Traditional equity allocation models often rely on static ownership structures, which become outdated as member contributions evolve. The Build Dynamic Model introduces a transformative, blockchain-based framework that integrates Fair Market Value (FMV) assessments and API-driven automation to realign equity in real time. By leveraging smart contracts, tokenized shares, and structured protocols for evaluating diverse contributions— including time, intellectual property, and capital—this model ensures fairness, transparency, and adaptability across collaborative environments. The study explores the theoretical foundations, technological enablers, and practical implications of this model in the context of startups, decentralized organizations, and multidisciplinary ventures. Findings suggest that dynamic equity distribution mechanisms significantly reduce team conflict, improve incentive alignment, and foster sustainable collaboration. The paper concludes by recommending policy, legal, and technical considerations for broader adoption.
