Ethereum: What happens if two miners disassemble the next block at the same time?
In the world of cryptocurrency removal, the process is as complicated and complex as it sounds. As described in our previous responses, several miners work together to solve a mathematical puzzle that is called the “Pow) algorithm. This puzzle requires considerable calculation power and energy. An important aspect of the POW algorithm is that it must be solved individually by each miner. However, what happens if two miners try to solve the same puzzle at the same time?
The answer is in the concept of time synchronization, which ensures that all the miners do their work at the same time.
How time synchronization works
In Ethereum and other cryptocurrencies, the miners use special hardware with a work evidence algorithm, which are called application specific circuits (ASIC) or graphic processing units (GPU). These devices are intended to quickly resolve complex mathematical equations. To achieve synchronization, several miners usually use a process that is called the “temple of time” or “synchronization of time”.
If a miner weakens the puzzle, it immediately calculates its block number with the current time stamp and the anterior hash value of the previous block. If two miners try to solve the same puzzle at the same time, the calculated block numbers are tight.
What happens when two miners find the next block at the same time?
In a hypothetical scenario, in which two miners find the next block at the same time, some things could happen:
- Duplication of the block : If two miners run POW algorithms simultaneously, they can generate identical code or data blocks. In this case, one of the miners should reject their double block and send it back to the network to ensure that only a valid block is added to the blockchain.
- Duplicate of transaction : The duplicated block may also contain contradictory transactions, which can be automatically dissolved by a validator (a node in the Ethereum network). Alternatively, the nodes could solve them manually.
- Block lock : If two miners find identical blocks at the same time, you should override each other with your own code or data.
important considerations
It is important to note that there are several factors that influence a double block and how to be treated:
* Network plating : The time when the miners have to solve the puzzle has an impact on the probability that a duplicate is found.
* Pow -grad Dewivel
: With the increase in the difficulty level of POW difficulty, the chances of two simultaneous attempts leading to a double decrease.
* Hash collisions : If two miners try to solve the same puzzle at the same time, you can enter a state known as “hash collision” in which your code or data become identical.
In summary, theoretically it is possible for two miners to find the next block at the same time, the probability of this event in practice is extremely low. The robust mechanism of the time temple of the network and the difficulty level of POW difficulty works together to prevent the addition of double blockchain blocks.
