Security Model & Best Practices
xPrivFi is an experimental Layer-1 blockchain. Security depends on correct software, responsible users, and honest network participation. This page outlines the system’s security assumptions and essential precautions.
1. Protocol-Level Security
The XPF Layer-1 protocol is intentionally minimal to reduce attack surface. Every rule can be validated deterministically by a single full node.
- Proof-of-Work: RandomHash (iPoW), CPU-oriented and ASIC-resistant.
- Difficulty control: CP-Diff v1.0 targets ~6-minute block spacing.
- Deterministic validation: no scripting engine, no dynamic opcodes.
- Transparent ledger: all balances and state transitions are visible.
- No admin keys: no hidden minting keys or centralized control.
Consensus integrity relies on decentralized miners and consistent node software.
2. Privacy & Metadata Security
The Layer-1 chain is fully transparent today. No privacy guarantees exist at this time.
- No active shielded pool.
- No commitments or nullifiers in L1 state.
- CP-Shield v1.0 is research-only and not implemented.
- Metadata and transaction linking attacks are possible.
Privacy features will be introduced only after extensive security review and audits.
3. Node & Network Security
Running a node exposes you to typical peer-to-peer risks. Use secure environments and keep software up to date.
- Never expose RPC to the open internet.
- Use firewalls and proper server hardening.
- Verify downloads and builds when possible.
- Expect temporary forks or re-orgs during early development.
- Back up private keys — lost keys cannot be recovered.
4. HexGrid & Layer-2 Security
HexGrid is a Layer-2 mining mechanism. It does NOT modify Layer-1 consensus and cannot mint coins directly.
- L2 may fail independently of the blockchain.
- Reward errors on L2 do not affect L1 supply.
- Rewards always settle on L1 as standard transactions.
- Browser mining depends on local device security.
- L2 code is proprietary and evolves rapidly.
Participation in L2 is optional and carries separate risk from L1.
5. User Security & Best Practices
Personal security is critical — the network cannot recover lost funds.
- Back up keys securely and offline.
- Use encrypted storage and strong passwords.
- Never share private keys or seed phrases.
- Verify addresses before sending funds.
- Beware of phishing or fake wallet tools.
The network does not offer account recovery or custodial protection.
6. No Guarantees
xPrivFi provides no guarantees of uptime, performance, or continued development. Software is provided “as-is,” under applicable licensing.
XPF is experimental software. Use at your own risk.
