SBF continued that the environmental impact of Bitcoin mining, alongside the fact that the coin is “inefficient,” would count against it in the long run.
PoS networks are the future of payments
He added that these networks already have the advantage of lower energy consumption and cheaper costs. So, they could be forced to evolve into the choice network for crypto payment.
In his words,
The Bitcoin network is not a payments network, and it is not a scaling network. Things that you’re doing millions of transactions a second with have to be extremely efficient and lightweight and lower energy cost. Proof of stake networks are.
In his view, Bitcoin’s “speed,” alongside the fact that the blockchain does not host smart contracts, makes it difficult for decentralized applications to be built on top.
SBF believes these shortcomings would allow Bitcoin to “be taken over by other systems that are growing.”
Bitcoin is a store of value
However, SBF didn’t entirely dismiss Bitcoin. He believes the crypto king has a future as “an asset, a commodity and a store of value.”
SBF’s view is not entirely surprising; some crypto community members also think that the flagship digital currency is more of a store of value than a payment option.
The billionaire also rehashed the usual criticism against Bitcoin, saying that the community has to work to avoid
Spending 100 times as much eventually as we are today on energy costs for mining.
Meanwhile, Greenpeace, a non-profit environmental organization, called for a change to the Bitcoin consensus model in a campaign tagged “Change the Code, not the Climate” in March.
However, the Bitcoin community reacted negatively to the campaign, saying that changing the coin’s code would have a ripple effect on the network’s architecture and jeopardize its security.
