public and national interest is itself a form of exposure, not only a procurement choice.

Vant is built as European infrastructure: hosted within the EU, governed by a methodology that can be inspected rather than taken on faith, and producing findings that do not depend on a single external vendor's continued cooperation.

HTMF Protocol is the first expression of that approach, applied to blockchain evidence today. The same discipline, reproducible reasoning, a transparent method, and findings a human can review, extends naturally as investigative work expands beyond a single data source.

Frequently asked

What is computational sovereignty in financial intelligence?

Computational sovereignty is the principle that institutions should retain direct control over the methodology, infrastructure and reasoning used to investigate financial and criminal activity, rather than depending on an external, proprietary black-box platform. In practice, this means the investigative method can be inspected, the infrastructure is hosted within the jurisdiction it serves, and the resulting findings do not depend on a single vendor's continued cooperation.

How does Vant apply computational sovereignty?

Vant applies this principle through the HTMF Protocol, a deterministic investigation engine hosted as European infrastructure and built so its reasoning can be reviewed and its findings reproduced independently, rather than trusted as an opaque score.

The bridge

Vant exists to build the bridge between blockchain activity, investigative reasoning, legal evidence and institutional action.

HTMF Protocol

A method designed to be reproducible.

HTMF is built around a simple principle: an investigation should be reproducible. Every relevant step should be traceable back to source transactions, addresses, amounts and explicit investigative decisions.

What is the HTMF Protocol?

The HTMF Protocol is Vant's deterministic investigation engine for blockchain and digital asset evidence. It reconstructs transaction paths from source transactions, separates confirmed facts from investigative hypotheses, and produces structured, reproducible findings that a human investigator can review and challenge before they are allowed to stand.

How is HTMF Protocol different from a blockchain risk score?

Rather than assigning a single opaque risk score, HTMF Protocol documents the reasoning behind each conclusion at one of five defined evidence levels, from raw observation to qualified operational finding, so that another investigator, legal reviewer or institutional partner can retrace exactly how a conclusion was reached.

How the protocol works

01
Start from source transactions
The protocol begins from the source transactions of a case, before any name, label or score enters the picture.
02
Reconstruct transaction paths
It follows the relevant paths that assets take across the chain, step by step.
03
Preserve the record
Transaction identifiers, addresses, amounts and timestamps are preserved at every step.
04
Separate fact from hypothesis
Confirmed movements are held apart from investigative assumptions, and both stay visible.
05
Apply caution rules
Where a step is uncertain, the engine treats it conservatively rather than overstating it.
06
Stop at meaningful signals
It recognises endpoints and structures such as exchanges, mixers and bridges.
07
Produce investigation logs
Each decision is documented so the reasoning behind a conclusion can be reviewed.
08
Support human validation
Investigators confirm, challenge and enrich the results, and verified cases feed a growing reference base.

Another investigator, legal reviewer or institutional partner should be able to retrace how a conclusion was reached.

The engine

Question-driven by design.

The engine starts from the questions an investigation must answer, then resolves each one against the evidence, going well beyond simply surfacing patterns in the data.

This keeps the investigation legible: every path exists because a question required it, and every conclusion carries the reasoning that produced it.

Trust & deployment

Built for controlled, auditable environments.

Vant is designed with institutional deployment in mind. Our infrastructure strategy prioritises security, controlled access, auditability and European data governance.

Infrastructure strategy

Security and governance, by design.

European data governance
A European approach to how data is handled and stored.
Northern-European hosting
Infrastructure located within the European Union.
Controlled access
Access scoped to the people and roles that need it.
Audit trail
Actions recorded so work can be reviewed after the fact.
Data separation
Case data kept separated by design.
Institutional deployment
Deployment models suited to legal and law enforcement settings.

A measured commitment

As the platform develops, our objective is to support deployment models suitable for legal, compliance and law enforcement environments. We describe direction here, and keep our promises deliberately modest.

Investigation integrity

Reproducible, reviewable, auditable.

Our process is designed to preserve the evidence and the reasoning behind every step, keeping investigation results fully accountable rather than black-box outputs.

What we preserve

The evidence behind every conclusion.

Source transactions
The origin points every path is built from.
Transaction identifiers
Verifiable txids for each movement.
Wallet addresses
The addresses involved at each step.
Timestamps and amounts
When a movement occurred, and how much moved.
Reasoning steps
The investigative decisions behind each conclusion.
Fact and hypothesis
Held apart, and clearly labelled throughout.
Hash integrity
Records protected against silent change.
Human review
Checked against manually validated cases.

Continuous validation

Built through daily testing, benchmarking and case validation.

Vant is developed through a continuous feedback loop between real investigations, manually validated benchmarks and software-driven analysis. Our team tests the engine every day, challenges its outputs, documents edge cases and strengthens the reference base used to improve future investigations.

This approach combines human expertise, deterministic forensic logic and machine-learning-assisted development to make the system more reliable, more auditable and more effective over time.

Where uncertainty exists, it must be visible. Where a conclusion is confirmed, the underlying evidence must be reviewable.

For institutions

Built for the institutions that must respond.

Law enforcement, legal teams, compliance departments and public institutions each need blockchain evidence they can understand, verify and act upon.

Law enforcement

Vant provides structured investigation material that helps officers understand blockchain movements, identify relevant paths and communicate technical findings clearly.

Legal teams

Vant helps convert complex blockchain activity into structured evidence packages that support complaints, legal analysis, recovery efforts and communication with authorities or platforms.

Compliance & platforms

Vant supports the analysis of suspicious flows, victim-linked deposits, scam-related infrastructure and transaction patterns that require deeper investigative context.

Public institutions

Vant contributes to a broader objective: strengthening society's ability to respond to financial crime involving digital assets.

Research & benchmarks

A measurable, improving framework.

Vant is building a reference base of verified investigations, and testing the engine against it rather than making promises about it.

Testing against reality

We test the engine against validated cases.

By comparing software-generated results with manually validated cases and publicly documented investigations, we continuously test the reliability, coverage and limitations of our investigative engine.

Each verified case sharpens the reference base, and each comparison shows us where the method holds and where it needs work.

The goal is a measurable, reviewable and improving investigation framework, honest about its own limits.

Reliability

How consistently the engine reproduces conclusions that hold up under review.

Coverage

The range of cases, chains and structures the method can address.

Limitations

Where the method is uncertain, stated openly rather than hidden.
