Abstract generation in progress

The Ethereum network just rolled out another round of critical consensus layer improvements during the 172nd meeting of the core development team. Here’s what actually matters from the technical updates.

BPO2 Activation: The Green Light

Ethereum developers successfully activated BPO2, marking another milestone for the network’s stability and performance. This wasn’t just a routine flip—it represents months of testing and validation across the consensus layer infrastructure.

Blob Handling Gets More Generous

One of the biggest changes? The Blob Target went live at 14, while the Limit jumped to 21. For those tracking Layer 2 scaling, this is significant because it directly impacts how much data can be batched on-chain. More blob capacity means smoother throughput for rollups building on top of Ethereum.

EIP-8070: Sparse Blob Pool Confirmed for Glamsterdam

The community confirmed that EIP-8070—also known as the Sparse Blob Pool proposal—will be included in the Glamsterdam upgrade. This improvement optimizes how the network manages blob storage and retrieval, reducing unnecessary data bloat in the consensus layer.

Timeline Alert: Hegota Proposal Deadline February 5

Developers have opened up the proposal process for Hegota, with a firm deadline of February 5 for submissions. This is shaping up to be another substantial consensus layer evolution to watch.

The takeaway? Ethereum’s consensus layer keeps getting stronger, more efficient, and better equipped to handle the network’s explosive growth.
