Applying Data Analysis to Ethereum Gas Usage to Develop Blockchain Cost Models

ConsenSys开发了各种分散的应用程序，这些应用程序在以太坊加密货币平台上运行。加密货币是一种数字资产，旨在作为实现金融交易的交换媒介，并用于身份验证和安全电子投票等目的。以太坊平台的一个主要弱点是缺乏对以太坊操作的每个操作代码的gas（即执行**操作的一组操作的单位价值）成本的准确估计，这导致在执行操作时**以太（以太币）超支或不足。用户需要使用以太币购买gas，并向矿工提供一定数量的gas以执行操作。对天然气成本的不准确估计可能导致矿工拒绝合同或操作失败。目前，以太坊社区使用简单的gas成本估算，这是通过以太坊改进建议（eip）提出的；然而，**没有详细的气体成本每个操作码计算系统可用。在本项目中，将收集与公共以太坊合约、其执行、相应硬件和消耗的gas成本相关的数据**，并使用数据分析算法进行分析，以确定典型以太坊**操作的适当gas成本。将对开发的模型进行比较，以找到一个准确且可更新的模型，作为计算通用以太坊操作gas成本的参考框架。

ConsenSys develops a variety of decentralized applications which operate on the Ethereum cryptocurrency**platform. Cryptocurrency is a digital asset designed to work as a medium of exchange to implement financial**transactions and for purposes such as identity verification, and secure electronic voting. A main weakness of the**Ethereum platform is the lack of accurate estimation of the gas (i.e. unit value for a set of actions to perform an**operation) cost per operator code for Ethereum operations, which result in overspending or underspending of**ether (Ethereum currency) when executing operations. Users require to purchase gas using ether, and offer a**certain amount of gas to miners in order to execute operations. Inaccurate estimation of the gas cost may result**in rejection of the contract by the miners or failure of the operation. Currently, Ethereum community uses simple**estimations of the gas cost, which are proposed through Ethereum Improvement Proposals (EIPs); however,**there is no detailed gas cost per opcode calculation system available. In this project, data associated with public**Ethereum contracts, their execution, their corresponding hardware, and the consumed gas costs will be collected**and analyzed using data analysis algorithms developed to identify the appropriate gas cost for typical Ethereum**operations. The developed models will be compared to find an accurate and updatable model as a reference**framework for calculating gas cost of generic Ethereum operations.
