Caveat

◆ CKB Light Client is only activated on testnet, thus only light testnet is enabled in Neuron. CKB Light Client on Mainnet requires a hardfork on the mainnet in the future. ◆ CKB@v0.110 requires data migration, which is irreversible. Be cautious to start the migration without a backup.

On the other hand, we strongly recommend you to back up the old data before migrating, the ckb node data path can be found by clicking preference -> Data -> CKB Node Config & Storage. Because once the migration starts, the data will be no longer compatible with all older versions of CKB.

Light Client Mode

YouTube: https://youtu.be/tQm9YvgG7iEhttps://youtu.be/tQm9YvgG7iE

We are thrilled to introduce our new feature: Light Client Mode. This feature makes Neuron more practical and convenient, allowing you to manage your digital assets more easily. Please note that it is currently only available on the testnet, as activation on the mainnet will require a hardfork.

What is the light client model?

Light Client Mode is a connection mode of Neuron that connects to a built-in CKB Light Client. Compared to a full node, it downloads a portion of the blockchain data to obtain necessary information. This allows Neuron to access the CKB blockchain faster.

Light Client Mode Advantages

1. Higher synchronization speed: Light Client Mode enables faster synchronization of blockchain data, saving users' time and network bandwidth.
2. Less disk usage: Light Client Mode requires only a fraction of the blockchain data to be stored, resulting in less storage space requirement compared to a full node.

Using a MacBook Pro (13-inch, M1, 2020) device as an example, we conducted a realistic test of synchronization from block 0 to the latest block 9,380,828 (2023/05/22 Pudge network data):

• Light Client Mode: The synchronization process consumed about 5.5 hours and approximately 45MB of disk space during running. (The disk usage is related to the transaction count, and this test included 782 transactions.)
• Full Node Mode: It took about 36 hours to synchronize 107.8GB of data. (Excluding the time to find an assumed valid target block.)

In the above test scenario, using a light node compared to a full node reduced synchronization time by 84.7% and disk usage by 99.9%. (Please note that these numbers are for reference only and may vary depending on different equipment, network conditions, and account data.)

Light Client Mode Usage Scenarios

Compared to full nodes, light nodes require less disk space and network bandwidth, making them suitable for users who want to quickly access blockchain information without needing the full blockchain data. However, please note that for transactions containing time locks, Cheque contracts, or other operations that require full node data verification, you will need to switch to full nodes.
