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
