This commit implements bech32 format and segwit addressing like defined in Bitcoin implementation. A module called bech32 and another one called segwit have been created. These two modules offers the support for encoding and decoding of bech32 string in different formats. In final, 99% coverage for bech32 and 97% coverage for segwit. The document is enough for now. Added an article explaining how and why Bech32/Segwit were implemented in pure Erlang.

nostr
An implementation of nostr in pure Erlang using OTP stack with minimal dependencies. Here the list of features offered by this application:
-
A library defined in module
nostrlib -
A client defined in module
nostr_client -
A relay defined in module
nostr_relay -
A common interface called
nostrto play with previously defined modules.
Disclamer
This project is in active development and cannot provide a stable application. This application should be used only for test at the moment.

Other Implementation (required by nostr)
- BIP-0340: Schnorr Signatures for secp256k1
- BIP-0173: Base32 address format for native v0-16 witness outputs
- BIP-0350: Bech32m format for v1+ witness addresses
Build
The code can be compiled using
rebar3 Erlang project manager.
$ rebar3 compile
Test
The current implementation is tested using
eunit and
common_test
both directly integrated with all default Erlang/OTP
release. cover is
enabled by default to have an idea of the coverage of the test. An
alias called check has been created to help using these tools.
$ rebar3 check
Documentation
A developer documentation is provided using
edoc and can be
generated on demand (automatically created if using rebar3 check
alias).
$ rebar3 edoc
This project has been created to explain how to create an Erlang/OTP
from scratch using only a release and few dependencies. The design
choices for the infrastructure, data-structures and algorithms can be
found in in notes directory. Those notes can be exported in
html, epub, pdf or plaintext using make.
$ make
The documents will be generated in _build/notes directory.
Development
For the developers, this project is using
asdf. The tools used are listed in
.tool-versions file. To bootstrap your system, install asdf and
just execute this command in the repository:
$ git clone https://github.com/erlang-punch/nostr
$ cd nostr
$ asdf install
