Summary

We should implement blob compression before submission to reduce bandwidth usage, storage costs, and improve overall performance of the EV node network.

##Motivation

Currently, blobs are submitted without compression, which leads to:

• Higher bandwidth consumption during blob submission
• Increased storage requirements
• Slower transmission times, especially for larger blobs
• Higher operational costs for node operators

Proposed Solution

Implement a compression layer that automatically compresses blobs before submission while maintaining compatibility with the existing blob format.
Key Requirements:

Compression Algorithm: Consider using efficient algorithms like:

• LZ4 for fast compression/decompression with moderate compression ratios
• zstd for balanced performance and compression ratio
• gzip for maximum compatibility

Backward Compatibility: Ensure compressed blobs can be properly handled by existing nodes
Metadata Handling: Include compression metadata in blob headers:
