Multisig Setup - Pruned Bitcoin Core on Computer vs. Dedicated Hardware

[AdamHurwitz]

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 [1].
• One non-security implication is the performance impact on the personal computer when running the pruned Bitcoin Core node.

No. Pruned nodes validates blocks the same way as non-pruned nodes which gives it the same security in that aspect. The key difference between pruned and non-pruned nodes is that the former cannot retrieve any data about the blocks beyond the pruned range, thus not allowing the user to import new addresses, query any information from then as well. Pruned nodes will discard unnecessary block data as it synchronizes and maintains it within the size limit which is defined by the user.

Bitcoin Core supports Multisig as well, but I assume you require a GUI which is why you're relying on another wallet.

Most of these "dedicated hardware" you are talking about are actually just software wrappers around Bitcoin Core, and Core by itself is arguably more secure than when you pair it with other software, because Core goes through an extensive code review process before each version is published while other software do not have these same procedures and thus are more susceptible to flaws.
