Proof of Space (PoSpace) Summary [Cryptocurrency consensus mechanisms]
Proof of Space uses hard disk space as the value used to guarantee a participant’s stake in mining. By allocating disk space, the network participant provides value to the network, which uses this space to solve computational problems. Given low network bandwidth for a lot of regions, making it difficult to transfer large amounts of […]
Proof of Location (PoL) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Location consensus algorithm, users’ geospatial coordinates are accounted for as proof of value. This kind of algorithm is usually employed in cryptocurrency geomining systems. In a geomining application, users earn rewards for being at a certain place at a certain time. If, for example, a company wished to gather participants for […]
Proof of Authority (PoA) Summary [Cryptocurrency consensus mechanisms]
Proof of Authority is a consensus mechanism where members of a cryptocurrency network are identified and receive delegated powers to solve blocks. If they defraud the system their identity is at stake and they will either be prosecuted or booted from the network. This is a centralized system where a higher authority delegates mining powers […]
Proof of Burn (PoB) Summary [Cryptocurrency consensus mechanisms]
In the Proof of Burn (PoB) consensus mechanism, miners earn the right to mint the next block by burning some value in the blockchain. All proof systems are based on the principle that minting a block must incurr in some cost, otherwise fraudsters could inject invalid transactions into the blockchain. Bitcoin achieves this by making […]
