Are there security implications of running a pruned Bitcoin Core node on a personal computer vs. a full Bitcoin Core node on a dedicated hardware device (i.e. Raspberry Pie with Umbrel, myNode, nodl, and etc.)?

  • The intended use case for the Bitcoin Core node is integration with a multisig wallet such as Specter, Electrum, and etc.

  • This scenario presumes the personal computer is configured to run Bitcoin Core through Tor/VPN (That do not save/collect logs) as in the Specter desktop 1-click setup. enter image description here

  • One non-security implication is the performance impact on the personal computer when running the pruned Bitcoin Core node.

Both a full Bitcoin and pruned node can be run from Bitcoin Core with the same level of security.

Pruned nodes have the following differences:

  • Does not keep the full blockchain on disk
  • Size limit is defined by the user
  • Will discard unnecessary block data as it synchronizes

As a user on the Bitcoin Talk forum explains, most "dedicated hardware" Bitcoin Nodes are software wrappers around Bitcoin Core which may be less secure than running Bitcoin Core directly.
