Sui represents a significant evolution in blockchain architecture, moving away from account-based models to an object-centric model which enables massive parallelism. With over 7k stars and an exceptionally high fork count (11k+), it has established deep ecosystem gravity. As a foundational L1 infrastructure with its own programming language ecosystem (Move), the switching costs are high and the technical moat is deep. Frontier AI labs are focused on compute and intelligence, making the risk of direct competition in the L1 space negligible.
