## What happened

Anza scheduled the Alpenglow migration on Solana mainnet-beta for Oct. 21 at about 14:50 UTC. Its documentation says Votor will replace TowerBFT.

## What changed

The migration would change the consensus and finality that the Solana versions of the assets Ketju tracks rely on. The documented handoff includes a short period with only votes before user transactions resume.

## What did not change

Ketju has not confirmed activation on mainnet. The notice changes no issuer entitlement, reserve, redemption contract or token administrator's authority. It does not show that holders cannot redeem or sell today.

## Confirmed

- Anza's notice of Oct. 13 gives the scheduled date and approximate time.
- The documented sequence activates SIMD-0384, reaches a boundary 5,000 slots later and requires a genesis certificate backed by 82% of stake.
- The documentation says votes move off-chain and user transactions resume after the consensus handoff.
- The documentation page has no publication date; Ketju dates it Oct. 14, the day Ketju read it.

## Still open

- It is not known whether activation will happen on schedule and complete.
- The actual pause in transactions, finality after the migration and compatibility of RPC services and indexers are not known.
- It is not known whether the issuer and transfer agent are ready for each affected Solana deployment.

## What it means for an advisor

- Ketju will review the operating and settlement assumptions in the three memos for these assets before the migration.
- After activation, Ketju will verify that transactions process and that issuer redemption works before it closes the review.
