EIP‑7825 proposes a protocol‑enforced cap of 30 million gas per transaction, regardless of the overall block gas limit, to prevent individual transactions from consuming excessive block resources. This cap aims to improve network stability and guard against denial‑of‑service risks, especially as Ethereum evolves toward higher block gas limits and more complex transaction patterns. It also helps enhance parallel execution and rollup batching, ensuring that a single oversized transaction doesn’t bottleneck block processing.

EIP‑7934 proposes adding a protocol-level cap on the RLP-encoded size of execution-layer blocks, currently set at 10 MB plus a 512 KB margin, to prevent oversized blocks that strain network infrastructure. This cap addresses risks around network instability, such as slow block propagation, increased validation times, and potential consensus issues or DoS threats. While Ethereum already limits block processing by gas, explicitly bounding block bytes improves predictability and resilience in high-throughput scenarios or when adjusting gas limits upward.
