Lisbon Bitcoin Maximalists are back on Saturday, October 31st to celebrate Bitcoin White Paper Day and, of course, Halloween..
Eighteen years ago today, a nine-page PDF landed on a cryptography mailing list and everyone with a plausible excuse has been denying they wrote it ever since.
Bitcoin is officially a legal adult. Old enough to vote, sign contracts, and open a bank account, which is funny, because it has spent its entire life making the last one optional.
It’s also Halloween, which this year needs no extra effort: Coldcard’s RNG in August, Ledger’s complimentary spy chip in October. The scariest costume at this meetup is a hardware wallet bought from a reseller.
So this time we’re doing lunch. Come celebrate, argue, and raise a glass to a document that has aged better than most of its critics.
Food and drinks available to order — it’s a birthday, eat something. Costumes optional. Read the whitepaper beforehand: it’s nine pages, you’ve spent longer on worse Twitter threads.
Discover Nina – Brunch & Speciality Coffee, the brunch café hosting us in Parque das Nações, Lisbon; near the Myriad by SANA hotel and Vasco da Gama Tower.
