Output

A batch of bitcoins created in a transaction.

Outputs are packages of bitcoins created in a bitcoin transaction.

Each output has a lock, which means that they can only be used as an inputs in a future transaction by people who can unlock them.

Fields

Field	Data	Size	Description
Value	4baf210000000000 ⟲	8 bytes	The value of the output in satoshis.
ScriptPubKey Size	19	Variable	Indicates the upcoming size of the locking code.
ScriptPubKey	76a9…88ac		A script that locks the output.

If you want to decode the value of an output, you just need to swap the byte order, then convert from hexadecimal to decimal. That will give you the value in satoshis.

How do Outputs work?

After selecting Input(s) to spend, you can create as many Outputs from them as you like.

For each output you just:

1. Give it a value.
2. Give it a lock.

1. Value

Every output has a value. This value is given in satoshis:

2. Lock

You also place locks on outputs when you create them them. These locking scripts prevent other people from using these outputs as inputs in another transaction (i.e. spending them).

This locking code is called a ScriptPubKey.
