I understand the argument regarding power consumption. However, if we're going to green wash ( https://en.wikipedia.org/wiki/Greenwashing ) a cryptocurrency, we need to focus on more than power consumption. Given that power is getting cheaper and cleaner through solar[1, 2], this is asking people to further accumulate more waste and precious metals in the form of fixed drives. This is not eco-friendly and it's dubiou…

Praising solar and being concerned about accumulating wastes in the same sentence is pretty ironic imo.

There are already blockchains that do not require proof of work (Lisk, Nav, Dash, NEO, etc) and already storage based blockchains (Filecoin, Storj, Sia, Maidsafe, etc). It is unclear to me what Chia brings to the table that is really new.

Filecoin and sia are not proof of storage. They are both proof of work, in fact filecoin runs on Ethereum. Not sure about Storj or Maidsafe.

The storage based blockchains don't use storage space as a means of verification- they're storage product focused (you buy/rent/use/sell storage space on the platform as a commodity). That's not what Chia does; it seems like its primary use will be store of value/transactions like Bitcoin. It's the "green" alternative to BTC- I wouldn't call Filecoin, Storj, Sia, Maidsafe, etc. competitors to Bitcoin (and I don't thi…

I was confused. I thought chia was going to be also a storage mechanism. I was pointing out those coins that are built around the idea of storage.

That said, Filecoin does use some form of proof of storage:

I'm trying to understand... "The three best proofs of space rapidly the propagated through the whole network and proofs of time servers start working on top of them." Should that read, "The three best proofs of space rapidly propagate through..."?

... rapidly get propagated ...

There already is delegated prove of stake algorithms that solves the power consumption problem.

I have never understood what stops POS algorithms from being havens for opportunistic cheating. There is no punishment for spending energy on attacking the network unsuccessfully because you are still also playing good with the majority.

In POW schemes you can only use your mining power on a single chain; in POS it seems like you can "stake" every competing chain simultaneously.

You need the proof of replication to show that a storage contact is being fufilled, not to secure the chain of blocks. proof of replication could be adapted to protect the chain, but that's not how it works at the moment. At least as far as I can tell.

so this has been an issue that keeps coming up for a while, but i don't really understand the issue. * As others have asked, how much is bitcoin supposed to use? What's the right amount and why? How is that number better/worse than the amount of resources spent on existing financial infrastructure? * We are rapidly progressing towards an era of free (extremely cheap) clean power. Just today ( https://electrek.co/2017…

The problem is that with a competitive mining market, Bitcoin energy use will rise until the cost of mining a block is equal to the reward for that block (i.e. market equilibrium). So if the cost of energy goes down but the price of Bitcoin stays constant, the amount of energy expenditure will be (approximately) equal. Likewise, if the price of Bitcoin goes up, the amount of energy used will go up accordingly. The re…

I haven't seen the hashrate drop when the price drops. We may be more limited by supply of ASICs than the price of electricity.
