Bitcoin Privacy

Privacy concepts for Bitcoin users, including address reuse, transaction history, UTXOs, and metadata exposure.

What is Bitcoin Privacy?

Bitcoin transactions are permanently public. Addresses are pseudonymous by default, but chain analysis firms trace fund flows through transaction patterns and address reuse.

What is CoinJoin?

CoinJoin combines multiple Bitcoin inputs into a single transaction with equal-value outputs, breaking the deterministic link between input and output on-chain.

What is PayJoin?

PayJoin is a two-party Bitcoin transaction where both sender and receiver contribute inputs, defeating chain analysis change-detection heuristics without a coordinator.

Running a Bitcoin Node

Running a full Bitcoin node means verifying every transaction and block yourself, without relying on a third-party server that can observe your activity.

Using Tor with Bitcoin

Tor routes Bitcoin network traffic through relays to hide your IP address from peers, analytics firms, and network observers.
