thus form the P2P network. Individual peer has sufficient storage and computing

capability to control a Distributed Directory (DD). The layer of communication pro-

vides communication among sensor peers and devices. Lastly, the records storage

facilities are provided in the DL Layer. The matches preserve information on behalf

of actuators and sensors in the aimed Blockchain-based IoT system [36]. Several

actuators and sensors are attached to each peer. When information from one of the

relevant sensors is received, a match creates a new deal and conveys it across the

P2P network. Different peers validate the performance and collect the new deal in

the ledger after reasonable verification (DL). We suggest a method that will assure

that a new transaction can be stored in DL only by trusted peers. For a DL integrated

into an IoT context, we have developed new transaction verification rules. The aimed

transaction confirmation laws allow the DL to connect input/output deals. Therefore,

each transaction has precisely one predecessor and one successor, “zero or one.” To

succeed in an actual transaction a, the Signs of b must validate a key earlier collected

in a. The transaction owner b (Owner B) may only sign the transaction later than

the transaction owner a (Owner A). In this process, Owner A serves as Owner B’s

sponsor. The consent given through the owner of an earlier collected transaction for

each new transaction removes the need for a traditional (PoW) process. Therefore,

we need not encapsulate single transactions within blocks, so our introduced DL
