In brief:
- Evidence found in Bitcoin's early code suggests that Satoshi Nakamoto used a Russian proxy sever.
- The proxy also leads to a Russian user named Sergey and his various hotel reviews.
- Not everyone is convinced that the findings provide evidence of a proxy.
Few details are known about the private creator of Bitcoin, and new evidence might reveal why. Analysis of early Bitcoin code hints that Satoshi Nakamoto may have relied on a Russian proxy server to mask his location.

According to a report from Cointelegraph, a section in Bitcoin's early code exhibits signs of obfuscation via the possible use of a cipher.

What if Satoshi Nakamoto suddenly returned?
His return is imperceptible, at first a faint rumour in some dark reach of the web. A lone cybersecurity researcher uncovers curious activity on a long-dormant Bitcoin wallet, unused since 2011. It appears a single “satoshi”—worth 1/millionth of a bitcoin, the smallest possible unit—has been transferred from one of the digital wallets believed to have been owned by Satoshi Nakamoto, Bitcoin’s presumed dead inventor. The researcher tweets about it. Soon the gossip grows in frequency, screaming...
The apparent cipher appears within a file dubbed "Bitcoin v0.1.0 irc.cppm.” The latter part refers to Bitcoin's Internet Relay Chat channels. The code apparently links to a proxy IP address associated with the now-defunct Russian Internet service provider Anders Telecom. Much like a VPN, a proxy hides the physical location of an IP address.
The inclination is that Nakamoto may have used a Russian Proxy server to avoid detection. Tracing the IP address apparently pulls up a user named "Sergey," employing the same proxy as Satoshi. Per the report, Sergey posted reviews of hotels in Vietnam in December 2008 and January 2009.
Satoshi, where art thou?
Not everyone is convinced that the findings actually mean anything.
"The whole story reminds me a little 'you can make statistics say anything you want.' For me it's a simple reminder about the expected format of some variable in order to know how to process it later and take it at random," CTO of GEODB Javier Estrella told Cointelegraph.

$500,000 Bitcoin stash from Satoshi era just moved
A long term Bitcoin hodler—or someone who just found an old wallet—has moved a large amount of Bitcoin, mined during the network's earliest days. Today, 50 Bitcoin, worth $500,000 today, was moved, and split up into two addresses in one transaction. As pointed out by Coindesk reporter Zack Voell, the coin was mined in block 3,654—and hadn't moved since then. It's not every day you see coins from the 3000s block heights moving around. https://t.co/ozHpq4m1Up pic.twitter.com/jkRhf7Kcme — Zack Voe...
Still, the conversations between Satoshi and early members of the Bitcoin community seem to indicate that IRC was used in conjunction with identity obfuscation.
As for why Satoshi would use a Russian proxy, in particular, it may have something to do with Russia's disconnect from western intelligence agencies. Either that or Satoshi was a Russian named Sergey. Now that would be a twist.
