# README

The backend node of Colla Network, a decentralized peer-to-peer communication and storage network.

Introduction

Colla Network is a decentralized peer-to-peer communication and storage network, Colla DApp (e.g. CollaChat) connects to Colla Network via selected Colla Node, there is no centralized storage and control of user data, user can specify which node or even easily setup own node(s) to connect to.

Build

Optimized Settings

It's recommended to optimize following settings before building your own executable file:

No	Package	File	Default Setting	Recommended Setting
1	[email protected]	multiplex.go	var MaxMessageSize = 1 << 20	var MaxMessageSize = 1 << 30
2	[email protected]	internal\net\massage_manager.go	var dhtReadMessageTimeout = 10 * time.Second	var dhtReadMessageTimeout = 300 * time.Second
3	[email protected]	network\network.go	const MessageSizeMax = 1 << 22	const MessageSizeMax = 1 << 30
4	[email protected]	msgio.go	defaultMaxSize = 8 * 1024 * 1024	defaultMaxSize = 1024 * 1024 * 1024

Installation

Get ready your server, domain and certificate first. You may rent a cloud server from CSP (or try on from a free instance), buy a domain or get a free one, use ACME to automatically issue & renew the free certificates from Let's Encrypt.

Tested OS

No	OS	Version and Spec.
1	Ubuntu	16.04/18.04/20.04, minimal 1vCPUs + 1GiB
2	Windows	Windows Server 2016

Linux

Download and uncompress

azureuser@myVM:~$ sudo wget https://github.com/curltech/go-colla-node/releases/download/v0.0.2/go-colla-node-linux-0.0.2.tar.gz
azureuser@myVM:~$ sudo tar zxvf go-colla-node-linux-0.0.2.tar.gz

Configure and run

azureuser@myVM:~$ cd go-colla-node
azureuser@myVM:~/go-colla-node$ vi conf/peer1.yml
azureuser@myVM:~/go-colla-node$ ./main (or ./main -appname peer1)

Use custom node in Colla DApp (e.g. CollaChat)

azureuser@myVM:~/go-colla-node$ sqlite3 peer1.db
sqlite> select discoveryaddress from blc_myselfpeer;
/dns4/peer1.curltech.cc/tcp/5720/wss/p2p/12D3KooWNwQ9pHZzmfjk8rZp4a1k5gXhibKxZMBdkdg1mTJEAYse
