Abstract: A method and a system for managing voting of an alliance chain based on variable strategies are provided. The method specifically includes: 1) classifying channel strategies into an implicit strategy and a strategy based on signature; 2) specifically implementing the variable strategies: initiating, by a user, a proposal request for modifying a strategy; detecting whether a content of the strategy meets a format requirement on the condition that a target strategy is a strategy based on signature; sending a voting invitation or a signature invitation to an organization requiring auditing according to a present channel strategy or a present network strategy; voting or signing by the invited organization; analyzing a result to determine whether the result meets a requirement of the present channel strategy; if so, modifying the present channel strategy to a target channel strategy; otherwise, failing in modification.
