How new blocks are distributed in Ethereum: A step by step explanation
When a new block is created in the Ethereum block chain, it is not just about being added to the list of existing blocks. In fact, it requires a complex process that involves severe steps and controls. Here is a detailed explanation of how a new block is distributed in Ethereum:
The creation process
A new block is created when a miner solves a complex mathematical puzzle, known as a “hash function”, using the processing power of your computer. This puzzle is designed to be difficult to solve, ensuring that only legitimate transactions can create a new block.
Once the miner has solved the puzzle and created a new block, they transmitted it to the Ethereum Network through a special message called “Block hash”.
Verification process
To guarantee the integrity of the block chain, the use of the Ethereum network is a validation process. This implies the severe verification of the key aspects of the new block:
- Validation of transactions
: The new block is verified verifying that all transactions in the block are valid and have not been previously included in another block of the chain.
- Verification of block headers : The block header, which includes information such as the block number, the gas limit and the Nance (a single identifier), must be formatted correctly and contain a sequence of hexadecimal numbers.
- TRANSACTION COUNTING VERUATION : Each transaction in the block must have an increased counter, ensuring that the transactions are not reproduced or manipulated.
- Gas limit validation : The total amount of gas available for the new block must be sufficient to process all transactions.
If these verifications pass, the miner block is accepted in the Ethereum network and adds to the block chain as a “block” or “separate transaction”.
Announcing the new block
Yes you’re right; The newly created block does not need to announce its existence to nearby nodes. This is known as “transmission.” This is how it works:
- Block headers are transmitted : Each transaction in the new block is included in a special data structure called “block header”, which contains the information mentioned above.
- Discovery of nodes : nearby nodes in the Ethereum Network, as they executed by the Ethereum Virtual Machine (EVM), use their built -in database or other mechanisms to discover and store copies of these block headers.
- Node verification : When a node receives a new block header, it verifies that the information coincides with its local copy comparing the hashes of the blocks, the transaction counts, the gas limits and other details.
If all verifications change and a node finances an exact coincidence for the new block, they can store a reference to the block in its database. This allows the nodes to verify the authenticity of any sub -account transaction that includes this block as part of its chain.
How the nodes verify the new block
Once a node has received a new block header and verified its content, it is reading to start validating the sub -assembly blocks on the network. Here are some key steps involved in the verification of the new block:
- Validation of transactions : The node verifies that each transaction included in the new block is valid and follows the Ethereum rules to add transactions to the block chain.
- Comparison of block headers
: The node compares its local copy of the block header with the new block header received from other nodes, ensuring that all the information coincides.
- Validation of the gas limit : The node verifies that the total amount of gas available for the following blocks of the chain is sufficient to process any transaction.
- HASH Functions Verification : The Node verifies that the new block hash coincides with the expected value, ensuring that the puzzle will be resolved correctly.
