Coinkite's CTO is accused of having ignored RNG code warnings a year in advance, involving over 1800 BTC stolen
Bitcoin News posted on the X platform that new evidence shows the anonymous switck account that wrote the LibNgU code may actually be Peter Gray, co-founder and CTO of Coinkite, as the code is at the core of the COLDCARD entropy failure incident.Researchers claim that Gray's GPG key signed dozens of switck submissions, and other identifiers seem to link the two identities. Bitcoin developer James O'Beirne stated that he warned Coinkite in May 2025 that the RNG implementation of LibNgU looked suspicious and suggested removing it, but he said the response was that any issues should have already been discovered. Screenshots also show that as early as April 2021, users had already questioned the rewrite of LibNgU.If these findings are accurate, it means that the engineer who introduced the code was later associated with the theft of over 1,800 BTC and had received direct warnings about the RNG implementation more than a year before the vulnerability was publicly disclosed.
