nakatoshi

A Bitcoin Vanity Address generator.

nakatoshi accepts as input a prefix string (Or a file with multiple prefixes) to search for and produce a Bitcoin address and private / public keys. The amount of time required to find a given pattern depends on how long the string is, the speed of your computer, and whether you get lucky.

Install

MacOS

$ brew tap ndelvalle/nakatoshi $ brew install nakatoshi

Cargo

$ cargo install nakatoshi

Manually

Download the latest released binary and add executable permissions:

OPTIONS: -i, --input-file File with prefixes to match addresses with -t, --threads Number of threads to be used [default: The number of CPUs available on the current system]

Examples:

Generate a vanity address

shell nakatoshi 1Kids

Generate a vanity address and parse JSON response

shell nakatoshi 1Bitc | jq

Use a file with multiple prefixes

A file with one address prefix on each newline can be used to search for a vanity address. This reduces the time to find a result.

Example:

shell nakatoshi --input-file input.txt

The contents of the input.txt file looks like this: 1Kids 1Love

Bech32 addresses

shell nakatoshi -b bc1qki

Note: There is no need to search with the case-sensitive flag because bc1q addresses are always lowercase.

Development

```shell

Build

$ cargo build

Help

$ cargo run -- -help ```

Note: Cargo run creates an unoptimized executable with debug info. When testing the speed/throughput of the application, make sure to use cargo run --release.
