Ethereum Classic (ETC) is a very smart blockchain digital asset. ETC has a well developed blockchain technology that makes it one of the top cryptocurrencies. For example, Bitcoin is like an old Nokia button mobile, which does few things very well. ETC wants to make sure that their technology is better than everyone, so they want to improve their security through Uncle Blocks.
Uncle Block is basically a block which is examined as an stale block in Bitcoin blockchain technology. It is not on the extended chain, it is a substitute block at the similar height as of its parent block. Ethereum Classic uses a list of Uncles when the miners mine a block. This creates two benefits; Firstly, it lessens centralization motive, however, it still rewards the miners that create stale blocks accordingly not being a portion of a big pool. Secondly, it raises the security of the chain by enhancing the quantity of work on the chief chain which is done in form of Uncles. Ethereum classic tweeted:
The scalability demands to have larger block sizes and compact block formation times. But unluckily, that damages the potential of blockchain technology to rapidly upgrade their system. If miners don’t upgrade copies of blockchains, it makes it easy to carry of 50% attacks because the mining resources become useless. Moreover, the expired copies do not stop the attackers from attacking the block because the attackers make their own attack chains instead of the new original blocks. So for Ethereum Classic it is important to have Uncle blocks for security because ETC has forty times less block formation time than bitcoin.
The Greedy Heaviest recognized GHOST protocol which was dicovered by Yonatan Sompolinsky and Aviv Zohar in 2013. This permits larger block sizes and compact block formation time. GHOST blockchain protocol allows lost blocks to enhance security. Using this technology, about 50% attacks must exceed the attempt to form the original chain and also form the losing blocks.
Ethereum Classic (ETC) executes a variant of GHOST protocol. The miners get more advantages for adding losing block headers in leading blocks. The composers of those losing blocks get the identical advantage. The leading chain is described as the heaviest chain such that losing blocks joins to the weight. The heaviest chain might not be the largest chain but due to victorious and losing blocks divide same ancestor blocks. Losing blocks are mentioned as Uncles. Almost two Uncle Block headers can be added in any block.
Lets consider that ETC network has a total number of genuine resources F. We can say that here, F is the number of mining resources that are not attacking the system. Suppose that ultimate network issues effect the productive amount of genuine mining resources to debase it to A. In such situation, two Uncle Block headers will probably be added in every original block. Thus, 50% attacks would have to copy the work of forming three blocks for each single original block so it can form a heavier chain.
Assume that the aim is to carry the difficulty of 50% attacks even during the occurrence of maximum network issues. Considering the extreme amount of uncle block headers. Ethereum Classic will maintain its security against 50% attacks unless it does not lose ‘two third’ of its honest mining resources.
This shows us that even the situation of ETC network is critical, Uncle blocks will help secure the ETC system. In such a condition, 50% attacks are difficult to happen if the Uncle blocks are fully utilized and the honest mining resources do not debase by more than 65%. Ethereum Classic with this innovation in security will surely help it grow more and will increase its adoption around the world.
