Build on the Consensus Layer.

Solana consensus moved to sub-150ms Votor notarization. CELOR sits between real Solana sources and your application to handle multi-bank complexity and stream normalized protocol state.

Why This Changes Infrastructure

From “What happened?” to Multi-Bank Reality

In the Alpenglow era, applications cannot simply query standard RPC endpoints and assume single-block certainty.

BEFORE (Legacy TowerBFT RPC)

The developer asked RPC a single naive question:

“Did my transaction confirm on the cluster?”

• Single block linear assumption per slot
• Wait 12.8 seconds for 32 lockouts
• Blind to validator fork choice and optimistic handovers

AFTER (Alpenglow Multi-Bank World)

The developer must understand nuanced protocol state:

Which candidate bank?

Which parent block?

Did the parent switch?

Which certificate finalized it?

When was it produced?

When was it observed?

CELOR abstracts this entire complexity into a sub-microsecond, normalized event stream.
