CBDCs vs. Bitcoin: Why Central Banks Are Building the Opposition

Central Bank Digital Currencies represent governments’ attempt to create a “controlled” alternative to Bitcoin. Understanding what CBDCs are, how they work, and why Bitcoin poses an existential threat to their design is essential for understanding the future of money.

What Is a CBDC?

A CBDC is a digital currency issued by a central bank — essentially a government-issued cryptocurrency without the decentralization. TheBank of England describes it as “a digital form of central bank money that households and businesses could use to make payments.”

Unlike Bitcoin:

• The central bank controls the supply
• The government can restrict transactions
• Accounts can be frozen
• Transaction data is visible to authorities
• No self-custody — the government holds your CBDC

CBDCs exist on a spectrum of control:

Account-based CBDCs: The government holds your account directly. Every transaction is visible. Spending limits, geographic restrictions, and transaction blocking are technically possible.|N
