The features such as secure, immutable, transparent, and anonymous makes Block...
Strictly speaking, dPoW is not a consensus algorithm because it's not used to achieve consensus on new blocks. Rather, it's a security mechanism that makes blockchains resistant to a 51% attack in which a single entity can control the majority of the hash rate on a blockchain network an...
Proof of workis the first Blockchain algorithm introduced in the blockchain network. Many blockchain Technologies use this Blockchain consensus model to confirm all of their transactions and produce relevant blocks to the network chain. Thedecentralization ledgersystem collects all the information related...
This research aims to integrate IoT with blockchain technology to securely manage and monitor sensitive patient health data in critical care environments, thereby improving the reliability and efficiency of patient monitoring systems. A hybrid blockchain architecture is employed to store ICU patient data...
The very first implementation of a distributed and trustless consensus algorithm isBitcoin’sproof-of-work(PoW) algorithm. PoW requires miners to solve complex cryptographic puzzles before they can add a block to the blockchain. In exchange for solving the puzzle, miners are rewarded with bitcoins...
The main benefit of blockchain technology, as we are all aware, is that it is decentralized. Usually, in a centralized space, authority is in charge of setting the regulations. But how do they come to a consensus in a decentralized setting?This is where the Blockchain consensus algorithm co...
Proof of Stake (PoS)[25]is aconsensus algorithmthat relies on the crypto-currency of the blockchain user. In a Proof of Stake system, the creator of the next block is determined by a random system that is, in part, dictated by how much crypto-currency a user holds or, in some cases...

Blockchain technology has emerged a solution for managing MEC services, with consensus protocols and data integrity checks that enable transparent and efficient distributed decision-making. In addition to transparency, the benefits from a security point of view are evident. Nonetheless, blockchain ...
This unique consensus mechanism incorporates time into the blockchain to reduce the load on network nodes during block processing. It operates like a cryptographic time stamp. This process eliminates solving for the time of transactions as it is in the proof of work (PoW) algorithm. For example...
