Let’s be clear about a few things stated here…

1. PoW blockchains are inherently unscalable and virtually all of them are centralized in that they are entirely operated by Chinese companies located mostly in China which outlaws cryptocurrencies for its citizens.

2. Anything that describes itself as a scalable blockchain is either not scalable or not a blockchain or a variant/compromise of PBFT or Anti-Sybil protections that are supposedly the core virtue of the platform

3. Blockchain-based applications, to date, have no successful applications that are in any way close to challenging non-blockchain-based platforms. Despite years of effort and billions of dollars of investment of money and talent. As Ms. Milic seems to imply in [1] by the use word “potential”.

4. Decentralization is nonsense. The proliferation of attempts (PoW, PoS, PoR, PoA, DPoS, PoET, SMR, BEAT, etc.) alone to achieve this in some credible form, and the current state, establishes this.

5. There is nothing in the way of transparency that a blockchain offers. In fact, quite the opposite: in most cases, it is entirely up to the particular implementation what is made transparent. For example, crypto-currencies rather famously keep the participants and their purposes intentionally indecipherable.

6. A reminder for point [5]: leaving beside the rather more involved probles, see my point 1. above in the most key of issues mentioned: “slow”

So, go ahead participate in the riot of money and misinformation in the space. But don’t be fooled. At least go in with eyes wide open. And see Peter Thiel’s recent remarks and some of my other writing on this subject.
