From a08e3c46e98dfa9c76549e83a12fe45695ae17c2 Mon Sep 17 00:00:00 2001 From: BlobMaster41 <96896824+BlobMaster41@users.noreply.github.com> Date: Thu, 12 Mar 2026 05:17:52 -0400 Subject: [PATCH 1/9] Add WITNESS worker thread and pipeline Introduce a dedicated WITNESS thread and supporting pipeline to offload block-witness generation and peer witness handling. Changes include: - New ThreadTypes.WITNESS and MessageType entries for witness-related messages. - New WitnessThread and WitnessThreadManager to receive forwarded block events and peer witness data, buffer early peer messages, and coordinate witness processing. - WitnessSerializer utilities to reconstruct Long instances lost by structured-clone when crossing worker boundaries (reconstructBlockWitness / reconstructSyncResponse). - BlockWitnessManager: added selfWitness queue, concurrent self-proof generation (draining logic, MAX_CONCURRENT_SELF_PROOFS), and queueSelfWitness API to decouple/async self-witness creation. - P2PManager: methods to queue self proofs, update consensus height, broadcast/request witnesses, and forward incoming peer witness messages/responses to the WITNESS thread. - PoC & PoCThread: forward BLOCK_PROCESSED events to the WITNESS thread, add APIs to request/broadcast witnesses, and reconstruct witnesses on receipt from worker threads. - Threading/Services updates: wire up the WITNESS thread in Core, PoCThreadManager, BitcoinRPCThreadManager, ServicesConfigurations and WorkerConfigurations so the thread is created and linked. - Tests: add unit tests for WitnessSerializer and WitnessThread behavior. - Minor config change: use btc.sample.conf as configPath in Config.ts. Rationale: separate heavy/IO-bound witness proof generation into its own worker to avoid blocking P2P/indexer threads, handle structured-clone degradation of Longs across worker boundaries, and allow controlled concurrency for self-generated proof work. --- src/src/Core.ts | 1 + .../rpc/BitcoinRPCThreadManager.ts | 1 + src/src/config/Config.ts | 2 +- src/src/poc/PoC.ts | 20 +- src/src/poc/PoCThread.ts | 28 + src/src/poc/PoCThreadManager.ts | 1 + src/src/poc/networking/P2PManager.ts | 54 +- .../poc/networking/p2p/BlockWitnessManager.ts | 116 +- src/src/poc/witness/WitnessSerializer.ts | 70 + src/src/poc/witness/WitnessThread.ts | 178 +++ src/src/poc/witness/WitnessThreadManager.ts | 84 ++ src/src/services/ServicesConfigurations.ts | 14 + src/src/threading/enum/MessageType.ts | 7 + src/src/threading/thread/enums/ThreadTypes.ts | 1 + tests/witness/WitnessSerializer.test.ts | 425 ++++++ tests/witness/WitnessThread.test.ts | 1155 +++++++++++++++++ tests/witness/setup.ts | 5 + 17 files changed, 2151 insertions(+), 11 deletions(-) create mode 100644 src/src/poc/witness/WitnessSerializer.ts create mode 100644 src/src/poc/witness/WitnessThread.ts create mode 100644 src/src/poc/witness/WitnessThreadManager.ts create mode 100644 tests/witness/WitnessSerializer.test.ts create mode 100644 tests/witness/WitnessThread.test.ts create mode 100644 tests/witness/setup.ts diff --git a/src/src/Core.ts b/src/src/Core.ts index ac89efe35..d017dd61c 100644 --- a/src/src/Core.ts +++ b/src/src/Core.ts @@ -68,6 +68,7 @@ export class Core extends Logger { await this.createThread(ThreadTypes.MEMPOOL_MANAGER);

PoC.onBlockProcessed is serialized via a promise lock, broadcasts WITNESS_HEIGHT_UPDATE to all witnesses, awaits it, then sends WITNESS_BLOCK_PROCESSED to one witness. WitnessThread now handles WITNESS_HEIGHT_UPDATE to set currentBlock and flush buffered peer messages; WITNESS_BLOCK_PROCESSED no longer sets height or receives an onHeightSet callback. Added handling for WITNESS messages in BitcoinRPCThread and a small comment in WitnessThreadManager. Updated tests to reflect the new message flow and behavior. --- .../rpc/thread/BitcoinRPCThread.ts | 3 + src/src/poc/PoC.ts | 21 ++- src/src/poc/witness/WitnessThread.ts | 43 +++--- src/src/threading/enum/MessageType.ts | 5 +- tests/witness/WitnessThread.test.ts | 134 +++++++++--------- 5 files changed, 113 insertions(+), 93 deletions(-) diff --git a/src/src/blockchain-indexer/rpc/thread/BitcoinRPCThread.ts b/src/src/blockchain-indexer/rpc/thread/BitcoinRPCThread.ts index fbd7a586d..9416ad6ec 100644 --- a/src/src/blockchain-indexer/rpc/thread/BitcoinRPCThread.ts +++ b/src/src/blockchain-indexer/rpc/thread/BitcoinRPCThread.ts @@ -92,6 +92,9 @@ export class BitcoinRPCThread extends Thread { case ThreadTypes.MEMPOOL: { return await this.processAPIMessage(m as RPCMessage); } + case ThreadTypes.WITNESS: { + return await this.processAPIMessage(m as RPCMessage); + } default: this.log(`Unknown thread message received. {Type: ${m.type}}`); break; diff --git a/src/src/poc/PoC.ts b/src/src/poc/PoC.ts index 6bfeaa762..5898a2310 100644 --- a/src/src/poc/PoC.ts +++ b/src/src/poc/PoC.ts @@ -16,6 +16,9 @@ export class PoC extends Logger { private readonly p2p: P2PManager; + /** Serializes onBlockProcessed calls so each completes before the next starts. */ + private blockProcessedLock: Promise = Promise.resolve(); + constructor(private readonly config: BtcIndexerConfig) { super(); @@ -49,7 +52,7 @@ export class PoC extends Logger { ): Promise { switch (m.type) { case MessageType.BLOCK_PROCESSED: { - return this.onBlockProcessed(m as BlockProcessedMessage); + return await this.onBlockProcessed(m as BlockProcessedMessage); } case MessageType.RPC_METHOD: { return await this.handleRPCMessage(m as RPCMessage); @@ -103,14 +106,24 @@ export class PoC extends Logger { return this.sendMessageToAllThreads(threadType, m); } - private onBlockProcessed(m: BlockProcessedMessage): ThreadData { - // Forward to dedicated WITNESS thread for heavy proof generation + private async onBlockProcessed(m: BlockProcessedMessage): Promise { + // Wait for previous block to finish so height + proof are always in order. + await this.blockProcessedLock; + + // Broadcast height to ALL witness instances + this.blockProcessedLock = this.sendMessageToAllThreads(ThreadTypes.WITNESS, { + type: MessageType.WITNESS_HEIGHT_UPDATE, + data: { blockNumber: m.data.blockNumber }, + }); + await this.blockProcessedLock; + + // Round-robin proof generation to ONE witness instance void this.sendMessageToThread(ThreadTypes.WITNESS, { type: MessageType.WITNESS_BLOCK_PROCESSED, data: m.data, }); - // Lightweight: update consensus height on this thread + // Update consensus height on this thread this.p2p.updateConsensusHeight(m.data.blockNumber); return {}; diff --git a/src/src/poc/witness/WitnessThread.ts b/src/src/poc/witness/WitnessThread.ts index 82503daef..767cd859d 100644 --- a/src/src/poc/witness/WitnessThread.ts +++ b/src/src/poc/witness/WitnessThread.ts @@ -90,27 +90,32 @@ export class WitnessThread extends Thread { } switch (m.type) { + case MessageType.WITNESS_HEIGHT_UPDATE: { + // Broadcast to ALL instances: update currentBlock so peer witnesses + // for recent blocks are accepted (not rejected as "too old"). + const { blockNumber } = m.data as { blockNumber: bigint }; + void this.blockWitnessManager.setCurrentBlock(blockNumber, true); + + if (!this.currentBlockSet) { + this.currentBlockSet = true; + // Height is now set — replay any buffered peer witnesses + this.flushPendingPeerMessages(); + } + + return {}; + } case MessageType.WITNESS_BLOCK_PROCESSED: { + // Round-robin to ONE instance: generate proof for this block. + // Height is already set by WITNESS_HEIGHT_UPDATE (broadcast). const data = m.data as BlockProcessedData; - const isFirst = !this.currentBlockSet; - if (isFirst) this.currentBlockSet = true; - - this.blockWitnessManager.queueSelfWitness( - data, - () => { - // After witness generated, tell P2P to request from peers - void this.sendMessageToThread(ThreadTypes.P2P, { - type: MessageType.WITNESS_REQUEST_PEERS, - data: { blockNumber: data.blockNumber }, - }); - }, - isFirst - ?

Ensure Long values are parsed as unsigned by passing the unsigned flag to Long.fromString/fromNumber in WitnessSerializer. Add error handling for the async onBlockWitnessResponse call in WitnessThread to log rejections instead of leaving unhandled promise rejections. Update tests to await async onBlockProcessed behavior and add tests covering serialized height broadcasts and burst handling to ensure ordering and no dropped blocks. --- .../poc/networking/p2p/BlockWitnessManager.ts | 16 +++-- src/src/poc/witness/WitnessSerializer.ts | 6 +- src/src/poc/witness/WitnessThread.ts | 4 +- tests/witness/WitnessThread.test.ts | 67 +++++++++++++++++-- 4 files changed, 77 insertions(+), 16 deletions(-) diff --git a/src/src/poc/networking/p2p/BlockWitnessManager.ts b/src/src/poc/networking/p2p/BlockWitnessManager.ts index a4573f755..92de6552f 100644 --- a/src/src/poc/networking/p2p/BlockWitnessManager.ts +++ b/src/src/poc/networking/p2p/BlockWitnessManager.ts @@ -78,6 +78,9 @@ export class BlockWitnessManager extends Logger { private selfQueueDraining: boolean = false;
