Blockstream CEO Adam Back said that Castle Island Ventures founding partner Nic Carter is “not helping” the ongoing quantum-Bitcoin narrative for Bitcoiners.
Blockstream CEO Adam Back has criticized Castle Island Ventures founding partner Nic Carter for amplifying concerns about quantum computing threats to Bitcoin.
“You make uninformed noise and try to move the market or something. You’re not helping,” Back said in an X post on Friday, after Carter explained in an X post why Castle Island Ventures invested in Project Eleven, a startup focused on protecting Bitcoin and other crypto assets from the threat of quantum computing.
Back said the Bitcoin community is not in denial about the need to research and develop protections against potential quantum computing threats, but is instead doing that work “quietly.” However, Carter refuted Back’s comment, arguing that many Bitcoin developers are still in “total denial” about the risk of quantum computing to Bitcoin.
