Abstract

This EIP adds a gas penalty for accesses to the account trie, where the address being looked up does not exist. Non-existing accounts can be used in DoS attacks, since they bypass cache mechanisms, thus creating a large discrepancy between 'normal' mode of execution and 'worst-case' execution of an opcode.
