Understanding Monero's Privacy Features
Ring Signatures
What They Are: Ring Signatures are a cryptographic technique used in Monero to provide anonymity for the sender of a transaction. By signing a transaction with a group of potential signers, Ring Signatures obscure the identity of the actual sender.
How They Work: When you send Monero, your transaction is signed with your private key. However, it is combined with several other public keys from the blockchain, creating a 'ring' of possible signers. To an observer, it appears that any one of these members could have signed the transaction. This method makes it nearly impossible to trace the origin of the transaction.
Stealth Addresses
What They Are: Stealth Addresses are designed to protect the privacy of the recipient of a transaction. Instead of using a single public address, Monero generates a unique, one-time address for each transaction.
How They Work: When someone sends Monero to you, they don’t use your regular address. Instead, they use a one-time stealth address derived from your public address. This unique address is used only for that specific transaction, and only you can recognize it as belonging to you. This prevents anyone from linking the transaction to your public address by looking at the blockchain.
RingCT (Ring Confidential Transactions)
What It Is: RingCT, or Ring Confidential Transactions, is an enhancement of Ring Signatures that adds confidentiality to the transaction amounts. It ensures that the value of the transaction remains hidden while still allowing verification of its validity.
How It Works: RingCT combines Ring Signatures with Confidential Transactions. It uses cryptographic proofs to confirm that the total amount of inputs equals the total amount of outputs without revealing the actual amounts. This feature ensures that transaction amounts are concealed from public view, adding another layer of privacy.
