The Zano blockchain has been restarted at the block height that came immediately before Hard Fork 6, which introduced Gateway Addresses.
The Zano blockchain has been restarted at the block height that came immediately before Hard Fork 6, which introduced Gateway Addresses.
Zano has rolled back approximately a month of blockchain history after a vulnerability involving Gateway Addresses allowed unauthorized ZANO and Freedom Dollar to enter circulation, according to its core team.
The Zano blockchain has been restarted at block 3,833,000, immediately before Hard Fork 6, which introduced the affected feature. The recovery requires participating nodes, miners, stakers, exchanges and other services to adopt the update, the team said Sunday.
Zano has not released a post-mortem at the time of publication, but confirmed the issue came from Gateway Addresses, a feature developed to make it easier for bridges, exchanges and payment services to integrate with Zano by letting them manage funds through a single account-style balance (similar to other blockchains).
