The Main Difference between Orphan Block and Uncles in Ethereum is that an Orphan block is a block that has no known parent, while an Uncle is a block that has a known parent but is not part of the main Ethereum blockchain.
Orphan blocks can occur when two miners produce blocks at roughly the same time, and each miner’s block references a different previous block. In this case, the blockchain forks and each fork has its own main chain.
NOTE: WARNING: Orphan blocks and uncles in Ethereum can be confusing concepts to understand. Orphan blocks are blocks that are included in the blockchain but are not part of the main chain, while uncles are blocks that were mined and accepted by the network but were not included in the main chain due to a lack of consensus. It is important to note that uncles receive a reward for their efforts, while orphan blocks do not. Understanding the differences between these two concepts is essential for anyone working with Ethereum or other cryptocurrency networks.
Eventually, one of the chains will become longer than the other, at which point it will be considered the main chain and the other chain will be considered an orphan chain.
Uncles, on the other hand, can occur when a miner produces a block that references a previous block that is not part of the main blockchain. In this case, the miner’s block is not added to the main blockchain, but it is added to a side chain called an uncle chain. Uncle chains are shorter than the main blockchain, but they are still valid chains.
When a new block is mined on the main blockchain, it can reference one or more uncles, which causes those uncles to be added to the main blockchain. This process helps to secure the Ethereum network by making it more difficult for an attacker to create a long chain of blocks.

Quorum is an enterprise-focused version of Ethereum. It’s a permissioned blockchain platform that’s ideal for building enterprise applications. Quorum is a fork of the Go Ethereum client, and it’s developed by JPMorgan Chase.
An uncle is a stale block—one that’s been created and subsequently abandoned by the network before it was incorporated into the main Ethereum blockchain. Uncles are caused by the forking of the Ethereum network and can earn a small reward for miners. While uncles are not part of the main blockchain, they are still verified by Ethereum nodes and can be viewed in any block explorer.
Vitalik Buterin is a Russian-Canadian programmer and writer primarily known for his work on Ethereum, an open source public blockchain platform. He is a co-founder of Ethereum and one of its lead developers. Buterin first became interested in blockchain and cryptocurrency technology in 2011 and he soon became involved in the Bitcoin community, co-founding Bitcoin Magazine in September 2011.
