Create and host Chainstate Snapshots

Host snapshots at reduced cost when spinning up new node.

Create Storj account

After creating an account on Storj DCS, you’ll need to setup the uplink cli.

Setup uplink CLI

The uplink cli is a tool similar to aws cli that allows creation of buckets and uploading/downloading snapshots directly from the 15,000+ storage nodes. We also have an aws s3 compatible api as an alternative.

Install uplink

Linux AMD64

For different uplink binaries see Download Uplink CLI

Create access grant and setup uplink

Creating an access token in the Storj web console



Click "Continue in CLI" after giving your access grant a name



Run uplink setup to start the credentials prompt

Enter a name for the credential (default is "main")

Copy your "API Key" from the web console to the uplink cli "Enter API key or Access grant" prompt



Copy your "Satellite Address" from the web console to the uplink cli "Satellite address" prompt



Enter a passphrase to complete the setup

Create bucket

Create a bucket called snapshots

Upload snapshots

Compress small files/directories to a single compressed file (e.g use tar).

Use uplink cp to upload your snapshot to Storj DCS. Scale parallelism to at most 2x your thread count (16 threads = 32 parallelism)

Create download access grant

For node operators in your community, you'll need to generate another access grant with limited permissions.

Create another access grant with the following limitations

1. Check only 'Download' (leave others deselected)
2. Select snapshots as the bucket from the dropdown



Select "Continue in Browser"

Copy the access grant in file. You'll use it later in the template below.



Adapt the Download blockchain snapshots template, changing <your_access_grant> fields to the Download-only access grant. The commands from the template can be published to your communities.
