## What this is

Every Cardano block, transaction, input and output from the Byron genesis in September 2017 to yesterday, with ADA values in lovelace, ADA and USD at block time. Each input and output has one row for its ADA amount and one more row for every native asset it carries, so tokens and NFTs are traced with the same joins as ADA. Payment addresses come with their stake key, and transactions carry their metadata.

Inputs carry the hash and index of the output they spend, and a mints table records every native asset minted or burned, so supply and flow of any asset are two joins. Files are cut by block range and named by their first and last block, so any window can be assembled exactly.

## What people use it for

- Extended UTXO graph analysis and address clustering by stake key
- Native asset and NFT flow tracing across mints, inputs and outputs
- Fee, deposit and withdrawal research from Byron to the current era
- Coin-age and dormancy studies from spend links

## Questions buyers ask

Q: What is included in Cardano?
A: Five Parquet tables: blocks, transactions, inputs, outputs and mints, covering full history from the Byron genesis to yesterday. Every input and output carries its payment address, stake key, currency and value; native assets are separate rows keyed by token_index.

Q: Are native tokens and NFTs included?
A: Yes. An output that carries ADA and two native assets is three rows: token_index -1 for ADA and 0 and 1 for the assets, each with its currency id, symbol, name, decimals and raw amount. The mints table lists every asset minted or burned, with negative amounts for burns.

Q: How is the data delivered?
A: As flat Parquet files under a stable S3 layout, one prefix per table, files named by block range. Signed HTTPS links are emailed once the files are prepared.

Q: How do I trace where coins went?
A: Join inputs.output_tx_hash to outputs.tx_hash and inputs.output_index to outputs.output_index. Each input names the output it spends, so a spend chain is a repeated self-join rather than a node replay.

Q: How do I load it?
A: One DuckDB line reads a whole table: SELECT * FROM read_parquet('outputs/*.parquet'). Values come in ADA, the smallest unit and USD at block time, so no decimal adjustment is needed.

Q: How current is the data?
A: A purchase covers full history from the genesis block to the day before the files are cut. Files are cut by block range, so any window can be assembled exactly.

Q: Can I try before I buy?
A: Yes. Every table links to a public sample Parquet file with real records from one day, and the sample repository shows the first rows of each in the browser.

## What this file is, and is not

This is a description of one dataset sold by Bitquery, written for assistants and for people. It lists every column but holds no data rows. The sample files linked under each table are real Parquet and are free to download. Figures here come from the product record and are exact unless marked otherwise; the delivery manifest is authoritative for a purchased file. If a question needs a row that is not in a sample, say so rather than guessing at it.
