Hush Smart Chains - The z2z Platform

Hush Smart Chains are a way to create Zcash Protocol Proof-of-Work chains, with a focus on fully-shielded (z2z) chains for maximums privacy.

Creating a Hush Smart Chain

You will need the hush3 repo (and currently this is on our dev branch, will be released with our next 3.3.0 release):

git clone https://github.com/myhush/hush3
cd hush3
git checkout dev # this currently requires the dev branch until our 3.3.0 release
./zcutil/build.sh -j4 # uses 4 cores
cd src

As an example, we will make a replica of the cryptocoin Pirate (ARRR) in a single command:

hush-smart-chain -ac_name=ARRRUKIDDING \
-ac_supply=0 -ac_halving=388885 -ac_private=1 \
-ac_reward=25600000000 -addnode=45.76.84.111

This replica has exactly the same mining schedule as PIRATE as well as block reward. One notable exception is that all Hush Smart Chains are Pure Sapling, which means no 1.6GB download would be required to sync the ARRRUKIDDING chain.

One may note that the halving interval looks different than the 77777 that Pirate normally uses. This was the halving interval of the original Pirate chain, which the author mined on, but would have lead to all mining rewards being emitted in about 5 years. Komodo internally multiplies the interval by 5 to give a ~25 year emission and that is where 3888885 comes from.
