#Getting the source
Clone the DeltaChain repo :

#Dependency management
Simply run:
make dep
If you keep getting network error, it is suggested to use Go Module Proxy.
#Building
To build the main app delta, just run
make
or build the full suite:
make all
If no error reported, all built executable binaries will appear in folder bin.
#Running Delta
Connect to DeltaChain's mainnet:
bin/delta --network main
Connect to DeltaChain's testnet:
bin/delta --network test
or startup a custom network
bin/delta --network <custom-net-genesis.json>
example genesis config file can be found at genesis/example.json
To find out usages of all command line options:
bin/delta -h
--network value the network to join (main|test) or path to genesis file

--verbosity value log verbosity (0-9) (default: 3)
--max-peers value maximum number of P2P network peers (P2P network disabled if set to 0) (default: 25)
--p2p-port value P2P network listening port (default: 11235)
--nat value port mapping mechanism (any|none|upnp|pmp|extip:<IP>) (default: "none")

#Sub-commands
solo client runs in solo mode for test & dev
bin/delta solo --on-demand # create new block when there is pending transaction
bin/delta solo --persist # save blockchain data to disk(default to memory)
bin/delta solo --persist --on-demand # two options can work together
master-key master key management
# print the master address
bin/delta master-key
​
# export master key to keystore
bin/delta master-key --export > keystore.json
​
​
# import master key from keystore
cat keystore.json | bin/delta master-key --import
#Docker
This method needs running all commands by docker with the data directory mapped to the container.
#Pull image
docker pull deltachain/delta
#Export Master Key
First, start an interactive shell by docker:
docker run -it --rm\
-v {path-to-your-data-directory}:/root/.org.deltachain.delta\
--entrypoint /bin/sh deltachain/delta
Then export master key in the shell:
delta master-key --export > /root/.org.deltachain/keystore.json
Enter your password and check the generated file, then exit.
#Import Master Key
docker run -it --rm\
-v {path-to-your-data-directory}:/root/.org.deltachain\
deltachain/delta master-key --import
Follow the instruction by the program, input the KeyStore and also the password.
#Check Master Key
docker run -it --rm\
-v {path-to-your-data-directory}:/root/.org.deltachain\
deltachain/delta master-key
This command will print the Master Key.
#Start the Authority Masternode
docker run -d\
-v {path-to-your-data-directory}:/root/.org.deltachain\
-p 127.0.0.1:8669:8669 -p 11235:11235 -p 11235:11235/udp\
--name delta-node deltachain/delta --network main --skip-logs
