Ethereum: Does P2PKH substitute P2PK in any circumstances? Why?

Ethereum’s P2SH VS P2PK: Comparative Analysis

The Ethereum network, developed by Vitalik Buterin, has been pioneer in Blockchain technology since its inception in 2014. One of the key features of Ethereum is its use of cryptographic primitives based on public keys, including private key (public key) and public key hash (P2PKH). In this article, we will enter into the relationship between P2SH (pays for a sand) and P2PK in Ethereum and explore why P2PKH may not necessarily be replaced by P2PK.

What is P2SH and P2PK?

Both P2SH and P2PK are cryptographic primitives based on public keys used to secure transactions on the Ethereum network. Here’s a short review:

* P2PK : This is one of two primary types of pairs of key used in Ethereum, along with P2SH. In P2PK, a private key (public key) and the appropriate hash public key are stored on the client side, allowing users to send and receive funds without discovering their personal identity.

* P2SH : This is a P2PK variant using a separate “script” layer to confirm transactions. P2SH allows more transactions per entrance (ie paying per secretion), which makes it more appropriate for micro -payment and other cases of use in which the sender does not know what he receives in return.

Why is there P2PKH?

You may be wondering why Ethereum developed a separate type of pair of keys, even if P2SH exists. There are several reasons:

• Scalability : Although P2SH can handle more transactions per entrance, it requires additional network overheads to support this feature.

• Security

  : By maintaining two different pairs of keys (P2PK and P2SH), Ethereum developers aimed to improve overall safety by reducing the risk of compromise.

Does P2PKH replace P2PK?

In most cases, no, P2PKH does not replace the P2PK directly in any circumstances. While both species share similar functionality, they serve for different purposes:

• P2PK : This is a primary cryptographic primitive primitive primitive that is used to send and receive funds to Ethereum.

• P2SH : This variant uses a script layer to confirm transactions, which makes it more appropriate for certain cases of use such as microplje.

Why could P2PKH be useful?

Although P2PKH does not replace directly P2PK, it could potentially have some benefit:

* I improved security

: Having separate keys pairs, Ethereum developers aimed at reducing the risk of compromise in certain scenarios.

* Scalability : Additional overhead costs needed for P2SH can be acceptable if other cases of use online can compensate for it.

Conclusion

Although P2PKH exists and serves the purpose, it does not replace directly by P2PK in any circumstances. Instead, it represents an alternative approach to securing the Ethereum network transactions, primarily aimed at improving scalability and security.

As the Ethereum ecosystem continues to develop, developers are likely to explore new cryptographic primitives and innovations to improve the functionality of the network.
