A peer-to-peer status feed with posts unlocked by Lightning.

Squeaknode allows you to create, view, buy, and sell squeaks.

A squeak is an immutable, signed structure that:
* contains up to 280 utf-8 characters of text, encrypted (can only be decrypted with access to the decryption key obtained by lightning payment)
* contains the height and block hash of the latest bitcoin block
* contains the public key of the author
* contains the public key of the recipient, if the text is end-to-end encrypted
* contains the hash of another squeak, if the squeak is a reply
* can be used to derive a unique hash

The protocol is defined [here](https://github.com/yzernik/squeak/blob/master/docs/PROTOCOL.md).


## Installation

### Requirements
* a Bitcoin node
* an LND node
* Python 3.6 or later

#### Optional
* a Tor SOCKS5 proxy (you can open Tor Browser and run it in the background)

### Step 1. Create the configuration
> Create a **config.ini** file and fill in the relevant sections to connect to your Bitcoin node and LND node:

```
[node]
network=mainnet

[lightning]
backend=lnd
lnd_tls_cert_path=~/.lnd/tls.cert
lnd_macaroon_path=~/.lnd/data/chain/bitcoin/mainnet/admin.macaroon

[bitcoin]
rpc_host=localhost
rpc_port=8332
rpc_user=devuser
rpc_pass=devpass

[tor]
proxy_ip=localhost
proxy_port=9150

[webadmin]
enabled=true
username=devuser
password=devpass
```

If you want to use [c-lightning](https://github.com/ElementsProject/lightning) as the Lightning Network node backend instead of [LND](https://github.com/lightningnetwork/lnd), replace the `lightning` section with the following:

```
[lightning]
backend=clightning
clightning_rpc_file=~/.lightning/lightning-rpc
```

Add any other [configs](docs/configuration.md) that you need.

### Step 2. Install squeaknode:

```
pip install squeaknode
```

Or install from source

```
python3 -m venv venv
source venv/bin/activate
pip install .
```

### Step 3. Start squeaknode:

```
squeaknode --config config.ini
```

Go to http://localhost:12994/ and use the username/password in **config.ini** to log in.

## Test

### Unit tests:

#### Requirements
* tox

```
make test
```

### Integration tests:

#### Requirements
* docker-compose
* jq

```
make itest
```
