# Example Use Cases

vBase provides tools for creating **globally credible, timestamped records** of data, models, and research outputs.

Any dataset or model that can be represented as a file or binary object can be **stamped** and later **verified**.

This page outlines common applications across both **financial** and **non-financial** domains.

## 1. Financial Applications

Verifiable data provenance is especially valuable in finance, where credibility disappears when timestamps or revision histories are unclear.

To demonstrate investment skill or dataset quality, recipients must see a complete and timely record that is free from selective presentation. vBase resolves long-standing inefficiencies in how financial data is marketed, evaluated, and consumed.

### 1.1 Alternative Data Providers

Stamp datasets that update daily or intraday — such as sentiment, macro indicators, investment scores, developer activity, or mobility data.

> **Purpose**: Create a **point-in-time audit trail** proving that historical data is complete, point-in-time, unaltered, and free from selective presentation.

**Example Workflow**

1. Generate a new dataset file each day.
2. Stamp the file immediately upon creation, assigning the Stamp to a Collection representing the dataset.
3. Share dataset with clients for verification against the blockchain-backed audit trails for the Collection.

### 1.2 Quant Researchers & Model Builders

Stamp each **portfolio weights file**, factor exposure, or signal output at every rebalance.

> **Purpose**: Establish a verifiable timeline of model behavior to prevent retrofitting or selective disclosure.

**Example**: A model builder stamps each rebalance file weekly, forming a continuous verifiable signal history.

### 1.3 Investment Managers

Create a verified record for fund sleeves, SMAs, or model portfolios.

> **Purpose**: Support compliant marketing and independent verification of reported performance.

**Example**: Clients can confirm that dashboards and disclosures reflect authentic point-in-time data that is live, out-of-sample, and free from selective presentation.

### 1.4 Fundamental Analysts

Stamp research models, valuation frameworks, or recommendation memos.

> **Purpose**: Document when each idea was generated and ensure analyses were not revised after outcomes were known.

### 1.5 Index Providers & Calculation Agents

Stamp methodologies, constituent files, and weights at each rebalance.

> **Purpose**: Produce an immutable audit trail of index construction, weights, and methodology versions.

**Use Case**: Common in benchmark governance and licensing workflows.

### 1.6 Time-Series & Forecasting Models

Stamp each model prediction, forecast, or signal batch.

> **Purpose**: Maintain a reproducible, timestamped record of model outputs across time.

### 1.7 Backtest Verification

Stamp configuration files and results when a backtest is executed.

> **Purpose**: Show when a backtest was run, with what parameters, and how many variants existed.

**Benefit**: Future performance from that date forward becomes verifiably *out-of-sample*.

### 1.8 Survey Data Providers

Stamp raw and aggregated responses.

> **Purpose**: Prove that survey results are authentic and point-in-time, not edited or re-weighted later.

### 1.9 Auditable Recordkeeping

Stamp recurring deliverables such as compliance, risk, or valuation reports.

> **Purpose**: Maintain a tamper-proof record of what was known and disclosed at each reporting interval.

## 2. Non-Financial Applications

vBase is domain-agnostic. Any field that produces data, content, or models over time can benefit from verifiable provenance.

### 2.1 AI & Machine Learning

Stamp training runs, prediction batches, or evaluation outputs.

> **Purpose**: Create a timestamped log of model behavior for auditability and reproducibility.

**Example**: Use Collections to record the evolution of a model across fine-tuning or retraining cycles.

### 2.2 Research & Academia

Register datasets, manuscripts, or experimental results.

> **Purpose**: Establish authorship, verify dataset inputs, and promote transparent research collaboration.

### 2.3 Media & Publishing

Stamp articles, images, or releases.

> **Purpose**: Prove publication time and authorship of original content.

**Use Case**: Useful for timestamping breaking news, original research, or official press materials.

### 2.4 Legal & Compliance

Anchor contracts, filings, or evidence to the blockchain.

> **Purpose**: Ensure that official documents can be proven unaltered since submission or disclosure.

### 2.5 Supply Chain & ESG Data

Stamp traceability updates, certifications, and ESG disclosures.

> **Purpose**: Demonstrate transparent provenance and accountability across suppliers and auditors.

### 2.6 Government & Public Agencies

Anchor datasets, forecasts, or policy releases.

> **Purpose**: Maintain verifiable public records and improve institutional trust.

### 2.7 Project & Client Deliverables

Stamp milestones, datasets, or deliverables at hand-off.

> **Purpose**: Create a shared, immutable record of project progress between teams and clients.

## 3. Summary

Whenever it is important to establish **what was known and when**, vBase provides a cryptographic, independently verifiable record.

It turns **data credibility** into a built-in property of your workflow.
