The transformation of Tezos did not involve any dramatic events, but rather consisted of years of continuous iteration behind the scenes. Each carefully designed upgrade plan was implemented step by step, and by the time the milestone in Paris occurred, the entire ecosystem had already changed completely.

What is the most critical change? The era where pure bakers acted as guardians of security has evolved into a hybrid model where both bakers and native stakers jointly protect it. This not only means that there are more participants, but more importantly, the underlying logic of the entire economic incentive system has undergone a fundamental reshaping.

It turns out that only bakers need to lock in real rights to maintain the security of the chain. Now, stakers can directly lock in their rights at the protocol layer, fighting alongside bakers. It sounds like a simple adjustment of division of labor, but in reality, this is a deep reconstruction from the perspective of game theory—under a multi-participant model, the incentive mechanisms for each role have been rebalanced.

Why do this? Because the vulnerabilities of a single security model are evident. A diversified participation mechanism means that the cost of attacks significantly increases, and the economic foundation is more stable. Tezos has demonstrated what true self-improvement means through its actions in this evolution of protocols.
