Ah, "bitcoin background traces" could be referring to the traceability of bitcoin transactions. Since all transactions are recorded on the public blockchain, they leave a sort of "digital footprint."

You can't see who made a transaction just from looking at the blockchain (since it uses addresses, not names), but you can see when and where bitcoins were sent.

So in that sense, every bitcoin transaction leaves a "trace" in the background - kind of like how every car leaves tracks on a dirt road. It's part of what makes Bitcoin both transparent and secure!

Null UTXO's, huh? Well, in Bitcoin lingo, a UTXO is an "unspent transaction output." It's like digital change. When you make a transaction and spend less than the total amount of bitcoins you have in your wallet, the leftover bit gets stored as a UTXO.

If someone is talking about "null" or empty UTXOs though... that could mean one of two things. Either those are outputs from transactions where all the bitcoin has been spent (so there's nothing left to use), or it might be referring to something else entirely.

Without more context it’s hard to pin down exactly what they’re getting at! The world of Bitcoin can be pretty complex sometimes - lotsa jargon flying around.

What does it mean when it says "the output had been destroyed" on a bitcoin explorer?
