OwnIt / Rangkai – Open Source Marketplace for Global Small Businesses

Rangkai Protocol is a modular, decentralized marketplace framework that separates responsibilities across layers—identity, transactions, reputation, logistics, trust & compliance, and governance. It enables automated dispute resolution, ratings, and hybrid KYC/anonymous interactions. Reference clients showcase how buyers, vendors, and logistics providers interact with each layer, serving as templates for real-world implementations. Multiple reference clients illustrate different business models, including general commerce, builder platforms, and logistics coordination.
