How to build server less applications for Mist
Ethereum is not meant to be a platform to build esoteric smart contract applications that require a STEM degree to understand, but it aims to be one pillar of a different architecture for applications on the world wide web. With this post we will try to elucidate how this can be done and give some basic examples on how to start building a decentralized app. Who is this for? This text is intended at those who have a basic understanding of web technology and how to build a simple javascript and html app, and want to convert these skills into building apps for the Ethereum ecosystem. How can apps run without servers? Currently servers in web apps do much more than what they were originally…
Ethereum in practice part 3: how to build your own transparent bank on the blockchain
This is the third and final post on a series on how to use the Ethereum Wallet to create your own autonomous organisations. On the first post we detailed how to create a token, and on the second we shown how to generate a digital democracy controlled by these tokens. Now we will do the full circle and create a token controlled by the Organisation! We are going to modify the token contract to allow it to be minted by your DAO. So save the address of your current DAO in a note pad (pay attention to the icon) and grab this source code and you know the drill: contracts > deploy new contract > solidity source code > pick contract You can fill the parameters any way you want (yes, emojis are…
Ethereum in practice part 2: how to build a better democracy in under a 100 lines of code
This is a second post on a series on how to use the current Ethereum tools to build smart contracts without needing programming experience. Download the latest version of the Ethereum Wallet, read the first part and let's have fun! Creating a token is fun, but what is the value of a token that doesn't do anything new? We are now going to create a new contract that uses the tokens we just created. The contract will be a Democratic organization that lives on the blockchain and that anyone holding a share token will be able to vote on proposals. So let's go back to " Contracts " and then " Deploy Contract " and paste the DAO source code on the "Solidity Source" field. Choose the contract…
Ethereum in practice part 1: how to build your own cryptocurrency without touching a line of code
A lot of things have happened in the past few weeks in the Ethereum ecosystem, so many that it might be hard for a casual observer to understand where we are and what's available out there. So I would like to use my first post here to give you an overview of the tools we've built and how you can use them to build interesting things right now. But first a short introduction: I am Alex Van de Sande and I am the lead designer on the Ethereum foundation. At DevconOne I gave a talk entitled "The Blockchain Versus The Average User" where I went into more details on the challenges to bringing the Ethereum ecosystem to the aforementioned "Average User", one of which is the difficulty of defining…
