Double-spending problem
The double-spending problem is one of the fundamental challenges in digital currencies and decentralized systems like blockchain. It refers to the risk that a digital currency, such as Bitcoin or….
Hybrid consensus models
Hybrid consensus models are an emerging approach in blockchain technology that combine the benefits of multiple consensus algorithms to address the limitations of individual mechanisms. These models aim to improve….
Proof of History (PoH)
Proof of History (PoH) is a novel consensus algorithm designed to improve the scalability, speed, and efficiency of blockchain networks. Unlike traditional consensus mechanisms like Proof of Work (PoW) and….
Proof of Authority (PoA)
Proof of Authority (PoA) is a consensus algorithm that operates on the concept of identity and trust rather than computational power or stake in the network. PoA is typically used….
Practical Byzantine Fault Tolerance (PBFT)
Practical Byzantine Fault Tolerance (PBFT) is a consensus algorithm designed to ensure that a distributed system, such as a blockchain network, remains functional even if some of its participants (nodes)….
Delegated Proof of Stake (DPoS)
Delegated Proof of Stake (DPoS) is a variation of the traditional Proof of Stake (PoS) consensus mechanism used in blockchain networks. It aims to improve the performance and scalability of….
