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 might probably ultimately reduce the chain’s energy consumption by upwards of 10,000x.


The feedback come amid a interval of rampant criticism of blockchain know-how for its ecological affect — together with from some erstwhile supporters. Tesla founder Elon Musk not too long ago undertook an about-face in regards to the car company accepting Bitcoin funds, saying that he couldn’t encourage using fossil fuels by way of Bitcoin mining. In different threads, he additionally referred to as for Dogecoin to extend its effectivity throughout a number of key metrics.

Buterin instantly responded to those feedback about scalability in a weblog post on his web site, laying out the issues with attempting to scale by merely tweaking the parameters around blocksize.

Earlier within the month, Buterin additionally argued that Bitcoin’s continued use of proof-of-work implies that the chain, which is at present the world’s largest, will finally get “left behind” as customers increasingly demand more energy-efficient and environmentally friendly options — a phenomenon he says makes it “doable” that Ethereum finally eclipses Bitcoin and the most important digital asset. 

Finally, 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 sport anymore. It’s a big a part of a brand new period.”
