From eb67d6193344db0a11cb6b344e4ad781e07bc51f Mon Sep 17 00:00:00 2001 From: rjl493456442 Date: Tue, 14 Apr 2026 21:54:36 +0800 Subject: [PATCH] cmd/geth, core/state, tests: rework EIP7610 check (#34718) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR simplifies the implementation of EIP-7610 by eliminating the need to check storage emptiness during contract deployment. EIP-7610 specifies that contract creation must be rejected if the destination account has a non-zero nonce, non-empty runtime code, or **non-empty storage**. After EIP-161, all newly deployed contracts are initialized with a nonce of one. As a result, such accounts are no longer eligible as deployment targets unless they are explicitly cleared. However, prior to EIP-161, contracts were initialized with a nonce of zero. This made it possible to end up with accounts that have: - zero nonce - empty runtime code - non-empty storage (created during constructor execution) - non-zero balance These edge-case accounts complicate the storage emptiness check. In practice, contract addresses are derived using one of the following formulas: - `Keccak256(rlp({sender, nonce}))[12:]` - `Keccak256([]byte{0xff}, sender, salt[:], initHash)[12:]` As such, an existing address is not selected as a deployment target unless a collision occurs, which is extremely unlikely. --- Previously, verifying storage emptiness relied on GetStorageRoot. However, with the transition to the block-based access list (BAL), the storage root is no longer available, as computing it would require reconstructing the full storage trie from all mutations of preceding transactions. To address this, this PR introduces a simplified approach: it hardcodes the set of known accounts that have zero nonce, empty runtime code, but non-empty storage and non-zero balance. During contract deployment, if the destination address belongs to this set, the deployment is rejected. This check is applied retroactively back to genesis. Since no address collision events have occurred in Ethereum’s history, this change does not alter existing behavior. Instead, it serves as a safeguard for future state transitions. --- cmd/geth/snapshot.go | 108 +++++++++++++++++++++++++++++ core/state/statedb.go | 3 + core/state/statedb_hooked.go | 4 -- core/state/statedb_test.go | 16 ++--- core/state/trie_prefetcher_test.go | 5 +- core/vm/eip7610.go | 98 ++++++++++++++++++++++++++ core/vm/eip7610_test.go | 62 +++++++++++++++++ core/vm/evm.go | 3 +- core/vm/interface.go | 1 - tests/block_test.go | 12 ++++ tests/state_test.go | 11 +++ 11 files changed, 304 insertions(+), 19 deletions(-) create mode 100644 core/vm/eip7610.go create mode 100644 core/vm/eip7610_test.go diff --git a/cmd/geth/snapshot.go b/cmd/geth/snapshot.go index c177fb5ea2..d168ee1d7d 100644 --- a/cmd/geth/snapshot.go +++ b/cmd/geth/snapshot.go @@ -18,15 +18,18 @@ package main import ( "bytes" + "encoding/hex" "encoding/json" "errors" "fmt" "os" "slices" + "sort" "time" "github.com/ethereum/go-ethereum/cmd/utils" "github.com/ethereum/go-ethereum/common" + "github.com/ethereum/go-ethereum/core" "github.com/ethereum/go-ethereum/core/rawdb" "github.com/ethereum/go-ethereum/core/state" "github.com/ethereum/go-ethereum/core/state/pruner" @@ -168,6 +171,22 @@ block is used.
