Benefits of Puffer Preconf for Layer 2s

Puffer Preconf offers unique advantages for different types of Layer 2 rollups. This guide explores the specific benefits for based rollups, traditional rollups, and the economic model that benefits all L2 operators.

For Based Rollups 🔄

Based rollups inherit Ethereum's security and liveness by having L1 validators sequence their transactions. However, they face a critical challenge: speed.

The Challenge

• Slow Confirmations: Limited by Ethereum's 12-second block time
• Economic Trade-offs: All transaction fees typically go to L1 validators
• User Experience: 12-second waits are too slow for many applications
• Competitive Disadvantage: Slower than centralized sequencer solutions

How Puffer Preconf Solves This

• ⚡ Speed: ~100ms execution preconfirmations eliminate the 12-second wait
• 💰 Revenue Sharing: L2 operators retain a portion of fees instead of ceding everything to L1
• 🔒 Maintained Security: Keep all the security benefits of being based on L1
• 🌐 Liveness Guarantee: Inherit Ethereum's robust liveness guarantees

tip

Based rollups using Puffer Preconf get the best of both worlds: the speed of centralized sequencers with the security and composability of Ethereum L1.

For OP Stack and Other L2s 🏗️

Traditional rollups using centralized sequencers offer fast confirmations but face centralization risks.

The Challenge

• Single Point of Failure: Centralized sequencer controls transaction ordering
• Trust Requirements: Users must trust the sequencer won't misbehave
• Censorship Risk: Centralized sequencer can censor transactions

Puffer Preconf as a Decentralization Path

Puffer Preconf enables OP Stack and other L2s to transition from centralized sequencers to decentralized preconf services:

• 🔧 Drop-in Integration: Compatible with existing OP Stack architecture
• ⚡ Maintained Speed: Keep ~100ms confirmations, no UX degradation
• 🌐 Decentralization: Distributed across multiple validators and gateways
• 🔒 Economic Security: 3M ETH backing instead of single operator trust
• 🔓 Censorship Resistance: Multiple gateways prevent single-point censorship

Featured: Gattaca Gateway for OP-Based Rollups

Gattaca provides production-ready preconf services specifically designed for OP-based rollups:

Architecture Highlights:

• Frags: Sub-block units enabling sub-100ms confirmations
• Lookahead Scheduling: Predictable sequencing rights assignment

Integration: OP Stack rollups can integrate with Gattaca gateway to receive immediate benefits

Economic Model: Aligned Incentives 💰

Unlike L2s where none of the fees flow to L1 validators or traditional based rollup models where all fees flow to L1 validators, Puffer Preconf introduces a revenue sharing model that creates sustainable economics for both L2 operators and Ethereum validators.

Revenue Flow (Phase 1)

1. User pays preconf fee for guaranteed execution
2. Fees collected by L2 fee contract
3. Distribution:
   • Portion to rollup/appchain owner
   • Portion to Puffer Preconf rewards manager contract
4. Rewards distribution based on validator and gateway performance

tip

Priority fees and congestion fees can be directed entirely to the rollup owner, giving L2 operators flexibility in their economic models.
