Measuring Ethereum Transaction Processing Delays
- The article focuses on measuring Ethereum transaction processing delays and the challenges of obtaining accurate timestamps in the blockchain network.
- To compute transaction processing times, pending and processed timestamps need to be obtained, which is a complex task due to decentralized nature of Ethereum.
- The study evaluates the accuracy of pending timestamps obtained from Etherscan and discusses the process of monitoring transactions to determine processing times.
- The authors describe the steps involved in obtaining pending timestamps, including submission, broadcasting, and detection by monitoring tools.
- A detailed experiment was designed to compare submitted timestamps with pending timestamps for transactions sent across various gas price categories.
- Results show that Etherscan is able to detect pending transactions within 1 to 2 seconds in the majority of cases, indicating a small and stable lag between submission and pending timestamps.
- The study conducted by authors from Queen’s University and Huawei in Canada is available on arxiv under a CC BY-NC-ND 4.0 DEED license.
- Challenges in obtaining accurate timestamps include the decentralized nature of Ethereum and limited visibility into pending pools of miners.
- The process of obtaining pending timestamps involves monitoring Etherscan's nodes and pending transactions webpage to approximate the original timestamps.
- The accuracy of collected pending timestamps was evaluated through a program that sent transactions at various gas prices over a 40-hour period, showing small and stable lag times.
