On January 27, Solana co-founder Toly updated his Twitter profile picture to a Penguin-themed concept image. Per GMGN monitoring (link: https://gmgn.ai/sol/token/i_m4TE56o8_8Jx8AAHj86wbQgUTjGuj6GTTL5Ps3cqxKRTvpaJApump), this news may have sparked a temporary surge of over 17% in **PENGUIN**, a Solana-based meme coin.

On January 27, Vitalik published a post outlining blockchain scalability’s core hierarchy: computation, data, and state. Computation is the easiest to scale. It can be parallelized, and block producers can either provide verification hints or replace large-scale arbitrary computation with proofs of the result. Data sits in the middle. If data availability is required, that guarantee is unavoidable—but data can be sharded and erasure-coded. There’s also "progressive degradation": a node with just 1/10 the data processing power of others can still produce blocks 1/10 the size of typical blocks. State is the hardest to scale. Even validating a single transaction requires the full state. Replacing state with a tree and keeping only the root hash still demands the complete state to update that root. While state sharding exists, it requires architectural overhauls and fundamentally lacks generality. His key takeaway: If you can replace state with data without new centralization r
