Like any other distributed system, the Blockchain technology relies on consensus algorithms in order to reach agreement and secure its network. Over the past few years, several kinds of consensus algorithms were created in the Blockchain ecosystem. In this paper, we present some main consensus ...

Since its inception, hundreds of alternative cryptocurrencies have been founded or split off from Bitcoin. The word “altcoin” is actually the short form of alternative coins which means all the other cryptocurrencies except the one bitcoin. Although both Litecoin and Bitcoin use blockchain technolog...
blockchain world calls it atomic.Komodo works atomically for independencefrom a dominant main chain. Custom consensus modules such as atokenization system,oracles,gateways to other coins,instant payment channel secured by bitcoin hashrate,dice, sudoku, etc, all of it is atomic utilizing the space ...
Cartesi is a Layer 2 platform composed of both blockchain and off-chain components. It allows large-scale verifiable computations to run that are easily integrated into smart contracts. DApps running inside Cartesi can process a virtually unlimited amount of data. ...

Many IoT-blockchain systems in which blockchain connections run on an infrastructure-based network, such as Wi-Fi or LTE, face a severe problem: the single point of failure (SPoF) (i.e., depending on the availability, an access point of an LTE base station). Using infrastructure-less net...
proposed a new methodology of creating a fully functional PKI that leverages the Ethereum Blockchain platform and its Smart Contract capabilities. Among other contributions, their proposed system offers a proper Preshared-Key (PSK) exchange and keystore concept that is decentralized and thus offers ...
Additionally, this technology can be integrated with federated learning, where models are trained locally on user devices and only updated weights are sent to the blockchain network. This allows users’ data to remain on their devices, minimizing the risk of data leakage. Autonomous vehicles are ...
This centralization of voting power undermines the main feature of the blockchain technology, that is the absence of a central authority. In order to avoid this problem, many alternative consensus mechanisms have been proposed. These alternative mechanisms use the PoS as the basic algorithm and ...
