According to PolkaWorld's Polkadot Weekly, Gavin Wood recently released the 2024 annual summary, and believes that 2023/2024 is a watershed for Polkadot, and its core goals have undergone a clear shift. From focusing on achieving the limited range of product goals in the white paper, it has shifted to optimization, stability improvement and product refinement to better meet market needs. Technically, many major advances have been proposed and implemented in 2024; ecologically, projects represented by Mythical Games are pushing Polkadot performance to the limit; in addition, Gavin also proposed JAM in 2024 to further realize his Web3 vision. All in all, 2025 is worth looking forward to. In addition, Gavin proposes Proof-of-Personhood, a mechanism to be rolled out in 2025, which aims to be an antidote to the threat posed by generative AI to the free world. It provides trusted identity solutions for Web3 and Web2 through algorithmic "personality" concepts combined with ZK technology to protect privacy.
