let's ask some simple questions first:
1/ What hacash trying to solve in crypto space? Where is the demand for using hacash? (Sorry, I read your whitepaper but I see nothing)
2/ How does Hacash prevent 51% attack and chain-split?
3/ Why don't people use Bitcoin and Ethereum instead?
In Hacash, 51% attack protection is implemented by means of "node-notaries" (addresses with the largest number of coins) which sign blocks in the main network. A more complete understanding of this system can be obtained by reading the whitepaper.
