Feedback mechanisms are the backbone of resilient, scalable systems. In distributed systems, active monitoring and backpressure ensures the system’s overall stability. Similarly, horizontal scalability relies on dynamic monitoring to provision resources in response to demand. Dynamic auto-scaling and spot pricing are all standard these days. It wasn’t always the case;... [Read More]

In “Quantifying the Value of Revert Protection”, Zhu et al. explore how networks offering “free” revert protection shift costs across participants in the transaction supply chain. But who ultimately bears these costs, and why? Let’s break it down. [Read More]

History suggests that even the most resilient ecosystems can face decline from within. Arnold Toynbee examined the lifecycle of civilisations and concluded, “Civilisations die from suicide, not by murder”. This applies just as much to modern technological ecosystems like Ethereum. [Read More]

Protecting users from “drainers” has long been a challenge on Ethereum. These contracts trick users into signing harmful transactions, often disguised as simple token swaps. While wallets rely on transaction simulations to combat these attacks, simulations frequently fall short in preventing fund loss. In this post we will explore how... [Read More]
