1. US January PPI monthly rate of 0.5% exceeds expectations
The US Producer Price Index (PPI) for January recorded a monthly rate of 0.5%, higher than the expected 0.30%, with the previous value revised from 0.50% to 0.4%. The year-on-year PPI for January was 2.9%, also above the expected 2.60%, while the previous value was 3.00%. AI interpretation: The PPI data exceeded market expectations, indicating that inflationary pressures still exist. This result will increase market expectations for future interest rate hikes by the Federal Reserve, especially against the backdrop of inflation not significantly retreating as anticipated. The rise in PPI may also affect consumer prices, further transmitting to CPI, reinforcing the persistence of inflation. -Original

3. South Korea's National Tax Service leaks mnemonic words, $4.8 million in cryptocurrency stolen
The South Korean National Tax Service accidentally revealed photos containing the seized mnemonic words for the Ledger hardware wallet in the news release regarding a site search of 124 high-value, habitual tax evaders issued on February 26, without any pixelation. Blockchain data expert 조재우 (Jaewoo Cho) pointed out that after the mnemonic words were leaked, 4 million PRTG tokens stored in that wallet were transferred to an unidentified wallet in the early hours of the 27th, resulting in a loss of approximately 6.4 billion Korean won (about $4.8 million). Analysis shows the thief first deposited a small amount of Ethereum into the wallet as a fee, then transferred all tokens in three transactions. -Original
4. Vitalik Buterin outlines Ethereum scalability plans
Ethereum co-founder Vitalik Buterin released a scalability plan on social media, covering short-term and long-term goals. In the short term, the Glamsterdam upgrade will introduce block-level access lists for parallel validation and launch the ePBS feature. At the same time, a multi-dimensional Gas mechanism will add a "state creation Gas" dimension, which is not counted toward the approximately 16 million transaction Gas limit, allowing the creation of larger contracts. The EVM will handle multi-dimensional Gas consumption through a "reserve pool" mechanism and maintain two invariants. Long-term scalability includes ZK-EVM and Blobs. Blobs will iterate through PeerDAS, aiming to achieve about 8 MB/second data processing capability, with future block data going directly to Blobs. The ZK-EVM will be advanced in phases, allowing validators to use the ZK-EVM client in 2026, recommending more networks to run ZK-EVM in 2027, and ultimately shifting to a 3-of-5 mandatory proof mechanism, where all nodes (excluding index nodes) will rely on ZK-EVM proof. -Original
