If it's known at `block` that `announce1` has been committed -//! and `announce2` has been committed after `announce1`, then -//! 1) `announce2` is strict successor of `announce1` -//! 2) `announce2.for_block` is a strict successor of `announce1.for_block` -//! 3) `announce2.committed_at_block` is a successor of `announce1.committed_at_block` -//! -//! ### STATEMENT3 (S3) -//! About local announces propagation. For correctness, strict rules must be followed to propagate announces. -//! If we have `block1` and `block2`, where `block2.parent == block1`, then -//! for any announce from `block2.announces` next statements must be true: -//! 1) `block1.announces.contains(announce.parent)` -//! 2) `announce.chain.contains(block2.last_committed_announce)` -//! 3) Any not-base announce1 from `announce.chain` is committed before `commitment_delay_limit`, except -//! maybe `commitment_delay_limit` newest announces in the `announce.chain`. -//! -//! ## Theorem and Consequences -//! -//! ### Definitions for Theorem 1 -//! - `block` - new received block from ethereum network. -//! - `lpb` - last propagated block, i.e. last predecessor of `block` for which announces were propagated. -//! - `chain` - ordered set of not propagated blocks till `block` (inclusive). -//! -//! ### THEOREM 1 (T1) -//! If `announce` is any announce committed in any block from `chain` -//! and `announce` is not yet included by this node, -//! then `common_predecessor_announce` must exists, such that -//! 1) included by this node -//! 2) strict predecessor of `announce` -//! 3) strict predecessor of at least one announce from `lpb.announces` -//! 4) `lpb.height - commitment_delay_limit <= common_predecessor_announce.for_block.height < lpb.height` -//! -//! ### T1 Consequences -//! If `announce` is committed in some block from `chain` and -//! this `announce` is not included yet, then -//! 1) (T1S1) `announce.for_block.height > lpb.height - commitment_delay_limit` -//! 2) (T1S2) if `announce1` is predecessor of any announce from `lpb.announces` -//! and `announce1.for_block.height <= lpb.height - commitment_delay_limit`, -//! then `announce1` is strict predecessor of `announce` and is predecessor of each -//! announce from `lpb.announces`. - -use crate::tx_validation::{TxValidity, TxValidityChecker};

Decides what an ethexe node should do as Ethereum blocks arrive: validate -//! announces produced by other nodes, produce announces of its own if it is -//! the producer for a block, coordinate threshold-signed batch commitments, -//! and submit those batches to the on-chain Router contract. -//! -//! Ethereum is the authoritative ledger — this crate does not invent its own -//! BFT protocol. It decides which announces to compute, collects enough -//! validator signatures on the resulting state, and posts the aggregated -//! commitment on-chain. Finality follows from the host chain. -//! -//! Two implementations of [`ConsensusService`] are provided: -//! -//! - [`ConnectService`] — a passive "connect-node" that tracks announces -//! from producers, asks `ethexe-compute` to execute them, and requests -//! missing announces from peers when needed. It knows the validator -//! set (so it can tell whose announce to accept for each block), but -//! it holds no signing key and does not submit anything on-chain. -//! - [`ValidatorService`] — an active validator. In addition to what -//! `ConnectService` does, it produces announces when it is the -//! producer for a block, collects validator signatures on batch -//! commitments, and submits the multi-signed batch to the Router -//! contract. -//! -//! Both share the same [`ConsensusService`] trait and the same -//! [`ConsensusEvent`] output stream, so `ethexe-service` can drive them -//! uniformly. +//! Once Malachite finalizes Sequencer Blocks (MBs) and `ethexe-compute` +//! executes them, the consensus crate is what posts the resulting state +//! transitions to the Ethereum Router contract. +//! +//! Per Ethereum block exactly one validator is elected as the *coordinator* +//! for that block (deterministically from the block timestamp). The +//! coordinator collects all MBs that finalized since the last on-chain +//! commitment, aggregates their outcomes into a [`BatchCommitment`], gossips +//! a validation request, and once it has enough threshold signatures pushes +//! the batch to the Router. Every other validator is a *participant*: it +//! waits for the coordinator's request, re-derives the same batch +//! independently, signs it if the digest matches, and replies. Off-cycle +//! both states sit in `WaitForEthBlock` waiting for the next Ethereum +//! chain head. +//! +//! Block production is *not* a concern of this crate any more — Malachite +//! drives MB ordering and `ethexe-compute` is responsible for execution. +//! Consensus only cares about turning finalized MBs into on-chain +//! commitments. //! //! ## Role in the stack and relation to other crates //! //! - `ethexe-observer` feeds Ethereum block data through //! [`ConsensusService::receive_new_chain_head`] and the follow-up //! [`ConsensusService::receive_synced_block`] notifications. -//! - `ethexe-compute` signals execution progress through -//! [`ConsensusService::receive_prepared_block`], -//! [`ConsensusService::receive_computed_announce`], and hands raw -//! promises back through -//! [`ConsensusService::receive_promise_for_signing`]. -//! - `ethexe-network` delivers producer announces, validation requests -//! and replies, fetched announces and network-forwarded injected -//! transactions. Outgoing network messages leave as -//! [`ConsensusEvent::PublishMessage`], [`ConsensusEvent::PublishPromise`] -//! and [`ConsensusEvent::RequestAnnounces`]. -//! - `ethexe-ethereum` is reached only from [`ValidatorService`], through -//! the [`BatchCommitter`] trait, to submit aggregated batch -//! commitments to the Router contract. [`ConnectService`] neither -//! signs nor posts anything on-chain. -//! - `ethexe-service` is the sole consumer: it routes every trait call -//! into the consensus service and routes every [`ConsensusEvent`] to -//! the right subsystem (compute, network, logs). +//! - `ethexe-compute` signals progress through +//! [`ConsensusService::receive_prepared_block`]. +//! - `ethexe-network` delivers validation requests/replies. +//! - `ethexe-ethereum` is reached through the [`BatchCommitter`] trait to +//! submit aggregated batch commitments to the Router contract. +//! - `ethexe-service` is the sole consumer. +//! +//! Connect (non-validator) nodes don't run this crate at all: their +//! `ConsensusService` is `None` in `ethexe-service` and they just observe +//! the chain plus execute MBs locally. //! //! ## Entry points //! //!

[`ConsensusEvent::PublishMessage`] with the validation request, -//! collects enough [`ConsensusService::receive_validation_reply`] calls -//! to satisfy the configured [`ValidatorConfig::signatures_threshold`], -//! and then submits the multi-signed batch through the injected -//! [`BatchCommitter`]. On success a [`ConsensusEvent::CommitmentSubmitted`] -//! is emitted. -//! - When acting as participant, the service validates the incoming -//! batch against its local state. On acceptance it publishes a signed -//! reply over [`ConsensusEvent::PublishMessage`]; on rejection it emits -//! a [`ConsensusEvent::Warning`] and sends nothing to the coordinator. -//! - Unexpected or malformed inputs produce [`ConsensusEvent::Warning`] -//! rather than aborting the service. -//! -//! ## Slot and era model -//! -//! The producer for a block is a deterministic function of the validator -//! set for the block's era and the block's timestamp. Era boundaries are -//! computed from the Ethereum block timestamp relative to the genesis -//! timestamp stored in the database config (see `ProtocolTimelines`). -//! -//! ## Injected transactions -//! -//! On a validator node, injected transactions are checked for standard -//! validity (not duplicated, not outdated, destination exists and is -//! initialized, etc.) and accepted ones are stored in a local pool. When -//! this validator is next the producer for a block, it drains pending -//! transactions from the pool into the announce it creates. -//! `ConnectService` ignores injected transactions entirely. -//! -//! ## When modifying this crate -//! -//! - Ethereum is the authoritative ledger. The crate -//! only decides which announces to execute and which batches to co-sign. -//! - A new Ethereum chain head always resets the validator to `Initial` -//! for that block. Do not introduce state carried across chain heads -//! beyond what is already kept in the database. -//! - `ConnectService` must never sign anything or submit anything -//! on-chain. It has no signer and no `BatchCommitter`; keep it that -//! way. -//! - Unexpected inputs (replies from non-validators, announces from -//! non-producers, transitions that do not match the current state) must -//! be surfaced as [`ConsensusEvent::Warning`], not as hard errors that -//! tear down the stream. -//! - The producer for a block must remain a pure function of on-chain -//! data and the block timestamp. Wall-clock time must not leak into -//! this decision (the only existing wall-clock knob is -//! [`ValidatorConfig::producer_delay`] and it only paces when the -//! producer acts, never who the producer is). -//! - A batch is submitted on-chain only after the number of collected -//! signatures reaches [`ValidatorConfig::signatures_threshold`]; this -//! is the sole trigger. +//! A new chain head always resets to `WaitForEthBlock`. use anyhow::Result; use ethexe_common::{ - Announce, Digest, HashOf, PromisePolicy, SimpleBlockData, - consensus::{BatchCommitmentValidationReply, VerifiedAnnounce, VerifiedValidationRequest}, - injected::{Promise, SignedInjectedTransaction, SignedPromise}, - network::{AnnouncesRequest, AnnouncesResponse, SignedValidatorMessage}, + Digest, SimpleBlockData, + consensus::{BatchCommitmentValidationReply, VerifiedValidationRequest}, + network::SignedValidatorMessage, }; use futures::{Stream, stream::FusedStream}; use gprimitives::H256; -pub use connect::ConnectService; pub use validator::{BatchCommitter, ValidatorConfig, ValidatorService}; -mod announces; -mod connect; -mod tx_validation; mod utils; mod validator; -#[cfg(test)] -mod mock; - pub trait ConsensusService: Stream> + FusedStream + Unpin + Send + 'static { - /// Returns the role info of the service + /// Returns the role info of the service. fn role(&self) -> String; - /// Process a new chain head + /// Process a new chain head. fn receive_new_chain_head(&mut self, block: SimpleBlockData) -> Result<()>; - /// Process a synced block info + /// Process a synced block notification. fn receive_synced_block(&mut self, block: H256) -> Result<()>; - /// Process a prepared block received + /// Process a prepared block notification. fn receive_prepared_block(&mut self, block: H256) -> Result<()>; - /// Process a computed block received - fn receive_computed_announce(&mut self, computed_announce: HashOf) -> Result<()>; - - /// Process a received producer announce - fn receive_announce(&mut self, announce: VerifiedAnnounce) -> Result<()>; - - /// Receives the raw promise for signing. - fn receive_promise_for_signing( - &mut self, - promise: Promise, - announce_hash: HashOf, - ) -> Result<()>; - - /// Process a received validation request + /// Process a received validation request. fn receive_validation_request(&mut self, request: VerifiedValidationRequest) -> Result<()>; - /// Process a received validation reply + /// Process a received validation reply. fn receive_validation_reply(&mut self, reply: BatchCommitmentValidationReply) -> Result<()>; - - /// Process a received announces data response - fn receive_announces_response(&mut self, response: AnnouncesResponse) -> Result<()>; - - /// Process a received injected transaction from network - fn receive_injected_transaction(&mut self, tx: SignedInjectedTransaction) -> Result<()>; } #[derive(Debug, Clone, PartialEq, Eq, derive_more::Display)] #[display("Commitment submitted, block_hash: {block_hash}, batch {batch_digest}, tx: {tx}")] pub struct CommitmentSubmitted { - /// Block hash for which the commitment was submitted - block_hash: H256, - /// Digest of the committed batch - batch_digest: Digest, - /// Hash of the submission transaction - tx: H256, + /// Block hash for which the commitment was submitted. + pub block_hash: H256, + /// Digest of the committed batch. + pub batch_digest: Digest, + /// Hash of the submission transaction. + pub tx: H256, } #[derive( Debug, Clone, PartialEq, Eq, derive_more::From, derive_more::IsVariant, derive_more::Unwrap, )] pub enum ConsensusEvent { - /// Announce from producer was accepted - AnnounceAccepted(HashOf), - /// Announce from producer was rejected - AnnounceRejected(HashOf), - /// Outer service have to compute announce - ComputeAnnounce(Announce, PromisePolicy), - /// Outer service have to publish signed message + /// Outer service has to publish signed message. #[from] PublishMessage(SignedValidatorMessage), - #[from] - PublishPromise(SignedPromise), - /// Outer service have to request announces - #[from] - RequestAnnounces(AnnouncesRequest), - /// Informational event: commitment was successfully submitted + /// Informational: a batch commitment was successfully submitted. #[from] CommitmentSubmitted(CommitmentSubmitted), - /// Informational event: during service processing, a warning situation was detected + /// Informational: a non-fatal anomaly was detected.
