The chain reset
Real talk: the Zano blockchain just hit the undo button on an entire month of history. After a nasty exploit involving a feature called Gateway Addresses allowed hackers to mint unauthorized ZANO and Freedom Dollar (fUSD) tokens, the core team decided to restart the chain at block 3,833,000.
That block height is the exact point right before "Hard Fork 6," which introduced the compromised feature. By rolling back to this point, the team aims to scrub the fake coins from existence and protect the token's fixed supply. But there is a massive catch: this move wipes out every single legitimate transaction that occurred over the last month. If you were active on-chain during that window, those transactions are essentially gone on the recovered chain.
The fallout
The team is currently asking nodes, miners, stakers, and exchanges to jump on board with the update to finalize the recovery. As for the folks who got caught in the crossfire of this rollback, the team says they are working on a reimbursement and claims process. However, they acknowledged that payments already settled on other blockchains are effectively out of reach.
"Doing nothing meant unauthorized ZANO and fUSD in circulation without limit, diluting every holder and breaking the most basic promise a currency makes: a fixed supply," explained Quinten van Welzen, Zano’s head of marketing and growth.
Why it matters
This is a classic 'lesser of two evils' situation. While losing a month of on-chain activity is a major L, the alternative was letting the exploit dilute the entire supply, which basically guarantees a project goes to zero. It’s a sobering reminder that even in privacy-focused layer-1 chains, smart contract vulnerabilities can leave everyone holding the bag. Always remember: in crypto, the tech is experimental and the risks are real—never invest more than you can afford to lose. This is definitely not financial advice.
