Curio v1.27.3-rc3

v1 27 3-rc3_banner

✨ Overview

Curio v1.27.3-rc3 continues the path to a stable v1.27.3 release with bug fixes, dependency updates, and quality-of-life improvements. The headline fix addresses a timezone-related batch timeout bug that caused precommit and commit batches to fire late on non-UTC systems. Batch evaluation has been moved from opaque SQL into tested Go functions, with a new configurable MaxBatch setting for immediate batch firing when full.

Piece CID v1/v2 interoperability improves compatibility across client implementations, and a keccak dependency swap brings back ASM-optimized performance after upstream dropped it.

⭐ Highlights

⏱️ Batch Timeout Timezone Fix & Testable Evaluation

The precommit and commit batching triggers had a timezone mismatch where CURRENT_TIMESTAMP AT TIME ZONE 'UTC' stored into TIMESTAMPTZ columns was silently shifted by the session timezone. This caused batches to take timeout + abs(tz_offset) wall-clock time to fire instead of just timeout. All three SQL trigger functions now use NOW() directly, and the batch firing evaluation has been moved from PL/pgSQL into tested Go functions with comprehensive test coverage. A new MaxBatch config option fires batches immediately when they reach capacity.

🐛 Bug Fixes

  • fix: raw size only if unseal exists - prevents raw-size correction from running on sectors without unsealed data, avoiding unnecessary errors on storage paths (#1047)

  • fix: batch timeout timezone bug and move evaluation to testable Go - fixes timezone mismatch in precommit/commit batch triggers and moves evaluation into tested Go functions with configurable MaxBatch (#1044)

🔧 Improvements

  • allow piece CID v1 and v2 interoperability - handles both CIDv1 and CIDv2 piece CIDs, improving compatibility across different client implementations (#1048)

  • chore(deps): replace x/crypto with filecoin-project/go-keccak for optimised keccak - uses a maintained fork with ASM-optimized keccak256 after upstream x/crypto dropped assembly implementations in v0.44 (#1060)

  • better uniq - removes unnecessary allocations in the uniq utility for most common use cases (#1072)

What's Changed

  • fix raw size only if unseal exists by @LexLuthr in #1047
  • fix: batch timeout timezone bug and move evaluation to testable Go by @snadrus in #1044
  • chore(deps): replace x/crypto with filecoin-project/go-keccak for optimised keccak by @rvagg in #1060

Curio v1.27.3-rc2

This is release candidate 2 for v1.27.3, addressing issues reported by the community after rc1.
Thank you to everyone who tested rc1 and provided feedback - your reports directly drove these fixes. 🙏

🔧 Fixes since rc1

SQL / Pipeline Fixes

  • fix: FixRawSize CanAccept SQL array cast typo — fixed a SQL type error that could cause worker startup failures on storage paths with raw-size data (#1035)
  • fix: FixRawSize SQL column name, join, and filetype bugs — full audit of the FixRawSize migration path, correcting column references, JOIN logic, and filetype handling (#1037)

GPU / Build Fixes

  • fix(supraseal): add Turing (sm_75) back to CUDA architectures — restores support for Turing GPUs (RTX 2060/2070/2080, Tesla T4) in supraseal builds. Without this, Turing GPUs would segfault during supraseal operations (#1038)

Documentation

  • docs(administration): add node maintenance & cordoning guide — new operational guide for node maintenance workflows and cordon/drain procedures (#1030)

Dependencies

  • chore(deps): bump github.com/ethereum/go-ethereum from 1.16.8 to 1.17.0 (#1036)

⚠️ CUDA Compatibility Note

If you are running Turing GPUs (RTX 2080 Ti or older, sm_75), stay on CUDA 12.x. CUDA 13 does not support Turing architecture. The sm_75 fix in this release only helps if your CUDA toolkit version still supports your GPU.

GPU Architecture Examples Minimum CUDA Maximum CUDA
Turing (sm_75) RTX 2060/2070/2080, T4 12.0 12.x only
Ampere (sm_80/86) RTX 3090, A100 12.0 13.x
Ada Lovelace (sm_89) RTX 4090, L40 12.0 13.x
Hopper (sm_90) H100 12.0 13.x

Curio v1.27.3-rc1

curio_banner_27_3_rc1

✨ Overview

Curio v1.27.3-rc1 is a substantial update focused on performance, stability, and operational polish for our Curio Storage Providers. This release brings major improvements to the HarmonyTask scheduler - including batch task acceptance, smarter GPU distribution, and critical resource accounting fixes - making large-scale sealing operations significantly more efficient and reliable.

Operators benefit from a heavily upgraded WebUI with a complete sector page overhaul, new storage path management, and enhanced chain connectivity monitoring. The PDP subsystem gains a new sync task for on-chain state tracking, and Fast Snap encoding is now mainlined for faster SnapDeal processing. Across the board, this release hardens error handling, plugs goroutine and resource leaks, and delivers dozens of targeted bug fixes discovered through improved testing and real-world operator feedback.

⚠️ Build Dependency Changes (Linux)

Curio now compiles supraseal (for SnapDeals fast TreeR and batch sealing) by default on Linux.
This adds new build requirements:

Component Requirement
CUDA Toolkit 12.x or later (nvcc must be in PATH)
GCC 12 or 13 — must match your CUDA version
Python venv tooling + build tools (autoconf, automake, libtool, nasm, xxd)

Quick Dependency Install (Ubuntu/Debian)

sudo apt install -y mesa-opencl-icd ocl-icd-opencl-dev git jq pkg-config curl clang build-essential hwloc libhwloc-dev wget python3 python3-dev python3-pip python3-venv autoconf automake libtool libgmp-dev libconfig++-dev nasm xxd && sudo apt upgrade -y

Installing GCC 12 and 13 (Ubuntu/Debian)

Install versions:

For CUDA 12.5 and below


sudo apt install -y gcc-12 g++-12

or

For CUDA 12.6/13 and above


sudo apt install -y gcc-13 g++-13

Optional: Configure update-alternatives:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 120
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-13 130

sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-12 120
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-13 130

Select version:

sudo update-alternatives --config gcc
sudo update-alternatives --config g++

CUDA / GCC Compatibility

  • CUDA 12.0–12.5 → use gcc-12 / g++-12 only
  • CUDA 12.6+ → either GCC 12 or 13 works
  • CUDA 13+ → use gcc-13 / g++-13

Non-GPU / Non-CUDA Servers

If you don't have CUDA or want to skip supraseal:

# Option 1: Skip supraseal entirely
make build DISABLE_SUPRASEAL=1

# Option 2: Use OpenCL instead of CUDA (AMD GPUs or no NVIDIA GPU)
make build FFI_USE_OPENCL=1

The build will fail if nvcc is not found and no override flag is set.
This prevents accidental builds without proper GPU support.

⭐ Highlights

🚀 Batch Task Acceptance & Scheduler Improvements

HarmonyTask now accepts multiple tasks at once, dramatically improving throughput on machines with available capacity. Combined with reduced storage scheduling backoff times, smarter GPU round-robin distribution, and fixes to the shouldCommit flag, the scheduler is now faster, more responsive, and better at utilizing available hardware.

🖥️ WebUI Sector Page Overhaul & Storage Paths

The Sectors interface has been completely redesigned with richer deadline tooltips (including timing and PoSt submission warnings), proper Storage Path pages for managing and inspecting storage, and new RPC endpoints for storage path management. Chain Connectivity now includes Lotus network summary signals for better at-a-glance cluster health.

⚡ Fast Snap Encoding (Mainlined)

Fast Snap logic has been mainlined into Curio, enabling faster SnapDeal processing with optimized encoding paths. This is a significant performance win for operators doing snap upgrades at scale.

🛡️ Critical Resource Accounting Fixes

Several high-impact bugs were fixed in the task engine: a releaseStorage() function that never actually released anything (causing fake resource exhaustion), a goroutine leak in CommP calculation, a panic in the GPU device provisioner under overload, and corrected PoRep RAM allocation (50GB → 96GB) to prevent OOM crashes.

v1.25.1

Overview

We are excited to introduce Curio v1.25.1. This release brings the debut of the Proof Declaration Protocol (PDP), empowering storage providers with verifiable hot storage capabilities alongside various improvements and fixes.

You can read more about Curio in our documentation.

Compatibility

This release is compatible with Lotus versions v1.33.0. For the latest compatibility details, refer to the Curio version compatibility matrix.

⭐ Highlights

Proof Declaration Protocol (PDP)

Proof Declaration Protocol (Proof of Data Possession) is now supported in Curio, introducing a new on-demand proof mechanism for hot storage. With PDP, storage providers can cryptographically prove they hold an unsealed, immediately available copy of client data without the need to retrieve or unseal it. This new feature unlocks fast, verifiable retrieval use cases and complements Filecoin’s existing sealed storage (PoRep) by enabling a hot storage tier:

  • On-demand Proofs: Clients can challenge a storage provider at any time to quickly verify data availability via small random spot-checks (~160 bytes per challenge).

  • No Sealing/Unsealing Required: Data remains in raw form, eliminating sealing delays and making it suitable for real-time applications (e.g. web services, AI datasets).

  • Dynamic Datasets: PDP allows adding or removing data from proof sets, supporting mutable data collections that can be updated on the fly.

  • Easy Setup: Curio includes a new pdptool CLI for managing PDP proofs – providers can create ProofSets, upload files to be included in PDP, and declare proofs on-chain. No GPUs are required to participate in PDP, lowering the barrier to entry for hot storage providers.

This PDP integration is backed by smart contracts on the Filecoin network (FEVM), ensuring verifiable on-chain proof of data possession. Storage providers can now offer verifiable hot storage services with sub-second data access. 🚀

🛠️ Improvements

  • HTTP-Based MK12 Deals: Curio’s market now supports HTTP-based deal making for storage deals (Boost-style MK12 deals).

  • Optional CUDA Dependency: Installing and running Curio in a PDP-only mode no longer requires CUDA libraries. Users focusing solely on PDP operations can deploy Curio on machines without GPUs – make install now succeeds without CUDA, avoiding previous installation errors.

  • Missing Sector Alerts: Added proactive alerts for any missing sector files in storage. Curio will now flag missing or inaccessible sector data, helping operators quickly detect and resolve issues related to lost or moved sector files.

  • Message Fixer Tool: A new CLI tool is available to sync message status from Filfox. In case a message gets stuck or missed, operators can update the message with on-chain state fetched from the Filfox explorer to reconcile Curio’s view with the chain. Ex: curio toolbox fix-msg --all

  • Cheaper ProveCommit Aggregation: Curio’s prove commit message aggregation no longer relies on fee thresholds. Instead, batching is governed by time and size limits as per network parameters. This aligns with the latest network upgrade (e.g. FIP-0100) by removing the batch balancer.

Web UI Enhancements

  1. Pending Messages: The UI now displays pending chain messages (such as deal publish or proof submissions) so providers can track on-chain operations awaiting inclusion.

  2. PDP ProofSet View: Introduced PDP support in the UI, allowing providers to view and inspect PDP ProofSets and associated pieces through the browser. This ensures PDP data and status are visible and manageable via the dashboard.

🐞 Bug Fixes

  • UI Sector List: Fixed the Web UI’s sector list to properly show expired sectors. Previously expired/terminated sectors were hidden; the UI now correctly displays them, providing an accurate view of all sector states.

  • WindowPoSt Handling: Resolved several issues with Window PoSt tasks. Curio will now cancel a WindowPoSt task if the deadline has passed (preventing false failure logs), and the cancellation conditions have been corrected to avoid stuck WdPoSt processes. These fixes improve reliability and ensure no erroneous alerts for skipped or late proofs.

  • Deal Ingestion & Piece Locator: Fixed an issue with the piece locator’s database transaction during deal ingestion (FindURL). The offline deal data fetch now operates within the proper transaction scope, eliminating errors when adding piece URLs.

  • Build Process: The make batch build process has been fixed by separating out the sptool build. This resolves prior build failures when running batch build tasks and updates the documentation accordingly.

v1.25.0

Overview

We are excited to introduce Curio v1.25.0. This release enable the Filecoin Network upgrade to NV25 for Curio.

📖 You can read more about Curio in our documentation.

Compatibility

This release is compatible with Lotus versionv1.32.2. For the latest compatibility details, refer to the Curio version compatibility matrix.

⭐ Highlights

Balance Manager

The Balance Manager is a subsystem within Curio responsible for automatically managing balances for certain actors. Currently, it is used to top up deal collateral when the available balance falls below a defined threshold. In future iterations, the Balance Manager will be extended to handle control addresses and other balance-related operations.

CIDGravity Integration

Curio supports CIDGravity as external deal filter. CIDGravity is a powerful pricing and client management tool designed for Filecoin storage providers. It enables storage providers to efficiently filter storage and retrieval deals through a user-friendly interface. With CIDGravity, providers can set rules and policies for accepting or rejecting deals based on their business preferences, ensuring better control over their storage operations.

Human-friendly wallet names

Curio now supports assigning human-friendly names to wallets and PeerIDs through the new Wallets page in the UI. Once an entry is added, the UI will display the assigned name instead of the raw value. Names can be edited or deleted directly from the Wallets page.

🏗️ Improvements

  • BindSDRTreeToNode configuration option now ensures TreeD and TreeRC tasks run on the same node as the SDR task for improved data locality. Make sure TreeD and TreeRC tasks are enabled with sufficient resources before enabling this option.
  • New cli flag --db-cassandra-port allows users to choose a non default CQL API port for connecting to YugabyteDB CQL APIs.
  • PreCommit and Commit batch creation logic has been fully migrated to SQL to improve consistency. This eliminates race conditions that previously led to the same sector being assigned to multiple batches.
  • SupraSeal Batching: Fixed incorrect assumptions about hasher behaviour, resolving issues in single-hasher configurations.

🐛 Bug Fixes

  • Resolved the "0 rows found" error when deleting a deal pipeline from the UI.
  • Fixed an issue where sealed sectors were not reflected in the deal pipeline, causing deal processing to get stuck.
  • Fixed a bug where an unsealed copy was always retained, even when the deal explicitly specified not to keep it.
