China's Supreme People's Court rules that blockchains can be legally used to authenticate digital evidence in legal disputes
Context & Ripple Effects
In 2018, China's Supreme People's Court ruled that blockchains can legally authenticate digital evidence in disputes — an early judicial endorsement of tamper-evident record-keeping that preceded the state's broader blockchain buildout across manufacturing, taxation, and law enforcement. The ruling sits inside a deliberate split in Chinese policy: the ledger technology is legitimized while the token layer is not, a line later drawn sharply when the Supreme Court classified crypto transactions as illegal fundraising.
First-order effects
- Litigants and platforms can now submit blockchain-stored records — timestamps, hashes, transaction logs — as admissible evidence in Chinese legal disputes, giving courts a verifiable alternative to contested screenshots and server logs.
Second-order effects
- Blockchain vendors and government IT integrators gain a courtroom-grade use case to sell into, reinforcing the same state-led deployment track the later 15-city pilot formalized.
Third-order effects
- The ruling institutionalizes China's 'blockchain without crypto' model: distributed ledgers adopted as judicial and administrative infrastructure while the asset layer remains criminalized — a template other jurisdictions weighing evidence-law reform can copy selectively.
The trend: China is absorbing blockchain into state infrastructure — courts first, then city-scale pilots — while steadily tightening the ban on the cryptocurrency layer the technology was built to carry.
