Mysterious On-Chain Bitcoin Puzzle Claims Private Key Derived From Genesis Block

A mysterious Bitcoin puzzle was lodged on-chain this week — and it claims the private key was generated from data in Satoshi Nakamoto’s Genesis Block. What happened - On Aug. 22 at ~19:45 UTC, Foundry USA mined block 963,629. Galaxy Research flagged a transaction in that block on Aug. 23 that contains a 255‑byte human‑readable message placed in an OP_RETURN output. - The on‑chain text states the author “created a Bitcoin puzzle using information contained in the Genesis Block created by Satoshi to generate the wallet,” and adds that the wallet’s entropy is “extremely low” and that no private backup was needed because “everything I needed was already in the Genesis Block.” - The transaction was 500 bytes total, paid 250 satoshis in miner fees (≈0.60 sat/vB). Galaxy Research described the 255‑byte payload as an “oversized OP_RETURN” because it’s unusually large compared with typical data outputs. What this actually proves (and what it doesn’t) - Embedding the message on-chain proves the text existed by that time, but it does not prove the author’s identity, the derivation formula, or that anyone has solved the puzzle. - As of publication there was no verified evidence anyone had derived the purported private key or moved any reward. The only way to verify a solution would be an outgoing transaction signed by the puzzle wallet’s private key or a similarly cryptographic proof. Why the Genesis Block matters here - Bitcoin’s Genesis Block (block 0), mined by Satoshi on Jan. 3, 2009, contains publicly known values that could be used as inputs to a key‑generation scheme: the block hash (000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f), timestamp, nonce, Merkle root, a public key, and the embedded newspaper headline: “The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.” - Blockstream’s reference lists the Genesis Block timestamp as 1231006505 and nonce as 2083236893. Because these values are public, anyone can recreate them — but they still need to know precisely which values were used and how they were transformed to reproduce the author’s claimed wallet. Security reminder - Entropy is the randomness underlying private‑key generation. Secure wallets use large, unpredictable entropy. If a private key is derived from known public data (or from a low‑entropy process), an attacker who figures out the generation method can reproduce the key and steal funds. - The Genesis Block’s original 50 BTC subsidy is not relevant here: those coins are unspendable due to how the original implementation handled the coinbase. Bottom line This is a newly published on‑chain Bitcoin puzzle built around public Genesis Block data. It’s intriguing, but unproven. The crypto community will be watching for a signed spend or other cryptographic proof that someone derived the private key — until then, it’s a provable message on the blockchain, not a revealed secret from Satoshi.
