Proof of Trust (PoT) Summary [Cryptocurrency consensus mechanisms]
In a Proof of Trust system, users in a network gain trust as they participate in special activities within the network. If a user tries to defraud the system, the trust is lost and they lose an equivalent amount in value (the cryptocurrency or token employed). In a Proof of Trust system, “trust” is staked […]
Proof of Space Time (PoST) Summary [Cryptocurrency consensus mechanisms]
Physicists have been discussing spacetime since the early 1900’s. A very smart person, by the name of Albert Einstein, modeled space as 4 dimensions rather than just 3. The axis were then X, Y, Z and …. time. Fortunately, you don’t need to understand Relativity Theory in order to grasp Proof of Spacetime! PoST Fast […]
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 […]
