Ethereum: Semantic sequence number
As a developer working with Ethereum, it is important to understand the importance of sequences in the blockchain. In this article, we will dive into the sequence number semantics in version 1.
What are the order numbers?
The order numbers are unique identifiers assigned to each transaction on the Ethereum block. They allow effectively monitoring and controlling transactions in the block.
Version transactions: Semantic sequence number
Versions (V1) sequence number plays a crucial role in determining their sequence in the block. Here’s how it works:
- Blockchain is added a new deal.
- The deal is calculated and compared to the mixture of the previous transaction on the same block.
- If Hasler matches, the transaction is attached to the end of the block as a new block.
- If the hashes does not match, the previous transaction is replaced by the current.
In this process, the number of sequence of each transaction is used to determine its position in the block. The latest transaction has the highest order number (1), followed by the second recent transaction (2), etc.
Step -by -Step Procedure Example
Let’s say we have two transactions:
Deal A:
`'
0x000000000000000000000000000000000000
'
Transaction b:
'
0x000000000000001111111111111
` ‘
In this example, the transaction B has a higher order number (2) that the transaction A. Thus the transaction B is attached to the end of the block as a new block.
Semantic sequence number in transactions v1
The semantics of the order number described above are characteristic of version 1. In subsequent versions of Ethereum, such as in version 2 (V2), the behavioral behavior has changed.
The sequence number is used differently in V2 transactions:
- The transaction hash and the sequence number is combined to form an index based on the “number of blocks”.
- This index allows a more efficient command block, but it also introduces extra complexity.
Conclusion
Understanding the sequence number semantics 1. Version transactions is essential for working with Ethereum. When entering the order numbers are used to determine the order of the transaction, developers can optimize their code and create an effective application in the blockchain.
