Why a Dedicated Chain Matters
Ghost Protocol requires specific properties from its execution environment. A dedicated chain provides these properties without compromise.
Gas Cost Optimization
Privacy operations are expensive:
Zero-knowledge proof verification costs approximately 300,000 gas per transaction.
Merkle tree operations require multiple hash computations.
On-chain state updates must record commitments and nullifiers.
On congested chains like Ethereum mainnet, these operations can cost tens or hundreds of dollars. On Umbraline, they cost a fraction of a cent.
This is not just a matter of cost. High gas prices exclude users. A privacy system that only wealthy users can afford is not useful privacy infrastructure.
Predictable Capacity
Privacy operations should not compete with unrelated applications for blockspace.
When NFT mints spike gas prices, privacy transactions should not be priced out. When DeFi liquidations fill blocks, privacy reveals should not be delayed.
Umbraline provides dedicated capacity for privacy operations. Users can rely on consistent availability and pricing.
Chain-Level Privacy
Some privacy properties require chain-level support:
Native token privacy. GHOST is the native gas token on Umbraline. Privacy operations involving GHOST do not require wrapping or approvals.
No default logging. Umbraline does not expose transaction data in ways that could be correlated.
Privacy-aware indexing. Chain explorers and indexers are configured with privacy in mind.
These properties are difficult to achieve on chains not designed for privacy.
Governance Alignment
Chains are governed. Governance decisions affect all applications on the chain.
On general-purpose chains, governance must balance many stakeholders with different priorities. Privacy concerns may be overridden by other interests.
Umbraline's governance prioritizes privacy. Decisions are made with Ghost Protocol's needs as the primary consideration.
Separation of Concerns
Running Ghost Protocol on its own chain provides clean separation:
Protocol changes can be made without affecting unrelated applications.
Security incidents on other chains do not directly impact Umbraline.
Upgrades can be scheduled around Ghost Protocol's needs.
State growth is limited to privacy-relevant data.
This separation makes the system more maintainable and easier to reason about.
The Bridge Connection
Umbraline does not exist in isolation. Bridges connect it to other networks:
Assets can move in. Users can bridge tokens from Ethereum, Avalanche C-Chain, and other networks.
Value can move out. Users can exit Umbraline by bridging back to their origin chain.
Cross-chain composability. Applications on other chains can interact with Ghost Protocol through bridge messaging.
The dedicated chain is not a walled garden. It is a specialized environment connected to the broader ecosystem.
