The tzsign multisig appears to be working again, as testing is currently underway in the mainnet. This is great news for users of the Tezos blockchain, as the multisig feature provides an extra layer of security and allows users to create and manage multiple signatures for their accounts. With this feature, users can create and manage multiple signatures for their accounts, allowing them to securely sign transactions and manage their funds. This is especially useful for businesses and organizations that need to manage multiple accounts, as it allows them to easily manage access rights and permissions. Additionally, the multisig feature allows users to set up custom thresholds for approving transactions, allowing them to have greater control over their funds and transactions. Overall, the tzsign multisig feature is a great addition to the Tezos blockchain, providing users with an extra layer of security and control.
