Abstract
With the popularity of Blockchain comes grave security-related concerns. Achieving privacy and traceability simultaneously remains an open question. Efforts have been made to address the issues, while they may subject to specific scenarios. The present disclosure proposes a method, a system, and a device for maintaining privacy and traceability of a Blockchain-based system. The method includes: registering in a Blockchain-based system; transmitting a message from a transmitter T to a receiver R via an anonymous network, after a registration request of the transmitter T has been approved and storing message transmission data generated during a message transmission process in a Blockchain; and performing an identity disclosure by using the message transmission data when the message is detected to be false. The anonymous network may transmit the message by onion routing. The solution proposed by the present disclosure can achieve traceability and privacy for a Blockchain-based system simultaneously.
