Ethereum Founder Buterin Lays Out Possible Futures For ETH Protocol

by

As a seasoned analyst with over two decades of experience in the tech and finance industries, I find Vitalik Buterin’s latest blog post to be both insightful and ambitious. Having followed Ethereum’s development since its early days, it is fascinating to see how the platform has matured and evolved.

On October 14, Vitalik Buterin, co-founder of Ethereum, shared his ideas for upgrading the Ethereum protocol in a blog post titled “The Merge: Future Improvements for Ethereum Protocol – Part 1.” This post primarily discusses technical advancements to its proof-of-stake (PoS) system, with an aim to boost stability, performance, and accessibility while mitigating centralization concerns.

As an analyst, I find myself reflecting on Ethereum’s transition from proof-of-work to proof-of-stake, or “The Merge,” almost two years ago. To put it simply, this shift to proof-of-stake has proven to be exceptionally stable, efficient, and effective in mitigating centralization risks. However, it’s important to acknowledge that there are still crucial areas where proof-of-stake needs further refinement.

Future Enhancements For Ethereum

One key point in this post is working towards swift finalization per transaction slot and lowering the entry threshold for network participation by decreasing the minimum amount of Ethereum required to validate transactions. At present, it takes around 15 minutes across 2-3 cycles to confirm a block, while one needs at least 32 ETH to become a validator. However, Buterin points out the challenge of balancing these factors: reducing staking requirements, expediting finality time, and keeping node management overhead to a minimum.

In simpler terms, he pointed out that currently, it takes about 2-3 rounds (approximately 15 minutes each) to complete a block, and you need 32 Ether to become a validator or staker. However, his goal is to speed up the process by finalizing blocks within a single time slot and making it possible for validators to stake with just 1 Ether. He emphasized that the high minimum requirement of 32 Ether is often cited as the main reason why more people are not staking solo, according to numerous surveys. (Buterin’s note)

To tackle these issues, he outlines various methods. One suggestion is enhancing current signature accumulation techniques, possibly with the aid of zero-knowledge proofs (ZK-SNARKs), to handle signatures from numerous validators in each timeframe. Another proposed strategy is the integration of Orbit Committees, a system where a randomly chosen mid-sized committee seals the chain while maintaining the attack cost properties. As he clarifies, Orbit leverages existing differences in validator deposit sizes to achieve maximum economic finality, all the while ensuring small validators maintain an equitable role.

Moreover, Buterin proposes a dual staking system with varying deposit thresholds. In this setup, only those with higher deposits participate in delivering economic finality. He admits that the risks are significantly influenced by the particular rights assigned to the lower staking tier. He cautions that some designs might inadvertently promote centralization.

To mitigate security concerns associated with Denial-of-Service (DoS) attacks on recognized validators, Buterin suggests utilizing Single Secret Leader Election (SSLE) methods. In simpler terms, this means concealing the identity of the validator who will generate the next block until it has been produced.

SSL (Secure Sockets Layer) protocols employ cryptographic methods to generate disguised validator identities, thus maintaining anonymity while only the legitimate owner of a disguised ID can produce a legitimate proof for proposing a block. This prevents others from discovering their identity in the process. However, Ethereum’s co-creator Vitalik Buterin recognizes the difficulties associated with this: “We prioritize keeping Ethereum as a relatively simple protocol, and we aim to avoid unnecessary complexity. SSL implementations we’ve encountered often involve hundreds of additional lines of spec code and introduce intricate assumptions in advanced cryptography.

Additionally, he delved into techniques to shorten Ethereum’s transaction validation time from the present 12 seconds down to a minimum of 4 seconds. He highlighted the importance of this reduction in validation times for enhancing user experience and supporting decentralized Layer 2 solutions more effectively. Some approaches include lessening slot durations and enabling proposers to release preliminary confirmations throughout a slot. However, Buterin advises on potential centralization threats and the necessity of suitable incentives, pointing out that “if we introduce an attester-proposer separation mechanism, then execution blocks won’t require Secure Socket Layer Encryption (SSLE), since we could depend on block builders to be specialized.

In addition to other crucial aspects, Buterin discusses the recovery of a 51% attack. He posits that while complete automation may not be feasible, we can strive for partial automation to prevent the perpetrators of such attacks from gaining an immediate and decisive advantage. Furthermore, he proposes increasing the threshold for block finalization from 67% to 80%, asserting that this would create a more secure environment compared to one where the opposing side could swiftly claim victory.

In wrapping up his blog post, Buterin emphasizes the necessity of being prepared for the possibility that quantum computers could breach existing cryptographic systems. He explains this as a reason to exercise caution in our expectations regarding the performance of proof-of-stake designs, and also encourages us to take a more active role in creating quantum-resistant alternatives.

At press time, ETH traded at $2,524.
