dump-bitcoin-transactions

Generates a chronological list of all transactions summarizing each input, output and value transferred. This way of summarizing transactions is useful to test other systems using real world data from the bitcoin network.

Requires node.js with npm and uses the bitcoin-core module. I found the module not well documented so I added some bitcoin-core module examples.

Theory of Operation

Using data from an indexed full bitcoin node, start at block 0 and summarize each transaction, one per line of JSON, exposing all the transaction IDs and indexes of all inputs and outputs as well as associated values. Each line of the output is a complete JSON string in the form:

{
  "ins":[
    "<transaction-id>-<index>",
    "<transaction-id>-<index>",
    ...
  ],
  "outs":[
    ["<transaction-id>-<index>","<value>"],
    ["<transaction-id>-<index>","<value>"],
    ...
  ]
}

Coinbase transactions come from the imaginary transaction id / index:

0000000000000000000000000000000000000000000000000000000000000000-0

Sample Output

First 100M Rows

Here's links to gzipped files of the first 100M bitcoin transactions.

Setup

Install all the dependancies:

npm install

Set environment variables to point to the RPC service of a fullly indexed bitcoin node.

export RPCHOST="127.0.0.1"
export RPCPORT=8332,
export RPCNETWORK="mainnet"
export RPCUSERNAME="rpcuser"
export RPCPASSWORD="<your-password-here>"

Usage

Run the app and capture the results from STDOUT.

node app > transactions.txt

Optionally, you can add a starting block number. To start at block 100,000:

node app 100000 > transactions.txt
