Nic Carter and Hasu Begin Bitcoin Unforgeable Costliness Research
Bitcoin researchers Nic Carter and Hasu begin publishing research on Bitcoin's unforgeable costliness, analyzing how proof-of-work creates digital scarcity.
On April 6, 2018, Bitcoin researchers Nic Carter and pseudonymous analyst Hasu began collaborating on research examining Bitcoin's 'unforgeable costliness'—the idea that Bitcoin's value derived from the verifiable computational work and energy expenditure required to produce it. Their research would become influential in articulating why proof-of-work mining wasn't wasteful but rather the mechanism creating Bitcoin's fundamental properties of scarcity and security.
The concept of unforgeable costliness, originally articulated by cryptographer Nick Szabo, held that valuable money required costly production that couldn't be easily faked or counterfeited. Historically, precious metals like gold served this function: gold's rarity and the difficulty of mining it created natural scarcity.
Carter and Hasu argued that Bitcoin achieved digital unforgeable costliness through proof-of-work: the computational difficulty and energy expenditure required to mine new Bitcoin and secure the network created verifiable costliness that couldn't be forged or faked. This property made Bitcoin fundamentally different from traditional digital goods that could be costlessly copied.
The research addressed growing criticism of Bitcoin mining's energy consumption by reframing it not as waste but as the necessary cost of creating digital scarcity and security. Just as gold mining consumed resources to provide sound money, Bitcoin mining consumed electricity to provide digital sound money. The Carter-Hasu research examined various aspects of Bitcoin's costliness including mining economics, difficulty adjustment mechanisms, the relationship between hash rate and security, and how Bitcoin's proof-of-work compared to alternative consensus mechanisms.
For Bitcoin's intellectual foundations, the unforgeable costliness research provided rigorous articulation of why Bitcoin's design choices—particularly proof-of-work mining—were essential to its value proposition rather than arbitrary or improvable technical decisions.The research influenced how many Bitcoin advocates explained and defended Bitcoin's energy usage, shifting the conversation from apologizing for energy consumption to explaining why it was feature rather than bug.
