Change from Base64 PSBT event to raw/serial sex

In this article, we investigated the process of transforming the Base64 PSBT (Programming script binares) event into its raw and serial (hex) format. We use our Bitcoin Core Clli.

Prerequisites

• Check out the Bitcoin basics and its Blockchain architecture.

• Understanding PSBT and Base64 coding standards.

Step 1: Convert Base64 PSBT event RAW

In order to convert a Base64-coded PSBT event, we must use the PSBT ‘command tool provided by Bitcoin Core. For this purpose, the “Converttopsbt” command is used. Here is an example of how it is used:

`Bash

BitcoinCore-ClvertOPSBT

`

Replace the with a real base64 coded PSBT event, as shown at the start of the Bitcoin core.

After the PSBT event has been converted from RAW format, we must convert it to its series (HEKSA). We can re -use a "PSBT" tool or utilize thecointoollibrary for this purpose.

Bash

BitcoinCore-Cli-CoinTeol -t Raw2hex

`

Replace with a real raw trade, as shown at the start of the Bitcoin core.

Bash

BitcoinCore-Cli-CoinTeol -t Hex2RAW

`

This command produces a raw event from the original Base64 coding event.

Example Departure

Here is an example of the above steps using the Fikaal PSBT event for income:

`clear text

Base64-coded PSBT events

PSBT (“1.3.0”, {

“coding”: “Base64”,

“Scriptsig”: [“0101010000000000000000000000000000000”],

“Blocknumber”: “100000”,

“Transactionindex”: “500000”

})

`

Change Home

Here is a simple Python manuscript that converts from Base64 to RAW and then a serial hex:

`Python

import support64

Bring JSON

Def Base64_to_TSB (Base64_Transaction):

Use the PSBT command tool provided by the Bitcoin core

Output = BitcoinCore-ClvertOPSBT (Base64_Transaction)

Return JSON.LOADS (Departure)

def tsb_to_raw (tsb_json, coding = “Base64”):

Converts from the coindool library from raw to hex

If coding == “raw”:

Return Cointool (tsb_json, “hex2raw”)

Elif coding == “hex”:

Return Cointool (tsb_json, “hex2raw”)

Example of use

Base64_Transaction = “PSBT (\” 1.3.0 \ “, {\” Coding \ “: \” Base64 \ “, \” Scriptsig \ “: [0101010000000000000000000000000000000 \”, “” Blocknumber \ “” 100000 \ ” , “Transactionindex \”: \ “500000 \”}) “

tsb_json = Base64_To_tsb (Base64_transaction)

Raw_hex = tsb_to_raw (tsb_json, coding = “hex”)

Print (Raw_hex)

Output:

`

This coder example will first change the Base64-coded PSBT event to the Python Dictionary using the JSON.LODS (). Then we use the cointool library to convert it to a raw form into a hex. The result is printed as raw and serialized (hexagonal places).

conclusion

There are two steps between the Base64-coded and raw/series format (Hex) format: first conversion of the PSBT event from Base64 to RAW; Secondly, converting the Raw event to its series (HEKSA). This process can be achieved using the various tools and libraries offered by Bitcoin Core Clli.
