Bitcoin did not emerge from an intellectual vacuum.
Why it matters
His record connects cypherpunk ideas to working systems without pretending that one precursor was already Bitcoin.
The build
RPOW made proof-of-work tokens reusable through trusted hardware. It addressed a different trust model, but demonstrated that computational work could become a transferable digital object.
What he saw
Finney treated Bitcoin as an experiment worth running, not a finished certainty. His technical participation helped move the idea from a paper into observable network behavior.
Right, disputed, evolved
Proof of work became central to Bitcoin, while RPOW's trusted-hardware dependency did not. Later networks pursued other consensus models, leaving the security and energy debate open.
