Ethereum Failed to Finalize: Impact and Implications: Ethereum's failure to finalize twice last week impacted the security and permanence of transactions on the network. A new tool called diligence fuzzing can help find code vulnerabilities in smart contracts, adding an extra layer of protection.
Last week, Ethereum experienced an event where it failed to finalize, meaning blocks were being missed and validators were not giving the necessary thumbs up for epochs to finalize and be permanently embedded into the blockchain. This event happened twice, and while finalization is typically a requirement for slashing conditions to go back and unwind blocks, the fact that Ethereum failed to finalize meant that these blocks were not as permanently embedded as they could have been. Preston Van Loon and Terrence Dow from Prismatic Labs, now part of Offchain Labs, will provide a deeper dive into the concept of finalization and what this event means for Ethereum. It's important to note that Prismatic is now owned by Offchain Labs, which is a sponsor of the Bankless podcast, and David and I hold Ethereum as an asset. Ethereum's inability to finalize is not ideal, as it can impact the security and permanence of transactions on the network. Additionally, there is a new tool called diligence fuzzing, an automated way to find code vulnerabilities for smart contracts, which can serve as an extra layer of protection for your smart contracts beyond typical code audits.

Ethereum network issue with clients handling old attestations: Some Ethereum clients struggled to handle increased network demands, leading to missed blocks and network outages. Clients have since adopted measures to exclude old attestations to mitigate this issue.
The Ethereum network experienced an issue where some clients were unable to respond to validator requests due to being bogged down with processing old, but valid, attestations. This issue was caused by the increased computational and networking requirements of handling a larger number of validators on the network. Prism and Techu were identified as clients that did not handle this scenario well, leading to a significant number of blocks being missed during the outage. To mitigate this issue, these clients have since adopted Lighthouse's model of excluding old attestations from consideration, rather than attempting to process them. This event is not believed to be malicious, but rather an unexpected behavior that was not well-handled by some clients. The incident highlights the importance of testing and preparing for unexpected scenarios as the Ethereum network continues to grow and evolve. Additionally, it underscores the need for continued development and improvement in how clients handle network conditions and the increasing demands placed on them by the growing number of validators.
Ethereum's network faced challenges in finalizing blocks due to insufficient blocks and attestations, leading to a loss for validators.: Ethereum's network experienced a test of its inactivity leak mechanism during degraded finalization service, resulting in a loss for validators but maintaining consensus.
Ethereum's beacon chain finalization process requires both a sufficient number of blocks and a supermajority of attestations to finalize an epoch. Last week, Ethereum experienced degraded finalization service due to a lack of both, leading to missed blocks and extended periods without finalization. During these periods, validators began to lose their balance faster as part of a mechanism designed to encourage faster finalization in the event of network division, such as during a hypothetical World War 3 scenario. This resulted in the burning of approximately 28 ETH and an average loss of $1 per validator. Despite the costs, this event served as a test of Ethereum's inactivity leak mechanism, ensuring the network can bridge the gap between divided Internet connections and maintain consensus.
High network congestion led to delays for some Ethereum applications relying on finality: During network congestion, proof of stake systems may experience delays or issues for transactions requiring finality, impacting applications and potentially leading to security vulnerabilities and financial losses.
During a period of high network congestion on Ethereum, some applications that rely on finality may have experienced delays or issues, while regular transactions continued to process. This inactivity leak, which affected clients like Prism, Teku, and Lighthouse, led to a diminished amount of block space and slightly higher gas prices. Although this issue didn't significantly affect most users, it highlighted the importance of finality in proof of stake systems. Without finality, we cannot be assured that transactions are irreversible and that the blockchain's history is immutable. In extreme cases, this could lead to security vulnerabilities and financial losses. It's crucial for Ethereum and other proof of stake networks to maintain finality and ensure that all transactions are processed efficiently and securely.
The Importance of Finality in Ethereum's Function as a Global Settlement Layer: Finality delays can lead to network disruptions, including longer challenge periods and potential validator ejections. Client teams and maintainers play a crucial role in addressing such issues and ensuring network stability.
Finality is a crucial aspect of Ethereum's function as a global settlement layer. When finality is delayed, it can lead to significant disruptions, including longer challenge periods and potential validator ejections. This was exemplified by an incident in which Ethereum's mainnet stopped finalizing, causing mass panic and a major disruption. Client teams and their maintainers play a vital role in addressing such issues, working tirelessly to resolve them and ensure the network's stability. This incident underscores the importance of understanding the emotional response to such events, as well as the technical details of finality and its implications for Ethereum's ecosystem.

Ethereum's resilience during a recent incident: Client diversity and LMD GHOST consensus mechanism ensured Ethereum's network continuity during a recent incident caused by under-optimization in the software.
The Ethereum network demonstrated remarkable resilience during a recent incident, thanks to a combination of client diversity and the consensus mechanism known as LMD GHOST. The incident, which lasted around 4 to 5 hours, was caused by under-optimization in the software. While diagnosing the issue wasn't difficult, the team opted for a perfect fix to avoid compromising other aspects of the client software. Client diversity played a crucial role in minimizing the impact of the incident, as Ethereum is not reliant on a single client. Furthermore, LMD GHOST, a consensus mechanism designed by researchers from the Ethereum Foundation, prioritizes liveness and ensured the continuity of the Ethereum blockchain during the incident. In summary, the Ethereum network's resilience during the incident can be attributed to the combination of client diversity and the LMD GHOST consensus mechanism.
Ethereum's prioritization of liveness during incident demonstrates network's antifragile nature: Ethereum's proof-of-stake design prioritizes network accessibility (liveness) over highest transactions per second rate, ensuring continuity during incidents and leading to ongoing improvements
Ethereum's proof-of-stake design and its prioritization of liveness proved resilient during a recent incident, demonstrating the network's antifragile nature. Unlike some other layer 1 blockchains, Ethereum prioritizes liveness over the highest transactions per second rate. This means that even during incidents, the network remains accessible, ensuring that users can continue to interact with it. The incident served as a valuable learning experience, leading to ongoing research and improvements in areas such as MEB burn and Proof of Stake (PBS). The interconnected nature of the Ethereum network means that progress in one area can lead to advancements in others. For instance, the discovery of a weakness in clients has been addressed. The contrast with blockchains that prioritize transactions per second over liveness, such as Solana, where network downtime can occur, highlights the importance of Ethereum's approach. Overall, the incident underscores the robustness and adaptability of Ethereum's proof-of-stake design.
Testing Ethereum's liveness and resilience: Ethereum's ability to process transactions in a timely manner is crucial, recent challenges like high gas fees and network congestion are tests, solutions like layer 2 scaling are being developed, and the foundation of a live network is essential.
Liveness, or the ability for a blockchain network like Ethereum to process and confirm transactions in a timely manner, is a crucial aspect of the network's functionality. Without liveness, the network would be unable to process any transactions at all, rendering it essentially useless. The speakers emphasized that Ethereum's recent challenges, such as high gas fees and network congestion, are tests of the network's liveness and resilience. They noted that solutions like layer 2 scaling and other mechanisms are being developed to address these issues, but that the foundation of a live and functional blockchain network is essential.
