Abstract
Improvements of blockchain-based user accounts in terms of user security and control are presented. For instance, there is provided a computer-implemented method comprising providing a blockchain-based user account for a user, wherein the user account is associated with a first private key for performing a user operation on a blockchain network, the first private key maintained on a device associated with the user, and wherein the user account is further associated with a second private key and a third private key for collaboratively configuring one or more execution conditions for the user operation, the second private key maintained on the first device and the third private key maintained on a second device, wherein the first device and the second device are devices associated with the user. A corresponding system including at least the first device and the second device and a corresponding method performed at a validator node are also provided.
