What happened
The new consensus protocol retires TowerBFT, which had run Solana since its 2020 launch, after a handoff on the live network.
Reported details
- Alpenglow will replace the voting system Solana has used since 2020, targeting roughly 150-millisecond finality after months of testing that included a failed migration and rollback.
Why this matters
This reads as a change in infrastructure rather than a move in price, and that distinction decides what is worth verifying: whether the underlying record moved, or only the interface around it. If a ledger, custodian or settlement term is unchanged, then anything built on top of it behaves the same too, however the announcement is framed. Subject of the report: Solana Alpenglow Goes Live.
Evidence boundary
On Solana Alpenglow Goes Live, the scope is limited to what the linked 2 reports state, and where they diverge both positions are recorded without either being picked in advance; the headline figure is what to check first.
What to verify
If Solana Alpenglow Goes Live points at a contract or a chain, verify the deployed address and version there. If it describes an internal or corporate change with no on-chain component, the chain is the wrong place to look.
