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 […]
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 […]
