Integration of blockchain with hybrid lightweight cryptosystem

Blockchain is a blockchain platform that stores and distributes transaction records across the network's nodes. All actions with in system are confirmed by consensus mechanisms, and then once data is stored, it cannot be changed. The ledger Internet (BIoT) is a future Iot paradigm that secures IoT applications using blockchains. The blockchain's inherent security mechanism can provide IoT systems with conveniences such as availability, verification, permission, confidentiality, and integrity. There are some exceptions to the rule that the majority of IoT networks are naturally limited in terms of CPU processing and memory space. Blockchain has the drawback of requiring substantial amounts of energy & computing resources to operate. This makes BIoT installation more difficult. Due to its shorter key strings and improved security compared to public cryptosystems, elliptic curve crypto algorithms are gaining popularity. One of the most extensively used digital signature techniques is the elliptic digital signature system (ECDSA).
