Ethereum transaction times are challenging to predict accurately due to factors like varying gas prices and data collection methods.The study examines processing times based on real-time data from Etherscan and EthGasStation for November to December 2019.Issues arise from discrepancies in block and processed timestamps, impacting transaction processing time estimates.Despite limitations, Etherscan remains a key tool for transaction monitoring in the Ethereum network.Gas prices are categorized to simplify analysis, with a focus on very cheap, cheap, regular, expensive, and very expensive prices.Alpha centrality is used to rank prediction models, highlighting the efficiency of linear regression for transaction time estimation.The study stresses the impact of network dynamics, hard forks, and market influences on transaction processing times in Ethereum.Data collection challenges prompt the need for more robust methods to gather accurate transaction processing time data.The study's findings serve as a snapshot of transactional history in Ethereum during the specified period, subject to contextual variations.Future studies are encouraged to analyze different time frames and factors influencing transaction processing times in various blockchain platforms.
