Category How it solves 51% attack Problem Why VeriBlock is different
Build on top of another platform (like Ethereum) This assumes the platform has enough mining hash such that it is not susceptible to 51% attacks Building on a platform enforces constraints (block size, block time, transaction fees from other use cases of the network). Also, some functionality is not possible/practical to run on Ethereum/Bitcoin, and a specialized blockchain architecture is required to support the desired functionality. PoP can integrate with any altchain and consensus protocol
Centralized Authority certifies transactions/blocks as valid The CA chain does not have decentralized mining, and is therefore not susceptible to 51% attacks Most applications are built on blockchain to be decentralized, and having a centralized authority defeats the purpose PoP is fully decentralized
Master nodes stamp to Bitcoin The master nodes stamp fingerprints to Bitcoin, which is not susceptible to 51% attacks This centralizes control in a handful of master nodes (who can be manipulated/targeted/corrupted, or who may collude to perform an attack) PoP mining is completely decentralized, anyone can join and participate in the PoP mining process
