Build permissionless systems using Ghost Protocol on Umbraline.

The Ghostcoin Stack

Ghostcoin is the brand and native token.

Ghost Protocol is the commit-once, reveal-once cryptographic system.

Umbraline Testnet is the Layer 1 blockchain where Ghost Protocol contracts are deployed.

Ghost Protocol is not the chain.

Ghostcoin is not the protocol.

Umbraline is the execution layer.

What the Protocol Provides

Commit-once, reveal-once primitives

Cryptographic commitments and nullifiers

Zero-knowledge proof verification

Application callbacks for custom logic

Enforced terminal states

Developer Responsibilities

Secrets are generated and stored off-chain.

Loss of secrets means permanent loss.

Commitments cannot be reversed.

Reveals cannot be undone.

Correct off-chain computation is critical.

The protocol enforces rules; it does not protect against misuse.

Build for Correctness

Ghost Protocol prioritizes correctness over convenience.

Applications must be designed for one-way state.

There are no recovery paths by default.

The protocol assumes adversarial conditions.
