Gav’s Ethereum ÐΞV Update V

Posted on March 2nd, 2015.

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 the train station was wet. Streetlights reflecting off the puddles on […]

The Subjectivity / Exploitability Tradeoff

Posted on February 14th, 2015.

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 attackers in a proof of work system have less than 25% of mining […]

The P + epsilon Attack

Posted on January 28th, 2015.

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 conceived by Andrew Miller earlier this month. Although it has always been understood that […]

Superrationality and DAOs

Posted on January 23rd, 2015.

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 (iii) “Ethereum” endorses any of this in any way. One of the common […]

Light Clients and Proof of Stake

Posted on January 10th, 2015.

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 algorithms are much harder to make light-client friendly. Whereas proof of work […]

Ethereum Community Survey

Posted on January 9th, 2015.

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 important to enable the community to interact with Ethereum […]

Jeff’s Ethereum ÐΞV Update II

Posted on January 6th, 2015.

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 of time. I’ve been so […]

On Silos

Posted on December 31st, 2014.

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 the common infrastructure of Bitcoin is now increasingly a collection of “silos”, discrete projects all working […]

Secret Sharing DAOs: The Other Crypto 2.0

Posted on December 26th, 2014.

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 scalable blockchain algorithms, blockchains using “leader-free consensus” mechanisms derived from traditional Byzantine fault tolerance theory, as well as economic […]

A call to all the bug bounty hunters out there…

Posted on December 18th, 2014.

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 and blockchain technology. Prior to the launch, we will also complete a bug bounty […]
