Description
Seyed Rahman Soleimani Nadaf and three co-authors design a lean blockchain system for patient records that can grow without slowing to a crawl, in a 2025 paper. Blockchains promise tamper-proof, shared health records, but classic designs buckle under hospital-scale volume and delay.
Their model, DHC, keeps each facility’s daily records in local dynamic blocks gathered into a local chain. Those chains periodically anchor into the wider network, while bulk data live off-chain under integrity checks. New data structures keep retrieval fast and storage light. The design targets the real constraints of clinics: privacy for patients, quick access in emergencies, and trust between institutions that do not fully trust each other.
