This chapter describes Ethereum&s;s Layer 2 rollup-centric vision and the Ethereum Roadmap. We start by examining why scaling is a problem for Ethereum and how Ethereum aims to address this with the use of rollups, including optimistic rollups and zero-knowledge rollups. We conclude with a whistle-stop tour of the Ethereum Roadmap and the leading edge of Ethereum research and development.
For users of the Ethereum network, the gas price is a crucial parameter that determines how swiftly the decentralized consensus protocol confirms a transaction. This paper studies the statistics of the Ethereum gas price. We start with some conceptual discussion of the gas price notion in view of the actual transaction-selection strategies used by Ethereum miners. Subsequently, we provide the descriptive statistics of what we call the threshold gas price. Finally, we identify and estimate a seasonal ARIMA (SARIMA) model for predicting the hourly median of the threshold gas price.
