On January 19, 2018, Laszlo Hanyecz — famous for spending 10,000 BTC on two pizzas in 2010 — completed the first documented Lightning Network purchase on Bitcoin mainnet. He bought a YubiKey router for 0.00649 BTC via a Lightning payment routed through ACINQ's mainnet node. The payment settled in block 498,222, proving that SegWit's malleability fix had unlocked real off-chain payments.
