Myntcore

This is Under's fork of Bitpay's Bitcore that uses Myntoin 2.1.1 It has a limited segwit support.

It is HIGHLY recommended to use https://github.com/silence48/myntcore-deb to build and deploy packages for production use.

Getting Started

Deploying Myntore full-stack manually:

sudo apt-get update
sudo apt-get -y install curl git python3 make build-essential libzmq3-dev python2.7
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

#restart your shell/os

nvm install 10.5.0
nvm use 10.5.0

#install mongodb
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5
echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list
sudo apt-get update
sudo apt-get install -y mongodb-org
sudo systemctl enable mongod.service

#install myntcore
sudo ln -s /usr/bin/python2.7 /usr/bin/python
git clone https://github.com/silence48/myntcore.git
cd myntcore && git checkout lightweight
npm install -g --production

Copy the following into a file named myntcore-node.json and place it in ~/.myntcore/ (be sure to customize username values(without angle brackets<>) and/or ports)

{
  "network": "livenet",
  "port": 3001,
  "services": [
    "myntd",
    "web",
    "insight-api-mynt",
    "insight-ui-mynt"
  ],
  "allowedOriginRegexp": "^https://<yourdomain>\\.<yourTLD>$",
  "messageLog": "",
  "servicesConfig": {
    "web": {
      "disablePolling": true,
      "enableSocketRPC": false
    },
    "insight-ui-mynt": {
      "routePrefix": "",
      "apiPrefix": "api"
    },
    "insight-api-mynt": {
      "routePrefix": "api",
      "coinTicker" : "https://api.coinmarketcap.com/v1/ticker/myntcoin/?convert=USD",
      "coinShort": "MYNT",
	    "db": {
		  "host": "127.0.0.1",
		  "port": "27017",
		  "database": "mynt-api-livenet",
		  "user": "",
		  "password": ""
	  }
    },
    "myntd": {
      "sendTxLog": "/home/<yourusername>/.myntcore/pushtx.log",
      "spawn": {
        "datadir": "/home/<yourusername>/.myntcore/data",
        "exec": "/home/<yourusername>/myntcore/node_modules/myntcore-node/bin/myntd",
        "rpcqueue": 1000,
        "rpcport": 7774,
        "zmqpubrawtx": "tcp://127.0.0.1:28332",
        "zmqpubhashblock": "tcp://127.0.0.1:28332"
      }
    }
  }
}

Quick note on allowing socket.io from other services.

• If you would like to have a seperate services be able to query your api with live updates, remove the "allowedOriginRegexp": setting and change "disablePolling": to false.
• "enableSocketRPC" should remain false unless you can control who is connecting to your socket.io service.
• The allowed OriginRegexp does not follow standard regex rules. If you have a subdomain, the format would be(without angle brackets<>):

"allowedOriginRegexp": "^https://<yoursubdomain>\\.<yourdomain>\\.<yourTLD>$",

To setup unique mongo credentials:

mongo
>use mynt-api-livenet
>db.createUser( { user: "test", pwd: "test1234", roles: [ "readWrite" ] } )
>exit

(then add these unique credentials to your myntcore-node.json)

Copy the following into a file named mynt.conf and place it in ~/.myntcore/data

server=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
zmqpubrawtx=tcp://127.0.0.1:28332
zmqpubhashblock=tcp://127.0.0.1:28332
rpcport=7774
rpcallowip=127.0.0.1
rpcuser=myntcoin
rpcpassword=local321 #change to something unique
uacomment=myntcore-sl

mempoolexpiry=72 # Default 336
rpcworkqueue=1100
maxmempool=2000
dbcache=1000
maxtxfee=1.0
dbmaxfilesize=64

Launch your copy of myntcore:

myntcored

You can then view the Myntoin block explorer at the location: http://localhost:3001

Create an Nginx proxy to forward port 80 and 443(with a snakeoil ssl cert)traffic:

IMPORTANT: this "nginx-myntcore" config is not meant for production use see this guide here for production usage

sudo apt-get install -y nginx ssl-cert

copy the following into a file named "nginx-myntcore" and place it in /etc/nginx/sites-available/

server {
    listen 80;
    listen 443 ssl;
        
    include snippets/snakeoil.conf;
    root /home/myntcore/www;
    access_log /var/log/nginx/myntcore-access.log;
    error_log /var/log/nginx/myntcore-error.log;
    location / {
        proxy_pass http://127.0.0.1:3001;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        proxy_connect_timeout 10;
        proxy_send_timeout 10;
        proxy_read_timeout 100; # 100s is timeout of Cloudflare
        send_timeout 10;
    }
    location /robots.txt {
       add_header Content-Type text/plain;
       return 200 "User-agent: *\nallow: /\n";
    }
    location /myntcore-hostname.txt {
        alias /var/www/html/myntcore-hostname.txt;
    }
}

Then enable your site:

sudo ln -s /etc/nginx/sites-available/nginx-myntcore /etc/nginx/sites-enabled
sudo rm -f /etc/nginx/sites-enabled/default /etc/nginx/sites-available/default
sudo mkdir /etc/systemd/system/nginx.service.d
sudo printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" | sudo tee /etc/systemd/system/nginx.service.d/override.conf
sudo systemctl daemon-reload
sudo systemctl restart nginx

Upgrading Myntore full-stack manually:

• This will leave the local blockchain copy intact: Shutdown the myntcored application first, and backup your unique mynt.conf and myntcore-node.json

cd ~/
rm -rf .npm .node-gyp myntcore
rm .myntcore/data/mynt.conf .myntcore/myntcore-node.json

#reboot

git clone https://github.com/silence48/myntcore.git
cd myntcore && git checkout lightweight
npm install -g --production

(recreate your unique mynt.conf and myntcore-node.json)

• This will redownload a new blockchain copy: (Some updates may require you to reindex the blockchain data. If this is the case, redownloading the blockchain only takes 20 minutes) Shutdown the myntcored application first, and backup your unique mynt.conf and myntcore-node.json

cd ~/
rm -rf .npm .node-gyp myntcore
rm -rf .myntcore

#reboot

git clone https://github.com/silence48/myntcore.git
cd myntcore && git checkout lightweight
npm install -g --production

(recreate your unique mynt.conf and myntcore-node.json)

Undeploying Myntore full-stack manually:

nvm deactivate
nvm uninstall 10.5.0
rm -rf .npm .node-gyp myntcore
rm .myntcore/data/mynt.conf .myntcore/myntcore-node.json
mongo
>use mynt-api-livenet
>db.dropDatabase()
>exit
