Ethereum Decun Update: breakdown

EIP-4844 (Proto-Danksharding) is one of Ethereum’s most significant updates, implemented within the recent Dencun upgrade. It dramatically reduced transaction costs on L2 and became a major step towards Ethereum's data sharding. Igor Mandrigin from Gateway.fm (formerly Erigon, Status, Opera developer) dives deep into what exactly has changed in Ethereum and explains what blobs are.

• 🔹 Why the Dencun update (EIP-4844) significantly lowered fees on Layer-2 networks but didn't drastically affect Ethereum Mainnet fees.
• 🔹 What blobs are, why Ethereum introduced a new data storage solution, and why blobs have an 18-day lifespan.
• 🔹 What polynomial KZG commitments are and why Ethereum chose them for blob verification and data storage.
• 🔹 The difference between Blobspace and Blockspace, and how it impacts Ethereum’s architecture and economics.
• 🔹 Technical details behind Proto-Danksharding implementation, infrastructure impact, and Ethereum node performance.
• 🔹 How Proto-Danksharding paves the way for full Ethereum data sharding and the stages ahead.
• 🔹 Why Ethereum's future involves many specialized L2 solutions and how blockchain ecosystems will evolve.
