Understand the process of verification of the Bitcoin transaction

Bitcoin transactions are verified via a process of several steps which guarantees the integrity and safety of the network. In this article, we will deepen the specific checks carried out in a new Bitcoin (TX) transaction and the order in which they occur.

Verification steps:

• Verification of transactions

  

  : The first step is to check the validity of the transaction itself. This involves checking this:

* The sender has a sufficient balance to send the specified amount.

* The transaction is valid in accordance with the rules of the Bitcoin protocol (for example, quantities, confessions).

• Utxo set check : according to, a node checks its UTXO set to ensure that all the required currencies are present in the direction of Coinbase. This verification stage helps to prevent spam attacks by ensuring that transactions only include valid parts.

• MEMPOOL

  validation: After checking the transaction and its dependencies (for example, witnesses), a node will generally check its memory to verify that the transaction is valid for inclusion in the main channel. This involves checking this:

* The transaction was not rejected by any previous node.

* The transaction complies with the rules of the Bitcoin protocol.

• Remote : Once checked, the transaction is transmitted more via the network by several nodes. This step guarantees that the transaction spreads to the entire network and can be checked by the nodes at the end of each block.

Node order:

The order in which these stages occur varies depending on the configuration of the node, but a typical workflow follows this:

• Utxo set check : The knot begins with this stage, ensuring that all the required currencies are present.

• Verification of transactions : The node checks the transaction in relation to its own rules and UTXO established to guarantee validity.

• MEMPOOL validation: If the transaction transmits validation, it is added to Mempool to transmit.

Basic checks against:

Its initial declaration on low -income basic checks that are made first is partially correct. Although they are not explicitly mentioned in this article, these checks are carried out in fact before other verification stages. However, its main role is to detect and prevent spam attacks, ensuring that transactions do not contain excessive or non -valid amounts.

In summary, the Bitcoin transaction verification process implies a validation sequence of several stages which guarantees the integrity and safety of the network. The verification order and the specific verifications carried out are critical to prevent spam attacks and maintain the confidence and confidence of the community.
