RustChain Offers Bug Bounty for Critical UTXO Migration Code Review

RustChain is offering a bounty for red team testing of its newly implemented UTXO (Unspent Transaction Output) model, a fundamental architectural shift from its previous account-based system. The core code for 'Phase 1+2' has just been committed, and the project is soliciting adversarial review before enabling a dual-write feature on production, explicitly inviting testers to 'Break it, get paid.' This move signals a critical, high-stakes transition in the blockchain's core logic.

The bounty focuses on several key files in the `node/` directory, including the ~708-line `utxo_db.py` which forms the core database layer for UTXOs, transactions, and coin selection. Reviewers are directed to look for critical vulnerabilities, with the top reward of 200 RTC reserved for flaws like double-spend conditions, consensus failures, or database corruption that could lead to a total network halt. A secondary tier offers 50 RTC for logic errors affecting transaction validity or coin selection.

This proactive bounty hunt underscores the inherent risks in a live blockchain migrating its fundamental data model. The code is currently behind a `UTXO_DUAL_WRITE` feature flag, indicating a controlled rollout is planned. However, the call for red team scrutiny before production activation highlights the potential for severe financial and operational disruption if critical bugs slip through. The project's security posture now hinges on the effectiveness of this crowdsourced audit.
