Answer: After 1 day, the vault and all users would remain locked in and unable to withdraw funds. This could be a major issue for businesses and individuals that rely on the vault for their financial security and operations. To prevent this from happening, it is important to ensure that all users have access to the vault and are able to withdraw funds when necessary. This can be done by setting up a system of checks and balances, such as requiring multiple signatures to approve withdrawals, or setting up a secure login system with passwords and/or biometrics. Additionally, it is important to regularly review and update the security protocols to ensure they are up to date and effective. By taking these measures, businesses and individuals can be sure that their funds are secure and accessible when needed.
