Use Cases
Protocol-enabled patterns built on commit-once, reveal-once primitives.
How to Read This Page
Ghost Protocol does not provide applications. It provides a primitive. The examples below illustrate classes of systems that become possible when data or value can leave on-chain state and be revealed exactly once or never.
Phantom Keys (Offline Bearer Instruments)
Assets or data can exist entirely off-chain as bearer-held secrets.
A commitment is recorded on-chain, then removed from live state. Control of the asset or data exists solely through possession of the Phantom Key. The blockchain has no visibility into who holds it or where it resides.
Why Ghost Protocol Matters: Only a commit-once, reveal-once system allows bearer-style ownership without accounts, balances, or recoverable state.
One-Time Access Tokens
Access can be granted exactly once, without accounts or revocation logic.
A commitment encodes access rights. Possession of the Phantom Key allows a single reveal that proves authorization. After reveal, the commitment enters a terminal state and can never be reused.
Why Ghost Protocol Matters: Traditional systems require servers, session state, or revocation lists. Ghost Protocol enforces one-time access cryptographically.
Private Credentials
Credentials can be proven once without creating a persistent identity.
A user commits to credential data and later reveals proof of possession exactly once. The protocol prevents reuse while avoiding identity correlation or credential registries.
Why Ghost Protocol Matters: The system guarantees non-replay without storing identities, accounts, or credential histories.
Sealed Data Release
Data can be committed now and released later under strict conditions.
A commitment seals data permanently. Reveal can be delayed, conditional, or never executed. If reveal occurs, it happens once and leaves no reusable state.
Why Ghost Protocol Matters: The protocol enforces finality and prevents partial or repeated disclosure.
Dead Man Switches
Data or value can be released only if the bearer fails to act.
A Phantom Key can be stored or escrowed off-chain. If predefined conditions are met, the key is revealed exactly once. If not, the commitment remains sealed forever.
Why Ghost Protocol Matters: This requires irreversible commitments and one-time reveal guarantees at the protocol level.
Privacy-Native Crypto Flows
Assets can leave the chain, move privately, and return once.
Funds are committed, removed from balances, and represented off-chain. When revealed, the protocol guarantees single-use redemption with no historical linkage.
Why Ghost Protocol Matters: This is not obfuscation. It is enforced absence of state.
Shared Properties
• No persistent accounts
• No balances to monitor
• No recoverability by design
• No replay or double-use
• Responsibility rests with the bearer
