Bitmain is blocking protocol upgrades to preserve their mining advantage.
This is quite distinct from someone taking advantage of a visibly broken
and highly toxic smart contract to net themselves tens of millions of
dollars. Further, Bitmain is performing a patented hardware optimization.
The patents mean that other miners are unable to capitalize on these
optimizations. These optimizations are to the tune of 30%. If you give one
player in the mining industry a permanent 30% cost advantage they will
eventually own everything. It's an industry where margins tend towards zero.
The asicboost patent is a direct threat to the health of the Bitcoin
ecosystem, and now we have visible proof. The war against segwit and the
strife with Bitcoin Unlimited was very damaging to the ecosystem, damaging
to the price, and holding back significant improvements and upgrades to the
Bitcoin protocol. I interpret this as a direct attack on the Bitcoin
ecosystem.
I don't know if changing the rules to nullify asicboost is the right move.
I'm sure this won't be the last patent that causes damage to the ecosystem.
But you need to recognize that the issue is not that Bitmain ran a hardware
optimization. It's that hardware optimizations exist which directly inhibit
upgrading the protocol. And it's that hardware optimizations exist
encumbered by patents enough to give one party a decisive advantage in
mining, decisive enough for them to build a single, centralized monopoly.
Each problem is separate, and each problem is significant, and each problem
is fundamental. The DAO attack was a one-time bout of stupidity that
threatened a fixed amount of money. asicboost is an ongoing status that
directly damages Bitcoin's ability to upgrade, and directly damage
Bitcoin's ability to retain any modicum of decentralization in the
hashrate. The DAO issue did neither of these things for ethereum.
