ECOIN Supplementary Design Notes: Museum, NFT, and Design Scenarios

This record presents applied design notes and exploratory implementation scenarios derived from the ECOIN framework. The materials included here focus on museum-oriented applications, design schematics, and circulation-based funding or participation models. These documents are not prescriptions, policy proposals, or finalized implementations, but illustrative examples of how ECOIN may be explored in practice. This record is intended as a supplementary companion to the main ECOIN framework paper (https://doi.org/10.5281/zenodo.18224621), which presents the core theoretical structure.
