No, orphan blocks are not created only when an attack occurs on the blockchain. Orphan blocks can be created for a variety of reasons, including:

-When two miners produce blocks at roughly the same time
-If a miner produces a block that is not valid according to the blockchain’s consensus rules
-If a miner produces a block that is valid but is not accepted by the network due to network latency

Orphan blocks can occur during normal operation of a blockchain and are not necessarily indicative of an attack.

Q: What are orphan blocks in blockchain?

A: Orphan blocks are blocks that are not part of the main blockchain. They can occur when two miners produce blocks at roughly the same time, or when a miner produces a block that is not accepted by the network.

Q: How is an orphan block created?

A: There is no definitive answer to this question, as the process by which orphan blocks are created can vary depending on the specifics of the blockchain protocol in question. However, in general, an orphan block is created when a node in the network receives a block that is not part of the longest valid chain of blocks. This can happen, for example, if two different nodes produce a block at roughly the same time, and each node broadcasts its block to the network before receiving the other node’s block. In this case, each node would end up with a different version of the blockchain, with one node’s blockchain containing an orphan block.

Q: Under what circumstances would a node receive an orphan block?

A: There are a few reasons why a node might receive an orphan block:

1) If the node is configured to accept blocks only from a specific set of peers, and it receives a block from a peer that is not in that set, it will consider the block to be an orphan.

2) If the node is not fully synchronized with the blockchain, it may receive a block that is not in its current longest chain. In this case, the node will consider the block to be an orphan.

3) If the node receives a block that contains invalid transactions, it will consider the block to be an orphan.

Q: How common are orphan blocks?

A: There is no definitive answer to this question since it can vary greatly depending on the particular blockchain and mining protocol being used. However, it is generally agreed that orphan blocks are not all that common and typically account for a very small percentage of all blocks mined.
