Node sync status

☕️ Node Sync Rate

Based on this GCP VM (e2-standard-4 4vCPU, 16 GB memory, 610 GB SSD, Ubuntu 20.04 LTS), a test node will sync at approximately 13 blocks per second. If there are a million blocks, it will take approximately 21 hours per million blocks to catch up.

To get a live estimation:

  • Check the increase in block height over a 30s period on your node and divide by 30 [blocks/sec].

  • Check the difference in height on the explorer compared to the node, to find the number of blocks needed to catch up [qty of blocks]

[qty of blocks] / [blocks/sec] = time remaining in seconds /3600 for time in hours

Checking sync status​

You can check the status of your node sync by running the following command: As root user

cudos-noded status 2>&1 | jq -M
how do i know when my node is synced?

Your node is fully synced when you see: "catching_up: false" and the latest "block height" matches the network Testnet Explorer or Mainnet Explorer

synced-node

Fully synced​

In the above example,"catching_up": false and "latest_block_time" is a few seconds before current time. This indicates that the node is fully up to date. We can also compare the "latest_block_height": "326283" with the CUDOS explorer for confirmation.

Syncing in progress​

If your node is still syncing: latest_block_height and latest_block_time are incrementing and you can see "catching_up": true.

Not Syncing​

If "latest_block_height": "0", your node is not syncing. Try to add another seed (refer to Manually adding new seeds)
