Largest mining difficulty drop since 2021
Mining difficulty fell 11.16% at block 935,424, the largest drop since China's mining ban in 2021, after a US winter storm and falling prices led miners to switch off machines. It rose 14.7% at the next adjustment, on 19 February.

Quantum-resistance proposal BIP 360 is merged
BIP 360, a proposed new output type called Pay to Merkle Root (P2MR) that would not reveal public keys when coins are spent, was merged into the Bitcoin Improvement Proposals repository. It is meant as a first step towards protecting bitcoin from future quantum computers; merging records it for review and changes nothing on the network.
