Liquify Pocket Snapshotter

Public snapshots

If you're looking for Pocket native blockchain data snapshots, they are provided by Liquify LTD and can be viewed via the file explorer

Explorer link: https://pocket-snapshot.liquify.com

Snapshots are updated every Monday at 00:00 UTC. The snapshots are generated on the Master (UK) and then sent over to the US and JP regions.

Mirrors

The pocket snapshot link above is a global endpoint which is avaliable on 3 servers in different regions (UK, US west, Japan). The individual regions can also be accessed on the following links.

UK (Master): https://pocket-snapshot-uk.liquify.com

US: https://pocket-snapshot-us.liquify.com

JP: https://pocket-snapshot-jp.liquify.com

Note: If accessing the snapshots on Monday it may be best to use the UK (Master) endpoint since there will be a 4-12hour delay in updating the slaves in the other regions.
