and 77% reduction in signature formation period. In addition, Blockchain-STS saves

47.9% more power than Winternitz-OTS +. The suggested Blockchain-for-IoT is a

general architecture that can be used after customizing miners for various kinds of

IoT utilization (such as smart houses, clever towns, smart grids, or VANETs, etc.).

The future study emphasizes the protocols to ensure safe data transfer among IoT

nodes and the P2P network. In addition, the proposed architecture can be improved

in the future to accommodate complex situations such as complex index modification

as several transactions occur or concurrently prune.
