The "Memory Merchant" Li Mo of 2063 is not reselling fragments of history—he's trading in the future.

His business is quite unique. With the rise of decentralized storage systems like Walrus, data itself has gained unprecedented value. No longer controlled by internet platforms, but instead governed by creators through smart contracts that precisely set the rules.

Take three items from his shop as examples.

A blue cube contains "2025 World Cup Final, recorded in full immersive 360°." Watching it for free is no problem, but the rules are hardcoded on the chain—each playback automatically allocates 0.001% of the revenue to the players' welfare fund for that year. No one can modify or bypass it. This is called "moral data."

The golden one is a private collection called "Echoes of the Abyss" by AI artist "Stardust." Buyers have exclusive display rights for 100 years. Sounds good, but the key is—after 100 years, the content automatically enters the public domain. Don't get too excited yet; every secondary creation derived from it will have 5% of its revenue flow into Stardust's descendants' wallets. The rules layer upon layer, addressing intergenerational rights.

The most fascinating is the gray cube. At first glance, it looks unremarkable, but it is a pregnancy diary from 2028. The mother began recording after being diagnosed with a rare genetic disease in her child—this life record is permanently sealed on the chain, with ownership, access rights, and derivative rights all managed by a smart contract.

This is the true change brought by the Walrus era: not the technology itself, but that data finally has its own "destiny." In the past internet, data was a resource; now in the on-chain world, data is the subject.
