SSZ

Ethereum developers are proposing a shift from the aging RLP encoding to the modern SSZ format in EIP-7807. While promising better performance and type safety, the move risks consensus splits in a $300 billion network.

A new EIP proposes SSZ Compact Multiproofs to slash Ethereum Merkle proof bandwidth by up to 60%. While technically elegant, the proposal must compete for scarce developer resources against high-impact upgrades like Verkle trees.
