In Ethereum, we often come across some very strange terms. Very few people seem to be aware of what these uncles are and represent. These have nothing to do with family ties in the traditional sense. Instead, an uncle is a referred to as a network block which would normally be considered an orphan. Bitcoin users are well aware of how some blocks are orphaned because they were mined just after someone found the correct block header.
Uncles work in a similar way, but there is a major difference. Miners on the Ethereum network are incentivized to include a number of uncles every time a block is mined. This is another example of how Ethereum is very different from Bitcoin. In Bitcoin mining, an uncle would yield nothing. Some people may wonder why the Ethereum network is set up in such a way they would incentivize miners to include uncles.
There are two main reasons for this. First of all, it decreases decentralization in Ethereum mining.

Everything is perceived from the perspective of the current block being mined on the blockchain. This is the way most of these terms were created because of the importance of the main chain and the block being worked on right now. Let me know if any words remain unclear in the comment section. Naturally, the Ethereum blockchain consists of blocks. These blocks are produced by miners, and they also contain the identifying information from the previous block.
Any children blocks they may have had would be our uncles. In terms of cryptocurrency i. Stale meaning, they were late, they did not get included in the main chain, and the effort invested into creating these otherwise valid blocks except the fact they were late often goes unrewarded. In this article , he explains how uncles work in great detail, with various calculations regarding the different possible outcomes.
His goal? To improve the security of the network, and lower centralization risks. He performs calculations where one powerful mining pool is found in the midst of small ones. The hypothesis is that would-be attackers do not need to mine the stale blocks, they can just pick up from where they left off to generate their parallel chain, effectively gaining an upper hand over the main chain.
This is still rather unlikely because it requires a significant amount of hidden mining power to operate and is in itself a questionable decision in terms of profitability.

The evolution of the crypto ecosystem is bringing massive technological disruption in the industry. Blockchain enthusiasts are often intrigued by the number of terms coming up in the cryptoverse as a result of the upcoming technologies. During the mining process, miners attempt to generate new blocks. A miner successful in finding a new block is entitled to the reward. However, it is likely that two miners produce a block at the same time.
In this case, the block with the larger share of proof of work POW gets accepted into the blockchain. The other block is discarded from getting added to the blockchain and is termed as an orphan block; these blocks are essentially valid and verified but are orphaned due to delays in network propagation. Miners are paid incentives to include uncles every time a block is mined.
Uncles are added to the calculation of which block has the highest total proof of work backing it. For example. There are 5 blocks- A0, A1, A2, B1, and B2. Now, if C1 is added to the chain, B branch gets chosen as it is the heaviest because the inclusion of uncle C1 results in an additional block in the branch weight.

A year ago I was hired by Eth Dev Ltd through Coinspect to perform a security audit on the Ethereum design. One of our findings was that the uncle reward strategy in Ethereum was weird, and could lead to miners abusing the uncle rewards to almost triple the money supply. At that time I explained the flaw and suggested to limit the number of uncles to prevent an unbounded money supply function. Last week, and the night before a presentation of the RSK a.
Rootstock smart-contract platform, I decided to explore the problem a little more, and I found to my surprise that the uncle mining strategy theoretically works in Ethereum at very low thresholds, and therefore the current Ethereum consensus protocol is certainly not incentive compatible. Uncle mining strategy consist of forcing you own blocks into uncles blocks not in the best chain in order to earn uncle rewards while preventing your blocks from contributing to the block difficulty adjustments.
Uncle mining is a greedy strategy or even it can be considered dishonest , as the greedy miners get monetary compensations while providing less of the expected service to the network: uncle mining does contribute to securing the network due to GHOST weighting, but does not contribute to increasing the network transaction processing power.
Before publishing this post, I exchanged e-mails with Vitalik Buterin to check the math and make sure the problem exists. My duty now is to report it to the Ethereum community. The good news is that fixing it is easy, but the bad news is that it requires a hard-fork. The uncle mining problem is not exactly a security vulnerability, since no ether is stolen.
However, it can bee seen as an unfair advantage, a design flaw, and a risk to the stability of the network. Things can get complicated if the majority of miners engage in uncle mining without coordination.

Ethereum Stack Exchange is a question and answer site for users of Ethereum, the decentralized application platform and smart contract enabled blockchain. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. We have two calculated blocks, both of them have 2 uncles, but one block has 8. What have I missed? In the first example, there are two uncles, U1 and U2. The uncle number of U1 is , and the uncle number of U2 is The block number is and R is 5.
One block is the parent’s generation, the other one is the grandparent’s generation. For the second example, the uncles are in the same generation but the generation is further away three blocks lower , so the overall uncle reward is lower:. Sign up to join this community.

22/09/ · What are the uncles in Ethereum? Naturally, the Ethereum blockchain consists of blocks. These blocks are produced by miners, and they also contain the identifying information from the previous block. In Ethereum’s family tree, this previous block is considered to be the parent of the current heathmagic.deted Reading Time: 4 mins. 31/08/ · An uncle is a block that, in bitcoin, would be considered a stale block because it is not on the longest chain (it’s an alternative block at the same height as your parent). Ethereum incentivizes miners to include a list of uncles when they mine a block.
This limit restricts the total gas which can be spent by the transactions contained within each block. And theoretically, raising the limit enables the Ethereum network to process more transactions per second. Each block in a blockchain is formed from the one before it, also known as its parent block. When multiple blocks are produced from the same parent, only one becomes part of the blockchain permanently.
The other block produced but not included is known as a stale block. Stale blocks can be included into the chain as an uncle block or ommer block, the gender-neutral term. Ethereum rewards miners with a small block reward for producing uncle blocks in an effort to combat centralization. Uncle block rewards make mining on lesser hardware or mining outside of the largest mining pools more cost effective. A higher gas limit means more transactions per block.
More transactions means more data which means larger block sizes and a larger blockchain state which needs to be stored by miners and nodes. Overall, a higher gas limit means it costs more resources to run a node. This can reduce the total number of nodes on the Ethereum network. Furthermore, potentially less nodes and larger blocks can affect how fast blocks spread throughout the network.
