The campaign aims to change bitcoin’s proof-of-work (PoW) consensus algorithm, which requires vast amounts of energy. Larsen is putting $5 million into the ad campaign, which is dubbed “Change the Code, Not the Climate” and set to roll out over the next month, according to Bloomberg. The campaign will run ads in leading publications such as the New York Times, Politico and The Wall Street Journal, and some of the ads will take aim at bitcoin’s most famous supporters including Tesla (TSLA) CEO Elon Musk, Block (SQ) CEO Jack Dorsey and Fidelity CEO Abby Johnson, according to the Journal.
