Special thanks to Vlad Zamfir for his work in developing many of the ideas behind prediction markets for content curation. For the past six years, people have been searching to try to find those elusive applications of blockchain technology that could finally break out into the mainstream. For cryptocurrency, the applications are largely already known – though it of course remains to be seen just how well it will be able to retain its advantages as traditional payment systems continue to become more efficient. But what about smart contracts and crypto 2.0? One route that we can take is to…

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…

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…

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…

Special thanks to Gavin Wood for prompting my interest into abstraction improvements, and Martin Becze, Vlad Zamfir and Dominic Williams for ongoing discussions. For a long time we have been public about our plans to continue improving the Ethereum protocol over time and our long development roadmap, learning from our mistakes that we either did not have the opportunity to fix in time for 1.0 or only realized after the fact. However, the Ethereum protocol development cycle has started up once again, with a Homestead release coming very soon, and us quietly starting to develop proof-of-concepts for the largest milestone…

Special thanks to Vlad Zamfir for introducing the idea of by-block consensus and convincing me of its merits, alongside many of the other core ideas of Casper, and to Vlad Zamfir and Greg Meredith for their continued work on the protocol In the last post in this series, we discussed one of the two flagship feature sets of Serenity: a heightened degree of abstraction that greatly increases the flexibility of the platform and takes a large step in moving Ethereum from “Bitcoin plus Turing-complete” to “general-purpose decentralized computation”. Now, let us turn our attention to the other flagship feature, and…

Now that Ethereum has launched and is rapidly nearing its Homestead phase, over the last few months we at the Ethereum Foundation have finally had the chance to have some breathing room and plan our strategies with a more long-term view. From a development perspective, we have now started in earnest the development of Serenity, the next large overhaul of the Ethereum protocol that will include powerful software abstraction features, the Casper consensus algorithm and hopefully some basic scaffolding that will allow for the development of scalability features over time with minimal disruption. POC1 has been released, and POC2 will…

If DEVCON1 proved anything in spades, it was certainly the enthusiasm, creativity, and momentum of the Ethereum developer community. Utilizing the never-before-seen potential unleashed by the Ethereum World Computer, our small-but-growing community is not just re-imagining money (or even just re-imagining the Internet)… It is also re-imagining and delivering alternative models for re-organizing the very fabric of our society around a more transparent and inspectable “stack”. ÐΞVgrants came into existence on April 7, 2015, in order to ease some of the natural burdens of developing the lower-level tools which will hopefully further the above scenario. At DEVCON1, I presented a…

The time is gone, the song is over, Thought I’d something more to say. — Pink Floyd It is with no small amount of sadness that I must bid ye farewell. Like The Floyd’s work, in the time I’ve been involved with Ethereum, I’ve sampled the full gamut of emotion. From the amazement of meeting so many cool people (not least of whom Jani and Wendell) in Miami, Jan ‘14, to meeting Jeff for the first time in Feb ‘14 for the first real face-to-face collaboration on a client, to travelling through the U.S. in March ‘14 and meeting luminaries…

Blockchains are a powerful technology, as regular readers of the blog already likely agree. They allow for a large number of interactions to be codified and carried out in a way that greatly increases reliability, removes business and political risks associated with the process being managed by a central entity, and reduces the need for trust. They create a platform on which applications from different companies and even of different types can run together, allowing for extremely efficient and seamless interaction, and leave an audit trail that anyone can check to make sure that everything is being processed correctly. However,…
