They decide how to resolve a potential double spend. But a double spend is really when conflicting txs append to the blockchain. So validating blocks is the preventative measure.

During the validation process.
The successful miner will have validated transactions and in the case of a double spend where all conflicting transactions are still unconfirmed, the miner will have chosen one of them based on their own criteria such as fees, other associated unconfirmed transactions, and their fees. That is how a double spend is RESOLVED.
A double spend is PREVENTED when nodes validate blocks and ensure that there are no double spends present within the blockchain. If a double spend is detected, then the block is not appended to the user's blockchain and the double spend is prevented. This happens the same on all nodes across the network.

I call bullshit. Madeira never existed before Bitcoin. Heck they weren't even around to invent madeira cake.

Looks like it is warning you that it hasn't got the latest info yet and you're asking it to add a contact on top of an empty list... It is assuming that this is wrong (which it is) and avoiding the worse outcome where people start asking "I used to follow 100 people, now I follow no one?"

The timestamps on the blocks are written by the miner that built the block.
Computers suck at time, so the time of one machine may be minutes off another, also miners could be intentionally lying in the hopes of breaking or swaying something in the Bitcoin protocol.
Fortunately, this is all accounted for in the code. Timestamps are allowed a threshold of error when an active node sees it, so that reduces massive lies, and there is also a threshold, although more forgiving, applied when nodes are validating historical blocks during bootstrapping.
Also the difficulty adjustment algo in Bitcoin relies on the timestamps, but it relies on median averages instead of mean averages because that is less susceptible to biases.
Bitcoin has us covered.

My nostr experience is pretty fine, for social media, for zaps, for keeping a private spreadsheet via sheetstr, and for blogging.
I also don't see a wave of nostr devs getting frustrated with technical debt or bad design and quitting, heck I see interest growing.
Look out the other window friend.
