Laszlo Hanyecz is a specific People coordinate in the Bitcoin knowledge graph. In practical terms, it identifies the subject described here: Early miner and developer who made the 10,000 BTC pizza purchase, a landmark demonstration of Bitcoin acquiring a market exchange value. This definition is narrower than promotional usage and should be read together with the implementation, date and evidence attached to the entry.
Early miner and developer who made the 10,000 BTC pizza purchase, a landmark demonstration of Bitcoin acquiring a market exchange value. The linked coordinates show the person's projects, ideas, disputes and historical effects.
Primary or authoritative records make these details checkable: Laszlo Hanyecz contributed early Bitcoin code and in May 2010 offered 10,000 BTC for two pizzas in a public forum thread, creating a documented example of exchanging bitcoin for delivered goods. They should be verified before using the coordinate in analysis.
The practical limit is: the later fiat value of the coins is hindsight, not the contemporaneous price or proof of a bad decision; the event should not be described as the first possible transfer, purchase or merchant acceptance without qualification. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
For the clearest picture, read this entry together with Bitcoin Pizza Day, Mining, Medium of exchange, Price discovery, Merchant adoption, Satoshi Nakamoto. The reverse links also lead from Bitcoin Pizza Day.
