Can someone explain how these privacy protocols actually work?

Greetings! New to crypto privacy tech. Can someone explain how these privacy protocols actually work? Most explanations I find are too technical. Looking for practical understanding.

Greetings! Let me break it down simply. Think of Firo transactions like this: imagine a huge bucket filled with thousands of identical-looking coins, all different values but you can't tell which is which. When you spend, you're pulling coins from this bucket, but nobody watching can tell which specific coins you took because they all look the same. That's the anonymity set - currently up to 65,000 transactions in one set. The Lelantus Spark protocol uses zero-knowledge proofs, which basically means you can prove you own coins without revealing which ones. It's like proving you're over 21 without showing your exact birthdate. The "burn and redeem" model destroys your old coins and gives you fresh ones with no history. Simple as that. No trusted setup means no backdoors. Been using it for 8 months - works smoothly, transactions confirm quickly, and privacy is real. Way better than I expected!
