Ethereum Classic

Ethereum Classic is a hard fork of Ethereum, following the DAO hack of 2016. Ethereum Classic supporters focus on the idea of "immutability", or principle that the blockchain should not be changed.

I'm fine with Ethereum Classic existing. I'm just saying that I'm not interested in putting my own effort toward it.

We demonstrated how you can profitably attack a $2 billion cryptocurrency network like Ethereum Classic with as little as $1.5 million, and how you can "bankrupt it" with $55 million, netting +$1B in profit.

Ethereum Classic has <1% of Ethereum Project's hashing power, and, while there are plenty of sellers, no one's buying.

Antibailout Ethereum Classic gets its first exchange support: …

Hopefully, other exchanges do the ethical thing, too.

Crypto is down overall, but I'm getting really bullish on Ethereum Classic. Why?

* Scripting language of ETH
* Economics like BTC

And the big one for ETC:

* Institutional investors evaluating "fundamentals" will love how it leverages the best features from the top two coins.

Just bought ETC/ETH β€” long Ethereum Classic, short ETH.

Ethereum Classic should pivot their engineering effort towards zk-SNARKs and everything that screams privacy and immutability. Ramping up innovations and giving projects a reason to build with a β€œClassic first” approach will have long-term impact.

Ethereum Classic is what happens when original developers and a whole community decide to leave an old chain to die on the side of the road. Instead, it survived and came back with a vengeance. It’s inspiring, really.

Be careful with coins that are not dominant in their respective mining algorithm, especially ones that are NiceHash-able. ETC has less than 5% of the total Ethash hash rate and is 98% NiceHash-able. 1-hr attack costs $5k. Almost $500k has been double spent.

[The successful 51% attack on ETC] is a significant setback, but I think ETC still has a unique positioning as a PoW + Turing-complete network with an active community, with sound principles. The question is whether a recovery in the medium or long term is plausible or if the network, unless it grows significantly, is perpetually vulnerable, therefore unusable.

I think that continuing to build the stack as planned (a secure PoW base layer, with layer 2 sidechains, plus developer tools, continuous efficiency gains, and adding of new features in the long term) will get ETC closer to the long-term vision of a blockchain perfectly suitable for secure decentralized computing.

Ethereum Classic experienced a 51% attack, with very large reorgs. There are also rumors of double spends.

A deep reorg is a rewrite of the blockchain, a rewriting of history. As such, it marks complete failure of immutability.

Since immutability is ETC's main claim to fame, this is technically a catastrophic failure.

Ethereum Classic is the worst of both Bitcoin and Ethereum.

Not as secure and immutable as Bitcoin, nor as aggressive as Ethereum in making the platform valuable for development.

I can’t find a single interesting project building on ETC. Not one.

ETC was the best thing to ever happen to Ethereum. It let us shed a lot of dead weight, so we can get back to work building a censorship-resistant global state machine.
