Background jobs

Blobscan requires BullMQ to run the following tasks in the background:

• DailyStatsCronJob - calculates metrics for the blobs, block and transactions charts.
• OverallStatsCronJob - calculates other metrics such as Total Tx Fees Saved, Total Blocks and Total Blobs.
• SwarmStampCronJob - updates TTL for Ethereum Swarm batches.

For more information, check out the @blobscan/jobs app.

The BullMQ queue is also used to upload blobs in parallel to different Storages.
