Overview

revm - Revolutionary Machine

Is Rust Ethereum Virtual Machine with great name that is focused on speed and simplicity. It gets ispiration from SputnikVM (got opcodes/machine from here), OpenEthereum and Geth with a help from wolflo/evm-opcodes. This is probably one of the fastest implementation of EVM, from const EVM Spec to optimistic changelogs for subroutines to merging eip2929 in EVM state so that it can be accesses only once are some of the things that are improving the speed of execution.

Here is list of things that i would like to use as guide in this project:

EVM compatibility and stability - this goes without saying but it is nice to put it here. In blockchain industry, stability is most desired attribute of any system.
Speed - is one of the most important things and most decision are made to complement this.
Simplicity - simplification of internals so that it can be easily understood and extended, and interface that can be easily used or integrated into other project.
interfacing - [no_std] so that it can be used as wasm lib and integrate with JavaScript and cpp binding if needed.

For more INFO check

Please check bins/revm-test for simple use case.

All ethereum state tests can be found bins/revm-ethereum-tests and can be run with cargo run --release -- all

Pre EIP-2 support

I'm working on adding support to revm for pre-BYZANTIUM spec's and encountered a issue with the library design that I am unsure the right way to solve.

For context, pre EIP-2 / HOMESTEAD (https://eips.ethereum.org/EIPS/eip-2) a transaction that creates a contract and runs out of gas succeeds but creates a zero length / empty contract. Example transaction: https://etherscan.io/tx/0x6e5c7be761ce29049f8d97d5ecde95758c546e9b8121fe421c99730d32e77a47

I initially tried the following (its a little ugly workaround):

+                            let code_hash =
+                                H256::from_slice(Keccak256::digest(&empty_contract).as_slice());
+                            self.data.subroutine.set_code(
+                                created_address,
+                                empty_contract,
+                                code_hash,
+                            );
+                            return (Return::Continue, ret, interp.gas, b);
+                        }
                     }
                 }
                 // if we have enought gas

But during the db.commit() phase it still triggers the Account::is_empty() to be true and the account to be destroyed. Unfortunately both the Account and DatabaseCommit traits don't currently have access to the SPEC. Is there a better place I could try to prevent the contract from being deleted if emulating pre-HOMESTEAD?

Additional Question:

I am interested in full Ethereum chain historic emulation so I am happy to create a PR for pre-BYZANTIUM spec changes I am making, but I wanted to check: is this something you're interested in supporting?

Thanks!

feat: Introduce ByteCode format
With a restriction that contacts can not start with 0xEF and with the possibility that in future we will have different ByteCode for EVM Object Format, it makes sense to introduce support for it into the revm. https://eips.ethereum.org/EIPS/eip-3541

The biggest benefit atm would be introducing ByteCode type that will contain jumptable and gas blocks and with that we would skip the needed analysis of the contract. This is a fairly big speed-u for some use cases noticed in the foundry as fuzzing tests call a lot of contracts with not much execution and analysis, in that case, is taking a lot of time.

The proposal is to introduce enum ByteCode that would somehow return: code, code_size and jumptable.

Basically replace this input with ByteCode: https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/interpreter/contract.rs#L60 and propagate change wherever needed. ByteCode should set these fields in the contract:

https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/interpreter/contract.rs#L11-L13

https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/interpreter/contract.rs#L21

and do the same for database struct:

Return ByteCode: https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/db/traits.rs#L14

Replace bytes with BytesCode: https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/models.rs#L24

To fully circle the story with EVM Object Format, CREATE and CREATE2 will need to return 0xEF type format in bytes that would get transformed to ByteCode for evm usage here:
https://github.com/bluealloy/revm/blob/08528247759bcd113c0c5385ee081e20e11cb80b/crates/revm/src/evm_impl.rs#L395-L399 But this is a consensus rule and out of scope for this feat, we should just continue using legacy ByteCode here. If needed we could in Inspector create_end transform that into ByteCode.

Tx unexpectedly reverts with "out of gas" reason

Hi,

When processing the below tx with the revm I get an out of gas revert? https://snowtrace.io/tx/0x5d9999e9e8ccdea2d87736cc39c38f51863f6f23169ac32ef2d9a1842aa94c23

Gas limit on the tx is 348,243 and gas used is 348,243. Seems strange to me that it fails with revm but doesn't fail on avalanche? Avalanche just use a copy of geth for this stuff afaik.

Benchmark against other EVMs

It would be cool to benchmark against other EVM implementations, especially evmone which AFAIK is currently the fastest EVM interpreter.

This would probably be a good benchmark for arithmetic: https://github.com/ethereum/evmone/pull/320

revm: Return `bytes` in Create calls

In create_inner, let b = Bytes::new(); was always returned, without ever being touched. The create calls should return the deployed contract bytecode.

This might relate to https://github.com/bluealloy/revm/issues/269 ?

don't delete account and storage entries on commit
As discovered here https://github.com/foundry-rs/foundry/issues/1894

deleting storage or account entries does not play nice with fork mode which basically does:

if !db.contains(acc) { // fetch from remote }

So deleting accounts/slots (when empty) would result in the fork's account/slot being served and not 0 or the empty account.

Solution

on CacheDb::commit don't delete AccountInfo or storage entries in the CacheDb's maps

also bumps to v1.6.0

feat(interpreter): Unify instruction fn signature

All opcode instructions are now functions with same signature: pub fn jumpi(interpreter: &mut Interpreter, _host: &mut dyn Host)

This is revm internal change and it does not affect external API.

This allows the compiler to optimize calls in the interpreter hot loop and it gives around ~10% faster snailtracer execution on i7. I am interested to see if the same boost can be found on macs with M processors.

This is one of steps needed to define multiple dispatch strategies related to interpreter loop. As instructions now have same signature they can be put in an array, this can have potentially new ways to use revm as it is easier to just switch function pointer to something else (custom function to sload/sstore?)

Spec was simplified and is_static is moved as variable to interpreter (Previously it was inside Spec)

There was one regression with ruint in casting U256 to saturated usize here. It was faster to just check limbs.

microbench added to revm-tests

fix: remove stipend from sstore gas calculations
Not sure what the reasoning was for including the stipend for SSTORE originally. Couldn't find any other EVM implementations doing this check.

Encountered the issue when testing a number of scenarios using cast.

Specifically:

cast run 0x10c305ada9cb1066b396d6558d1d195d21abfaef6c76e5ae1568354b58daab64

The transaction would fail due the storage slot of the reentrancy guard being reset.

New dispatch strategy: Add array of instruction handles

I experimented a little bit with this, as in having [InstructionFn;256] but I had a lot of changes and I am not sure if this was good for perf or not. Either way having this Array can be beneficial in multiple ways as in adding custom handles that could potentially replace the inspector, or allowing an additional ways to access the internal state of the interpreter.
