Mar 1, 2026Month: 2026-03 | Filecoin-curio development focused on performance optimization, scalable data operations, testing maturity, and price/performance improvements in Snark proof workflows. Key business value includes faster in-memory deduplication, efficient batch processing for unsealing, and more reliable test coverage across databases, plus a more flexible proof-generation pathway. Key achievements: - Performance optimization: UniqNoAlloc deduplication for slices in Go (commit fbd1342f6a7617f8f958c4db0b04c986c837e639). Delivers non-allocating, faster duplicate removal for large slices, reducing GC pressure and memory usage in hot paths. - Batch unsealing of sectors using piece CIDs (commit f5e655595e700f03d9a8826cb3b2ed435950c423). Enables target unseal state setting for sectors based on piece CIDs with batch processing, supports reading multiple CIDs from stdin, plus docs and tests. Improves throughput and operational flexibility during sealing/unsealing workflows. - Testing infrastructure: PostgreSQL and ScyllaDB integration tests (commit aeeacfc60215617a31c37074d269a66bf106966d). Introduces integration testing capabilities with alternative databases, along with CI updates and dockerized DB containers to streamline local development and test organization. - Snark Market: consumer-based proof computation purchasing (commit 771f289e8bf2f9e3d629f783c1f464af36c6a487). Enables a consumer path for buying proof computation, reducing reliance on local GPU resources and increasing efficiency and flexibility in proof generation. Major bug fixes / stability adjustments: - Reverted multi-DB integration tests to YugabyteDB baseline (commit 2f3afdc3649714b11418a110ebd19901e8539364). Restores previous testing configuration to maintain CI stability while evaluating alternative DB backends. Overall impact and accomplishments: - Performance: Reduced memory allocations and faster deduplication in hot paths; potential GC and latency improvements for large-scale workloads. - Operational efficiency: Batch unsealing with piece CIDs improves throughput and scripting capabilities for large-scale data operations. - Testing maturity: Expanded integration test coverage with PostgreSQL/ScyllaDB and CI updates, bringing local development closer to production database configurations. - Cryptographic proof workflow: Consumer-based proof purchasing in Snark Market provides more flexible, cost-efficient proof generation and reduces GPU bottlenecks. Technologies/skills demonstrated: - Go performance engineering (non-allocating patterns) and slice deduplication. - Batch processing and stdin-driven CID handling for unsealing workflows. - Database testing: PostgreSQL, ScyllaDB, YugabyteDB, and containerized DB environments; CI workflow enhancements. - Snark Market integration: consumer-based proof computation flow.
