A recent peer-review white paper finds that Bitcoin’s blockchain uses almost half the annual energy of previous estimates.
-
The Valuechain publication also shows that Bitcoin is 56 times more energy efficient than the current banking system.
Peer reviewed rapport her:
Key takeaways:
We demonstrate that Bitcoin consumes at least 28 times less energy and can run today with 60 times less energy than the classical system. At a single transaction level and with total volumes accounted for, Bitcoin produces equivalent energy efficiency rates or better. When Bitcoin Lightning is compared to Instant Payment scheme, Bitcoin gains exponentially in scalability and efficiency, proving to be millions of times more energy efficient per transaction than Instant Payments.
