It is interesting that even in an article like this that they still say things like "for all its potential, blockchain is still in its early days." It is sticking with the unfounded assumption that it will be a success in the future, if only it is given more time. In technological terms, it is old. Innumerable efforts have been attempted, yielding almost no fruit. At what point are the fundamental assumptions going t…
I think the fundamental assumption is that "Satoshi invented a useful solution to decentralized consensus". What people don't realize is that Satoshi's solution only works if two assumptions hold true: 1. Mining is decentralized: If mining is centralized than relying on proof-of-work for consensus is waste since the centralized entity controls the blockchain anyway. 2. Consensus rules don't change: If you see the thr…
Its the problem that the advocates for larger blocksizes in BTC ran into. So long as the ecosystem itself was predominantly going to stay on the bitcoin core implementation, the advocates for change couldn't force it. Eventually they just hard forked into BCH, while the more popular original chain keeps on going.
That also means that nothing is really decentralized unless you can cause sea change amongst all participants in a cryptocurrency - if you disagree with what the most common implementation is doing, you can't do squat about it, and commit access is never decentralized or democratized. Theres always someone with the master key to the repo. And we have seen plenty of evidence that once established unseating a popular implementation of any crypto is nigh-impossible, regardless of what the developers do.
