AssetChain reimagines real estate investment through blockchain-based asset tokenization, facilitating fractional ownership and transparent trading. The system comprises Certificate of Ownership (COO) contracts, Fractionalizer contracts, and a Fractionalizer Factory. COO contracts mint digital certificates representing real estate assets, each containing essential metadata for integrity. Fractionalizer contracts tokenize assets into tradeable fractions, enabling broader investor participation. The Fractionalizer Factory acts as a decentralized marketplace, streamlining the deployment of new Fractionalizer contracts. A Fractional Order Book provides a transparent trading platform, enhancing liquidity and efficiency. AssetChain democratizes real estate investment, making it accessible to a wider audience and fostering trust through blockchain transparency. By digitizing assets and leveraging blockchain technology, AssetChain transforms real estate markets into a more inclusive and efficient ecosystem.
