Multi-Chain Considerations
Multi-Chain Considerations describe how ZKFund preserves privacy and correctness when operating across multiple blockchains.
ZKFund is not designed for a single execution environment. It assumes that capital, liquidity, and users will span multiple chains—and that no single chain should be able to observe the full picture.
The Risk of Multi-Chain Visibility
Operating across multiple chains usually increases, not reduces, exposure.
When execution spans chains:
actions can be correlated by timing
bridges leak intent
settlement patterns become observable
one chain can reveal context about another
If not designed carefully, multi-chain operation becomes a privacy liability.
Chain-Agnostic Privacy Model
ZKFund’s privacy model does not rely on:
a specific VM
a specific consensus model
synchronous execution
Each chain is treated as an isolated verification environment.
A chain only learns:
that a proof is valid
that a settlement occurred
that rules were followed
It never learns why, how, or in relation to other chains.
Fragmented Visibility by Design
In a multi-chain setup:
no single chain sees full treasury state
no chain sees full execution history
no chain sees full governance context
Each chain observes only its local proof receipts.
Even if data from multiple chains is aggregated, it cannot be stitched into a coherent global narrative.
Cross-Chain Settlement Without Correlation
When assets move across chains:
settlement is broken into independent steps
each step produces its own proof
proofs are not linkable across chains
There is no global transaction identifier, no shared address, and no timing guarantee that allows correlation.
Governance Remains Single-Source
While execution is multi-chain, governance is not fragmented.
ZK DAO remains:
the single source of authority
chain-agnostic
proof-enforced
All chains verify execution against the same governance rules, without sharing execution context.
Avoiding Bridge-Centric Leakage
Traditional bridges often become privacy choke points.
ZKFund avoids this by:
abstracting bridges behind ZK Pool
enforcing constraints locally
proving correctness without exposing routing
The bridge is treated as an implementation detail, not a visible actor.
Failure Isolation
Failures on one chain:
do not leak intent to others
do not expose partial state
do not affect governance integrity
Each chain enforces correctness independently.
Long-Term Privacy Guarantees
Multi-chain execution does not accumulate metadata over time.
There is:
no shared address space
no unified transaction graph
no cross-chain behavioral fingerprint
Privacy does not decay as the system scales.
