peercoin / peercoin-address-generator

A secure, minimal client-side Peercoin address generator.

Peercoin Address Generator

This is the source-code of paperwallet.peercoin.net, a secure client-side peercoin address generator.

It was built from ground up aiming for performance on mobile devices, but you can also use it on desktop browsers.

Building locally

If you're concerned about generating your addresses online, there is always the option of building the project locally. The steps to do that are listed bellow:

0. Make sure you have Node installed.
1. Clone this repo;
2. In the project folder, run npm install;
3. Then run npm start.
4. Open localhost:3333 in your browser and generate your wallet.

Running wallet via docker - Instructions

1. Clone this repo locally on master branch and run build instructions;
2. Clone this repo on server on docker branch;
3. Copy /public content from local to /public folder on docker branch you cloned in server;
4. Run: docker build -t ppc-wallet .;
5. Run: docker run --name ppc-wallet-nginx --restart on-failure -p 5001:80 ppc-wallet.

The Reverse-proxy and SSL files are located on local NGINX (outside of docker). They can be found at: /etc/nginx/sites-available/default.

SSL is generated by Let's Encrypt via certbot.

The URLs addressed are:

https://hodl.peercoin.net/ https://paperwallet.peercoin.net/

In order to update SSL certificate, run the command below:

sudo systemctl stop nginx && sudo certbot certonly --standalone -d hodl.peercoin.net -d paperwallet.peercoin.net && sudo systemctl start nginx

The configuration used at /etc/nginx/sites-available/default is:

# Peercoin Wallet configs

upstream ppc-wallet-generator {
  server 127.0.0.1:5001;
}

server {
  listen 80;
  server_name hodl.peercoin.net paperwallet.peercoin.net;
  
  location / {
    proxy_pass http://ppc-wallet-generator;
  }

  listen 443 ssl;
  ssl_certificate /etc/letsencrypt/live/hodl.peercoin.net/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/hodl.peercoin.net/privkey.pem;
  include /etc/nginx/conf.d/ssl.conf;
}

peercoin-address-generator's Issues

Some variables(?) are left in the About view

Created in 2012, it's been running for more than <b>{{timeAlive()}} years</b> with considerably less energy than pure PoW cryptocurrencies such as Bitcoin. Along those {{timeAlive()}} years Peercoin also never had any type involvement with pre-mining, fraudulent ICOs or any critical security breaches.

Add BIP38 encryption/decription support

Useful for more secure addresses.

It never yields anything but a blank screen on bulk generation

Tested on mobile with same results.

Add Bulk Generation option

Users should be able to generate multiple wallets at once.

BIP32 support

Wallet should have HD wallet mode.

Testnet support

Testnet support would help with testing.

Make it a full PWA

We need some stuff in order to make it run fully offline/"native" (PWA):

• Add manifest.json;
• Add app icons (android/iOS sizes);
• Setup theme colors (Android);
• Setup splash screen image (iOS)
• Add service-worker.js

Add paperwallet art

Issue created to discuss paperwallet art.

Add QR Code for private key

As of today only public key shows a QR Code.

Update project bundler

At the time of conception of this project, Brunch was used as bundler. But now it's prime time has since past and the project is not so active anymore, which leads to bugs hard to solve, and features that never come making projects based on it hard to mantain. Small community also doesn't helps with it's survival rate.

The main two options for replacement today are:

• Webpack
• Rollup

Both are rocking for years now and have super active community and plugins support. Webpack feels more like a cannon to kill a fly, since it's so full of features. Rollup is like a light fast car that delivers what it needs to.

We should discuss here which one to use for this project.

My vote goes for Rollup, since I already use it extensively, and since I'm basically the only front-end dev here who cares, if no one else gets involved we will eventually pick it up.

Everyone is more than welcome to argue.

Add i18n support

We need internationalization in order to get more users.

Show version in about view

Show pubkey after generating the keypair as well.

It's useful in some scenarios. For example when you need pubkey quick for multisig contract or something.

Add favicon

App needs favicon.
