# The [Bitcoin Message Tool](https://github.com/shadowy-pycoder/bitcoin_message_tool) in Go
A lightweight CLI tool for signing and verification of bitcoin messages. Bitcoin message is the most straightforward and natural way to prove ownership over a given address without revealing any confidential information.
This tool closely follows specification described in [BIP137](https://github.com/bitcoin/bips/blob/master/bip-0137.mediawiki)
## Installation
```shell
go install github.com/shadowy-pycoder/go-bitcoin-message-tool/cmd/bmt@latest
```
This will install the `bmt` binary to your `$GOPATH/bin` directory.
