What Exists Today
This page describes concrete facts about what has been built, what is running, and what remains to be done. No speculation, no roadmaps, no vague promises.
What Is Live
Umbraline Testnet
The blockchain is running:
- Validators are operational
- Blocks are being produced
- RPC endpoints are available
- The block explorer is functional
Anyone can connect a wallet and interact with the chain.
Core Contracts
The following contracts are deployed and operational:
| Contract | Function |
|---|---|
| GhostVault | Commit and reveal operations |
| GhostCommitmentTree | Commitment storage and Merkle roots |
| GhostNullifierRegistry | Double-spend prevention |
| GhostRedemptionVerifier | Zero-knowledge proof verification |
| GhostNativeHandler | Native GHOST token handling |
| GhostERC20Factory | Token deployment |
All contracts are verified on the block explorer.
Client Applications
Web Portal (portal.ghostcoin.com)
- Vanish (commit) operations
- Summon (reveal) operations
- Voucher management
- Token bridging interface
Mobile Applications
- iOS app (TestFlight)
- Android app (APK distribution)
- NFC card support for offline value
Developer Tools
Documentation (docs.umbraline.com)
- Full protocol specification
- Contract reference
- SDK documentation
- Tutorial walkthrough
Open Source
- All contracts are public
- Client libraries are available
- Circuit code is accessible
What Is Not Yet Live
Mainnet
The mainnet has not launched. Current status is testnet only. Tokens have no real value.
Independent Audits
Security audits are planned but not yet complete. The contracts have been internally reviewed but not independently audited.
Full Decentralization
Some infrastructure components are currently operated by the core team:
- Merkle tree relayer
- Bridge relayer
- RPC nodes
These will be decentralized before mainnet.
Multi-Chain Deployment
Ghost Protocol currently runs only on Umbraline. Deployment to other chains is planned but not implemented.
What Is Intentionally Unfinished
Some features are deliberately not implemented:
Recovery mechanisms. There is no way to recover lost secrets. This is by design.
Administrative controls. There are no admin keys that can freeze or modify commitments. This is by design.
KYC/AML integration. The protocol does not have built-in identity verification. This is by design.
These are not features waiting to be built. They are features that will never be built because they would compromise the protocol's guarantees.

Honest Assessment
Ghost Protocol is:
- Functional: The core protocol works as specified
- Early: This is testnet, not mainnet
- Unaudited: Independent security audits are pending
- Evolving: The implementation may change before mainnet
Ghost Protocol is not:
- Battle-tested: It has not survived sustained adversarial pressure
- Complete: Some planned features are not yet implemented
- Risk-free: Using it involves accepting the risks described in this whitepaper
This is an accurate description of current status. It will be updated as the project evolves.
