Understanding Bitcoin: Why WalletprocessBT finalizes PSBT but does not return HEX to transaction
As you use the popular ProcessSBT portfolio to finalize the binary tree on the Payment script (PSBT) and add the BIP32 way. Production, you are right that this command returns a finalized PSBT. However, when it adds a new derivative path to an already signed and finalized PSBT, it does not return directly to the transaction.
In Bitcoin, the hash of each transaction is represented as a 64-byth hexadecimal string. When it adds a new derivative path to PSBT, the ProcessSBT portfolio generates this new hexadecimal performance of a transaction hash. This is done by using the method bip32.reivation and then hashs of binary data obtained.
Here’s what happens step by step:
- The portfolio portfolio process signs the input transaction with its private key.
- It creates a binary tree on the payment script (PSBT) from the signed transaction, which includes all the necessary information to design the production.
- The portfolio portfolio process adds a new derivative path to PSBT, using the ‘bip32.reivative’ method, specifying the path of a personalized derivative.
When you launch WalletprocessBT finalizes PSBT, it generates a finalized PSBT with the added way to the derivative. However, instead of returning directly to the transaction, it returns an object containing the finalized PSBT and other metadata.
Why don’t you return the transaction hexadecimal?
The portfolio process returns the finalized PSBT, as it is a binary format that is the tree of the script for payment. The BIP32.reition method uses an algorithm for hash (Sha-256, in this case) to generate the new path of derivative and the related value of the hash.
When you pass the finalized PSBT of the RPC command, such as Gettransction or print its contents usingDumpwallet, the portfolio processes will return the same object containing the finalized PSBTs and other metadata. However, the presentation of the sixteenth of the hash of the transaction does not return directly; Instead, it is built into this site.
An example of using the case:
Suppose you have a transaction signed with 30-byt input txid and vout(for example, txinmap= [0x1234, 0x5678])). The portfolio process signs the transaction using its private key:
bash
WalletprocessBT finalize TXID VOUT1 TXINMAP = 0x1234 0x5678 -Naith = MyDerivation
After completing this command, you receive a finalized PSBT containing the binary data of the signed transaction and other metadata. Then you add a new derivative path to PSBT using bip32.reative:
`bash
WalletprocessBT finalizes PSBT TXID1 TXINMAP = 0x1234 0x5678 -Riva = MyDerivation --addpath = BIP32PATH
The process portfolios will return an object containing the finalized PSBTs and other metadata, including the hash of the transaction as a hexadecimal string.
In summary, when you add a new derivative path to an already signed and finalized PSBT using WalletprocessBT, the command returns an object containing the finalized PSBT and other metadata. The transactional hex not returns directly; Instead, it is built into this site.
