Here is an article on the two methods of multi-signature transactions in Ethereum and their differences:

Multi-Signature Transactions: Comparison

In the world of cryptocurrencies, multi-signature transactions have emerged as a safe and reliable way to conduct financial transactions. Two popular methods for achieving this security are “pay to pub key hash” (P2PH) and “pay to script hash”. In this article, we will delve into the details of each method, highlighting their strengths and weaknesses.

Pay to Pub Key Hash (P2PH)

The first multi-signature transaction method is pay-to-pub-key-hash, commonly referred to as P2PH. This approach involves creating a unique public key hash from multiple private keys, which are then used to spend cryptocurrency.

Here’s how it works:

• The user creates a new wallet and stores a list of his private keys.

• They create a transaction with a certain amount of cryptocurrency (eg 10 ETH).

• For each recipient, it adds its private key as an input parameter in the transaction.

• The transaction is then broadcast to the network, which includes a hash of the user’s wallet’s public key.

Pay to Script Hash

Another multi-signature transaction method is Pay to Script Hash (P2S). This approach involves creating a unique script from multiple private keys. and its use to spend cryptocurrency.

Here’s how it works:

• The user creates a new wallet and stores a list of their private keys.

• They create a transaction with a certain amount of cryptocurrency (e.g. 10 ETH).

• For each recipient, they add their private key as input parameter in the transaction.

• The script is created by combining the hashed public keys of the user’s wallet and the private key of each recipient.

Differences between P2PH and P2S

While both methods aim to achieve multi-signature security, there are significant differences between them:

• Input Parameters

  

  : In P2PH, input parameters (private keys) must be specified for each recipient. In contrast, in P2S, input parameters can be any type of data (e.g., hash scripts).

• Script complexity: P2S requires a more complex script to build because it needs to include all private keys and public key hashes.

• Security : Both methods are secure, but P2PH has some inherent advantages. For example, if a single recipient’s private key is compromised, the damage is limited to that particular transaction. Conversely, if multiple recipients’ private keys are compromised, an attacker can spend cryptocurrency from of all transactions.

Conclusion

In conclusion, multi-signature transactions offer an attractive solution for secure and reliable financial transactions on Bitcoin and Ethereum. While P2PH provides a simpler approach with inherent security advantages, P2S offers greater flexibility and customization. How does the use of multi-signature transactions As more signatures continue to grow, it is important to consider the strengths and weaknesses of each method to ensure optimal security and performance.
