Cursor released the third-generation programming model Composer 2 on March 20, with prices significantly reduced to $0.50 per million input tokens and $2.50 per million output tokens, while also launching a fast version. Composer 2 performs better than its predecessor in multiple benchmark tests, but falls short of GPT-5.4, with improvements mainly coming from continued pretraining of the base model and reinforcement learning. The model is exclusively available for Cursor's internal use, while its parent company Anysphere has a valuation of $29.3 billion.

Ethereum akan memperkenalkan "Fast Confirmation Rules" (FCR) pada 18 Maret, meningkatkan efisiensi transfer aset dari Layer 1 ke Layer 2, dengan waktu konfirmasi diperpendek hingga sekitar 13 detik. Mekanisme ini direalisasikan melalui "fast confirmation blocks", meningkatkan throughput jaringan dan pengalaman pengguna tanpa mengorbankan keamanan, diperkirakan akan mendorong adopsi solusi L2. Tidak memerlukan hard fork, menyederhanakan proses penyebaran.
