Ethereum Gas Economics Overhaul Targets Scalability and Security

The Ethereum network has undergone significant changes to its gas economics in a bid to improve scalability and prevent DoS attacks. The calldata floor cost has increased to 64 gas per byte, affecting about 1.5% of transactions that use large data payloads. This change aims to target data-heavy transactions with minimal EVM computation. Regular users performing token transfers or DeFi operations will still pay the standard 4/16 gas rate.

The Ethereum Improvement Proposals (EIPs) have also introduced new limits, including a maximum transaction gas of 16,777,216 and a default block gas limit of 60 million. The EVM computation costs have been adjusted to better reflect the computing power required for certain inputs. For example, the MODEXP charge has been increased from 200 to 500 gas, and large base or modulus inputs now trigger higher costs.

PeerDAS, a data availability scaling solution, has expanded blob capacity by 8x through Reed-Solomon encoding. This allows nodes to hold only a portion of blob data, reducing bandwidth requirements. The network divides into 128 subnets, each storing a fragment of the overall blob data.
