Vitalik Buterin outlines the Ethereum Strawmap vision
Ethereum co-founder Vitalik Buterin has unpacked key technical goals from the Ethereum Foundation’s newly published "strawmap," a long-range coordination document that sketches upgrades through 2029 aimed at drastically improving L1 performance, finality, security, and privacy. The strawmap—introduced by researcher Justin Drake—maps seven projected forks and groups improvements across consensus, data, and execution layers.
Key takeaways
- Slot times could fall from the current 12 seconds toward as low as 2 seconds.
- Finality may be reduced from minutes to roughly 6–16 seconds using a one-round BFT-style algorithm called Minimmit.
- Planned upgrades include erasure-coded P2P networking, fewer attesters per slot, and eventual quantum-resistant signatures.
How Ethereum plans to reach "fast L1"
Buterin emphasized an incremental approach: slot-time reductions would be rolled out cautiously, possibly following a "sqrt(2) at a time" cadence to balance throughput gains and network safety. Practical enablers include improved peer-to-peer block propagation via erasure coding, and consensus-level changes that cut signature aggregation overhead by limiting the number of attesters participating each slot.
Minimmit: one-round finality
Minimmit is a one-round BFT-style finality mechanism highlighted by Buterin as a core option for slashing finality times to the single-digit seconds range. Combined with reduced slot durations and network-level propagation enhancements, Minimmit could transform Ethereum UX by delivering near-instant settlement for many applications.
Broader roadmap goals and trade-offs
The strawmap lays out five "north stars": fast L1, gigagas L1 throughput, teragas L2 scaling, post-quantum security, and native privacy. Some of the most invasive changes—like migrating to hash-based, quantum-resistant signatures—would effectively replace large parts of Ethereum’s consensus stack in a gradual, ship-of-Theseus fashion, minimizing disruption while enabling stronger cryptography.
Coordination, not a mandate
Ethereum Foundation researchers stress that the strawmap is a coordination tool rather than a binding roadmap. It signals engineering priorities: faster user experiences, higher throughput targets, stronger post-quantum protection, and expanded native privacy. Each upgrade will be evaluated on safety, deployability, and real-world testing before activation.
As Ethereum pursues these layered improvements—spanning erasure-coded networking, attester count optimizations, Minimmit finality, and eventual quantum-resistant cryptography—the network is positioning itself for a decade of more ambitious L1 and L2 scaling, focused on user-facing speed and robust security.
