The broader cryptocurrency community is divided over whether cleaning up the mining sector is the best path to environmental sustainability. The energy-intensive authentication system that underlies Bitcoin is known as “proof of work”; some in the industry are pushing to build new cryptocurrencies on a different system called “proof of stake,” which uses as little as 0.01 percent of the energy consumed in the mining process.
Mr. Wall said he had no objections to experimentation with an alternative system. Still, he said, he believes in the long-term potential of Bitcoin to transform finance, though he wishes that miners were called something that sounded less extractive, like “validators.”
That’s a battle he’s unlikely to win. But even in the face of backlash, he said, companies will keep mining Bitcoin.
“It’s just going to happen. It’s a reality,” he said. “We need to do it in an environmentally friendly way.”
