4. Blob Transaction Pool Conversion (24 September 2025)
Overview: This change ensures that existing blob transactions in a node's memory pool are automatically converted to a new format at the Osaka fork boundary. It's designed to be a seamless process that prevents user transactions from being dropped during the upgrade.
What this means: This is bullish for Ethereum because it prioritizes user experience and network stability during a protocol change. Smooth upgrades reduce friction for everyone using the chain, from everyday users to application developers.
