Byzantine Fault Tolerance, and its weaknesses in decentralised blockchains

The basic conclusion is that if you are rich enough, you may be able to subvert the system. Sure but that is exception. The current finical system, this is the norm.

A rich human wishing to subvert a decentralised blockchain network has a massive incentive to do so, and the resources to achieve it.

how? exactly? What could they do? Lets look at eth. There is 38 billion USD worth of Eth staked in the beaconchain. So first an attacker would need to acquire 1/3 of that amount of ether around 12.6 Billion. Someone could do that, but it would be hard to go unnoticed. Now what could they break? Well, they could censor transactions. That is it. With privacy preserving L2s this becomes imposable, since you wouldn’t be able to observe what is in a tx even.

Why decentralised blockchains can’t scale

Doesn’t address layers 2. L1 can’t scale and don’t need to.

Lets also take a look at the authors misunderstanding of NFTs. Which seem to equate NFT to the art things that have been popular lately. NFT have more use cases then that.
