Aere Network public source. Everything here can be checked against the live chain (chain id 2800, https://rpc.aere.network). Scope note, stated up front rather than buried: consensus on chain 2800 is classical secp256k1 ECDSA QBFT. The post-quantum work in this repository is at the signature, precompile, account and transport layers. Nothing here makes the consensus post-quantum, and no document in it should be read as claiming so.

/**
|
|
* @title AereEVMValidity - on-chain anchor for REAL FULL-EVM validity proofs of
|
|
* live chain-2800 blocks.
|
|
*
|
|
* @notice Verifies SP1 zkVM Groth16 proofs that a REAL AERE mainnet (chain 2800,
|
|
* QBFT / Besu) block was re-executed with revm INSIDE the zkVM and that
|
|
* the recomputed post-state root equals the `header.stateRoot` carried in
|
|
* the proof's public values. The guest (bin/aere-client) runs the
|
|
* SP1-patched reth 1.9.3 / revm stack over the block's transactions against
|
|
* the parent-block pre-state (account + storage MPT proofs gathered by the
|
|
* host from `eth_getProof`), re-roots the sparse trie, and only produces a
|
|
* valid proof when computed stateRoot == header.stateRoot.
|
|
*
|
|
* BINDING CAVEAT (READ THIS): this V1 anchor attests a SELF-CONSISTENT
|
|
* execution, NOT that the recorded block is the CANONICAL chain-2800 block
|
|
* at that height. The public values carry no blockHash/parentHash and this
|
|
* contract performs no blockhash() check, so a genuine SP1 proof of a
|
|
* FABRICATED execution can be recorded here, and first-write-wins dedup lets
|
|
* a slot be squatted. Do NOT treat a V1 record as canonical. Canonical
|
|
* binding (committed blockHash + on-chain blockhash()/EIP-2935 check + batch
|
|
* continuity) lands in AereEVMValidityV2 / AereEVMValidityBatchV2.
|
|
*
|
|
* Unlike AereRollupValidity (which proves AERE's BOUNDED toy-VM executor:
|
|
* Transfer/Sweep/Increment/AmmSwap), this contract anchors proofs of
|
|
* ARBITRARY EVM bytecode execution: full opcode set, call frames,
|
|
* SLOAD/SSTORE, LOG, EIP-1559 base-fee burn + priority-to-coinbase, and
|
|
* the Cancun/Prague/Osaka system calls, all of which affect the proven
|
|
* state root.
|
|
*
|
|
* PROGRAM BINDING: PROGRAM_VKEY is the SP1 verification key of the exact
|
|
* guest ELF that performs revm-in-zkVM execution + witness re-root.
|
|
* Binding the vkey binds the exact prover program.
|
|
*
|
|
* PUBLIC-VALUES CONVENTION (exactly 224 bytes = 7 x 32):
|
|
* abi.encode(
|
|
* uint256 chainId, // must equal block.chainid (2800)
|
|
* uint256 blockNumber, // the proven chain-2800 block height
|
|
* bytes32 prevStateRoot, // parent block state root (pre-state anchor,
|
|
* // NOT cross-checked on-chain in V1)
|
|
* bytes32 postStateRoot, // self-consistent post-execution state root
|
|
* bytes32 txRoot, // header.transactionsRoot (binds the txs)
|
|
* uint256 gasUsed, // total gas used by the block
|
|
* uint256 numTxns // number of transactions executed
|
|
* )
|
|
*
|
|
* IMMUTABILITY / TRUST: SP1_VERIFIER and PROGRAM_VKEY are fixed at deploy.
|
|
* There is NO owner and NO admin: recording is permissionless. Soundness
|
|
* rests entirely on the SP1 Groth16 proof: a record can only be written
|
|
* for a (blockNumber, prevStateRoot, postStateRoot) triple that the zk
|
|
* proof establishes for PROGRAM_VKEY.
|
|
*
|
|
* ===========================================================================
|
|
* HONEST SCOPE - READ THIS.
|
|
* ===========================================================================
|
|
* This proves REAL EVM execution of a SMALL live chain-2800 block (a handful
|
|
* of transactions). It is a legitimate real-EVM validity PROOF-OF-APPROACH.
|
|
* It is NOT yet a full-throughput production rollup: it does not prove a large
|
|
* batch, and it records isolated proven blocks rather than a continuous
|
|
* sequencer chain. No code, UI or claim built on it should imply otherwise.
|
|
* ===========================================================================
