Chain reorganization

A change to the accepted chain that replaces previously accepted blocks with another valid branch.

PLAIN-ENGLISH DEFINITION

In more detail

A reorg can make a transaction lose confirmations after you already saw it in a block. It may become pending again, or a conflicting transaction may take its place. This is one reason apps distinguish 'included' from more confidently settled, especially when only a few blocks have followed.

IN THE WILD

How you might use it

'The explorer said confirmed a minute ago.' A short reorg replaced that block, and the payment is waiting for inclusion again.
