1. What Is a Private Transaction
A private transaction is a blockchain transaction whose contents — sender, recipient, amount, or calldata — are hidden from public view until revealed or never revealed, using encryption, ZK-proofs, or private mempools.
2. How It Works
Privacy can be achieved at several layers: private mempools (hiding from MEV bots before inclusion), encrypted mempools (e.g., Shutter), confidential transactions (hiding amounts via Pedersen commitments), and ZK rollups (validity proofs that hide state). Fully private chains (Monero, Zcash) hide balances and flows by default.
3. Why It Matters
Privacy protects users from front-running, surveillance, and financial profiling — and is a legal requirement for some businesses. The tension between privacy and regulation (AML, sanctions) defines the debate. Private transactions are essential infrastructure for institutional adoption and personal financial freedom.
4. Key Facts
- ZK proofs verify correctness without revealing data
- Monero (RingCT) and Zcash (zk-SNARKs) are privacy chains
- Private mempools (Flashbots) protect against MEV, not privacy
- Regulated entities need privacy with selective disclosure
