Individual audit trail records, or **Stamps**, can be grouped into **Collections**, allowing users to verify the history of an entire dataset, strategy, portfolio, or other body of work. Below are some common financial and non-financial applications. ## Financial applications Financial products are often evaluated by looking at historical data, predictions, or decisions. vBase helps make those histories independently verifiable. ### Alternative data providers Stamp dataset deliveries such as sentiment scores, macro indicators, developer activity, mobility data, or other predictive data to make them verifiably point-in-time. > **Purpose:** Create a point-in-time history that buyers can verify for evaluation and backtesting. **Example:** A provider stamps each daily delivery into a Collection. A client can later compare the dataset with the corresponding audit trail to verify the point-in-time integrity and completeness of the data. ### Trading strategies, signals & models Stamp trading signals, model forecasts, portfolio weights, or rebalance files as they are produced. > **Purpose:** Build a verifiable history showing what a model or strategy produced and by when. **Example:** A model builder stamps each weekly signal file in a Collection, creating a continuous point-in-time record that future investors can independently verify. ### Investment managers Create verifiable histories for model portfolios, fund sleeves, SMAs, or other investment strategies. > **Purpose:** Support independent substantiation of reported strategy or portfolio histories. **Example:** An investment manager stamps each portfolio update as it occurs. Investors can later compare reported historical positions or performance with the point-in-time record. ### Forecasts & research Stamp forecasts, recommendation histories, research models, valuation frameworks, or investment memos as they are produced. > **Purpose:** Document when predictions, recommendations, or research outputs existed and whether they were subsequently revised. **Example:** An analyst stamps each published recommendation into a Collection, creating a verifiable history that can later be evaluated against subsequent outcomes. ### Index providers & calculation agents Stamp index methodologies, constituent files, weights, and rebalance outputs. > **Purpose:** Create an independently verifiable history of index construction, constituent changes, weights, and methodology versions. **Example:** An index provider stamps each rebalance file and relevant methodology version, allowing future users to verify the index's recorded history. ### Backtests and live performance Stamp model specifications, configuration files, or backtest results before subsequent performance occurs. > **Purpose:** Document what research, parameters, or strategy definitions existed at a particular point in time and create a clear boundary between historical research and later forward performance. **Example:** A researcher stamps a model specification and backtest before beginning a live evaluation period. Later performance can then be assessed relative to the model definition that was recorded at the start of the period. ## Non-financial applications vBase is domain-agnostic. Any field that produces data, predictions, research, or other digital records over time can benefit from independently verifiable history. ### AI & machine learning Stamp model outputs, prediction batches, evaluation results, or model versions over time. > **Purpose:** Create a point-in-time history of model behavior for evaluation, auditability, and reproducibility. **Example:** A model developer uses a Collection to record successive evaluation outputs across model versions or retraining cycles. ### Research & academia Stamp datasets, manuscripts, experimental results, or research outputs. > **Purpose:** Document when research materials or results existed and create a verifiable history of subsequent revisions. **Example:** A research team stamps datasets and experimental outputs as they are produced, creating an independently verifiable record of the research process. ### Media & publishing Stamp articles, images, reports, press releases, or other original content. > **Purpose:** Document that specific content existed by a particular time and under a particular identity. **Example:** A publisher stamps an original research report before distribution, allowing its publication history to be independently verified later. ### Legal, compliance & recordkeeping Stamp contracts, filings, policies, risk reports, valuation reports, or other important records. > **Purpose:** Create an independently verifiable record of document integrity and timing. **Example:** An organization stamps recurring compliance or risk reports into a Collection, creating a point-in-time history of what was recorded at each reporting interval. ### Project & client deliverables Stamp datasets, analyses, reports, or other deliverables as they are completed or handed off. > **Purpose:** Create a shared, independently verifiable history of project outputs between teams, clients, or other counterparties. **Example:** A service provider stamps each major client deliverable into a Collection, creating a record of what was delivered and by when. ## Summary vBase can be useful anywhere historical data, predictions, or digital records need to be evaluated based on **what existed and by when**. The underlying content can remain private while its history becomes independently verifiable. ## Next steps * [Choose how to use vBase](/get-started/choose-how-to-use-vbase.md) * [How vBase works](/overview/how-vbase-works.md) * [Use the vBase web app](/get-started/web-app-overview.md) * [Python API quickstart](/get-started/api-py-quickstart.md)
