Deploy a consumer chain in a test environment and inspect its validator set.
Independent lab
Compare three security models in writing for a Cameroonian public-sector chain.
Security angle
Borrowed security moves risk onto the provider chain; it does not remove it.
Assessment
Comparative security-model note, defended before the group.
