# Privacy Features BlackCoal implements several privacy features to protect users' identities and transaction details: #### 1. Confidential Transactions All BlackCoal transactions are confidential, concealing the transaction amount. This ensures that the blockchain does not expose sensitive financial information. #### 2. Ring Signatures Ring signatures are used to mix the sender's transaction with others, making it impossible to determine the true source of a transaction. #### 3. Stealth Addresses Stealth addresses are generated for each transaction, ensuring that the recipient's identity remains hidden on the blockchain. #### 4. Zero-Knowledge Proofs Zero-knowledge proofs (zk-SNARKs) are used to validate transactions without revealing transaction details, further enhancing privacy. #### 5. Coin Mixing BlackCoal employs coin mixing techniques to obfuscate transaction histories, making it challenging to trace the origin of funds. --- # Agent Instructions This documentation is published with GitBook.
