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

Consensys开发了在以太加密货币**平台上运行的各种分散的应用程序。加密货币是一种数字资产，旨在作为交换媒介来实施金融**交易，并用于身份验证和安全电子投票等目的。**以太平台的一个主要弱点是缺乏对以太操作的每个操作员代码的气体(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超支或不足**以太(以太货币)。用户需要使用乙醚购买天然气，并向矿工提供**一定量的天然气才能进行作业。对天然气成本的不准确估计可能导致**矿工拒绝合同或作业失败。目前，Etherum社区使用简单的**天然气成本估算，这是通过以太改进建议(EIP)提出的；然而，**没有详细的每操作码天然气成本计算系统可用。在该项目中，将收集与公共**以太合同、合同的执行、相应的硬件以及消耗的天然气成本相关的数据**，并使用为确定典型以太**操作的适当天然气成本而开发的数据分析算法进行分析。将对开发的模型进行比较，以找到一个准确和可更新的模型，作为计算通用以太操作的天然气成本的参考**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.
