In November, at the North American Blockchain Summit in Fort Worth, Mr. Porter interviewed Senator Ron Wyden, Democrat of Oregon, about the benefits of blockchain technologies.
Mr. Wyden spoke of the promise of a “digital dollar” and putting medical records on a blockchain, a digital ledger that records cryptocurrency transfers. But later, in an interview with The Times, Mr. Wyden said he opposed the state bills pushed by the Satoshi Fund, including the one in Arkansas, and the energy-intensive process required for Bitcoin mining.
“It’s pretty clear that I’m not a big supporter,” he said. “Quite the opposite.”
In Greenbrier, as the lawsuit wears on, Ms. Anderson said she and her neighbors have struggled to pay their lawyer. A fund-raiser in October brought the community together, but the proceeds barely put a dent in their debt. Still, she says, as long as they can afford it, they will fight the mine.
“I don’t want to be run out of my home,” she said.
