Problem:
In IoBT, eventual consistency creates windows of vulnerability where adversaries can inject false or manipulated data. Ensuring integrity without requiring strong synchronization is critical.

Goal:
Build a lightweight blockchain or distributed ledger tailored for IoBT that ensures post-partition reconciliation and prevents data tampering.

Proposed Solution & Tasks:
Develop an append-only log system with cryptographic hashing and digital signatures.
Implement a lightweight blockchain consensus protocol suitable for low-power IoBT devices (e.g., Proof-of-Authority instead of PoW).
Test against false data injection attacks and partition/reintegration scenarios.
Compare performance with Conflict-Free Replicated Data Types (CRDTs).

Evaluation Criteria:
Integrity verification success rate (% of tampered data detected).
System overhead (memory, CPU, bandwidth).
Recovery time after partition rejoining.
Energy efficiency on constrained devices.

Suggested Tools & Platforms:
Blockchain Frameworks:
Hyperledger Fabric (permissioned blockchain, supports Proof-of-Authority).
Ethereum Private Testnet with Geth (can tune consensus protocols).
IOTA Tangle (DAG-based ledger) → lightweight, designed for IoT devices.

IoT Simulation:
NS-3 with DTN (Delay-Tolerant Networking) extensions → to simulate partitions and reintegration.
Cooja Simulator (in Contiki-NG) → deploy constrained IoBT nodes with blockchain overlays.

Validation Tools:
Wireshark for protocol analysis,
Log comparison for tampering detection.
