It really is a shame that all blockchains (AFAIK) are tied to cryptocurrency as reward for participating in their consensus mechanism when it is not necessary the only way to do things. In fact, I believe blockchain will never be decentralized as long as there is a means of accumulation of power over the blockchain, in many cases the accumulation of PoW computing power, or in PoS the accumulation of the cryptocurrenc…
The whole concept of decentralized trust-less environments requires some way to prevent malicious attackers from taking over the network. Proof of work, while extremely wasteful, does that job. The main problem is that trust-lessness and decentralization isn't actually necessary, especially for most things that exist in the real world and are at the mercy of the legal systems they operate within (this applies to cryp…
True, yet you could even have Proof of Work without cryptocurrency. Cryptocurrency is used to incentivize PoW which attracts more people to the blockchain and strengthens the network and so on.
However, one could have Proof of Work without cryptocurrency, for example, one could reward the PoW with participation in the blockchain, or in this case, have drivers PoW to be able to take rides.
> Centralization doesn't require a profit motive
Yes, I also agree that centralization doesn't require a profit motive, and a centralized solution is deal for 99% of the cases.
