STTR Phase I: Blockchain ontology and services for monitoring and performing analytics on smart contracts

这个STTR项目更广泛的影响/商业潜力解决了“开放网络”开发人员，用户和监管机构面临的一个悖论：使用集中式平台创建者托管的门户网站与不断发展的去中心化金融（DeFi）应用生态系统进行交互。拟议的工作将提供一种新的开放式Web范式，以提高用户的可访问性以及在智能合约上编写和执行数据分析的能力。该方法将能够提高Web服务的可靠性和安全性，同时清除不良行为者。 提高智能合约的可访问性和分析能力，预计将有助于在一系列应用程序中释放更多的价值和解决方案，并创造新的商业机会，这些应用程序和商业机会都可以从动态合约中受益。STTR第一阶段项目提出构建一个与区块链相邻的元数据模型，为用户和开发人员增强智能合约的实用性和安全性。该项目将承担逆向工程智能合约的实际挑战，以概述一个元数据模型，该模型将增强服务的发现和安全性，为可组合应用程序创建一个脚手架。该方法将通过逆向工程的代码相似性分析和程序去混淆来组织区块链抽象，由开发人员进行编译时创建和发布元数据模型，并演示如何使用这些数据来构建可组合的应用程序用户体验。该项目将使用确定性服务以及元数据模型中的数据部署隐私保护定向广告框架。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this STTR project addresses a paradox faced by ‘open web’ developers, users, and regulators: the use of centralized platform-creator hosted web portals to interact with an evolving decentralized finance (DeFi) application ecosystem. The proposed work will instrument a new open web paradigm that will improve user accessibility and ability to compose and perform data analysis on smart contracts. The approach will enable improvement of web-service reliability and security while weeding out bad actors. Improving the accessibility and analysis of smart contracts is anticipated to help unlock further value and solutions across a range of applications and new business opportunities that can benefit from dynamic contracting.This STTR Phase I project proposes to build a blockchain-adjacent metadata model that enhances the utility and security of smart contracts for users and developers. The project will undertake the practical challenge of reverse-engineering smart contracts to outline a metadata model which will enhance discovery and security of services, creating a scaffold for composable apps. The approach will organize blockchain abstractions through code similarity analysis and program de-obfuscation by reverse engineering, instrument compile-time creation and publish metadata models by developers, and demonstrate how this data can be used to build a composable app user experience. The project will deploy privacy-preserving targeted advertising frameworks using deterministic services alongside the data from the metadata model.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
