CCash

A webserver hosting a bank system for Minecraft

Description

the currency model most Minecraft Servers adopt if any, is resource based, usually diamonds, this model is fraught with issues however:

• the primary issue is minecraft worlds are infinite leading to hyper inflation as everyone accrues more diamonds
• there is no central authority minting the currency, any consumer can introduce more diamonds to the system
• some resources are passively reapable, making the generation of currency a larger focus then of products
• locality is required for transaction
• theft is possible, ownership is possession based

CCash solves these issues and adds a level of abstraction, the main philosophy of CCash is to have fast core operations that other services build on

Build

git clone --recurse-submodule https://github.com/EntireTwix/CCash/
mkdir build
cd build
cmake ..
make -j<threads>
sudo ./bank <admin password> <saving frequency in minutes> <threads>

Dependencies

• Parallel HashMap
• drogon web framework (and all its dependencies)

Features

Performance

• NOT written in Lua
• written in C++, arguably the fastest language
• multi-threaded
• parallel hashmaps a far superior HashMap implementation to the STD, that also benefit from multi-threaded
• Passwords are Hashed, allowing each user to be 12 bytes, which is allows hashmap to be flat

Safety

• Tamper Proof relative to an in-game implementation
• Auto-Saving, Saves on crash, Saves on close
• HTTPS (OpenSSL)

Accessibility

• Web front-end
• RESTful API for connected services like a market, gambling, or anything else you can think of
• able to be used millions of blocks away, across dimensions, servers, vanilla or modded. In contrast to an in-game modded implementation that would be range limited.

Connected Services

Go to {ip}/BankF/help to see the bank's methods. Using the Bank's API allows (you/others) to (make/use) connected services that utilize the bank, a couple ideas are

Implemented:

• a Leaderboard (ComputerCraft)

In-Dev:

• a Market

Ideas:

• Gambling
• Shipping
• High-level bank operations such as loans
• Some trust based system for transactions similiar to Paypal
• Cute frontend

**WARNING** : abruptly killing the program will result in data loss, use Close() method to close safely
