The "Linux" binaries listed on bitcoincore.org and other download sites are for x86 (32-bit) and x86_64 (64-bit) architectures. Raspberry Pi is an ARM-based architecture, so you need the ARM binary (32-bit if you have a 32-bit OS, 64-bit if you have a 64-bit OS; both are commonly used on Raspberry Pi).

A transaction itself doesn't have a storage structure for timestamp. So the transactions don't know when they're created. But, after bundling the transactions into a block and while solving the hash problem to solve the block, the miner inserts timestamp at the block level.

For example consider a credit card--people charge to the card for 30 days and then pay the card once from their bank account at ...

Think about 250 GB hard disk just 5 years earlier (blockchain size would have been around 200 GB then), it used to be so costly. I believe by time goes by, rate ...

There is a risk that the blockchain will continue to grow too quickly and become unwieldy, yes. However, if technology improvements continue at their current pace for several decades, and Bitcoin survives the intermediate turmoil, it will eventually start to get easier to run a node again. "Chopping off some portion" significantly changes the ...
