# Fact Sheets

A fact sheet is a summary document for one CMBI index series. Where a [methodology](/index-data/methodologies.md) document specifies how a series is constructed in full, a fact sheet is the short form: what the series measures, what it contains, and how it has behaved. It is the right starting point for evaluating whether a series fits a use case, and the methodology is where you go once it does.

Fact sheets are published as PDFs and refreshed periodically, so the document linked in each section below is always the current edition. Four of the CMBI series carry one.

## CMBI Single Asset Series

The CMBI Single Asset Series provide the cryptoasset community, investors and asset managers with publicly available and investable benchmarks that reliably and accurately track the price of a single cryptoasset, through sourcing market prices from numerous global liquidity venues. Indexes are designed to accurately reflect the performance of the global market, be easily tradable and be readily accessible to market participants.

## CMBI Multi Asset Series

The CMBI Multi Asset Series provide the cryptoasset community, investors and asset managers with publicly available and investable benchmarks that reliably and accurately track the value of cryptoasset markets. Indexes are designed and constructed leveraging Coin Metrics proprietary network and market data metrics and methodologies, including the Adjusted Free Float, CM Hourly Reference Rates and CM Real Time Reference Rates. Currently, CMBI Market Cap Weighted Products include the CMBI Bitcoin and Ethereum, CMBI 10 and CMBI 10 Excluding Bitcoin. Coin Metrics also administers the CMBI 10 Even which evenly weights the constituent assets of the CMBI 10 during the rebalance. Indexes are designed to accurately reflect the performance of the global market, be easily tradable and be readily accessible to market participants.

## CMBI Total Market Series

The CMBI Total Market Series provides users with publicly available and investable benchmarks that reliably and accurately track the value of cryptoasset markets that leverage the Datonomy to create Sector and Sub-Sector Indexes. The indexes are designed and constructed leveraging Coin Metrics proprietary network and market data metrics and methodologies, including the Estimated Market Capitalization, CM Hourly Reference Rates and CM Real Time Reference Rates. Currently, CMBI Total Market Series include the Total Market Index, eleven Sector Indexes, and three Sub-Sector Indexes. Indexes are designed to accurately reflect the performance of the global market, be easily tradable and be readily accessible to market participants.

## CMBI Mining Series

The CMBI Mining Series provide the cryptoasset community, investors and asset managers with publicly available and investable benchmarks that reliably and accurately track the activity of one of crypto's critical functions, mining. The CMBI Bitcoin Hash Rate (CMBIHASH) represents the implied hash rate that miners are contributing to Bitcoin at any single point in time. The CMBI Bitcoin Hash Rate utilize a 48hr lookback window to accurately reflect the current performance of miners whilst maintaining resistance to outlier results and potentially manipulative activities. The CMBI Bitcoin Observed Work (CMBIWORK) utilizes the real-time levels from the CMBI Bitcoin Hash Rate to represent an approximation for the number of hashes that have been conducted over the previous 24hr period.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gitbook-docs.coinmetrics.io/index-data/fact-sheets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
