China's 2017 notice banned token sales, not the code

Inherited archive entry · retained from the earlier edition. Its factual, legal and policy claims have not all been reverified for 19 September 2026. Research scope.

Seven agencies, one notice, immediate effect

On 4 September 2017, the People's Bank of China and six other agencies, the Cyberspace Administration, the Ministry of Industry and Information Technology, the State Administration for Industry and Commerce, and the banking, securities and insurance regulators, jointly issued a notice on the risks of token financing. The notice characterises token offerings as a form of unauthorised public fundraising, stating that such activity involves suspected illegal token sales and unlicensed securities issuance. It ordered that all token financing activities cease immediately, that organisers of completed offerings arrange refunds to protect investors, and that financial institutions and payment processors stop offering accounts, trading or settlement services connected to tokens.

A ban on people and institutions, not on code

The notice also barred trading platforms from converting between fiat currency and virtual currency or providing pricing and information services for tokens, and it called for telecommunications authorities to pursue closing non-compliant platforms' websites and applications. Every one of these instructions targets a jurisdiction's institutions, exchanges, banks, payment processors, registered platforms, rather than the underlying software. A token built to the ERC-20 interface continues running on Ethereum regardless of what a national regulator orders, because its transfer and approval functions execute on validating nodes distributed across many jurisdictions, none of which this notice reaches directly.

Where a permissionless network and a jurisdictional order actually meet

The order's force falls on the on-ramps and off-ramps: the exchanges and payment rails that convert a token into currency a resident can spend, and the institutions that would otherwise service token issuers. That is a real constraint. A resident barred from a compliant local exchange faces higher friction converting tokens into spendable funds, even though the tokens themselves remain transferable on-chain. The notice is best read as a demonstration of where state authority over money is actually enforceable, at the border between a network and a banking system, rather than as a claim that any government can unilaterally rewrite a shared ledger's rules.

• Which parts of a described token arrangement are enforceable against local institutions, and which exist only on a network no single jurisdiction controls?
• If on-ramps and off-ramps are closed in one jurisdiction, what alternative route converts the asset to local currency, and at what cost?
• Does a jurisdictional ban change a token's on-chain validity, or only who can legally trade it within that jurisdiction?

A ban on token financing is a ban on the businesses and banks that touch it, not a technical rollback of a protocol. The distinction between network rules and jurisdictional rules is exactly the boundary this notice drew, deliberately, in its own text.
