In an era when memories can be traded, the young computer genius Shi Sui witnessed the privacy chaos of black market memory trading and determined to create a "memory blockchain" to protect the soul. He met the idealistic ethicist Gu Weiche and jointly founded the "Heartmark Chain" - a memory trading platform that uses zero-knowledge proofs to automatically blur faces and differential privacy algorithms to transform pain into abstract codes. Faced with the monopoly ambitions of the giants, Shi Su used technology as a spear and Gu Weiche used ideas as a shield to unite various figures to launch a "memory rights" movement. From code debates in campus cafes to legislative battles in the parliament building, they built a privacy wall for everyone's "heart traces" in the flood of data. Finally, the "Memory Data Sovereignty Act" illuminated reality and painted an urban picture of technology protecting human nature.
