WEFOUNDHow to build a coin collection


We are going to create a digital token. Tokens in the Ethereum ecosystem can represent any fungible tradable good: coins, loyalty points, gold certificates, IOUs, in-game items, etc. Since all tokens implement some basic features in a standard way, this also means that your token will be instantly compatible with the Ethereum wallet and any other client or contract that uses the same standards.

So let's start with the basics. Open the Wallet app, go to the Contracts tab and then Deploy New Contract . On the Solidity Contract Source code text field, type the code below:

A mapping means an associative array, where you associate addresses with balances. The addresses are in the basic hexadecimal Ethereum format, while the balances are integers, ranging from 0 to 115 quattuorvigintillion. If you don't know how much a quattuorvigintillion is, it's many vigintillions more than anything you are planning to use your tokens for. The public keyword, means that this variable will be accessible by anyone on the blockchain, meaning all balances are public (as they need to be, in order for clients to display them).

We require a new digital currency (serving as a bonus point) that is developed as a plugin to be installed in wordpress platform where users can transact this currency in large or small units to one another from their dashboard.

* currency will not be connected to blockchain. it's not a decentralized global coin, its more like a members' rewarding or bonus point.

* value of internal currency (or bonus point) can be set manually in admin panel for users to know the worth when redeemed for a real price.

Build-a-Coin attempts to always produce correct code. If you haven't edited your code at all and have ruled out a build system misconfiguration, please email [email protected] with the following:

  • your coin's build-a-coin.txt or coin identifier
  • operating system version
  • compiler version
It is the policy of Build-a-Coin that if a coin compiles on our build platform (Debian/gcc), then it is working. Although Build-a-Coin coins should compile anywhere bitcoin can be compiled, we do not guarantee this.

If you put unreasonable values in, you'll get an unreasonable coin out. Build-a-Coin coins have been tested for correctness with reasonable inputs, but are not guaranteed to work. If you believe you've found a bug in Build-a-Coin itself, report it to [email protected] .

Build-a-Coin does not provide any support for the compilation process; there are many guides freely available that cover this topic.

The official source code for Coin 3D resides on Bibucket (https://bitbucket.org/). However, Wizzer Works has cloned this source to https://sourceforge.net/projects/coin3d/ in order to control the integrity of the software that works with Magic Lantern (version 3.1.3).

This section describes how to build Coin 3D for the Ubuntu 14.04 LTS operating system. There are three approaches that may be taken:

The first approach is strongly reccomended because it is based on the tar package distribution from the last official release, prior to moving the source to the open source community. The Wizzer Works code base also contains all the modifcations made to work with the Magic Lantern Inventor and Rehearsal Player tagets.

Coin collecting is a fun, safe, and rewarding way to interact with history and the world around you. Though it can be difficult to distinguish cheap, common currency from rare, uncirculated money, there are ways to make the process easier and less risky. Knowing where to find good coins, what to look for in a purchase, and how to keep your coins safe will help you start a collection with ease.
