đ Ethereum's Dencun upgrade is bringing exciting changes with EIP-4844! đ„
đ€ Ethereum currently has 2 types of transactions, but EIP-4844 introduces a new type-3 transaction called protodanksharding. đĄ EIP-4844 creates "blobs" - large data packets that can be used by Layer 2 (L2) networks to settle transactions on Ethereum's mainnet. đ° This helps reduce the high costs associated with posting L2 data through Ethereum's calldata, which L2s currently use.
đŠ Each block can have up to 6 blobs, and each type-3 transaction can have 1 or 6 blobs, storing up to 128kb of data. â±ïž Blobs are only stored for around 18 days, making them cheaper than calldata, which is stored forever. đ§ EIP-4844 also introduces new transaction and block header fields to manage the blob gas market, similar to EIP-1559.
đ€ This change is expected to substantially reduce posting costs for L2 networks, transforming the market. đ However, L2 operators will need to monitor both the type-2 and type-3 fee mechanisms to determine the most advantageous option.
Thus, this Ethereum upgrade will only reduce the fees for layer 2 and not the Ethereum gas fee itself.đ
