Zano rolls blockchain back a month after Gateway Address exploit

Cointelegraph reports Zano rolled its chain back a month after a Gateway Address exploit; here is what compliance teams should do while details are thin.

Cointelegraph reports that Zano rolled its blockchain back a month following what it calls a Gateway Address exploit. At the time of writing, the headline is the only detail Cointelegraph has published: no figures, dates, addresses, or names have been confirmed beyond it.

Why a rollback matters to this work

A blockchain rollback reverts the ledger to a state before a disputed set of transactions. For anyone tracing funds, that means the chain history you pull today may not match the chain history that existed a month ago on the same network. Wallet balances, transaction hashes, and address activity can all shift once a rollback executes.

For compliance analysts and investigators, this creates a practical problem before it creates an evidentiary one: which version of the chain is the record of truth for a given case, and when did that version become final. Cointelegraph's report does not say how Zano is handling that question, so it should not be assumed either way.

What to do right now

• Treat the Cointelegraph headline as the only confirmed fact until a fuller report or Zano statement adds detail.
• Do not attribute the exploit to any individual, group, or organisation beyond what is stated in the reporting.
• If you hold Zano exposure on a case, note the timestamp of any chain data you pull now, since a rollback can change what that data shows later.
• Watch for a follow-up from Cointelegraph or Zano itself before updating client-facing risk assessments.

Only the headline is known right now. Any figures, dates, or names beyond it are not part of this story yet.
