GravityCoin GXX: Hard Fork
BitcoinZeroX will be awarded to Bitcoin and HEXXCOIN holders at a ratio of 1:1. i.e you get 1 BZX for every HEXX or for every BTC that you own. BitcoinZeroX will be superior to Bitcoin private in terms of anonymity because it is based on the zerocoin protocol and not the ZK-snarks protocol as explained above.
What is a hardfork?
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, changes are periodically introduced into it. A hard fork represents changes that are not compatible with previous versions of software supporting the cryptocurrency network. In order to continue to mine the cryptocurrency, miners need to update the software.
In some cases, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash and EthereumPoW.
