YourDLT: Distributed Ledgers for You.

npm-badge size-badge dl-badge

Tool that lets you connect to existing YourDLT and/or Symbol distributed ledger networks.

This tool suite is powered by Using Blockchain Ltd, UBC Digital Magazine, dHealth Network and Symbol from NEM.

Note that we originally forked the nemtech/symbol-bootstrap repository to provide with more presets and network configurations. Using Blockchain Ltd does not own the blockchain networks to which this tool lets you connect.


Validate your environment by running:

node -v
docker -v
docker-compose -v

Make sure that your user can run docker without sudo:

docker run hello-world

Public Networks

This tool is compatible with multiple blockchain projects which are listed below:

Name Preset Name Link
dHealth Public Network dhealth dHealth Public Network
dHealth Test Network dhealthTestnet dHealth Test Network
Symbol from NEM mainnet Symbol from NEM
Symbol Testnet testnet Symbol from NEM
Custom private network bootstrap Catapult

Select one of the networks in the list above before you go on to setup your node.


Installing the software

$ npm i -g yourdlt

Check your setup

Use the -v flag to print the yourdlt version.

$ yourdlt -v
yourdlt/1.3.3 linux-x64 node-v14.16.0

Customize the node

You can customize your node with a custom preset configuration, let's for example touch ~/node_config.yml.

Put the following in this configuration file we just created, and replace your-awesome-node by the friendly name you want to set to your node:

    host: ''
    friendlyName: 'your-awesome-node'

If you already have a domain name DNS mapped to your server IP, you can specify it as the host of your node. This is optional and in case it is left empty, your node will be identified by its' IP address instead.

Useful configuration items among others:

  • beneficiaryAddress: Define a beneficiary address which will receive parts of the harvested fees on the node.
  • mainPrivateKey: Caution here, please only use this option if you want to use a specific account for this node.
  • remotePrivateKey: Caution here, please only use this option if you already linked your main account to a specific remote account.
  • vrfPrivateKey: Caution here, please only use this option if you already linked your main account to a specific VRF account.
  • maxUnlockedAccounts: Define the number of harvesting slots that are available for remote harvesting.
  • enableDelegatedHarvestersAutoDetection: Define whether you want to allow persistent delegated harvesting.
  • enableAutoHarvesting: Define whether you want your node to automatically start harvesting or not.

⚠️ If you put sensitive information in this file, please remind yourself to remove it after the node is configured and is ready to be run. We will make sure to point out at which point you can clean the custom configuration preset.

Setup your node

After you customized the node experience, you can now actually prepare the configuration of your network node. First we'll need to pick a so-called network preset, a target folder, an assembly and optionally specify a custom configuration preset.

$ yourdlt config -p bootstrap|mainnet|testnet|dhealth -t node -a peer|api|dual -c ~/node_config.yml

In the above, make sure to pick a network preset that is either mainnet for Symbol Mainnet, testnet for Symbol Testnet or dhealth for DHealth Public Network. Also choose one of the assemblies with the following descripions:

  • peer: Harvesting node (Creates blocks)
  • api: REST-enabled node (Relays information through an API)
  • dual: Full node (Creates blocks and relays information)

Following console output is an example after a successful yourdlt config execution:

$ yourdlt config -p dhealth -t node -a dual -c ~/node_config.yml

Setup your device

$ yourdlt compose -t node -c ~/node_config.yml

In the above make sure to replace node by the folder name you created using the config command just before. If you copy/pasted the command name from above, you can leave node here.

Following console output is an example after a successful yourdlt compose execution:

$ yourdlt compose -t node -c ~/node_config.yml

Start your node

Note that in the following command, we use the -d command line argument to denote a detached execution, this starts the node in a background process. To get information about your node, please use docker ps after running the following command:

$ yourdlt run -t node -d -c ~/node_config.yml
