Transaction Graph Dataset for the Bitcoin Blockchain - Part 1 of 4

This dataset contains bitcoin transfer transactions extracted from the Bitcoin Mainnet blockchain.

Part2 is available at https://zenodo.org/deposit/7157854
Part3 is available at https://zenodo.org/deposit/7158133
Part4 is available at https://zenodo.org/deposit/7158328

Details of the datasets are given below:

FILENAME FORMAT:

The filenames have the following format:

btc-tx-<start blockno>-<end blockno>-<part>.bz2 

where <start blockno> is the starting block number, <end blockno> final block number, and <part> is the split part of the file. 

For example file btc-tx-100000-149999-aa.bz2  and the rest of the parts if any contain transactions from 

block 100000 to block 149999  inclusive. 

The files are compressed with bzip2. They can be uncompressed using command bunzip2.

TRANSACTION FORMAT:

Each line in a file corresponds to a transaction. The transaction has the following format:

<SYMBOL> <blockno> <txno> <from> <to> <value> 

<SYMBOL>  Type of transaction (i.e. BTC-IN or BTC-OUT).

<blockno>  Number of the block which contains the transaction. 

<txno>  Position of the transaction in the block (i.e. transaction number in the block).

<from>  Source bitcoin address/transaction of the transfer.

<to>  Destination bitcoin address/transaction of the transfer.

<value>  Amount of transfer.

BLOCK TIME FORMAT:

The block time file has the following format:

<block no> <timestamp>

<block no>  Number of the block. 

<timestamp>  Unix timestamp at which the block is mined as a hexadecimal number.
