Ethereum: Where are P2SH Full Redeem Scripts Stored?

When a user spends their Ethereum, they essentially “unlock” their funds and make them available to others on the Ethereum network. However, the redemption scripts used for these transactions require some additional processing steps before they can be released back into circulation.

One of the most notable features of Ethereum’s scripting mechanism is its use of pay-to-script-hash/P2SH (Pay-to-Script-Hash) full redemption scripts. These scripts allow users to “redeem” their coins by solving a complex mathematical puzzle, and in return receive a certain amount of funds back in cash.

But where exactly are these P2SH full redemption scripts stored? The answer lies in the wallet management systems used by Ethereum users.

Where Do P2SH Full Redeem Scripts Live

P2SH full redemption scripts are typically stored in a user’s wallet, specifically in the “redeemed” section of their account. This section is usually located under a key called spent or script-amount.

The spent contents of a wallet are often grouped by script type and redemption amount. For example:

• Spent

  wallet: A collection of full-exploitation scripts used to spend Ethereum.

• Script-amount

  (in bytes): A separate section that stores the data of the withdrawal scripts in a specific format.

When a user “spends” their coins, their wallet is updated accordingly, and these redemption scripts are essentially “released back into circulation”. However, this process also requires some additional processing steps to verify the redemption and update the wallet’s internal state.

How ​​Wallet State is Updated

Ethereum’s wallet management system includes several key components:

• Wallet Storage: Ethereum stores user wallets in a decentralized manner using a combination of blockchain data structures (such as Merkle trees) and cryptographic hashes.

• Exploit Script Store: Scripts for fully exploiting P2SH are stored in the Exploited Wallet section, which is updated each time a transaction is made or spent.

To update a wallet state after a redemption, Ethereum performs the following steps:

• Verification: Checks the redemption data to ensure it matches the user’s intent.

• Exploit: Returns the funds back into circulation and updates the wallet’s internal state accordingly.

• Storage Updates: The wallet’s spent contents are updated within the wallet storage system.

Storing the Full Exploit Script: Security Considerations

While Ethereum’s P2SH full-redeem scripts provide a convenient way to spend coins, they also introduce some security considerations:

• Script Encryption: Scripts are encrypted using advanced cryptographic techniques (such as ECDSA) and hashed for secure storage.

• Wallet Hashing: Wallets use hashing algorithms (such as SHA-256) to securely store redemption data.

In Conclusion

The P2SH full-redeem scripts used in the Ethereum wallet management system provide a robust way to spend coins while also ensuring secure storage of redeemed data. Understanding how these scripts are stored and updated provides valuable insight into Ethereum’s underlying architecture and security mechanisms.
