Light Clients and Parachain Data Verification

A light client lets you utilize all basic features of the chain such as fetching data and transferring tokens, but it does not require you to run a full copy of the entire blockchain or have to trust remote peers. Light clients fetch the required data that they need from a node with an associated proof to validate the data.

The light client connection type may be used only for Polkadot and Kusama in the current version of the Nova Spektr application.

If Polkadot or (and) Kusama are connected with Light clients then for their parachains Parachain Data verification is running. Parrachain Data Verification uses trusted data from relay chains (Polkadot, Kusama) to verify data from parachain remote nodes. This approach increases the reliability, security and sustainability of the parachain RPC connection.

If you’d like to turn on Light Client for Polkadot and (or) Kusama then:

1. Open the Network Management.

2. Click on the dropdown menu for the Polkadot or Kusama.

3. In the dropdown menu select Light Client.

4. Wait until the Light Client is starting.
