Evaziv Bitcoin Utxo: Can never be spent?
Bitcoin basic technology allows a system of decentralized and confident transaction. However, in terms of any digital currency, there are limits to the conviviality of unattitutional transaction outputs (UTXO). Such a limitation is that some UTXO cannot be spent.
In this article, we will immerse ourselves in the world of Bitcoin Utxos, we will explore why they cannot always be spent and we will examine real examples of the first days of the network.
What are I UTXOS?
Utxo de Bitcoin (transaction is not spent) is a digital recording of a transaction that has been broadcast on the network. Contains scriptpubkey associated with the transaction, which defines how to spend production. When a user spends a UTXO by sending him as a starter for another transaction, he “unlocks” the funds associated with this transaction.
Why can’t some UTXO spend?
The reason why some UTXO cannot be spent is due to the scriptpubkey configuration. A scriptpubkey determines how to spend an exit according to the public key to a private key associated with it. In Bitcoin, most users have only one output outing for each private key. However, when a new transaction is broadcast on the network, a UTXO can be created that cannot be spent due to its scriptpubkey configuration.
There are two main reasons why some Utxo cannot be spent:
- Invalid Scriptpubkey : In rare cases, the private key to a user can have a scriptpubkey that is not valid for the height of the block or non -current (a unique number used to ensure that the transaction is broadcast to the right time ). When this happens, even if there are other UTEXos with valid scripts, they cannot be spent because of their unlikely scriptpubkeys.
- Scriptpubkey collision : Another reason for some UTXO cannot be spent is that two or more users have private keys with the same public key, which would cause a scriptpubkey collision. This would prevent one of these users from spending their outputs.
Real examples
To illustrate this concept, consider two real examples:
- Example 1: Bitcoin Cash (BCH)
In November 2017, BCH was taken from the original Bitcoin blockchain. One of the main differences between BCH and Bitcoin original is that BCH uses a different scriptpubkey configuration for certain UTEXOS. As a result, BCH users cannot spend these exits without manually reconfiguring their scripts or creating new UTEXOS.
Example 2: Segwit
In July 2017, the modernization of Segwit was implemented on Blockchain Bitcoin. This update has allowed more compact and efficient transactions by dividing the block into smaller segments. However, some UTXOs created with old scriptpubkey configurations during this period still cannot be spent due to their scriptpubkey configurations.
Conclusion
Although this is not a universal rule that all UTXO can never be spent, there are cases where they cannot be due to the scriptpubkey configuration or other technical limitations. Understanding these limitations is crucial to Bitcoin users and developers to ensure network integrity and prevent potential security vulnerabilities.
While the Bitcoin ecosystem continues to evolve, it is essential to keep up to date with the latest developments and updates of the Bitcoin community to evaluate the UTEXO subtleties and their expense capabilities.
