Let’s talk about hash functions.
Bitcoin uses SHA-256 to calculate block hashes and transaction IDs, and applies it twice in succession (double SHA-256).
One thing many people overlook: hashing is not encryption. Encrypted data can be recovered with a key, but hashing is one-way—you can’t get back the original content from the hash value.
To look up a transfer, search for its transaction hash in a block explorer. That’s much more reliable than relying on screenshots someone else posted.
Mining $BTC is essentially just repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement.
