Ethereum Classic (ETC), regardless of what you may think of it, is not going away anytime soon. While it is no longer steadily rising, it has the hash power and marketcap to ensure enough people have an interest in keeping the thing going, and maybe even help it thrive.

What the hacker got away with is immaterial at this point.

Early on, things didn’t seem so secure. Most of the Ethereum community: miners, merchants and exchanges, seemed on board with the hardfork. Immediately after, media outlets called the fork a resounding success. Then, seemingly out of nowhere, Ethereum Classic emerged.


That is a bit of a misnomer. Classic never really emerged from anywhere. As the unmodified chain, it would be more accurate to say Core emerged from Classic. But Classic didn’t have the support, or critically, the hashing power to gain much attention. After a few Reddit announcements and a post literally titled a Declaration of Independence, it caught the ire of Ethereum Core supporters.

Chandler Guo, a well-known Ethereum Miner and an angel investor in cryptocurrency startups, initially pledged an attack on Ethereum Classic. Armed with nearly 100GH/s of hashing power, Guo promised a 51% attack on the rebellious chain.

That resulted in increased attention from the media and public for Ethereum Classic. Those who opposed a “censored” blockchain moved to support it and its network power soared. Soon after, Guo abandoned his support for Ethereum Core and announced that his hashing power (now over 100GH/s) would instead be used to support the unmodified chain.

What is unclear is why. Why did he plan to attack Ethereum Classic and why did he change his mind? We caught up with Guo, and put these questions to him.

Guo is Chinese and there was a bit of a language barrier, the first time we asked him why he originally opposed classic, he didn’t seem to understand the question, but eventually we got to it.

Ian DeMartino: At first you said you were going to attack Ethereum Classic, what went into your decision-making at that time?

Chandler Guo: Only one reason: Don’t do evil.
 I know the Ethereum Hardfork is wrong. [You shouldn’t] change a blockchain’s history.
 I hope to do the right thing. [People should] never change the blockchain.

[After some explaining that I am asking about his initial plan to attack Classic, not his later decision to defend it.]
