Weekly Development Snapshot Status September 18th: QRL Release Verifier audit complete September 11th: Ledger app audit and remediation complete August 4th: Audit results published for go-qrllib April 3rd: Audit complete of 2 cryptographic libraries March 31st: QRL 2.0 Testnet V2 released Audits & Remediation: 60% QRL 2.0 Testnet V3 checklist from that update:
Config parameters [done] Upstream bug fixes Testnet V2 scoped audits QRL 2.0 qrysm
Improved fork-choice and block-import recovery, preserving votes, finalization and execution validation across partial failures, cancellations and reorganizations Fixed handling of skipped-slot checkpoints, duplicate blocks and state recovery when blocks disappear during reads Improved state snapshot isolation and cache consistency, and released detached validator references to avoid retaining unused memory Hardened deposit processing and execution RPC handling against malformed responses, failed batches and timeouts Corrected SSZ encoding bounds and Merkle proof construction, and preserved signatures, deposit commitments and proposer slashings during copying and conversion Fixed voluntary exits to load custom chain configuration, so exits use the correct network’s signing parameters Added regression coverage for the fixes qrl-tests
Added automated consensus and staking test suite, covering deposits, validator activation, attestations, voluntary exits and withdrawals on a live test network Added the suite to nightly testing, with deposit waits derived from the live chain configuration and exits signed through the validator keymanager API go-qrllib
Added an additional Falcon-1024 tests, covering randomized encoding and FFT operations, sampling, key derivation and signing Included checks for architecture-sensitive key derivation; the upstream Falcon-1024 integration remains in review Updated the upstream Codecov CI action to v7.1.1 rust-qrllib
Added ML-DSA tests confirming that signing fails after secret-key zeroization, repeated zeroization is safe, and the public key can still verify earlier signatures Refreshed Rust crates, demo dependencies and CI action pins qrypto.js
Updated development dependencies and CI action pins, including Mocha 12 and refreshed linting, formatting, build and browser-test tooling QRL 1.x QRL
Corrected multisig test seed descriptors on the same branch qryptonight / qrandomx
Switched Linux builds to portable CPU targets, improving compatibility across x86-64 and ARM64 hardware Preserved optimized Argon2 runtime selection in qrandomx while using the portable build baseline Fixed source-distribution builds and version metadata; published pyqryptonight 0.99.13 and pyqrandomx 0.3.4 qrl-docker / qrl-docker-ci
Documented the portable CPU baseline and how operators can verify their images Removed temporary compiler-wrapper workarounds from the Bionic and Focal images after the mining-library fixes became available Added Clang 18 to the Noble CI image for ThreadSanitizer testing qrl-v1-docker-cluster
Added a tool for running disposable QRL 1.x test networks across multiple Docker images Checks node health, mining, agreement on block hashes, wallet persistence and CPU instruction compatibility, then saves a report and logs
