Yesterday, the on-chain monitoring community erupted in uproar. Someone discovered that an early wallet address attributed to Satoshi Nakamoto suddenly had a transfer record. Since Bitcoin’s birth in 2009, this address had not moved at all; the unusual activity immediately shot it to the top of Twitter’s trending searches.

According to on-chain data, the address first received a test transaction of 0.0001 BTC in the morning, and then, in the afternoon, transferred 1 BTC out to a hot wallet of a major exchange. The whole process looks like someone is testing the wallet’s usability. Roughly 0.999 million BTC still lay in the address, and based on today’s prices, it’s worth close to $80 billion.

However, experts are relatively cautious. An MIT researcher believes this could be nothing more than a security test or some kind of signal, but it’s also possible that the private key was compromised. More worryingly, a professor of cryptography directly warned people not to fall for the “Satoshi revival” scam—anyone demanding that you transfer BTC to unlock an “inheritance” is a scam.

In the community, some people do worry about the risk of large-scale selling, but the Bitcoin development team quickly issued a statement saying that even if the private key really were leaked, it would not affect the security of the Bitcoin protocol itself. In the end, this matter was confirmed to be fabricated news, but it truly served as a reminder to stay alert to on-chain misinformation and phishing attacks.
