Resolving the Kardashev's conundrum using a Bitcoin-inspired metric

verified

“In his 1964 paper, "Transmission of Information by Extraterrestrial Civilizations," famed astrophysicist and radio astronomer Nikolai Kardashev addressed the types of transmissions (and at what energies) astronomers should search for in their Search for Extraterrestrial Intelligence (SETI).”

VERIFIED BY REFERENCE

Multiple sources, including the ADS database and Wikipedia, confirm that Nikolai Kardashev published the paper 'Transmission of Information by Extraterrestrial Civilizations' in 1964 regarding SETI.
