Abstract
Meter the bytes each opcode adds to the EIP-7928 Block Access List in an explicit per-transaction counter, and fold that count, at 64 gas/byte, into the transaction's floor accumulator — checked at runtime before the BAL grows. Today an attacker can pack ~1.55 MB into a 60M-gas block: 75% of gas on cold SLOADs (32 BAL bytes per 2,100 gas) + 25% on calldata at 16 gas/byte. On top of EIP-8131's…
