Regulation and Society

Blockchain protocols cross legal, institutional, and social systems. A private key can control an asset while a custodian's records determine a legal claim. A public ledger can permit pseudonymous use while exchanges collect identity documents. A censorship-resistant settlement layer can still be reached through regulated banks, hosted interfaces, stablecoin issuers, and internet providers.

This section separates technical capability from legal obligation and political judgment. Regulatory descriptions are current through 24 September 2026 and name their jurisdiction. They are educational summaries, not legal, tax, or compliance advice.

Reading regulatory claims

FATF recommendations are international standards implemented through national law; they are not self-executing global statutes. European Union regulations apply within their stated scope. Brazil's framework assigns defined responsibilities to the Banco Central do Brasil while preserving responsibilities of bodies such as the CVM and Receita Federal. A protocol may be global while service providers remain subject to the law of their place of establishment, customers, and activity.
