Research on Monero ring signature-based blockchain privacy and security focuses on leveraging advanced cryptographic techniques to ensure untraceable and unlinkable transactions within the Monero cryptocurrency network. Ring signatures allow a user to sign a transaction on behalf of a group of possible signers, making it computationally infeasible to identify the actual sender while still validating the transaction. This mechanism, combined with stealth addresses and confidential transactions, enhances privacy by hiding both sender and receiver information as well as transaction amounts. Studies analyze the effectiveness of ring signatures in resisting blockchain analysis, preventing double-spending, and maintaining anonymity, while also examining trade-offs in transaction size, computational overhead, and network scalability. Overall, Monero’s ring signature-based approach exemplifies a practical implementation of privacy-preserving blockchain technology that balances security, confidentiality, and performance.
