National Blockchain Framework (NBF) is an initiative of MeitY to aid for large scale adoption of Blockchain technology and enable trust for applications in the domain of e-Governance. It focuses on enabling Blockchain-as-a-Service and addresses the research challenges across various layers of the Blockchain stack. As a part of this initiative, NBF Blockchain-as-a-Service Technology Stack has been designed and developed for deployment of blockchain based applications with several components such as dashboard for automated network setup, generic smart contract layer, authentication and authorization functions and enabling the same through Open APIs. Dashboard also provides the details of the configuration, Generic APIs for recording and querying the smart contracts, management of the nodes in the network. Vishvasya is security audited across all layers and the Blockchain platform docker images are hardened. This technology stack, Vishvasya was launched by the Hon'ble Secretary, MeitY, Shri. S Krishnan on 4th Sep 2024 for large scale adoption of Blockchain application development.

Abstract:
Security information and Event Monitoring (SIEM) tools collect log data from critical resources which helps organizations to plan appropriate security assessment and reconciliation strategies. Root cause analysis of security risks needs data prevenance capabilities.
Blockchain Technology augments SIEM tools with data provenance capability so that an effective security framework can be built for organizations. In the article, we describe a unified and comprehensive security assurance framework that supports a tamper-proof, time-stamped, and decentralized storage repository that useful in assessing compliance with the security policy framework. We hope the architecture is suitable in the context of the National Blockchain Framework environment.
Abstract:
Hyperledger Sawtooth is an open-source blockchain platform under the Hyperledger enterprise initiative of the Linux foundation. This article starts with a brief introduction to Sawtooth, followed by detailed architecture. The key features of Sawtooth, and the operations of each module in the blockchain node are discussed here. Blockchain is a decentralized, distributed, immutable ledger system shared across a network introduced in 2008.
Smart contracts are simply programs stored on a blockchain that run when some conditions are met which are already defined. A smart contract is a self-executing contract whose terms of the agreement between the contract’s counterparties are embedded into lines of code.
