Automated setup of regtest DAO - for Linux

The goal of these helper scripts is to set up a bisq DAO from scratch. The scripts run bitcoind in regtest mode for you and a seed node, alice and bob instances.

We assume the user is in the autosetup-regtest-dao directory. It is ok to move the directory, but please move it as a whole. Also bitcoin-qt, bitcoin-cli, bitcoin-tx, jq and bc has to be installed on the system. Do not change the shipped bitcoin.conf file as it will break things.

Steps to spin up a fresh DAO (we assume the user is in the autosetup-regtest-dao directory):

1. Set up bitcoin-qt to run in the autosetup-regtest-dao directory, it detects when the bitcoin-qt instance comes up and once it is ready the script queries the number of blocks. If there are less then 101 blocks (fresh start) the script generates 101 blocks for you so you have an available input that will be later used for the genesis tx creation.

./start_bitcoind.sh

Example output (note the below errors are normal and can be ignored):

user@host:~/bin/KanoczTomas/bisq/docs/autosetup-regtest-dao$ ./start_bitcoind.sh
error: Could not connect to the server 127.0.0.1:18443
Make sure the bitcoind server is running and that you are connecting to the correct RPC port.

2. Open a new terminal (preferably a new tab), go to the bisq folder and start the create_genesis.sh script. The script tests for a running bitcoind node in regtest, so make sure step 1 was successful.

cd bisq
./create_genesis.sh

example output:

user@host:~/bin/KanoczTomas/bisq/docs/autosetup-regtest-dao/bisq$ ./create_genesis.sh
testing if bitcoind is running: bitcoind is running, all is ok!
Please provide Alice's BSQ Address

3. We need the BSQ address of Alice. Go to the bisq directory and start the Alice instance. Wait until the instance starts up then go to DAO -> Receive and copy the BSQ address. Note the address starts with a B. Open a new terminal and enter the commands below to start Alice. Then wait for the gui to start and paste the BSQ address to create_genesis.sh which is still running from step 2.

cd bisq
./alice

4. Enter the amount of BTC in the create_genesis.sh script you want Alice to receive as BSQ. Example output:

user@host:~/bin/KanoczTomas/bisq/docs/autosetup-regtest-dao/bisq$ ./create_genesis.sh
testing if bitcoind is running: bitcoind is running, all is ok!
Please provide Alice's BSQ Address

1
Alice will receive 1000000.00 BSQ to Bn2iUHwJQTreQaoajKwnT6h7pYF9nCWULJA

5. We need the BSQ address of Bob. Go to the bisq directory and start the Bob instance. Wait until the instance starts up then go to DAO -> Receive and copy the BSQ address. Note the address starts with a B. Open a new terminal and enter the commands below to start Bob. Then wait for the gui to start and paste the BSQ address to create_genesis.sh which is still running from step 2.

cd bisq
./bob

6. Enter the amount of BTC in the create_genesis.sh script you want Bob to receive as BSQ. Example output:

Press enter to broadcast transaction, ctrl+c otherwise

7. verify if the tx shown as json is ok (the sum of outputs must be 2.5 to be valid). Note the script does not check the sum of the outputs as one needs to create an invalid genesis tx as well to test things. Press enter if tx looks ok.

8. Once confirmed the script will broadcast the genesis tx to the regtest blockchain and setup the config.sh file in the bisq directory which is used by the seed_node, alice and bob scripts. It populates the genesis txid and genesis block height so the instances can be launched accordingly. Example output:

... <output ommited - see step above>
Press enter to broadcast transaction, ctrl+c otherwise
Genesis txid is:

your conf file was modified accordingly
dao setup done

9. Start the seed node in full DAO node using the seed_node script. Make sure you are in the bisq directory.

cd bisq
./seed_node

10. Restart Alice and Bob you should see BSQ visible on the DAO page. Note the seed node is a full node and alice/bob are lite nodes in this setup.

Continuing work on the existing setup

1. Just run start_bitcoind.sh script and spin up seed node, alice and bob with respected scripts.

Clearing the DAO - for a fresh start

1. Run clean.sh. It will clear the bitcoind files and bisq files from ~/.local/share/ directory. Make sure your bitcoind/bitcoin-qt is stopped before running.

user@host:~/bin/KanoczTomas/bisq/docs/autosetup-regtest-dao$ ./clean.sh
DANGER! This will nuke your bitcoin regtest dir and bisq seed, alice and bob regtest dirs as well!
Press Enter to continue, otherwise ctrl+c
cleaned bitcoind home and bisq seed, alice, bob instances. The conf file for bisq was reset to dao=false
