Solana's consensus layerhas fundamentally changed.

VOTOR BLS CERTIFICATES

Alpenglow replaces TowerBFT with direct validator BLS certificate notarization, while transaction execution remains identical. CELOR sits between real Solana sources and developers to normalize multi-candidate banks, track parent changes, and expose the new consensus state.

Alpenglow Bank Graph (SIMD-0326 / SIMD-0337)

Candidate banks.
Slots are no longer single blocks.

Under fast leader handover, leaders initiate blocks optimistically. Multiple banks compete per slot until one is notarized by consensus.
SIMD-0337 UpdateParent live stream monitor active
Consensus Reality in Normal English

Multiple versions of a slot can exist simultaneously.

Old idea: “One slot = one block.”
New Alpenglow reality: “More than one version of a slot can exist while validators decide which one continues.”
VERSION A (Candidate)DROPPED

Built optimistically on an unfinalized predecessor. When validators switch parents via UpdateParent, Version A is abandoned.

State: ABANDONED
Uncommitted txs: State purged & rolled back
VALIDATOR FORK CHOICEFast Leader Handover (SIMD-0337)
VERSION B (Canonical)CONTINUES

Gathers 80% stake notarization certificate. Promoted to canonical head of the chain.

PROTOCOL ARCHITECTURE • SIMD-0326

Consensus changed.
Execution did not.

Solana itself emphasizes: SVM transaction execution (programs, accounts, fees) remains unchanged. What changes is the consensus mechanism itself: direct validator voting and aggregate BLS certificates replace 32 progressive on-chain lockouts.

1

Execution Invariance vs Consensus Evolution
UNCHANGED (Execution Layer)
  • SVM Runtime: Same BPF/eBPF bytecode execution
  • Programs & Contracts: Zero code changes required for dApps
  • Transactions & Fees: Standard signature format & priority fees
CHANGED (Consensus & Ingestion Layer)
  • Consensus: TowerBFT replaced by Votor notarization certificates
  • Multi-Bank Behavior: Multiple candidate versions exist per slot
  • Infrastructure: Low-level indexers must understand bank_id & UpdateParent

Forensic Analysis

Transaction autopsy.

Inspect the exact candidate bank, parent lineage, and finality path of any transaction. Verify if an execution survived a fast leader parent switch.

Developer Primitives

Open infrastructure.
Zero vendor lock-in.

CELOR unifies fragmented RPC WebSockets, Yellowstone gRPC, and validator local states into a clean, normalized stream.

Rust Core Source of Truth

All protocol state, bank graphs, and finality tracked strictly in high-performance Rust.

Zero Browser RPC Networking

Frontend consumes normalized local stream. Zero direct browser-to-Solana RPC latency.

Monotonic Sequence Numbering

Every event carries a sequence number for gap detection and instant ring-buffer replay.

$0-First Devnet & Local Fixtures

Runs entirely on open Devnet/Testnet or deterministic local Geyser specification fixtures.
