1. U.S. January PPI Monthly Increase of 0.5% Exceeds Expectations

The U.S. Producer Price Index (PPI) for January rose by 0.5% month-over-month, surpassing the expected 0.30%. The previous figure was revised from 0.50% to 0.4%. The annual PPI for January was 2.9%, also higher than the expected 2.60%, with the previous reading at 3.00%. AI Analysis: The PPI data exceeding market expectations indicates ongoing inflationary pressures. This result will increase market expectations for future Federal Reserve rate hikes, especially given that inflation has not declined as significantly as anticipated. The rise in PPI may also influence consumer prices, further transmitting to the CPI and reinforcing inflation persistence.

3. Korean Tax Authority Leaks Mnemonic, $4.8 Million in Cryptocurrency Stolen

On February 26, the Korean National Tax Service released news footage of a raid targeting 124 high-value, habitual tax delinquents, accidentally revealing a photo containing the mnemonic for a seized Ledger hardware wallet without any mosaic censorship. Blockchain expert 조재우 (Jaewoo Cho) pointed out that after the mnemonic was leaked, 4 million PRTG tokens stored in the wallet were transferred to an unknown address early on the 27th, with an estimated loss of about 6.4 billion Korean won (approximately $480,000). Analysis shows the thief first deposited a small amount of Ethereum as a fee, then transferred all tokens in three transactions.

4. Vitalik Buterin Explains Ethereum Scaling Plans

Ethereum co-founder Vitalik Buterin posted a scaling 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 ePBS functionality. Additionally, a multi-dimensional Gas mechanism will add a “state creation Gas” dimension, not counting toward the approximately 16 million transaction Gas limit, allowing for larger contracts. The EVM will handle multi-dimensional Gas consumption through a “reserve pool” mechanism and maintain two invariants. Long-term scaling includes ZK-EVM and Blobs. Blobs will be iterated through PeerDAS, aiming for about 8 MB/sec data processing capacity, with future block data directly entering Blobs. ZK-EVM will be phased in, allowing validators to use ZK-EVM clients by 2026, with broader network deployment recommended by 2027, ultimately moving toward a 3-of-5 proof mechanism where all nodes (except index nodes) rely on ZK-EVM proofs.
