Orphaned Blocks are unconfirmed blocks.

Technically, any cryptocurrency system is a unique and fundamentally new solution introduced over 10 years ago. Among the many different terms, there are such as Orphaned Block. Simply put, these are blocks that, for one reason or another, are not included in the blockchain chain. Miners do not receive the expected payment for these blocks.

Where do orphans come from?

The banal reason such blocks are formed is several miners' simultaneous broadcast of found blocks. That is, several competing versions are created. In this situation, the shorter chain is discarded.

Before 2015, this phenomenon was not uncommon. Parent blocks whose origin has not been confirmed or simply do not exist could have entered the network. However, the formation of such blocks became impossible after updates and the introduction of a new version of Bitcoin. This also ensured higher reliability and stability of the entire system.

Another reason for the appearance of such elements is that they are created by scammers who are trying to replace genuine blocks with their designs.
