GHOST: private-holdings proofs on Solana

Editorial interest 78/100 Selection signal · not a rating of the site

GHOST describes a Solana protocol for proving a wallet meets a token-holding threshold without revealing its address or exact balance.

Landing page captured for the 2026-10-15 issue.

For: Solana apps gating access by token holdings
Worth noticing: Proofs use a signed snapshot at a finalized slot, so they establish historical—not live—balances.

Field notes

The documented flow starts with a browser-generated secret and a wallet signature, then relies on an attester to sign a Merkle root built from SPL balances at a finalized slot. Verifiers can set an acceptable snapshot age and use fresh challenges plus app-scoped nullifiers. The page says the attester could include false balances, while also noting that small anonymity sets and network logs can still expose activity.
