Puffer Preconf Roadmap
Puffer Preconf is rolling out in three phases, each introducing new capabilities and security features. This phased approach allows us to iterate quickly, gather feedback, and ensure robust production deployment.
Overview
| Phase | Status | Key Features | Timeline |
|---|---|---|---|
| Phase 1 | 🟢 Current | Gateway delegation, reward forfeiture, Gattaca live | Live soon |
| Phase 2 | 🟡 Coming Soon | Multiple gateways, enhanced lookahead | TBA |
| Phase 3 | ⚪ Future | Full slashing, additional, advanced features | TBA |
Phase 1: Gateway Delegation & Initial Launch 🚀
Status: Live Soon
Phase 1 establishes the foundational infrastructure for Puffer Preconf with a focus on proving the technology and gathering real-world usage data.
Key Features
Gateway Model:
- Validators delegate sequencing rights to Gattaca serves as the first production gateway
- Gateways provide ~100ms execution preconfs for L2 transactions
Economic Model:
- No slashing for validators in Phase 1
- Reward forfeiture for missed block proposals
- Revenue sharing between L2 operators, validators, and gateway
- ETH-denominated rewards
User Protection:
- Economic incentives for honest behavior (reward forfeiture)
Supported Rollups:
- OP Stack rollups via Gattaca gateway
- Focus on based rollups seeking fast confirmations
What's Available Now
✅ For L2s:
- Integration with Gattaca gateway
- ~100ms execution preconfirmations
- Revenue sharing from preconf fees
- Production-ready for OP-based rollups
✅ For Validators:
- Opt-in to Puffer Preconf AVS on EigenLayer
- Use existing restaked ETH as collateral
- Earn additional rewards from preconf services
Limitations in Phase 1
- ❌ No slashing (only reward forfeiture)
- ❌ Single gateway provider (Gattaca)
- ❌ Limited to OP-based rollups
- ❌ Basic lookahead mechanism
Who Should Participate in Phase 1?
Ideal L2 Candidates:
- ✅ OP-based rollups seeking decentralization
- ✅ Based rollups needing faster confirmations
- ✅ Teams comfortable with early-stage production technology
- ✅ L2s with technical teams that can integrate rapidly
Ideal Validators:
- ✅ Already running validators on EigenLayer
- ✅ Comfortable with Commit-Boost software
- ✅ Seeking additional yield opportunities
- ✅ Willing to delegate to Gattaca gateway
Phase 2: Multiple Gateways & Enhanced Features 🌐
Status: Coming Soon
Phase 2 expands the gateway ecosystem and introduces enhanced coordination mechanisms.
Planned Features
Multiple Gateway Providers:
- Additional gateway providers onboarded
- Redundancy and competition improve service quality
Enhanced Lookahead:
- Support EIP-7917 Deterministic Lookahead
- Improved state sync between gateways
- Predictable handoffs minimize gaps
Expected Benefits for L2s
Redundancy:
- Multiple gateways eliminate single point of failure
- Automatic failover if gateway goes down
- Choose gateway based on performance or geographic location
Competition:
- Multiple providers drive better service quality
- Competitive pricing for preconf services
- Innovation in gateway technology
Timeline
🗓️ Expected Launch: TBA
We'll announce specific dates as Phase 2 approaches production readiness. Subscribe to updates or join our community for the latest information.
Phase 3: Full Slashing & Advanced Features ⚖️
Status: Future
Phase 3 introduces the complete security model with full slashing.
Planned Features
Full Slashing Implementation:
Based on current research recommendations:
-
Liveness Failures:
- Slash Amount: 1 ETH
- Trigger: Preconf promised but transaction not included, or batch not settled
- Recipient: Next gateway that had to cover + affected users
-
Malicious MEV Extraction:
- Slash Amount: 1000 ETH
- Trigger: MEV extraction performed by the gateway
- Recipient: Affected users
Slashing Infrastructure:
- Challenge period for disputed slashings
- Fault proof submission mechanism
- EigenLayer slashing integration
- Redistribution to affected parties (not burning)
Timeline
🗓️ Expected Launch: TBA
Phase 3 will launch after we've gathered sufficient data from Phase 1 and 2.
