<!-- в чем причина правок? тоесть понятным образом обьясняешь что не так было до наших правок --> Previously kvcache used hash.Hash.Sum incorrectly when computing code cache keys, passing a preallocated 32-byte slice and ignoring the returned slice. As a result all code entries were effectively cached under the all-zero key and OnNewBlock pre-population of the code cache did not work as intended. <!-- Четкое и лаконичное общее описание изменений, вносимых этим PR --> Use the Sum(nil) result as the code hash key for UP SERT_CODE and CODE actions in OnNewBlock, so each bytecode is cached under its real Keccak-256 hash while avoiding the extra make([]byte, 32) allocation.
