Understanding the input size for P2PKH transactions on Ethereum
The public-fold-based cryptocurrency of Ethereum, P2PKH (fairly good privacy) enables users to carry out secure transactions without revealing their private keys. However, the input variable of a P2PKH transaction can be confused for newcomers and experienced developers.
Input variable: What does it mean?
The input variable of a P2PKH transaction refers to the length or the number of bytes of the input data used in the transaction. This information is crucial to determine whether a certain input variable can be realized or not.
Standard miner implementation: Pay-to-Pubkey
In order to understand why the standard miner implementation is used in Ethereum Pay-to-Pubkey, we have to immerse ourselves with the details of processing transactions in the network.
A P2PKH transaction consists of two inputs:
- Push value : The input value used in the transaction (in bytes).
- Signature : A cryptographic signature (using a private key), which proves the identity of the sender and confirms that they control the associated public key.
The miner implementation uses Push + SIG + Push + button = 1 + 72 + 1 + 61, which is translated:
- Push value: 1 byte
- Signature length: 72 bytes (assuming a SHA 256-based hash function)
- Public key length: 61 bytes (again assuming a SHA 256-based hash function)
Why pay-to-pubkey?
The use of pay-to-pubkey enables miner implementation to efficiently check and process transactions. Here is the reason:
* Hash function : The SHA-256-hash function is used to create a clear input value, which is then signed by the sender.
* Check
: The signature checks the identity of the sender and ensures that the public key connected to the transaction is actually controlled by the sender.
What about the standard -Miner implementation?
The standard miner implementation uses Pay-to-Pubkey because it enables efficient and scalable processing of transactions. By using a single input value (push + Sig), the miner can check the signature and extract the public key in a single company, which reduces the computing effort.
Diploma
In summary, the understanding of the input size of P2PKH transactions for the design and implementation of safe and efficient Ethereum nodes is of crucial importance. The standard miner implementation uses Pay-to-Pubkey to optimize processing efficiency. This can lead to different input advisors, depending on the specific application or the implementation used.
Note that this information can change when new versions of Ethereum are published and updated implementations can change the behavior of the miner. For developers and users who want to create safe and scalable nodes, it is crucial to remain up to date with the latest developments in order to ensure optimal performance and security in the Ethereum network.
