Ethereum: How does a pool know work has been done
How the pools check the work via Ethereum
If several nodes agree on the state of the main register in a blockchain network, it is important that not all nodes have verified that they do not copy and do not instead. This guarantees the integrity and reliability of the blockchain. However, a general misunderstanding is the way the pools check work in Ethereum.
In order to understand this, we immerse you in the bases of what is happening when the nodes agree on the state of the main book in an Ethereum network with a salgorithm of consensus by proof of work (POW).
Proof of work: energy -based consensus
In a POW -based system, nodes are competing to solve a complex mathematical problem. This process requires considerable calculation power and energy consumption. When a node finds a valid solution for the puzzle, it sends the status of the main register as “confirmed” to its local network.
However, if someone was trying to hold back or manipulate certain data without being discovered by other nodes (an “solution to solution”), he would have an advantage over honest validators. Indeed, their malicious actions could remain unnoticed until the majority of nodes check again and believe that the data have been manipulated.
How the pools check the work via Ethereum
In this context, a pool refers to a group of nodes or minors who work together to validate transactions and create the blockchain. If a node in the pool finds a valid solution for the mathematical puzzle (that is to say H. it accepts the state of the main register), it sends its results.
Here is what is happening next:
- Check : The solution is verified by other nodes of the pool which check the validity of the solution with special software.
- Propagation of the chain : If a node finds a valid solution, it updates the blockchain by sending the modification to all the other nodes of the network.
- Konse update : Each node checks the updated state and returns all the necessary modifications to the pool.
Ensure integrity
In order to prevent the retention of solutions, the pools must be interpreted taking into account security. Certain important characteristics of the algorithm of evidence of evidence of Ethereum are:
* Multi-Signature
: Pools often use a multi-situ configuration in which several node control solutions before being able to spread to other nodes.
* Verification on a network scale
: The revision takes place throughout the network, which makes it more difficult for malicious actors to manipulate data without being recognized.
Hold the attenuation solution
Although the Ethereum -based Pow -based system is always possible, pools can reduce this risk if solutions are always possible.
- Use a secure multi-signs configuration : Pools often use robust multi-sigs arrangements to prevent individual nodes from manipulating the solution.
- Implementation of the node check : regular updates and safety audits guarantee that each node is carefully checked before participating in the consensus process.
Diploma
In summary, the pools on Ethereum check the work by combining:
- Multi-Signature Configuration
- Network scale review
- Secure software updates
In order to prevent solutions retirement attacks, pools with robust security features and regular audits must be interpreted to ensure that all nodes have checked the state of the school.
