Preconfirmations & The Future of Rollups — Livestream Recap
Recently, Puffer UniFi AVS was awarded a grant from EigenCloud to support the development of its preconfirmation network.
Built on EigenCloud, Puffer UniFi AVS enables economically secured preconfirmations, allowing rollups to deliver faster execution while remaining aligned with Ethereum’s validator security.
Following the announcement, we hosted a livestream featuring Amir Forouzani (Co-Founder of Puffer), Kunz (BD Lead at EigenCloud), and Puffer Intern as host to discuss the future of rollups, decentralized sequencing, and how preconfirmations backed by restaked ETH can improve performance and trust guarantees for onchain infrastructure.
You can watch the full conversation on our YouTube channel, and below you’ll find the transcript and summary of the discussion.
Livestream Recap
1. Introduction
This livestream follows the recent announcement that EigenCloud has awarded a grant to support Puffer UniFi AVS.
The discussion focused on:
- Preconfirmations as infrastructure
- Decentralized sequencing
- Crypto-economic security
- Institutional adoption
- The long-term scaling roadmap for Ethereum
2. What is Puffer UniFi AVS?
Speaker: Amir (CEO, Puffer Labs)
Puffer UniFi AVS is an Actively Validated Service (AVS) that provides crypto-economic security for Puffer’s preconfirmation network.
What problem does it solve?
Today’s rollups face two major issues:
- Latency
- Centralized sequencing
Puffer’s preconfirmation network delivers:
- Microsecond to millisecond transaction guarantees
- Near–TradFi speed UX
- Preconfirmations backed by economic security
- Compatibility with both:
- Based rollups built from Ethereum’s validator layer
- Existing L2s seeking higher performance
Instead of relying on centralized sequencers, UniFi AVS introduces economically secured preconfirmations, improving speed without sacrificing Ethereum alignment.
3. Why EigenCloud Backed Puffer
Speaker: Koons (BD Lead, EigenCloud)
EigenCloud supported Puffer for several key reasons:
1. Clear Product-Market Need
Preconfirmations directly address:
- Latency bottlenecks
- UX friction in rollups
2. Strong Team Credibility
Puffer has successfully shipped:
- Liquid restaking
- Based rollup infrastructure
3. Alignment with EigenLayer Vision
UniFi AVS leverages:
- Restaked ETH
- Shared Ethereum security
- Existing operator networks
This avoids bootstrapping a separate validator set.
4. Thoughtful Crypto-Economic Design
Puffer carefully designed:
- Slashing conditions
- Operator incentives
- Enforceable trust mechanisms
- Capital efficiency
The result is infrastructure-grade security backed by restaked Ethereum.
4. Decentralized Sequencing & Based Rollups
Puffer has been vocal about decentralized sequencing — but historically, decentralizing sequencers meant:
- Higher latency
- Inefficiency
- Misaligned incentives
UniFi AVS changes that.
Key Innovation: Incentive Alignment
Puffer redesigned the incentive layer between:
- Rollup owners
- Infrastructure providers
- Ethereum validators
This enables:
- Based sequencing
- Trust-minimized L1<>L2 communication
- L2<>L2 composability
- Removal of reliance on centralized sequencers
The goal is not just scaling — but preserving Ethereum’s neutrality and composability while scaling sustainably.
5. Adoption & Rollup Pipeline
Puffer spent ~6 months designing incentives alongside rollup developers.
First Phase:
- UniFi AVS will initially serve:
- Puffer UniFi based rollup
- Based appchains launching on testnet in March
Upcoming Launch:
A trading platform will launch on Puffer UniFi Based Rollup and leverage preconfirmations.
Over time, preconfirmation services will expand to additional rollups.
6. The Grant: Expectations & Milestones
EigenCloud described the grant as an alignment grant, not a conditional milestone grant.
Focus Areas:
- Onboarding professional infrastructure providers
- Creating a demand flywheel
- Supporting testnet → mainnet transition
- Increasing volume processed via preconfirmations
As usage scales, follow-on grants may be considered.
7. How the Grant Accelerates Puffer
From Puffer’s perspective, grants serve as:
- Validation signals to developers
- Confidence markers for auditors
- Assurance for institutional participants
The grant will help:
- Incentivize early preconfirmation users
- Offer sequencing fee rebates
- Support ecosystem bootstrapping
- Enable gas sponsorship via account abstraction
- Strengthen institutional outreach
Historically, Puffer has received Ethereum Foundation grants — this continues that trajectory of research-backed infrastructure delivery.
8. Institutional Adoption Path
What Institutions Care About:
- Speed (TradFi-level execution)
- Compliance capabilities
- Privacy options
- Infrastructure outsourcing
- Downside risk protection
How Puffer + EigenCloud Address This:
- Microsecond-level execution
- Gateway-based compliance extensions
- Potential privacy enhancements (coming soon)
- No need for institutions to run complex infra
- ~$5B in restaked economic security backing operations
- Slashing-backed accountability
This reduces counterparty risk and provides enforceable trust guarantees.
Puffer expects institutional rollups to launch using this architecture in the near future.
9. Long-Term Vision
EigenCloud’s goal:
Productive use of restaked capital and rewarding operators as ecosystem demand grows.
Puffer’s goal:
Builder-first, research-backed scaling solutions tightly connected to Ethereum’s base layer.
Everything Puffer builds — liquid restaking, rollups, AVS — connects back to Ethereum’s validator layer and shared economic security.
10. Closing Notes
Both teams expressed strong alignment around:
- Scaling Ethereum sustainably
- Preserving neutrality
- Enabling institutional-grade infrastructure
- Bringing preconfirmations into mainstream usage
More announcements are expected in the coming months.
