PROFILE
Matteo Almanza
Matteo Jug developed and maintained core infrastructure for the stacks-network/sbtc repository, focusing on reliability, security, and operational efficiency in Bitcoin and Stacks blockchain integration. Over ten months, Matteo delivered features such as deposit workflow correctness, DKG lifecycle management, and robust withdrawal tracking, using Rust and SQL to implement resilient backend logic and database migrations. He improved test automation and CI/CD pipelines, stabilized integration tests, and enhanced observability through logging and Docker-based deployments. Matteo’s work addressed edge cases like blockchain forks and nonce conflicts, demonstrating depth in distributed systems and cryptography while reducing technical debt and deployment risk.

Jun 1, 2025June 2025 monthly summary for stacks-network/sbtc: Delivered reliability and stability improvements across signing, distributed key generation (DKG), nonce handling, and documentation, focusing on reducing duplicate work, preserving DKG progress, avoiding nonce-related transaction failures, and improving testnet accessibility. Key outcomes include implementing an LRU cache to prevent signing the same Stacks transaction within a tenure, gating new DKG rounds behind verification of existing shares, correcting nonce handling to stop decrementing on ConflictingNonceInMempool errors, and updating the regtest chainstate documentation link.

Apr 1, 2025Monthly summary for 2025-04 focusing on reliability and infrastructure improvements in stacks-network/sbtc. Key deliverables include: (1) robust handling of coinbase transactions for sBTC with graceful ignore, logging, and a dedicated error variant; integration tests verify correct behavior; avoids disruption of sBTC deposits. (2) Infrastructure compatibility update: bumped stacks-blockchain-api image from 8.6.0 to 8.9.0 in Docker Compose to maintain Leather compatibility and removed obsolete Git tag environment variable. These changes reduce deposit failures and prep the stack for Leather upgrades, with clear observability through logs and tests.
