the claim

Bitcoin uses a proof-of-stake consensus mechanism.

the verdict
REFUTED
the evidence says no
Recorded sources
0 sources for · 4 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Bitcoin uses a proof-of-stake consensus mechanism?

No. Multiple peer-reviewed sources state that Bitcoin uses the proof-of-work consensus mechanism, not proof-of-stake; one notes Ethereum moved from PoW to PoS while Bitcoin did not.
