Pythia

Currently only supports Linux and OSX systems.

On windows, you can use the cli-client using WSL2.

This is a great guide for installing WSL2 on Windows 10+ by OMG!Ubuntu.

If you're running on Linux or WSL2, be sure that you have OpenCL installed using these commands before proceeding:

sudo apt update
sudo apt install ocl-icd-opencl-dev

Installation

1. Install go-lang https://golang.org/doc/install
2. You should now be able to run the commands in the execute section

Execute

First of all, be sure to clone this repo

git clone https://github.com/zapproject/pythia

Then, create a file in the root of the cloned project and call it config.json.

Configuring your miner

Before running the miner, edit your config.json file so that you can add your publicAddress, privateKey and Contract Addresses:

1. paste this template in the file:

    {
        "zapTokenAddress": "0x09d8af358636d9bcc9a3e177b66eb30381a4b1a8",
        "contractAddress": "",
        "nodeURL": "https://data-seed-prebsc-1-s2.binance.org:8545",
        "vaultAddress": "",
        "publicAddress": "",
        "privateKey": "",
        "serverHost": "0.0.0.0",
        "serverPort": 5001,
        "localPort": 6363,
        "ethClientTimeout": 3000,
        "trackerCycle": 100,
        "gasMultiplier": 1,
        "gasMax":30,
        "serverWhitelist": [
        ],
        "useGPU":false,
        "trackers": [
            "balance",
            "disputeStatus",
            "gas",
            "tokenBalance",
            "indexers",
            "newCurrentVariables",
            "currentVariables"
        ],
        "dbFile": "zapDB",
        "disputeTimeDelta": "600s"
    }

Note You have the choice of using environment variables instead of editing the config.json. You can see the available environment variables here

2. Pay special attention to the contractAddress and vaultAddress fields, update them with the ones in this file.

3. Again, be sure to also add your publicAddress and privateKey to the new file as well. Remember, this public address is the BSC wallet address that should contain Testnet BNB and BSC ZAP.

You can get test Zap from here http://faucet.zap.org/, BSC Testnet faucet: https://testnet.binance.org/faucet-smart.

4. Add your publicAddress to the serverWhitelist field like this

{
    // ...
    "gasMax":30,
    "serverWhitelist": [
        "YOUR_PUBLIC_ADDRESS_HERE",
    ],
    "useGPU":false,
    // ...
}

5. Save config.json.

If you would like to test on a localhost BSC Testnet node, be sure have ZapHardhat running. https://github.com/zapproject/hardhat-bsc/.

Then, replace the nodeURL in the config.json with http://localhost:8545.

You can find an explanation of each field here.

Run a Single Miner Client

Run the following commands

1. ./release_build.sh
2. ./pythia mine

Will get your miner running.

In this setup, your client will also act as a datasever, and a miner.

The data server is set on port 5001. There is also a forex data server on port 6363.

These are default ports, but you can change if you so wish.

Remote Mining/Multiple Miners

This setup will allow you to run multiple miners on a single host address.

The Zap oracle network enables users to have a single data server provide data for multiple miner clients.

Here is an idea of how your setup can look like with this option:

Client A: Data Server

Client B: Miner Client
Client C: Miner Client
Client D: Miner Client
Client E: Miner Client
Client F: Miner Client

Your data server, Client A, can have the same config.json you configured earlier.

On Clients B to F, change the serverAddress in your config.json to the IP address or host address of Client A.

On Clients B to F, change their serverPort in config.json to the serverPort set in Client A's config.json. So by default, you can set it to 5001. Do the same for localPort, which is 6363 by default.

Next, go on Client A's config.json and update the serverWhitelist field with the public addresses of Clients B to F. Remember, these public addresses are the BSC wallet addresses that should contain Testnet BNB and BSC ZAP.

Here is an example of how your serverWhitelist should look like:

{
    "gasMax":30,
    "serverWhitelist": [
        "PUBLIC_ADDRESS_B_HERE",
        "PUBLIC_ADDRESS_C_HERE",
        "PUBLIC_ADDRESS_D_HERE",
        "PUBLIC_ADDRESS_E_HERE",
        "PUBLIC_ADDRESS_F_HERE"
    ],
    "useGPU":false,
}

Now, follow these steps to get your miners running.

1. Go on Client A and run the following commands ./release_build.sh then ./pythia dataserver
2. Go on Clients B to F and run ./release_build.sh then ./pythia mine -r

Your miners should now be running.

Supported Commands

Besides mine and dataserver you can also run the following commands based on your needs:

Pythia Commands

• mine (start mining, will run the dataserver and miner together)
• mine -r (indicates to mine utilizing a remote/independent dataserver)
• dataserver (runs the remote/independent dataserver, it does not do any mining)
• transfer [AMOUNT] [TO ADDRESS] (transfer BSC ZAP, TO ADDRESS is a BSC address and the AMOUNT is number of ZAP (eg. transfer 10 0xea... (this transfers 10 ZAP BSC tokens)))
• approve [AMOUNT] [TO ADDRESS] (AMOUNT of BSC ZAP to approve the TO ADDRESS to send this amount of tokens
• stake deposit (this command will stake 500,000 BSC ZAP to the vault contract; requirement for mining)
• stake request (you must request to withdraw your stake before withdrawing)
• stake withdraw (withdraws your stake, can only be ran 1 week after running stake request)
• stake status (shows whether or not your are staked)
• balance (shows your ZAP and BNB balance)

Pythia Flags

• --config (path to your config file, default is config.json in same Pythia root directory)
• --logConfig (location of logging config file; default path is Pythia root directory)

Running Disputes

from cli

4. Locate TimeStamp: %!(EXTRA *big.Int=XXX) in the terminal running the dataserver.
5. Copy the big.Int value XXX. (ex: For "TimeStamp: %!(EXTRA *big.Int=168473848)", we only need 168473848.)
6. Then run: ./pythia dispute new 1 {TimeStamp value `XXX` copied from step above} 4

Please reference CLI commands by running ./pythia --help.

BSC Testnet Miner Contract Addresses

See here to see all of the Pythia contract addresses

Config.json

tokenAddress (required)     - address of the Zap Token Contract

contractAddress (required)  - address of Zap Contract

vaultAddress (required)     - address of Vault Contract

nodeURL (required)          - RPC URL to the network (most likely BSC or localhost).

publicAddress (required)    - public address for your miner (note, no 0x)

privateKey (required)       - private key for miner node to sign transaction, without prefix 0x

ethClientTimeout (required) - timeout for making requests from your node

trackerCycle (required)     - how often your database updates (in seconds)

trackers (required)         - which pieces of the database you update

dbFile (required)           - where you want to store your local database (if self-hosting)

serverHost (required)       - ip address of dataserver

serverWhitelist (required)  - whitelists which publicAddress can access the data server.
                                Please have at least one in the array - your own publicAddress. See example below.

fetchTimeout                - timeout for requesting data from an API

gasMax                      - a max for the gas price in gwei (note: this max comes BEFORE the gas multiplier.
                                So a max gas cost of 10 gwei, can have gas prices up to 20 if gasMultiplier is 2)

heartbeat                   - an integer that controls how frequently the miner process should
                                report the hashrate (larger is less frequent, try 1000000 to start)

numProcessors               - an integer number of CPU cores/threads to use for mining.

disputeTimeDelta (required) - how far back to store values for min/max range - default 5 (in minutes)

disputeThreshold            - percentage of acceptable range outside min/max for dispute checking -

ENV Variables

If you wish to use environmental variables instead of config.json for some or all of your config fields, use

SET - export VARIABLE_NAME=arg ie. export PRIVATE_KEY=123ABC123ABC123ABC123ABC123ABC
CHECK - echo $VARIABLE_NAME
DELETE - unset $VARIABLE_NAME

Testing

You have a few options when you want to test pythia

Test Scripts

In the root of this project, run:

./runPkgTest.sh <PACKAGE_NAME>

This will run all tests, identified by *_test.go, in the given package. It will also give you coverage insights. If instead you'd like to test a specific test in a package run:

./runTest.sh <TEST_NAME> <PACKAGE_NAME>

e.g. ./runTest.sh TestDataServer dataServer

This will run the given <TEST_NAME> as long as it is inside a *_test.go file in the given <PACKAGE_NAME>.

Go test from CLI

You could of course also cd into the package of choice and run the standard go test [test flags...] e.g.

cd pow
go test -v -cover  # Test with increased verbosity and give a coverage analysis

You can also run individual test just like when running the ./runTest.sh script

cd pythia # while in the root of the project...
go test -v [test flags...] [PACKAGE_NAME] -run [TEST_NAME]

For more go test flags you can use, run this command in your terminal

go help testflag

Debug

Install

Delve is a debugger for the Go programming language. Follow the steps in this repo to install onto your machine.

For debugging, we needed to take out the -s and -w flags in the ./release-build.sh script.

1. Follow the steps above up until Execute - 1. Don't run the ./pythia command.
2. Instead run dlv exec ./pythia [command]. This allows the debugger to run the script.
3. Set breakpoint(s).
4. Enter continue command to allow the program to run till breakpoint.
5. Check variables using locals and/or print.
6. Step In and Out of functions with step and stepout.
7. Use restart to start over. Breakpoints will persist.
8. Use quit to exit debug mode.

Basic Debug Commands

continue | Run until breakpoint or program termination.
break | Sets a breakpoint. (EX. break tracker/index.go:39 That will set a breakpoint on line 39 in tracker.index.go file.)
breakpoints | Print out info for active breakpoints.
step | Single step through program.
stepout | Step out of the current function.
locals | Print local variables.
print | Evaluate an expression.
restart | Restart process.

More commands here $GOPATH/src/github.com/go-delve/delve/tree/master/Documentation/cli/locspec.md or type help when in debug mode.
