At a convention yesterday, Ethereum co-founder and unofficial figurehead Vitalik Buterin argued that Ethereum’s upcoming transition to a proof-of-stake consensus mechanism is a “resolution” to the blockchain’s rampant power consumption that has been incensing critics as of late.
In an interview on the StartmeupHK digital convention hosted from Hong Kong, Buterin mentioned that whereas proof of stake is “nonetheless in its infancy and fewer battle-tested” than Ethereum’s present proof-of-work mannequin, it will probably finally scale back the chain’s power consumption by upwards of 10,000x.
The feedback come amid a interval of rampant criticism of blockchain expertise for its ecological affect — together with from some erstwhile supporters. Tesla founder Elon Musk not too long ago undertook an about-face regarding the automotive firm accepting Bitcoin funds, saying that he couldn’t encourage the usage of fossil fuels through Bitcoin mining. In different threads, he additionally known as for Dogecoin to extend its effectivity throughout a number of key metrics.
Buterin straight responded to those feedback about scalability in a weblog put up on his web site, laying out the issues with making an attempt to scale by merely tweaking the parameters round blocksize.

Earlier within the month, Buterin additionally argued that Bitcoin’s continued use of proof-of-work signifies that the chain, which is at the moment the world’s largest, will finally get “left behind” as customers more and more demand extra energy-efficient and environmentally pleasant choices — a phenomenon he says makes it “potential” that Ethereum finally eclipses Bitcoin and the biggest digital asset.
In the end, Buterin appears to agree with critics concerning the necessity for blockchains to undertake newer, extra environment friendly fashions — particularly because the chain grows in quantity and turns into a broadly relied-upon computational community.
“This factor we’re constructing isn’t only a recreation anymore. It’s a big a part of a brand new period.”
