Buterin proposes a new Ethereum L2 road map focusing on security and finality

Suggests a 2-of-3 proof system based on ZK proofs and Optimistic proofs

Also, advocates are shifting to an open source funding model
Vitalik Buterin, co-founder of Ethereum, has released a new roadmap to improve the security and finality for Layer 2 (L2) Rollup solutions. This proposal aims to address the current challenges of achieving high scalability as well as user trust in the Ethereum ecosystem.
The core plan is based on a novel “2-of-3” proof system, which combines three different types of transaction verification mechanisms simultaneously.
These mechanisms include zero-knowledge (ZK), standard optimistic proofs and proofs generated in trusted execution environments (TEEs).
ZK proofs are a cryptographic way to ensure the validity of a transaction without revealing any underlying data. Optimistic Proofs, on the other hand, assume that submitted L2 transactions will be valid by default, but include a challenge period to allow independent verifiers dispute potentially fraudulent activity.
TEEs use specialized secure hardware to execute code in a private and safe manner, providing another form of verification.
In this proposed multiproof system, L2 transaction would only be finalized on Ethereum if at least two of the three different proof mechanisms agree on the outcome. This design reduces the reliance on a single proof system’s assumptions about security and theoretically improves overall rollup security for users.

What are Buterin’s Stage 2 Rollups?
Buterin’s roadmap outlines the criteria for moving to Stage 2 rollups. The goal is to provide near instantaneous transaction confirmations, a high level of finality, and a strong failure resistance even in semi-trusted environment.
According to the proposal, Stage 2 upgrades would still be delayed by Ethereum’s standard 30 day upgrade delay mechanism. This delay is important for maintaining network stability and security when major software transitions are taking place.
The plan also addresses Ethereum’s scaling issues. Upgrades like Pectra or Fusaka are set to increase data accessibility, potentially enabling rollups that can handle up to 72 blobs, resulting in faster and cheaper transactions.
What are the broader implications?
As Ethereum’s L2 solution matures, achieving faster finality as well as increased trust are of paramount importance for scalability. Buterin’s strategy would not only increase security, but also align Ethereum’s commitment to minimization of trust and decentralization.
Buterin also advocates for a shift in the crypto community from public goods funding towards open-source funding. He argues that ‘public goods’ are susceptible to social biases and often prioritize perception over actual impact. Buterin believes by focusing on open source funding, the focus shifts to transparency and projects that deliver tangible benefit to the ecosystem.

This could be a great thing for Ethereum, as it would strengthen its infrastructure and increase the transaction efficiency. If this is a huge success, it may also promote sustainable development practices in the blockchain community.
