Razor-Go

Official node for running stakers in Golang.

Installation

Linux quick start

Install razor-go pre build binary directly from github and configure into host.

For linux-amd64

curl -sSL https://raw.githubusercontent.com/razor-network/razor-go/main/install.sh | bash

For linux-arm64

export PLATFORM=arm64

curl -sSL https://raw.githubusercontent.com/razor-network/razor-go/main/install.sh | bash

Check installation

razor -v

NOTE: To install the version you want, you can set VERSION: environment variable before running above command.

Docker quick start

One of the quickest ways to get razor-go up and running on your machine is by using Docker:

1. Create docker network

docker network create razor_network

2. Start razor-go container

docker run -d -it --entrypoint /bin/sh --network=razor_network --name razor-go -v "$(echo $HOME)"/.razor:/root/.razor razornetwork/razor-go:v1.0.0-mainnet

NOTE: we are leveraging docker bind-mounts to mount .razor directory so that we have a shared mount of .razor directory between the host and the container. The .razor directory holds keys to the addresses that we use in razor-go, along with logs and config. We do this to persist data in the host machine, otherwise you would lose your keys once you delete the container.

You need to set a provider before you can operate razor-go cli on docker:

docker exec -it razor-go razor setConfig -p <provider_url>

You can now execute razor-go cli commands by running:

docker exec -it razor-go razor <command>

Prerequisites to building the source

• Golang 1.15 or later must be installed.
• Latest stable version of node is required.
• Silicon chip based Mac users must go for node 15.3.0+
• geth and abigen should be installed. (Skip this step if you don't want to fetch the bindings and build from scratch)
• solc and jq must be installed.

Building the source

1. Run npm install to install the node dependencies.

2. If you want to build from scratch i.e., by fetching the smart contract bindings as well, run npm run build-all.

   Note: To build from scratch, geth and abigen must be installed in your system.

3. If you already have the pkg/bindings you can run npm run build instead of npm run build-all to directly build the binary.

4. If you want to build the binary without wanting to set the configurations use npm run build-noargs

5. While building the binary, supply the provider RPC url and the gas multiplier.

6. The binary will be generated at build/bin.

Commands

Go to the build/bin directory where the razor binary is generated.

cd build/bin

Set Config

There are a set of parameters that are configurable. These include:

• Provider: The RPC URL of the provider you are using to connect to the blockchain.
• Gas Multiplier: The value with which the gas price will be multiplied while sending every transaction.
• Buffer Size: Buffer size determines, out of all blocks in a state, in how many blocks the voting or any other operation can be performed.
• Wait Time: This is the number of seconds the system will wait while voting.
• Gas Price: The value of gas price if you want to set manually. If you don't provide any value or simply keep it to 1, the razor client will automatically calculate the optimum gas price and send it.
• Log Level: Normally debug logs are not logged into the log file. But if you want you can set logLevel to debug and fetch the debug logs.
• Gas Limit: The value with which the gas limit will be multiplied while sending every transaction.
• RPC Timeout: This is the threshold number of seconds after which any contract and client calls will time out.

The config is set while the build is generated, but if you need to change any of the above parameter, you can use the setConfig command.

razor cli

$ ./razor setConfig --provider <rpc_provider> --gasmultiplier <multiplier_value> --buffer <buffer_percentage> --wait <wait_for_n_blocks> --gasprice <gas_price> --logLevel <debug_or_info> --gasLimit <gas_limit_multiplier> --rpcTimeout <rpc_timeout>

docker

docker exec -it razor-go razor setConfig --provider <rpc_provider> --gasmultiplier <multiplier_value> --buffer <buffer_percentage> --wait <wait_for_n_blocks> --gasprice <gas_price> --logLevel <debug_or_info> --gasLimit <gas_limit_multiplier> --rpcTimeout <rpc_timeout>

Example:

$ ./razor setConfig --provider https://mainnet.skalenodes.com/v1/turbulent-unique-scheat --gasmultiplier 1 --buffer 20 --wait 30 --gasprice 0 --logLevel debug --gasLimit 2 --rpcTimeout 10

Other than setting these parameters in the config, you can use different values of these parameters in different command. Just add the same flag to any command you want to use and the new config changes will appear for that command.

Example:

$ ./razor vote --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --gasprice 10

This will cause this particular vote command to run with a gas price of 10.

Razor commands

Create Account

Create an account using the create command. You'll be asked to enter a password that'll be used to encrypt the keystore file.

razor cli

$ ./razor create

Docker

docker exec -it razor-go razor create

Example:

$ ./razor create
Password:

Import Account

If you already have an account created, and have it's private key, that account can be imported into the razor-go client. To do that, you can use the import command. You'll be asked the private key first and then the password which you want to encrypt your keystore file with.

razor cli

$ ./razor import

docker

docker exec -it razor-go razor import

Example:

$ ./razor import
🔑 Private Key:
Password:

Before staking on Razor Network, please ensure your account has eth and RAZOR. For testnet RAZOR, please contact us on Discord.

Stake

If you have a minimum of 1000 razors in your account, you can stake those using the addStake command.

razor cli

$ ./razor addStake --address <address> --value <value>

docker

docker exec -it razor-go razor addStake --address <address> --value <value>

Example:

$ ./razor addStake --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --value 1000

Note: --weiRazor flag can be passed to provide values in wei

If you have a 1000.25 razors in your account, you can stake those using the stake command with weiRazor flag.

Example:

$ razor addStake --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --value 1000250000000000000000 --weiRazor true

If you have a 5678.1001 razors in your account, you can stake those using the stake command with weiRazor flag.

Example:

$ ./razor addStake --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --value 5678100100000000000000 --weiRazor true

Staker Info

If you want to know the details of a staker, you can use stakerInfo command.

razor cli

$ ./razor stakerInfo --stakerId <staker_id_of_the_staker>

docker

docker exec -it razor-go razor stakerInfo --stakerId <staker_id_of_the_staker>

Example:

$ ./razor stakerInfo --stakerId 2

Set Delegation

If you are a staker you can accept delegation from delegators and charge a commission from them.

razor cli

$ ./razor setDelegation --address <address> --status <true_or_false> --commission <commission_percent>

docker

docker exec -it razor-go razor setDelegation --address <address> --status <true_or_false> --commission <commission_percent>

Example:

$ ./razor setDelegation --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --status true -c 20

Update Commission

If you are a staker and have accepted delegation, you can define your commission rate using this command.

razor cli

$ ./razor updateCommission --address <address> --commission <commission_percent>

docker

docker exec -it razor-go razor updateCommission --address <address> --commission <commission_percent>

Example:

$ ./razor updateCommission --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --commission 10

Delegate

If you want to become a delegator use the delegate command. The staker whose staker_id is provided, their stake is increased.

razor cli

$ ./razor delegate --address <address> --value <value> --weiRazor <bool> --stakerId <staker_id>

docker

docker exec -it razor-go razor delegate --address <address> --value <value> --weiRazor <bool> --stakerId <staker_id>

Example:

$ ./razor delegate --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --value 1000 --weiRazor false --stakerId 1

Claim Commission

Staker can claim the rewards earned from delegator's pool share as commission using claimCommission

razor cli

$ ./razor claimCommission --address <address>

docker

docker exec -it razor-go razor claimCommission --address <address>

Example:

$ ./razor claimCommission --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c

Vote

You can start voting once you've staked some razors

razor cli

$ ./razor vote --address <address>

docker

docker exec -it razor-go razor vote --address <address>

run vote command in background

docker exec -it -d razor-go razor vote --address <address> --password /root/.razor/<file_name>

NOTE: To run command with password flag with the help of docker, password file should present in $HOME/.razor/ directory

Example:

$ ./razor vote --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c

If you want to claim your bounty automatically after disputing staker, you can just pass --autoClaimBounty flag in your vote command.

If you are running an extra backup node, it is suggested to avoid performing few actions. So to do that you need to pass actions that need to be ignored as a value to flag --backupNode <actions_To_Ignore>. For now, we only support disputeMedians as actions to be ignored as a value for backup node.

$ ./razor vote --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --backupNode disputeMedians

If you want to report incorrect values, there is a rogue mode available. Just pass an extra flag --rogue to start voting in rogue mode and the client will report wrong medians. The rogueMode key can be used to specify in which particular voting state (commit, reveal) or for which values i.e. medians/revealedIds (medians, missingIds, extraIds, unsortedIds)you want to report incorrect values.

Example:

$ ./razor vote --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --rogue --rogueMode commit,reveal,medians,missingIds,extraIds,unsortedIds

Unstake

If you wish to unstake your funds, you can run the unstake command.

razor cli

$ ./razor unstake --address <address> --stakerId <staker_id> --value <value> --weiRazor <bool>

docker

docker exec -it razor-go razor unstake --address <address> --stakerId <staker_id> --value <value> --weiRazor <bool>

Example:

$ ./razor unstake --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --stakerId 1 --value 1000 --weiRazor false

Withdraw

Once unstake has been called, you can withdraw your funds using the initiateWithdraw and unlockWithdraw commands

You need to start the withdrawal process using initiateWithdraw command and once the withdraw lock period is over you can use unlockWithdraw command to get the RZR's back to your account.

razor cli

$ ./razor initiateWithdraw --address <address> --stakerId <staker_id>

$ ./razor unlockWithdraw --address <address> --stakerId <staker_id>

docker

docker exec -it razor-go razor initiateWithdraw --address <address> --stakerId <staker_id>

docker exec -it razor-go razor unlockWithdraw --address <address> --stakerId <staker_id>

Example:

$ ./razor initiateWithdraw --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --stakerId 1

$ ./razor unlockWithdraw --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --stakerId 1

Extend Lock

If the withdrawal period is over, then extendLock can be called to extend the lock period.

razor cli

$ ./razor extendLock --address <address> --stakerId <staker_id>

docker

docker exec -it razor-go razor extendLock --address <address> --stakerId <staker_id>

Example:

$ ./razor extendLock --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --stakerId 1

Claim Bounty

If you want to claim your bounty after disputing a rogue staker, you can run claimBounty command

NOTE: bountyIds are stored in .razor directory with file name in format YOUR_ADDRESS_disputeData.json file.

e.g: 0x2EDc3c6F93e4e20590F480272AB490D2620557xY_disputeData.json If you know the bountyId, you can pass the value to bountyId flag.

razor cli

$ ./razor claimBounty --address <address> --bountyId <bounty_id>

docker

docker exec -it razor-go razor claimBounty --address <address> --bountyId <bounty_id>

Example:

$ ./razor claimBounty --address 0x5a0b54d5dc17e0aadc383d2db43b0a0d3e029c4c --bountyId 5

You can also run claimBounty command without passing bountyId flag as it will pick up bountyIds associated to your address from the file one at a time.

razor cli

$ ./razor claimBounty --address <address>

docker

docker exec -it razor-go razor claimBounty --address <address>

Transfer

Transfers razor to other accounts.

Expose Metrics

Expose Prometheus-based metrics for monitoring

Example:

razor cli

Without TLS

$ ./razor setConfig --exposeMetrics 2112

With TLS

$ ./razor setConfig --exposeMetrics 2112 --certFile /cert/file/path/certfile.crt --certKey key/file/path/keyfile.key

docker

# Create docker network

docker network create razor_network

# Expose Metrics without TLS
docker exec -it razor-go razor setConfig --exposeMetrics 2112

# Expose Metrics with TLS
docker exec -it razor-go razor setConfig --exposeMetrics 2112 --certFile /cert/file/path/certfile.crt --certKey key/file/path/keyfile.key

Configuration

Clone repo and setup monitoring and alerting using Prometheus/Grafana

git clone https://github.com/razor-network/monitoring.git
cd monitoring

• If your staker is running via binary, then

  1. In ./configs/prometheus.yml, replace "razor-go:2112" with "<private/public address of host>:2112"

• For alerting you can add webhook in ./configs/alertmanager.yml, replace http://127.0.0.1:5001/ with your webhook URL. This will send you an alert in every 5min if metrics stops.

• If you are running multiple stakers and want to monitor via single grafana dashboard

  1. You need to update ./config/prometheus.yml, add new target block where job_name: "razor-go"

     - targets: ["<second-host-address>:2112"]
       labels:
         staker: "<staker-name>"
     

  2. Restart vmagent service docker-compose restart vmagent

Start monitoring stack

• You can spin all agents at once via

  docker-compose up -d
  

  Can check the status of each service via

  docker-compose ps
  

• You can open grafana at <private/public address of host>:3000, and get

  1. Can checkout Razor dashboard to monitor your staker.
  2. Insight of host metrics at Node Exporter Full dashboard.
  3. Containers Insight at Docker and OS metrics ( cadvisor, node_exporter ) dashboard.
  4. Can monitor alerts at Alertmanager dashboard.

NOTE: Configure firewall for port 3000 on your host to access grafana.

Troubleshoot Alerting

1. In docker-compose.yml uncomment ports for alertmanager and vmalert.

2. Configure firewall to allow access to ports 8880 and 9093.

3. Check you get alerts on vmalert via http://<host_address>:8880/vmalert/alerts. vmalert is configured to scrap in every 2min.

4. If you see alert in vmalert then look into alertmanager http://<host_address>:9093/#/alerts?, if you see alerts in there but you didn't get one then probably you need to check your weebhook.

Override Job and Adding Your Custom Jobs

Jobs URLs are a placeholder from where to fetch values from. There is a chance that these URLs might either fail, or get razor nodes blacklisted, etc. You can override the existing job and also add your custom jobs by adding assets.json file in .razor directory so that razor-nodes can fetch data directly from the provided jobs.

Shown below is an example of how your assets.json file should be -

{
  "assets": {
    "collection": {
      "ethCollectionMean": {
        "power": 2,
        "official jobs": {
          "1": {
            "URL": "https://data.messari.io/api/v1/assets/eth/metrics",
            "selector": "[`data`][`market_data`][`price_usd`]",
            "power": 2,
            "weight": 2
          },
        },
        "custom jobs": [
          {
            "URL": "https://api.lunarcrush.com/v2?data=assets&symbol=ETH",
            "selector": "[`data`][`0`][`price`]",
            "power": 3,
            "weight": 2
          },
        ]
      }
    }
  }
}

Breaking down into components

• The existing jobs that you want to override should be included in official jobs and fields like URL, selector should be replaced with your provided inputs respectively.

In the above example for the collection ethCollectionMean, job having jobId:1 is override by provided URL, selector, power and weight.

"official jobs": {
          "1": {
            "URL": "https://data.messari.io/api/v1/assets/eth/metrics",
            "selector": "[`data`][`market_data`][`price_usd`]",
            "power": 2,
            "weight": 2
          },

• Additional jobs that you want to add to a collection should be added in custom jobs field with their respective URLs and selectors.

In the above example for the collection ethCollectionMean, new custom job having URL https://api.lunarcrush.com/v2?data=assets&symbol=ETH is added.

 "custom jobs": [
          {
            "URL": "https://api.lunarcrush.com/v2?data=assets&symbol=ETH",
            "selector": "[`data`][`0`][`price`]",
            "power": 3,
            "weight": 2
          },
        ]

Logs

User can pass a separate flag --logFile followed with any name for log file along with command. The logs will be stored in .razor/logs directory.

razor cli

$ ./razor addStake --address <address> --value <value> --logFile stakingLogs

docker

docker exec -it razor-go razo addStake --address <address> --value <value> --logFile stakingLogs

The logs for above command will be stored at "$HOME/.razor/logs/stakingLogs.log" path

razor cli

$ ./razor delegate --address <address> --value <value> --weiRazor <bool> --stakerId <staker_id> --logFile delegationLogs

docker

docker exec -it razor-go razo delegate --address <address> --value <value> --weiRazor <bool> --stakerId <staker_id> --logFile delegationLogs

The logs for above command will be stored at "$HOME/.razor/logs/delegationLogs.log" path

Note: If the user runs multiple commands with the same log file name all the logs will be appended in the same log file.

Contract Addresses

This command provides the list of contract addresses.

razor cli

$ ./razor contractAddresses

docker

docker exec -it razor-go razor contractAddresses

Example:

$ ./razor contractAddresses

Setting up razor-go and commands using docker-compose

1. Must have docker and docker-compose installed

2. Building the source docker-compose build

3. Create razor.yaml at $HOME/.razor/

   vi $HOME/.razor/razor.yaml

4. Add in razor.yaml and use :wq to exit form editor

   buffer: 20
   gaslimit: 2
   gasmultiplier: 1
   gasprice: 0
   provider: <rpc-url>
   wait: 30

5. Create account , and note address.

   docker-compose run razor-go /usr
   /local/bin/razor create

6. Import account
