Validator Requirement

How to become a validator

Permissioned validator

To become a permissionless collator on Mandala Chain networks, you need to meet the requirements below.

Collator staking requirements

  • Bond: 3,200,000 KPG tokens (3.2M $KPG)

  • Meet hardware requirements

If your node stops producing blocks for one session, your node will be kicked out of the active set, and 1% of the bonded funds will be slashed. Running a node with low performance can lead to skipping blocks, which can lead to being kicked out of the active set.


Set your collator with: Extrinsics - CollatorSelection - Register as candidate | Onboarding takes n+1 session.

System requirements

A collator deploys its node on a remote server. You can choose your preferred provider for dedicated servers and operating systems. Generally speaking, we recommend you select a provider/server in your region. This will increase the decentralization of the network. You can choose your preferred operating system, though we highly recommend Linux.

Hardware requirements

Use the charts below to find the basic configuration, guaranteeing that all blocks can process in time. If the hardware doesn't meet these requirements, there is a high chance it will malfunction, and you risk being automatically kicked out and slashed from the active set.


Ensure your server is a bare metal only dedicated to the collator node; any unnecessary process running on it will significantly decrease the collator performance. We strongly discourage using a VPS to run a collator because of their low performance.

Collators are the nodes which require the most powerful hardware because they have short time frames to assemble a block and collate it to the relay chain. To run a collator, it is necessary to use a CPU of a minimum 4 Ghz per core and an NVMe SSD disk (SATA SSDs are unsuitable for collators because they are too slow).
