VCash is the combined result of Bitcoin features integrated with Mimblewimble technology. It inherits Bitcoin's distribution mechanism and uses Grin's Mimblewimble implementation.
VCash uses the MergedMining method to mine with Bitcoin, that is to say, VCash blocks can be calculated when Bitcoin blocks are calculated. Generally speaking, the POW chain needs to take into account that the risk of the network being attacked is 51%. Since Bitcoin has the largest number of miners in the world and its hash power is widely distributed, VCash can easily obtain most of Bitcoin's hash power when supported by Bitcoin mining pools. This means that VCash has the same level of security as Bitcoin, so it is just as difficult to 51% attack it. VCash aims to be the most private and secure chain for storing value.
