TL;DR: China’s historic cryptocurrency activity, including periods where miners controlled as much as 65% of global hashrate, is now being reassessed as the government tightens controls and advances the digital yuan, according to Chainalysis. The governance lesson is that state policy can rapidly reconfigure transaction, custody, and monitoring assumptions across digital asset ecosystems.
NHIMG editorial — based on content published by Chainalysis: Analyzing China’s Historic Cryptocurrency Activity Amidst Government Crackdowns
By the numbers:
- Miners from China have historically been dominant, at times controlling as much as 65% of global hashrate.
Questions worth separating out
Q: How should organisations assess risk when digital currency ecosystems shift toward state control?
A: They should separate market volatility, custody exposure, and regulatory change into different risk categories.
Q: Why does mining concentration matter in a blockchain network?
A: Mining concentration matters because it can create operational dependence on a small number of participants even when the network is technically distributed.
Q: What do security and compliance teams get wrong about decentralised systems?
A: They often assume decentralisation removes governance dependencies.
Practitioner guidance
- Separate protocol risk from policy risk Track network-level resilience, custody exposure, and regulatory change as distinct risk categories rather than treating them as one crypto issue.
- Review custody controls around approval authority Identify who can initiate, approve, and revoke transfers across wallets and exchange accounts, then test whether those controls are documented and monitored.
- Use on-chain evidence in governance reviews Bring transaction history, concentration trends, and ecosystem migration data into periodic risk reviews so decisions are based on observed behaviour rather than assumptions about decentralisation.
What's in the full report
Chainalysis' full report covers the operational detail this post intentionally leaves for the source:
- Historical blockchain analysis of China’s mining activity and transaction volume, including the evidence base behind the 65% hashrate figure.
- The report’s discussion of both legal and illicit transaction patterns, which is useful for teams comparing policy risk to enforcement risk.
- Expert interview context on the motivations behind the crackdown and what they may mean for future digital currency governance.
- A closer look at the digital yuan project, including the possible goals and ecosystem effects that are only summarised here.

State-led digital currency is a governance model change, not just a payments update. The report shows how the move toward the digital yuan sits alongside pressure on traditional cryptocurrencies, which means control is shifting from distributed network participants toward policy-defined issuance and oversight. For security and identity teams, that matters because trust boundaries are being redrawn around who can participate, observe, and transact. Practitioners should treat digital currency programmes as governance architecture, not only as financial technology.
A question worth separating out:
Q: How can teams monitor digital asset activity without overrelying on narrative analysis?
A: Use transaction data, concentration trends, and policy developments together. On-chain evidence shows how the ecosystem is actually behaving, while open source research and interviews explain why. That combination produces a more defensible view of risk than headlines or ideology alone.
