Orphan Block Definition
An orphan block, also known as a detached block, is a block that is not included in the blockchain network’s final consensus because another block with the same block height has been added to the chain. This usually happens when two miners solve a block at nearly the same time, causing a temporary fork in the network.
Orphan Block Key Points
- An orphan block is a valid block but is not part of the main blockchain.
- It occurs when two miners produce blocks at similar times.
- Orphan blocks are not rewarded with block rewards.
- They are a natural part of the blockchain process and are not necessarily indicative of any issues within the network.
What is an Orphan Block?
An orphan block is a block that has been verified and is technically correct, but is not included in the main blockchain. This happens when two miners solve a block at the same time, creating two potential paths for the blockchain to continue. The network will eventually choose one path, and the blocks on the other path become orphan blocks.
Why does an Orphan Block occur?
Orphan blocks occur due to the decentralized nature of the blockchain. When two miners solve a block at the same time, they will both broadcast their solution to the network. Depending on which solution reaches the majority of nodes first, one of these blocks will be added to the blockchain, and the other will become an orphan block.
Where does an Orphan Block fit in the Blockchain?
While an orphan block is technically part of the blockchain, it is not included in the main chain. Instead, it exists outside of the main chain. Even though it is not part of the main chain, it is still stored in the blockchain network’s history.
When does an Orphan Block occur?
An orphan block can occur at any time. It is most likely to occur when the network’s hash rate is high, causing blocks to be solved more quickly. This increases the chances of two miners solving a block at the same time.
How is an Orphan Block resolved?
The blockchain network resolves an orphan block by continuing to add new blocks to the chain. When a new block is added, it chooses the longest chain of blocks to add to. This means that the chain with the orphan block is left behind, and the orphan block is not included in the main chain. This process is known as the blockchain’s “consensus mechanism”.
