nakatoshi

A Bitcoin Vanity Address generator.

nakatoshi accepts as input a "starts with" string to search for, and produces an 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

Cargo

$ cargo install nakatoshi

Manually

Download the latest released binary and add executable permissions:

```bash

Linux example:

$ wget -O nakatoshi "https://github.com/ndelvalle/nakatoshi/releases/download/v0.1.1/nakatoshi-linux-amd64" $ chmod +x nakatoshi ```

CLI information

``` nakatoshi 0.1.0 Bitcoin vanity address generator

USAGE: nakatoshi [FLAGS] [OPTIONS]

FLAGS: -b, --bech32 Use Bech32 addresses starting with bc1q (Lowercase address) -c, --case-sensitive Use case sensitive to match addresses -h, --help Prints help information -V, --version Prints version information

OPTIONS: -f, --file File with starts-with prefixes to generate addresses -s, --starts-with Start with prefix used to match addresses -t, --threads Number of threads to be used [default: The number of CPUs available on the current system] ```

Use examples:

Generate a vanity address (case sensitive)

shell nakatoshi 1ki

Generate a vanity address (case insensitive)

(Note: might be a bit faster since matching is less strict) shell nakatoshi 1ki -i

Use a file with multiple possible matches

A file with 1 pattern per newline can be used to search for vanity addresses. When for example you have a file called input.txt it would look like this: shell nakatoshi -f input.txt And running everything case insensitive would be: shell nakatoshi -f input.txt -i The contents of the file would look like: 1git 1hub 1etc

Search for a Bech32 address

shell nakatoshi -b bc1qki (Note: There is no need to search with the case-insensitive flag because bc1q addresses are 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, be sure to cargo run --release to get the best performance from the application.

Adding parameters in this context looks like cargo run --release -- -f somefile.txt -i
