I want to run a stake pool for fun and learning purposes and not for profit. What are the minimum hardware requirement for that? I have an old laptop with 2Gig RAM and 256Gig storage.
As per this documentation, https://docs.cardano.org/en/latest/getting-started/stake-pool-operators/creating-a-stake-pool.html,
in terms of hardware, you should ensure you have the following:
8 GB of RAM
24 GB of hard disk space
a good network connection and about 1 GB of bandwidth per hour
a public IP4 address
Note that processor speed is not a significant factor for running a stake pool.
