A persistent gap exists in realizing practical, scalable solutions for supply chain transparency systems that verifiably exclude forced and child labor. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

Achieving protocols for equitable benefit-sharing from genetic resources and digital sequence data at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.
