title: Bitcoin dust transactions

description: <strong>General information</strong> This repository contains data regarding Bitcoin <em>dust</em> transactions. In the Bitcoin protocol, dust refers to the small amounts of currency that are lower than the fee required to spend them in a transaction. The repository comprises all transactions with at least one dust output or input. According to our definition, a dust output (or input) is considered dust if the associated amount is between 1 and 545 satoshis (where 1 satoshi = 10<sup>-8</sup> bitcoin). For more details about the definition of dust, see [1]. All dust transactions have been extracted from the first 479,970 blocks of the Bitcoin blockchain, thus covering the time period between January 3rd, 2009 18:15 GMT and August 10th, 2017 18:03 GMT. <strong>Data set description</strong> File Description txs A text file containing a representation of all Bitcoin transactions that create and consume dust. See the description below for more information about the structure of this file. txs_addr_map.csv A CSV file that maps numeric address identifiers to real Bitcoin addresses. This file comprises all addresses appearing in the txs data set. labels.csv A CSV file containing categorical entity labels for Bitcoin addresses appeared in transactions between 2010 and 2018. This file has been derived from the <em>Entity-Address data set</em> [2, 3] (see also: https://github.com/Maru92/EntityAddressBitcoin). outputs_spent_stats.csv A CSV file containing statistics about all spent outputs in the first 479970 blocks of the Bitcoin blockchain. The file describes the durations of dust and non-dust outputs. The duration is defined as the difference between the height of the block where the output is spent and the height of the block where it was created. cluster_sizes_*.csv These CSV files contain information about clusters of addresses induced by Bitcoin transactions. They have been used for the clustering analysis presented in [4]. See this GitHub repository for more information. <strong>Transaction representation</strong> The <em>txs</em> file contains a textual representation of dust transactions in the Bitcoin blockchain. Each row of the file corresponds to a transaction and is represented as a sequence of fields <code>info:inputs:outputs</code> with the following meaning. The <code>info</code> section contains general information about the transaction. It is represented as a list of comma-separated fields, namely: <code>timestamp,blockId,txId,isCoinbase,fee,approxSize</code>. The meaning of the fields is the following: <code>timestamp</code> represents the Unix timestamp of the block containing the transaction. <code>blockId</code> represents the height of the block containing the transaction. <code>txId</code> is a numeric value that univocally identifies the transaction. <code>isCoinbase</code> is equal to 1 if the transaction is a coinbase transaction, 0 otherwise. <code>fee</code> denotes the transaction fee, expressed in satoshis (i.e., the smallest bitcoin denomination). <code>approximateSize</code> denotes the approximate size of the transaction (expressed in bytes). The <code>inputs</code> section contains a sequence of (0 or more) transaction inputs separated by a semicolon. Each input, in turn, is represented as a comma-separated string <code>addrId,amount,prevTxId,offset</code> where: <code>addrId</code> represents the numeric identifier of the spending address; <code>amount</code> is the amount of value associated with the input (expressed in satoshis); <code>prevTxId</code> represents the numeric identifier of the transaction that created the output that is currently being spent; <code>offset</code> represents the position, among all outputs of <code>prevTxId</code>, of the output that is currently being spent.<br> The <code>outputs</code> section contains a sequence of (1 or more) transaction outputs separated by a semicolon. Each output, in turn, is represented as a comma-separated string <code>addrId,amount,scriptType</code> where:<br> <code>addrId</code> represents the numeric identifier of the receiving address; <code>amount</code> is the amount of value associated with the output (expressed in satoshis); <code>scriptType</code> is a numeric identifier representing the type of the script associated with the output (i.e., 0=UNKNOWN; 1=P2PK; 2=P2PKH; 3=P2SH; 4=RETURN; 5=EMPTY). <strong>Data analysis</strong> Data included in this repository have been employed for the analyses presented in [4, 5].
