Changing block complexity on the Ethereum network
Ethereum, one of the most widely used blockchain platforms, is largely on the decentralized mining process. Miners compete to solve complex mathematical puzzles to confirm the transactions and create new blocks. However, changing the block after creating it is not as easy as it may seem.
In this article, we will go into the complexity of the Ethereum block change process and look at whether the miners can easily modify the block or have any restrictions.
Mining Process
When the miners discover a valid block on the Ethereum network, they usually submit it to the blockchain as the proposed changes. The Ethereum Community is then reviewed by the proposed changes using a unanimity mechanism called evidence of work (POW). Miners who think their solution is better than the original is stimulated to solve the dough and add the block to the block.
Modified block
Once the miners have added their solution, they should check whether it is right. They do this by solving another puzzle known as the “target hash”, which must be less or equal to 6000 times the Hash target of the previous block. If the solution is valid, the modified block is included in the next block.
Can miners modify the block?
Now let’s turn to the issue available: Can the miners modify the block after it is created? The answer is yes, but with a few warnings.
Ethereum has several transactions in each block that are combined and tested through Pow. When the miner finds a valid block, they do not only add new transactions to the existing block. Instead, they create a new block with modified transactions.
Modified block structure
Miners can modify blocks in several ways:
1
Inserting new transactions : Miners can place new transactions in the existing block by creating a new block and placing a modified transaction in it.
- Transaction Removal
: Miners can also remove transactions from an existing block by dealing with another dough that allows them to delete a particular transaction without affecting the entire block.
How does miners know if they can modify the block?
To determine if the miner can modify the block or not, they need to solve the target hash to make the proposed changes. However, there are limitations in this process:
1
Miners’ knowledge : Miner must have complete knowledge of the Ethereum network and all previous blocks to make sure their solution is valid.
2
Time limit : Miners have only limited time (known as the “slush period”) before the block is combined with other network blocks.
What happens if the miner can modify the block?
If the miners can successfully modify the block, they will be rewarded with a certain number of Ethereum markers known as “gas”. The gas border is determined by the Ethereum Virtual Machine (EVM) and is calculated based on the complexity of the dough to be resolved.
Conclusion
In conclusion, changing the block after creating it, Ethereum is not as easy as it might seem. Miners can modify the blocks, but they must have complete knowledge of the network and resolve the target hash of their proposed changes. The process involves creating a new block with modified transactions that require significant computing power.
While it is possible to modify the block, miners are usually limited by their knowledge and time constraints. It is worth noting that the Ethereum developer team has taken measures to prevent malicious modifications, such as the use of hinging and zero knowledge evidence.
When summing up, changing the complexity of changing blocks on the Ethereum network, it is difficult for miners to modify the block after it is created.
