This is not a new observation or a universal property of crypto projects. Alternatives to POW, are an active subject of research, and are very important to several active crypto projects. You don't even have to look too far down the market-cap listings to find them.
- bumblebeard 9y agoWhat are some of them? I'm not too up on the latest research in this area so it would be interesting to know how you can do a cryptocurrency that doesn't depend on proof-of-work calculations.

- Frogolocalypse 9y agoThe issue with PoS is that it introduces trust into the element. There doesn't seem to be a way (yet?) where you can introduce PoS without lowering the security of new adopters.

- Frogolocalypse 9y agoPoS works on the premise that rewards will be given to holders. Unlike PoW, PoS has a single incentive structure where the management of the networks is aligned with the holders of the tokens. If you are not a large holder, the existing holders can re-write the rules to their advantage. You have to trust that large holders won't do this, even though the incentives align with that outcome.
