Eurocode ZB: ZB has 7 senior executives who manage the private key.

"Golden Century Talks | Security Care: What can CEX do for clients?" During the show, Ouma introduced the security mechanism of the ZB wallet. Ouma said the ZB portfolio uses a combination of refrigeration and thermal separation. Most of the money is stored in offline wallets, and only around 0.5% of crypto devices are stored in the wallet for daily operations. To provide additional protection, crypto wallets are not accessible by any platform or platform servers. Among them, the offline wallet is the most important part of the security exchange, and ZB ZB has a total of 7 big leaders (all outside of China) who manage the private cooling wallet using multiple systems of signature. Since only one person has the keys to self-control and finances, they can reduce black swan incidents that occur during a trade.
