11 statements about Proof Of Stake, every show
Armstrong: Proof-of-stake blockchains are 99.9% more energy efficient than proof-of-work
“Ethereum and other blockchains use a new system called proof of stake, which is actually 99.9% more energy efficient.”
Weisbrot: Ethereum cut energy consumption by 99% switching to Proof of Stake
“Ethereum's migration from, ah, proof of work to proof of stake, ah, system where the energy consumption literally dropped by 99%, like, overnight”
Kahn: Proof of stake consensus reduces crypto energy consumption by 99%
“I mean, it's literally a 99% reduction. That's the, or those are the best estimates.”
Carlson-Wee: Mitigating 51% attacks is significantly easier in proof-of-stake networks
“The second thing is that if you attack a proof of stake network, mitigation of the attack after it happens is significantly easier. So if you, come in with, you know, 51% of the coins, and in, in most proof of stake, it's actually 34% of the coins is enough to…”
Dixon: Sub-second transaction finality is impossible in proof-of-work systems
“You just simply can't have, ah, like sub-second transaction finality in a proof of work system. Like, so Bitcoin, like you really need to wait, you know, each block is 10 minutes, and it has to do with the coordination among the network, and the network propag…”
Carlson-Wee: Almost every blockchain launching in 2019 uses proof-of-stake
“There's a reason that every, you know, I think 2017 was a major year of fundraising. And 2019 is a major year of launches, and there's a reason that every blockchain that's launching today is mostly using proof stake.”
Yahya: Proof of stake can theoretically match proof of work security
“Now the cost of actually participating in consensus and making the entire network work in real terms comes down dramatically. And it's just as secure, or at least theoretically can be made just as secure. And that's a controversial statement, but I will sort o…”
Dayan: Dark DAOs can bribe Proof-of-Stake validators to execute consensus attacks
“So what you can do with a dark DAO is start a staking pool where I say, like, you know, let me do my algorithmic trading and decide what order of transactions makes me the most money. You don't necessarily care if someone who's doing a transaction on a DEX get…”
Tomaino: Proof-of-stake will make decentralized organizations more inclusive
“So I think when we see proof of stake, we're going to start to see kind of more inclusive ways to create decentralized organizations that lots of people can participate in.”
Katie Haun notes Ethereum is transitioning to proof-of-stake
“Ethereum is migrating to what's called a proof of stake, so it won't be doing proof of work mining and using all of this energy.”
