Bitcoins parameter “inputs” and “output_weights” in Fundrawtransaction

If you use the command line tool from Bitcoin-Cli, you can record problems if you try to add a transaction with certain inputs from your wallet. In this article, we will immerse ourselves with what the “weight” parameter does in “Fundrawtransaction”, and how it can be used effectively.

What are inputs andOutput_weights?

In Bitcoin, an input is a script -Hash that indicates which output this input is issued. An output weight represents the amount of coins or other assets that are transferred to its corresponding address.

When using Bitcoin-Cli Fundrawtransaction, you can specify input for your transaction by presenting them as command line arguments in the format: . The script -Hash is a clear identifier for the input book script, and the amount is the value of the output for which this input is issued.

For example:

`Bash

Bitcoin -Coin Fundrawtransaction -Txid 1234567890abcdef

This would create a transaction with an input on the specified script -Hash and issue “x” münz units (represented by the quantity) for this output.

What is output_weights?

In Bitcoin, inputs are considered “weighted” because each input is assigned several outputs. Every output weight indicates how many coins or assets are transferred to its corresponding address for this input. In other words, an input with a high output weight means that you can spend more coins for this output.

When using Bitcoin-Cli Fundrawtransaction If an input is assigned several outputs, you must specify the output weights for these inputs.

How to use input_weights

To add inputs with certain outputs that have been generated from your wallet, you can use the “input_weights” parameter together with the command line argument “inputs”.

`Bash

Bitcoin-Cli input weight

For example:

`Bash

Bitcoin-Cli input weight my_wallet address 1000000 2

This would determine that you want to spend at least “X” münze units for the first edition and use a weight of “Y” for this issue.

Example uses

Suppose you have a wallet with an address called “MyWallet” and two outputs: edition A (1 BTC) and edition B (5 BTC). You would like to spend 10 BTC out of your wallet for output and with the script hash :

`Bash

Bitcoin -Coin Fundrawtransaction -Txid 1234567890abcdef MyWallet 2

The output would be a transaction with inputs and outputs that are specified in the above format. To add an input for this transaction, you can use the “Fundrawtransaction” “Input weight” command:

`Bash

Bitcoin -Cli Fundrawtransaction -TXID 1234567890abcdef MyWallet Input devices MyWallet Address 10 2

This would find that you want to output at least 10 coin units for issue A (1 BTC) with your item of items.
