Unanimous voting refers to a decision-making process where all participants in a network must agree on a particular outcome. In cryptocurrency systems, it typically involves network participants, known as nodes, coming to a complete consensus before a change can be implemented.This method ensures high security and trust, as no single participant can sway the decision without the agreement of others. It is often found in governance mechanisms for blockchain projects, allowing stakeholders to vote on proposals such as upgrades or changes to protocols.While unanimous voting can enhance security, it can also introduce challenges. Achieving full agreement can be difficult, leading to delays in decision-making. This requirement may limit the speed at which a network can adapt to new information or changing circumstances.Overall, unanimous voting aims to create a robust and trusted environment by ensuring that all voices are heard before any action is taken.
