Introduction to Ecosystem Integration
Phase 4 represents the culmination of the WIA-LEG-006 standard, connecting digital asset inheritance to the broader WIA ecosystem and bridging blockchain systems with traditional legal infrastructure. No digital inheritance solution exists in isolationโit must interoperate with identity systems, legal frameworks, compliance tools, and financial services. This chapter explores how WIA-LEG-006 achieves comprehensive integration while embodying the ๅผ็ไบบ้ principle of serving all humanity.
