Produced by running the paid packet-validation path on a public packet of widely repeated claims about Bitcoin's origins. This is the exact output format a $0.25 packet returns: per-claim verdict, primary-source figure, receipt. Packet submitted as received; verdicts checked 2026-10-18.
| # | Claim as submitted | Verdict | Primary-source figure / receipt |
|---|---|---|---|
| 1 | "Bitcoin was created in 2007." | CORRECTED | The whitepaper "Bitcoin: A Peer-to-Peer Electronic Cash System" is dated 31 Oct 2008 (bitcoin.org/bitcoin.pdf). The genesis block was mined 3 Jan 2009. No 2007 artifact exists in the primary record. |
| 2 | "Bitcoin's supply is capped at 21 million." | VERIFIED | The reference implementation's consensus rules halve the block subsidy every 210,000 blocks from 50 BTC, converging on 21,000,000 BTC (Bitcoin Core source, validation.cpp / amount.h MAX_MONEY = 21,000,000 * COIN). |
| 3 | "The genesis block contains a newspaper headline about bank bailouts." | VERIFIED | Genesis block coinbase text (block 0, blockstream.info/block/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f): "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks." |
| 4 | "Satoshi Nakamoto is a Japanese man born in 1975." | UNVERIFIED | The only source is a self-reported P2P Foundation profile (birth date 5 Apr 1975). No primary document establishes the identity, nationality, or birth date of the author(s). A self-report is not a primary source for identity. |
| 5 | "The first Bitcoin transaction sent 10 BTC from Satoshi to Hal Finney." | VERIFIED | Block 170, transaction f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16: 10.00000000 BTC, Satoshi to Hal Finney, 12 Jan 2009 (blockstream.info). |
| 6 | "Bitcoin has never been hacked." | CORRECTED | Too broad as stated. The protocol had a critical value-overflow incident on 15 Aug 2010 (block 74638 created ~184 billion BTC; the chain was forked to remove it — Bitcoin CVE-2010-5139). Exchanges and wallets have also been compromised, which is a different claim from the protocol's. As written: corrected. |
