Reading Byzantium’s Tea Leaves

Louis Rukeyser looks at the blockchain
I used to watch a television show called “Wall Street Week with Louis Rukeyser.” The host would frequently laugh at the way Alan Greenspan, the Chairman of the Federal Reserve, would testify in front of Congress. Rukeyser found it comical that we all had to “read the tea leaves” after Greenspan spoke. “I should warn you, if I turn out to be clear, you’ve probably misunderstood me.” ~Alan Greenspan Why did Mr.

Short Thoughts on Difficulty Calc

A short take
I found this text in EIP 2 of the Ethereum github repo. It’s from the justification section of the EIP. It explains some of the choices in the difficulty calculation code found here: The difficulty adjustment change conclusively solves a problem that the Ethereum protocol saw two months ago where an excessive number of miners were mining blocks that contain a timestamp equal to parent_timestamp + 1; this skewed the block time distribution, and so the current block time algorithm, which targets a median of 13 seconds, continued to target the same median but the mean started increasing.

Ethereum Block Production Continues to Slide

All the news that's fit to blog about
Two weeks ago, we wrote this Medium post in which we describe the slowdown in per-week block production due to the Ice Age or Ethereum Difficulty Bomb. We thought it would be interesting to continue to watch the process as it unfolds. We wondered “Is the difficulty bomb having its desired effect”? The following chart is the one we presented two weeks ago. It shows the number of blocks produced each week since the inception of the Ethereum chain (August, 2015).

Is the Ice Age Affecting Block Production?

This is just one of 100’s of questions we have about what is happening on the Ethereum blockchain. We’re developing TrueBlocks to help us answer these questions and more. TrueBlocks is a set of software libraries, applications, and command line tools that provide fast, easy, fully-decentralized access to the Ethereum blockchain data. As part of preparing for our next release, we’ve written a a number of simple command line tools to test our code.

Be Careful Little Brain What You Code

Never tell them who you are
When I was a kid, my mother used to send my brothers and me to vacation Bible school. Having children of my own, I’m pretty certain she did that to get rid of us for the summer. The experience had no lasting effect on me (thank God), but I remember a song we used to sing: Be careful little eyes what you see Be careful little eyes what you see

It’s Growing! It’s Growing!

Will it ever stop?
I spend much of my free time on the Ethereum Stack Exchange answering questions about Solidity and asking questions about the Ethereum data, so I’m well aware which questions are most frequently asked. By far, the most repeated question on that forum is how long it takes to sync the Ethereum blockchain using geth or Parity. The short answer to that question is It takes forever. But this is only a perception.

The Real Flippening

Getting to Ether
My wife constantly tells me we should sell our Ethereum holdings, and I constantly resist. She wants to buy a new sewing machine. I want to wait until “The Flippening.” What is “The Flippening”? Well, there’s an old biblical word “quickening” which refers to the moment an unborn infant first moves in its mother’s belly. I love that word, and when I first heard the word “flippening”, I thought of it.

Zero-Storage Data Publishing on Ethereum

Taking advantage of off-chain monitoring
What’s the cheapest way to publish data while maintaining an unchangeable, permanent record of having done so? Blockchain? What’s the most expensive way to do computing today? Blockchain? Actually this second point may or may not be true, but one thing is true, if the blockchain is expensive, storing data is the reason why. Any data. In this article we will recount our experience trying to create a simple one-way publisher-to-consumer data delivery smart contract.

DAO Token Holders’ Response (in Charts)

Created with TrueBlocks
I am posting this previously unpublished post now because I’m clearing out my drafts folder, and I didn’t want to simply delete the post. I wrote it soon after the DAO hack, but before it became apparent that the White Hats rescue the remaining ether in The DAO (or as some have called it “safely steal the ether”). The post is probably only interesting for historical reasons. References to days of the week in this post are to be read as meaning the week of Friday, June 17th.

A Eulogy for The DAO — Part II

Second in a series
Introduction In this second installment of a multi-part series of articles analyzing the nearly 170,000 interactions with “The DAO” smart contract, we discuss the contract’s “Creation Period.” Previously, we presented an overview of The DAO’s lifespan. In that overview, we identified four distinct timeframes: the Creation Period, the Operational Period, the Post-Hack Period, and the Recovery Period. In this installment, we focus our attention on the Creation Period. Future installments will analyze each of the remaining three periods separately.
