Learn about the first friendly-fork of Zcash - Ycash
Ycash is a digital currency, like Bitcoin or Zcash. In fact, the software for Ycash is based on the software for Zcash, which in turn is based the software for Bitcoin. Like Bitcoin and Zcash, the total supply of Ycash is forever capped a 21 million coins. So, unlike government-issued paper cash, you never have to worry about inflation devaluing your Ycash. Ycash also shares something else in common with Zcash: shared blockchain history. The first 570,000 blocks of the Ycash blockchain are the same as the first 570,000 blocks of the Zcash blockchain. That means that everyone in control of Zcash private keys as of block height 570,000 (around July 18, 2019) will be able to use those private keys to access the same amount of Ycash. So, those that currently have a vested interest in the future of Zcash (by holding Zcash) automatically have a vested interest in the future of Ycash.
