Bitcoin Research — Law, Regulation, Markets & Origins (2026)

A research archive on Bitcoin compiled in October 2026: US federal and state law (FinCEN's virtual-currency record from 1999, the 2020 unhosted-wallet rule and its 2026 withdrawal, notes on all 50 states and DC), KYC/AML for buying and selling, banking, exchanges, wallets, payment processors, hacks and their causes, patents, the 2007–2011 origins, and the evidence on who Satoshi Nakamoto is. Every note dates and cites its claims and labels anything unverified, contested or fringe. Government, court and patent records are kept here in full; other sources are cited with a link to the original. Filter by case to pick a topic, such as fincen, states or notes. Download it all as a dataset. Research, not advice. These notes explain what happened and why; they are not recommendations to buy or sell. Statuses of bills and rules are as checked on the date each note gives.
