How is that long string of characters called a transaction hash (TxID) actually generated?
Bitcoin uses SHA-256 to calculate block hashes and transaction IDs—and runs it twice (double SHA-256).
To check a transfer, search for its transaction hash in a block explorer. It’s much more reliable than relying on a screenshot someone else posted.
Mining $BTC is essentially repeatedly calculating SHA-256 hashes to find a result that meets the difficulty requirement. The current price is 82586.
