From f5db50814fc903b9174b1af7d9bbf477134a1180 Mon Sep 17 00:00:00 2001 From: Ming Date: Mon, 30 Oct 2023 20:11:13 +0800 Subject: [PATCH 01/13] [proof chunk] refactor evm_circuit/state_circuit to support proof chunk (#1641) ### Description [_PR description_] ### Issue Link #1601 ### Type of change - [ ] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [x] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] This change requires a documentation update ### Highlights - separate rw_table in evm_circuit/state_circuit and each have its own permutationchip. fingerprints checking will be deferred to root circuit. - disable rwtable first row check (by disable selector offset=0 in state_circuit, other offset toggle on as usual), since it will be copy constraints via public input. - keep `Rw::Start` and introduce `Rw::Padding` to support post-padding in address-sorted rwtable in last_chunk. - instance (new public input) column are design into two, one for prev_chunk context, another for current_chunk context to be used for next chunk. So in root circuit commitment of instance column can be used in snark-verifier without need to unwrap it. > Update on 18 Oct 2023: beginchunk/endchunk virtual step, inner_rw_counter, chunkctx - add Begin/EndChunk virtual step. BeginChunk is not mandatory in first chunk first step. while EndChunk is not mandatory in last chunk last step. - add `inner_rw_counter` which is local rw_counter within each chunk. This is used to count valid rw_row and assure Rw::Padding are append consecutively in `end_block.rs` logic => EndChunk should apply similar check later on - introduce chunkctx->{chunk_index, total_chunks} to tell first chunk (chunk_index==0) and last chunk (chunk_index + 1 == total_chunks) during witness generation/constraints assignment - add chunkctx_table to able to lookup chunk context (chunk_index, next_chunk_index, total_chunk, initial_rwc, end_rwc..etc) in exec step to allow various conditional check based on current chunk context ### How Has This Been Tested? [_explanation_] ### More context on Rw::Padding (Not cover in current PR, will be handled in later multiple chunk PR to make scope smaller) In new logic, `Rw::Start` will be insert in first chunk offset 0, while other holes are filled by `Rw::Padding` in last chunk(s). The address-sorted rwtable layout will be ``` address-sorted rwtable ## first chunk [ Rw::start, // offset 0, Rw::Start is only in first chunk, and only in offset 0, constrainted by public input ....(normal Rw), ...(Rw::Padding), // padding if there are only one chunk ] ## end chunk (if there are > 1 chunk) [ ....(normal Rw), // offset 0 are carry over from previous chunk, other are address sorted ...(Rw::Padding) // padding in end chunk ] ``` For chronologically rwtable, since there is no in-row constraints to check each Rw operation, so theoretically Rw::Padding rows can be filled in any offset. However, we also need to assure there is no malicious insertion other than Rw::Padding. To do that, we will rewrite this logic in later PR https://github.com/privacy-scaling-explorations/zkevm-circuits/blob/main/zkevm-circuits/src/evm_circuit/execution/end_block.rs#L86-L90 to lookup consecutive `Rw::Padding` at **chronologically** sorted table, at the END of EACH chunk. > A tricks: first Rw::Padding rw_counter need to be set as last (globally) valid row rw_counter + 1. This is to make sure in both chronologically rw_table or address-sorted rw_table it's always append in the end of rw_table. ``` chronologically rwtable, ascending sorted by `rw_counter`. ## first chunk [ Rw::start, // offset 0, Rw::Start is only in first chunk, constrainted by public input ...(normal Rw), ...(Rw::Padding), // first Rw::Padding rw_counter need to be set as last (globally) valid row rw_counter + 1, last means from last !!chunk!!. It assures Rw::Padding always append at the end of each chunk ] ## end chunk (if there are > 1 chunk) [ ....(normal Rw), // offset 0 are carry over from previous chunk, other are rw_counter sorted ...(Rw::Padding) // padding, also rw_counter sorted ] ``` --- Cargo.lock | 1 + bus-mapping/src/circuit_input_builder.rs | 283 +++++++++++++-- .../src/circuit_input_builder/block.rs | 21 +- .../src/circuit_input_builder/chunk.rs | 57 +++ .../src/circuit_input_builder/execution.rs | 8 + .../circuit_input_builder/input_state_ref.rs | 38 +- bus-mapping/src/exec_trace.rs | 2 + bus-mapping/src/operation.rs | 139 +++++++- bus-mapping/src/operation/container.rs | 69 ++-- circuit-benchmarks/src/state_circuit.rs | 10 +- gadgets/Cargo.toml | 1 + gadgets/src/lib.rs | 1 + gadgets/src/permutation.rs | 314 +++++++++++++++++ zkevm-circuits/src/copy_circuit/dev.rs | 3 +- zkevm-circuits/src/evm_circuit.rs | 332 +++++++++++++++++- zkevm-circuits/src/evm_circuit/execution.rs | 271 +++++++++++--- .../src/evm_circuit/execution/begin_chunk.rs | 72 ++++ .../src/evm_circuit/execution/end_block.rs | 57 +-- .../src/evm_circuit/execution/end_chunk.rs | 108 ++++++ zkevm-circuits/src/evm_circuit/param.rs | 11 +- zkevm-circuits/src/evm_circuit/step.rs | 12 + zkevm-circuits/src/evm_circuit/table.rs | 13 + .../src/evm_circuit/util/common_gadget.rs | 106 +++++- .../evm_circuit/util/constraint_builder.rs | 167 ++++++++- .../src/evm_circuit/util/instrumentation.rs | 4 + zkevm-circuits/src/state_circuit.rs | 197 +++++++++-- .../src/state_circuit/constraint_builder.rs | 25 +- zkevm-circuits/src/state_circuit/dev.rs | 124 ++++++- zkevm-circuits/src/state_circuit/test.rs | 163 +++++++-- zkevm-circuits/src/super_circuit.rs | 11 +- zkevm-circuits/src/table.rs | 28 ++ zkevm-circuits/src/table/chunkctx_table.rs | 145 ++++++++ zkevm-circuits/src/table/rw_table.rs | 28 +- zkevm-circuits/src/test_util.rs | 31 +- zkevm-circuits/src/util.rs | 8 + zkevm-circuits/src/witness.rs | 2 +- zkevm-circuits/src/witness/block.rs | 85 ++++- zkevm-circuits/src/witness/rw.rs | 283 ++++++++++++--- 38 files changed, 2946 insertions(+), 284 deletions(-) create mode 100644 bus-mapping/src/circuit_input_builder/chunk.rs create mode 100644 gadgets/src/permutation.rs create mode 100644 zkevm-circuits/src/evm_circuit/execution/begin_chunk.rs create mode 100644 zkevm-circuits/src/evm_circuit/execution/end_chunk.rs create mode 100644 zkevm-circuits/src/table/chunkctx_table.rs diff --git a/Cargo.lock b/Cargo.lock index d905111ac3..8ba6c5b85a 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1623,6 +1623,7 @@ dependencies = [ "digest 0.7.6", "eth-types", "halo2_proofs", + "itertools", "rand", "rand_xorshift", "sha3 0.7.3", diff --git a/bus-mapping/src/circuit_input_builder.rs b/bus-mapping/src/circuit_input_builder.rs index 754ee6369f..798036f3d8 100644 --- a/bus-mapping/src/circuit_input_builder.rs +++ b/bus-mapping/src/circuit_input_builder.rs @@ -4,6 +4,7 @@ mod access;

Refactor `CircuitInputBuilder` to generate given number of `Chunk`s with fixed or dynamic params. Note that one instance of the circuit corresponds to one chunk instead of one block. Screen Shot 2023-12-08 at 11 37 30 PM ### Issue Link https://github.com/privacy-scaling-explorations/zkevm-circuits/issues/1696 ### Type of change - [ ] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [x] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] This change requires a documentation update ### Contents - Initialize the `CircuitInputBuilder` with either `FixedCParam` or just specify the total number of chunk and dynamically derive parameter after a dry run. - In `handle_tx` split the chunk whenever the local `rwc` exceeds the target amount, specifically by setting the `EndChunk` and proceed to the next `BeginChunk` if needed. - Commit the `ChunkCtx` for each chunk at the end, which tracks the global `Rw` range & local `rwc` later used in the State circuits. - After the block is handled, generate witness for a specific chunk with `builder.chunk_convert(idx)`, analogous to `builder.block_convert()`. - Config the circuit with both block and chunk, which leads to API changes in `SubCircuit` trait including `new_from_block(&block, &chunk)` and `min_num_rows_block(&block, &chunk)`. ### Workflow For `CircuitInputBuilder` chunk is needed to build **all** circuits: ``` let builder = BlockData::new_from_geth_data(geth_data.clone()) .new_circuit_input_builder() .handle_block(ð_block, &geth_traces) .expect("handle_block"); let block = block_convert(&builder); let chunk = chunk_convert(&builder, 0); let circuit = SuperCircuit::new_from_block(&block, &chunk); ``` For `CircuitTestBuilder` **modifier** is applied to both block and chunk, and you can run with fixed or dynamic params: ``` CircuitTestBuilder::new_from_test_ctx( TestContext::<2, 1>::simple_ctx_with_bytecode(bytecode).unwrap(), ) .modifier(Box::new(move |block, chunk| { // do something.. })) .run_dynamic_chunk(4, 2); ``` ``` CircuitTestBuilder::new_from_block(block) .params(FixedCParams { total_chunks: 2, max_rws: 60, ..Default::default() }) .run_chunk(1); ``` Default `run()` still works since it runs one chunk
