The secret of the confirmation of the Ethereum block: can there be an unreas off, the rest?
Ethereum, like most blockchain networks, depends on the consent mechanisms to confirm the transactions received and add new blocks to the book. The most important aspect of this approval process is the calculation of the block, which determines whether the network accepts the block or waste. However, when it comes to individual inappropriate operations (sessions) in a valid block, the rules can be more nuanced.
In the current Ethereum consent algorithm, called POW (POW), the approval process is designed to ensure that all circuits blocks are connected through many cryptographic puzzles. To prevent attacks and maintain the integrity of the network, the POW protocol requires that at least one block should have a valid and detailed bag.
When a mining (individual or group) detects a block whose operation is not correct, they are essentially “collected” by previous blocks without applying correctly. In this scenario, Sit can accept the net as part of the new block, even if it is not the only operation valid in that block.
Problem: an incorrect operation
To understand why an improper operation may not get rid of the entire valid block, we immerse yourself more deeply in the characteristics of the Ethereum bag. The function of the bag used by bow prisonality is the type of encrypted algorithm called “Sha-256” (algorithm of security bags 256). This function takes the contents of the block as input and creates a digital imprint or unique “bag” that is a connection between the blocks.
In the block sitting, the calculation of the bag includes different components. For example, when the validity of the block occur, miners use a combination of these factors to calculate the bag:
1
- Proof : a series of counting puzzles that cover the solution of cryptographic challenges.
- Coincidence : Additional variables such as TimesTamp and seed value.
When mining is determined in the improper operation in a valid block, it can modify it or completely modify the operation without affecting the overall stock exchange. That’s why:
* Replacement of the blocking of the
block: the unit header remains unchanged, which guarantees that the subsequent mining will however confirm the block using the same conditions.
* Unique tests and coincidence : even if an unrealized operation is removed or replaced, other lock operations remain valid due to their calculation puzzles. This means that the network cannot be “resolved” by any operation.
consequences of incredible unreas off*transactions
While an incorrect operation may not directly damage the overall integrity of the network, it can cause:
* The rewriting of the block : the mountains can rewrite or modify the contents of the block to accommodate sit, which can change the state of the blockchain and have unexpected consequences.
* Increases vulnerability : if more mining discover seats inside the valid blocks, it can create an “attack surface” to allow to exploit the harmful characters.
The future future of Ethereum
Ethereum creators continue to improve the consent mechanism to avoid these scenarios. Some possible solutions include:
* Test of the stake (POS) : instead of relying exclusively on the calculation power, mining could be encouraged by a “actions package” or other maintenance award.
* Delegated test of the episode (DPO) : the mountains should transfer their participation to a member of the network (like a node) instead of competing directly.
In conclusion, although some non -valid operations may not be awakened by all valid blocks, they may still have significant consequences.
