As the backbone of every blockchain application, the consensus protocol is impacted by
numerous risks, namely resource requirements and energy consumption, which limit the
usage of blockchain. Applications such as IoT/IIoT cannot use these high-cost consensus
methods due to limited resources. Therefore, we introduce Delegated Proof of Accessibility
(DPoAC), a new consensus technique that employs secret sharing, PoS with random
selection, and an interplanetary file system (IPFS). DPoAC is decomposed into two stages …
