A viral social media meme on X (formerly Twitter) in 2025 suggests that a mere 24-word phrase could unlock Satoshi Nakamoto’s estimated 1.1 million Bitcoin, worth roughly $111 billion at Bitcoin’s price of $101,702 on November 12, 2025. However, this claim has been thoroughly debunked by experts, including Alex Thorn, lead researcher at Galaxy Digital, and Sani, founder of timechainindex.com.
Timeline Mismatch: BIP39 Came After Satoshi
Alex Thorn explained on X: “Fake news, dumb slop. Satoshi’s coins are spread across many pay-to-public-key (P2PK) addresses — i.e., many public-private key pairs, not one. But even worse: hierarchical deterministic (HD) wallets (BIP-32) and mnemonic seed phrases (BIP-39) weren’t invented until 2012/2013.” Sani added that to unlock 1,123,540 BTC, one would need 22,471 private keys, calling any attempt to crack even a single key “futile.”
BIP39 was proposed on September 10, 2013, standardizing 12- or 24-word seed phrases for wallet recovery. By contrast, Satoshi Nakamoto mined the first Bitcoin blocks beginning in January 2009 and last communicated publicly on December 12, 2010, when he posted about addressing denial-of-service vulnerabilities. He vanished years before BIP39 existed.
Early Bitcoin Used Raw Private Keys
Early Bitcoin software, which Satoshi used, generated raw 256-bit private keys represented in hexadecimal, stored directly in wallet files. These keys cannot be derived from any modern seed phrase. Blockchain explorers such as Arkham Intelligence, Blockchair, and mempool.space confirm that Satoshi’s addresses — identified via Patoshi block patterns — have never transacted since 2010, providing clear on-chain evidence that no mnemonic-based attack has ever succeeded.
The Mathematical Impossibility of Brute-Forcing 256-bit Keys
Even if someone attempted to brute-force a single 256-bit private key, the number of possible combinations is 2^256, approximately 1.1579 × 10^77. That number is comparable to the estimated 10^78 to 10^82 atoms in the observable universe. Current global computing power, running at around 10^21 operations per second, would require an average of 1.8 × 10^48 years to crack a single key — a duration vastly exceeding the universe’s 13.8 billion-year age.
Education Gaps and Social Media Engagement
The viral misinformation highlights broader gaps in cryptocurrency education. The misleading post received over 1,200 likes on X, while Thorn’s corrective reply got only 389 likes, and Sani’s about 77. As Bitcoin’s security relies on cryptographic principles established in 2009, the persistent myth serves as a reminder of the need for accurate information about blockchain fundamentals.
FAQ
- When was BIP39 introduced? September 10, 2013, standardizing mnemonic seed phrases.
- What type of keys did Satoshi Nakamoto use? Raw 256-bit private keys generated by early Bitcoin software, not BIP39 seed phrases.
- How long would it take to brute-force a 256-bit key with current computing power? Approximately 1.8 × 10^48 years on average.
- Has Satoshi’s wallet shown any activity in 2025? No. All known addresses remain dormant since 2010.
