Climate Campaign Pushes Bitcoin Network To Drop Energy-Hungry Code

Greenpeace and other environmental groups launched a new campaign today to push the Bitcoin network to slash its growing greenhouse gas emissions. The Verge reports: The goal of the campaign, dubbed "Change the code, not the climate," is to switch up the energy-hungry process of verifying transactions and mining new Bitcoins. [...] In order to validate transactions, Bitcoin miners rely on specialized hardware to solve complex puzzles. Their computers gobble up a lot of energy in the process, and the miners get new tokens in return. It's a process called "proof of work," in which the energy used is sort of the price paid to verify transactions. The process is deliberately energy-intensive as a safety measure. The baked-in inefficiency is meant to discourage bad actors from manipulating the data because it would cost a lot of energy to do so. The new campaign aims to move Bitcoin away from that energy-hungry proof of work process. The most popular alternative is called proof of stake. Cryptocurrencies that use proof of stake use vastly less energy because there are no puzzles to solve. Instead of essentially paying with electricity to participate in the process, you have to offer up some of your own tokens. This is supposed to prove that you have a "stake" in keeping the ledger accurate. If you mess anything up, you lose tokens as a penalty. While proof of stake might make solve a lot of Bitcoin's pollution problems, experts have been skeptical that miners would be willing to make the change. Miners invest a lot in their hardware and would be hard-pressed to abandon it. And some fans of proof of work maintain that it's the most secure way to maintain the ledger. "We know Bitcoin stakeholders are incentivized not to change," the campaign acknowledges on its website. "Changing Bitcoin would render a whole lot of expensive infrastructure worthless, meaning Bitcoin stakeholders will need to walk away from sunk costs -- or find other creative solutions." As the Guardian notes, the campaign is launching a huge digital advertising push via the Wall Street Journal, New York Times, Marketwatch, Politico, Facebook and others. "Organizers are also taking legal action against proposed mining sites and using their large memberships to push bitcoin's biggest investors and influencers to call for a code change." Additionally, the campaign is urging people to tweet at cryptocurrency influencers to support the campaign.
