CELOR/Protocol Transition Updates & Changelog
Alpenglow Transition Timeline
Chronological engineering record of the Solana consensus transition from legacy TowerBFT to Alpenglow Votor, along with CELOR low-level infrastructure releases.
PROTOCOL TRANSITIONOCTOBER 2026
LIVESolana Devnet Alpenglow Votor Activation Certified
Solana Devnet officially certified running Alpenglow Votor consensus with aggregate BLS12-381 certificate notarization.
- ✓Upgrade Genesis Slot recorded at #504,148,999.
- ✓Live observed consensus finality confirmed at ~231ms vs ~150ms protocol target.
- ✓Legacy TowerBFT 32-lockout finality superseded by direct validator BLS certificate notarization.
- ✓SVM transaction execution, program bytecodes, and fee structures confirmed 100% invariant/identical.
CELOR RELEASEOCTOBER 2026
COMPLETEDCELOR Phase 7 Conformance & Master Directives Certified
100% upstream protocol conformance achieved across Agave validator internals, BankGraph tracking, and QUIC execution routing.
- ✓Empirical N ≥ 10,000 latency benchmark suite validated with monotonic hardware timers (Instant::now).
- ✓Decoupled physical latency domains: isolated consensus finality from provider WebSocket transport lag.
- ✓Completed zero-allocation BankGraph tracking with instant UpdateParent parent invalidation.
- ✓Deployed live public dashboard to Cloudflare Pages with zero commercial vendor lock-in.
PROTOCOL TRANSITIONOCTOBER 2026
LIVESolana Testnet Alpenglow Staging Rollout
Solana Testnet upgraded to Alpenglow consensus at Genesis Slot #444,625,255 for validator release qualification.
- ✓Active validator operators testing fallback path notarization at 60% stake threshold.
- ✓Turbine block propagation evaluated under multi-candidate bank streaming topologies.
VALIDATOR MILESTONESEPTEMBER 2026
FEATURE-GATEDAgave 4.4 Multi-Candidate Bank & UpdateParent Hooks Merged
Anza Agave client branch integrates SIMD-0326 multi-bank generation and SIMD-0337 fast leader handover markers.
- ✓agave-validator client includes validator-local bank_id arena allocation.
- ✓Block footer serializer attaches BLS12-381 aggregate certificates to sealed block trailers.
CELOR RELEASEAUGUST 2026
COMPLETEDCELOR Phase 6 Full-Fidelity Geyser Telemetry Plugin Released
Released the open-source Celor Geyser Plugin enabling Level 4 validator-side telemetry on local nodes.
- ✓Ingests direct memory-mapped candidate bank lifecycle events via Unix Domain Sockets.
- ✓Captures pre-execution deshred streams before transaction processing begins.
- ✓High-precision nanosecond producer timestamps extracted from block footers.
