Ethereum’s core development team has rolled out the Fusaka upgrade, adding Data Availability Sampling and enabling independent blob‑parameter‑only (BPO) forks. The network now supports 14-21 blobs per block, a 2.3× increase in L2 data capacity. Two BPO forks were successfully stress‑tested and deployed, with a third pending only if blob usage rises. Progress continues on the upcoming Glamsterdam fork, where Proposer‑Builder Separation (ePBS) and Block‑level Access Lists (BALs) are being staged on devnets; ePBS remains the more complex element. The next major upgrade, Hegotá, is fully scoped, with its headliners and the FOCIL censorship‑resistance proposal slated for February 4.
