在Steam等主流平台,“买游戏”只是获得一份可随时撤销的有限授权,游戏程序、存档、道具等所有数据均不属于你;中国《民法典》第127条虽承认虚拟财产应受保护,但未明确归属,司法实践中法院多判运营商拥有数据所有权,用户仅有使用权。今天游戏里的"资产"只是一种债权——一份你对运营商持有、可被随时撤销的许可。而这项技术把它变成物权:一种存在于"物"本身之中、可对任何人主张、不依赖任何人服务器的权利。《民法典》说虚拟财产"应受保护",却没能说清"如何"保护——因为过去没办法让"占有"独立于运营商而存在。私钥,加上一个永久的链上账本,正是这个"如何"。它不必等法院来裁定归属,而是让所有权成为一个数学事实。"应受保护"于是变成"由结构本身来保护"。即便运营商关停,资产也不会随之消失——因为它从来不在他们的服务器上,而是在你的私钥之下。On mainstream platforms such as Steam, purchasing games only grants a revocable limited license, and you do not own any data including game programs, save files and in-game items. Although Article 127 of China's Civil Code acknowledges that virtual property deserves legal protection, it fails to clarify ownership. In judicial practice, courts mostly rule that operators hold ownership of such data while users merely enjoy the right of use. Current in-game "assets" are essentially creditor's rights, namely revocable permissions held by users against operators. However, this technology converts them into property rights: rights inherent to the asset itself, enforceable against any party, and independent of third-party servers. The Civil Code stipulates virtual property "shall be protected" yet fails to specify how protection is realized, since previously possession could not exist separately from platform operators. Private keys paired with permanent on-chain ledgers provide the solution to this "how". Ownership becomes a mathematical certainty rather than requiring judicial confirmation. Protection by legal provision thus evolves into inherent structural protection. Even if an operator shuts down its service, assets remain intact, for they are never stored on the operator’s servers but secured under your private key.
