Expand description

The rw table shared between evm circuit and state circuit

Fields§

§q_step: Selector

Whether this row denotes a step. A read row is a step and a write row is not.

§is_last: Column<Advice>

Whether the row is the last read-write pair for a copy event.

§value: Column<Advice>

The value copied in this copy step.

§value_acc_rlc: Column<Advice>

Random linear combination accumulator value.

§is_pad: Column<Advice>

Whether the row is padding.

§is_code: Column<Advice>

In case of a bytecode tag, this denotes whether or not the copied byte is an opcode or push data byte.

§q_enable: Column<Fixed>

Whether the row is enabled or not.

§copy_table: CopyTable

The Copy Table contains the columns that are exposed via the lookup expressions

§addr_lt_addr_end: LtConfig<F, 8>

Lt chip to check: src_addr < src_addr_end. Since src_addr and src_addr_end are u64, 8 bytes are sufficient for the Lt chip.

§tx_table: TxTable

TxTable

§rw_table: RwTable

RwTable

§bytecode_table: BytecodeTable

BytecodeTable
