A block whose parent is not available to the client. Often falsely used for [stale-block].
What happens to rejected transactions ( i.e double spend or invalid transactions)?
Do they get put in an orphaned block or not get put into any block at all?
Is there a webpage showing some of the latest orphaned blocks?
What will happen if i change the checkpoint data from bitcoin source code and try to synchronice with blockchain?
What are the factors affecting the rate of orphan blocks? The one I can think of is network latency, the higher it is, the higher the rate of orphan blocks. Any other suggestions?
Is there a visualisation tool for discarded block chains in Bitcoin?
Tie Breaker to reduce orphaned chains?
An orphan does not have parents. On the other hand an orphaned block has a parent but no children. So shouldn't it be called barren rather than orphan?
Can there be stale blocks in "header first" implementation?
Block orphaned by same miner?
Just noticed 2 conflicting blocks by the same pool. One of the blocks was naturally orphaned, but why would the same pool broadcast 2 such blocks? Does it happen often?
How can pool operators reduce the number of orphaned blocks that they mine?
How often do forks occur in the block chain? I'm interested in the small, one block forks that happen when two miners create a block at the similar time.
