Blockchain for Model Based System Engineering

Our proposed concept is to use Blockchain Technology (BCT) to enhance the Model Based Systems Engineering (MBSE) team collaboration. Blockchains are a highly tamper-resistant Distributed Ledger Technology (DLT) in which all relevant transactions are immutably and identically recorded and stored in nodes of distributed networks to provide an authoritative Single Source of Truth (SST). Blockchains also support decentralized governance with nuanced privacy models. Smart Contracts (SC) are self-enforcing agreements realized by the automatic execution of agreed-upon computer code upon the endorsement of transactions between multiple parties. The benefits of our concept are SST, high security, improved trust, privacy preservation, transparency, accountability, traceability, and high cost effectiveness. The goal of our proposed concept is to provide the NASA MBSE teams with BCT tools to share models and implement collaborative processes in a secure, decentralized, and distributive environment.
