All these confirmations and transactions are time-stamped on the blockchain, making them irreversible and impossible to tamper with.

Users are able to navigate the blockchain for bitcoin and review transactions in terms of quantity only. However, Bitcoin s blockchain keeps a record (on an immutable ledger) of all the transactions that occurred since its launch in 2009. Both transactions go into the unconfirmed pool of transactions.
