The Eternal Konundrum: To prevent falsification of nodes in Ethereum
As long as the Ethereum exists, the decentralized nature of the blockchain has caused a fundamental concern about preventing malicious nodes from the consensus process and claiming to be set as their own work. In this article, we immerse yourself in the mechanics behind the relay process and discover why another node cannot easily solve the solution and claim to be your own.
The relay process: decentralized proof of work
If a new block is added to the Ethereum blockchain, this is not just a simple summary of transactions. Instead, a significant computing power is needed to enforce its validity. This is how the relay process works:
1
Verification : Each node checks the new block by checking and ensuring that all transactions are valid.
- Hash Creation : The controlled block is then divided into smaller blocks, called “hashes”, which contains a unique identifier for each transaction within the block.
- Transaction Control
: All transactions within the block are proven to ensure that it is valid and complies with Ethereum rules.
- Block reorganization : If the block has more than 2^64 (16 exabyte) transactions, its entire contents are converted into smaller blocks, called “headers”.
- Checking Headers : Each header is then divided into smaller blocks, which are further organized into a single block called.
- Create hash :
- Verification: Check that each block has at least 32 unique transactions and that all headers meet the rules of Ethereum.
- Create hash: Create a Sha-256 hash from the entire block.
Problem for falsifying node
Now, let’s deal with why another node can’t easily solve the solution and we claim to be your own work. Here are some key reasons:
- Random number generation : Nodes generate random numbers for hashs during the hash creation process. This ensures that no node can predict the results of every block.
- It is impossible for calculation : Creating a valid blockchain requires a huge amount of calculation performance. Even with modern hardware, solving complex mathematical problems, such as Ethereum Work-on Work (POW) algorithm, would be impossible for most nodes in terms of calculation.
- Block reorganization : If a block is divided into smaller blocks during the relay process, each node must be separated and reorganized separately. This makes it extremely difficult for the malicious node to have a convincing solution that can deceive multiple nodes at a time.
Result: decentralized control process
In summary, the decentralized nature of Ethereum, combining the random number and calculation of complex mathematical problems, ensures that only legitimate nodes are married to the blockchain. Any experiment of another node to create a solution can be detected by various tools:
1.
- Hash Control : Each hash is justified separately at each node, making it impossible for a single node to be impossible.
- Detection of block reorganization
: If the blocks are divided during reorganization, this process makes it difficult for the malicious node to create a convincing solution.
In summary, the design of the Ethereum ensures that the consensus process is safe and resistant to counterfeiting the node. Combined with the decentralized nature of the blockchain and the ignorance of complex mathematical problems, it provides a robust security mechanism that protects the integrity of the network.
