I'm a great believer in judging the present through the knowledge of the past. In the past 25 or so years one of the biggest trends in business and technology was what might loosely be termed as the open source revolution. The notion of it being good b...

Although the core concept was proven last summer when lead developers Vitalik Buterin, Gavin Wood, and Jeffrey Wilcke initiated the PoC (proof-of-concept) series in Python, C++, and Go, a lot of engineering effort has gone to solidifying these implemen...

Ethereum has been preparing what we consider to be the most exciting digital alliance since IBM and Microsoft partnered so successfully on the IBM PC. We know that you’ve been anticipating great things from Ethereum and we are delighted to present you ...

Hello, fellow Ethereans. I am Mihai Alisie, one of the Ethereum founders, and for the past year I’ve served as the vice president of the Ethereum Foundation and as director of Ethereum Switzerland. In the early days of the project I concentrated my at...

Hi, Jutta writing again – I initially introduced myself when we started the bounty program earlier this year and I’m happy to provide you with an update on what’s happening on the security side prior and throughout launch. We have had some high qualit...

Into the ether Hello, fellow Ethereans. I am Mihai Alisie, one of the Ethereum founders, and for the past year I’ve served as the Vice President of the Ethereum Foundation and Director of Ethereum Switzerland. In the early days of the project I conce...

So first some background. We’ve already covered a little about what to expect from Frontier in the Ethereum Launch Process blog post and Gav has given us a comprehensive overview of the state of the development effort. You can also read about some of t...

So I'm not sure if this kind of development methodology has ever been applied to such an extreme before so I figured I'd document it. In a nutshell, it's sort of like test-driven triplet-programming development. While speed-developing our alpha codeba...

I’m Vinay Gupta, the newly minted release coordinator for Ethereum. I’ve been working with the comms team on strategy, and have now come aboard to help smooth the release process (some of the content in this blog is out of date, please see this link fo...

I was woken by Vitalik's call at 5:55 this morning; pitch black outside, nighttime was still upon us. Nonetheless, it was time to leave and this week had best start on the right foot. The 25-minute walk in darkness from the Zug-based headquarters to t...

One of the issues inherent in many kinds of consensus architectures is that although they can be made to be robust against attackers or collusions up to a certain size, if an attacker gets large enough they are still, fundamentally, exploitable. If att...

Special thanks to Andrew Miller for coming up with this attack, and to Zack Hess, Vlad Zamfir and Paul Sztorc for discussion and responses One of the more interesting surprises in cryptoeconomics in recent weeks came from an attack on SchellingCoin co...

Warning: this post contains crazy ideas. Myself describing a crazy idea should NOT be construed as implying that (i) I am certain that the idea is correct/viable, (ii) I have an even >50% probability estimate that the idea is correct/viable, or that (i...

Special thanks to Vlad Zamfir and Jae Kwon for many of the ideas described in this post Aside from the primary debate around weak subjectivity, one of the important secondary arguments raised against proof of stake is the issue that proof of stake alg...

Back in November, we created a quick survey for the Ethereum community to help us gauge how we're doing, what can be improved, and how best we can engage with you all as we move forward towards the genesis block release in March. We feel it's very impo...

First of all, happy new year! What a year it has been. With a little luck we'll surpass last year with an even more awesome year. It's been too long since I've given an update on my side of things and that of the Go team and mostly due to a lack...

One of the criticisms that many people have made about the current direction of the cryptocurrency space is the increasing amount of fragmentation that we are seeing. What was earlier perhaps a more tightly bound community centered around developing th...

The crypto 2.0 industry has been making strong progress in the past year developing blockchain technology, including the formalization and in some cases realization of proof of stake designs like Slasher and DPOS, various forms of

Hi, I’m Jutta! As some of you might have read in earlier posts, I’ve recently been busy setting up a security audit prior to the Ethereum genesis block release. Ethereum will launch following a world-class review by experts in IT security, cryptography...

OK so a minor update about what we are (and are not) doing here at Ethereum DEV. We are, first and foremost, developing a robust quasi-Turing-complete blockchain. This is known as Ethereum. Aside from having quasi-Turing-completeness, it delivers on a...

Time for another update! So quite a bit has happened following ÐΞVcon-0, our internal developer's conference. The conference itself was a great time to get all the developers together and really get to know each other, dissipate a lot of information (b...

Day 1 - Monday 24th Nov - ÐΞV: Mission and Processes The first day of ÐΞVcon-0 kicked off early at 7am with the Ethereum UK communications team arriving at the venue (Ethereum Dev UG’s workspace in Kreuzberg, Berlin) to set up the 4K high quality recor...

Yesterday was the first proper day of ÐΞVhub Berlin being open, following the first Ethereum internal developers' symposium ÐΞVcon-0. I want to post a few images to let you gauge the mood here. Henning, Marek, Viktor and Felix hacking on the couch ...

Proof of stake continues to be one of the most controversial discussions in the cryptocurrency space. Although the idea has many undeniable benefits, including efficiency, a larger security margin and future-proof immunity to hardware centralization co...

One of the latest ideas that has come to recently achieve some prominence in parts of the Bitcoin community is the line of thinking that has been described by both myself and others as "Bitcoin dominance maximalism" or just "Bitcoin maximalism" for sho...

I'm Gavin Wood, a co-founder of Ethereum and, along with Vitalik Buterin and Jeffrey Wilcke, one of the three directors of the Eth Dev, the NFP organisation that is managing the development (under contract from Ethereum Suisse) of the Ethereum blockcha...

Special thanks to Vlad Zamfir for much of the thinking behind multi-chain cryptoeconomic paradigms First off, a history lesson. In October 2013, when I was visiting Israel as part of my trip around the Bitcoin world, I came to know the core teams behi...

Special thanks to Robert Sams for the development of Seignorage Shares and insights regarding how to correctly value volatile coins in multi-currency systems Note: we are not planning on adding price stabilization to ether; our philosophy has always b...

Hi, I'm Stephan Tual, and I've been responsible for Ethereum's adoption and education since January as CCO. I'm also leading our UK ÐΞV hub, located at Co-Work in Putney (South West London). I feel really privileged to be able to lead the effort on the...

I thought it was about time I'd give an update on my side of things for those interested in knowing how we're doing on the Dutch side. My name is Jeff, a founder of Ethereum and one of the three directors (alongside Vitalik and Gavin) of Ethereum ÐΞV, ...
