What is Zcash?

Zcash is an implementation of the "Zerocash" protocol. Based on Bitcoin's code, it intends to offer a far higher standard of privacy and anonymity through a sophisticated zero-knowledge proving scheme that preserves confidentiality of transaction metadata. Technical details are available in our Protocol Specification.

This software is the Zcash client. It downloads and stores the entire history of Zcash transactions; depending on the speed of your computer and network connection, the synchronization process could take a day or more once the block chain has reached a significant size.

Komodo Specific Notes

Dependencies

#The following packages are needed:
sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib autoconf libtool ncurses-dev unzip git python zlib1g-dev wget bsdmainutils automake libboost-all-dev libssl-dev libprotobuf-dev protobuf-compiler libqt4-dev libqrencode-dev libdb++-dev ntp ntpdate

Komodo

git clone https://github.com/jl777/komodo
cd komodo
#./autogen.sh
#./configure --with-incompatible-bdb --with-gui
# This command might finish with: configure: error: libgmp headers missing. This can be ignored. so can libsnark directory missing error
./zcutil/fetch-params.sh

# -j8 uses 8 threads - replace 8 with number of threads you want to use
./zcutil/build.sh -j8
#This can take some time.

to update an existing version, git checkout dPoW if not on that branch already

git pull

./zcutil/fetch-params.sh

./zcutil/build.sh -j8

To reset the blockchain, from ~/.komodo rm -rf blocks chainstate debug.log komodostate db.log

Create komodo.conf

cd ~
mkdir .komodo
cd .komodo
pico komodo.conf
#Add the following lines to the komodo.conf file:

rpcuser=bitcoinrpc
rpcpassword=password
txindex=1
addnode=5.9.102.210
addnode=78.47.196.146
addnode=178.63.69.164
addnode=88.198.65.74
addnode=5.9.122.241
addnode=144.76.94.38
addnode=89.248.166.91

Start mining

#iguana documentation shows how to get the btcpubkey and wifstrs that need to be used

#bitcoin also need to be installed with txindex=1 and with rpc enabled

cd ~
cd komodo


#This will return your pubkey eg. "0259e137e5594cf8287195d13aed816af75bd5c04ae673296b51f66e7e8346e8d8" for your address
./src/komodo-cli validateaddress <yourwalletaddres>

#This will give the privkey of your wallet address
./src/komodo-cli dumpprivkey <yourwalletaddres>

#This will import the privkey to be sure the mined coins are placed into your wallet address
./src/komodo-cli importprivkey <yourwalletprivkey>

#To stop the daemon:
./src/komodo-cli stop

#This starts komodo notary - replace genproclimit with number of threads you want to use and add your pubkey
./src/komodod -gen -genproclimit=2 -notary -pubkey="0259e137e5594cf8287195d13aed816af75bd5c04ae673296b51f66e7e8346e8d8" &

#This will get the stats:
./src/komodo-cli getinfo

#To view the process:
ps -ef | grep komodod

#To stop the daemon:
./src/komodo-cli stop 
 
#To view komodod output:
tail -f ~/.komodo/debug.log

#To view all command
./src/komodo-cli help

ASSETCHAINS: -ac_name=name -ac_supply=nnnnn

Both komodod and komodo-cli recognize -ac_name=option so you can create a zcash fork from the commandline
