Bitcoin: What is the circular dependency in signing a chain of unconfirmed transactions?
Round dependence on signatures: Understanding the chain of unconfirmed events
In Chapter 6 of Bitcoin Management, we examine some of the unique aspects of Bitcoin protocol, including the concept of block time and the role of network validation in ensuring the consistency of events. However, there is another critical aspect that often goes unnoticed: a round addiction problem by signing the chain of unconfirmed events.
problem
When the user starts a new event on the Bitcoin network, it will be sent to the entire network for certification. To validate and add this event to Blockchain, several nodes (computers) must check its existence by checking that:
- There is enough funds in the sender’s wallet.
- The address of the recipient is in Blockchain.
3.
However, the confirmation process includes a complex transaction series, each signed and transmitted independently with several nodes. This creates a chain of unconfirmed events that can lead to round addiction.
Round dependence
Imagine this scenario:
- The user sends 10 Satoshis (smallest Bitcoin unit) to (A).
- The sender sends the event to the network but has not yet been confirmed.
- Node ensures the existence of address A and decides that the event is valid.
- To check this event, the second node must send confirmation to B, which has sufficient funds in its wallet.
But here is the problem: if the knot C (third knot) wants to add a confirmation from the node D (which has been confirmed to Blockchain, it must first receive and confirm the unconfirmed event E (which sent Satoshis A). Node E then ensures that the knot F (with enough funds in the wallet) is online.
This creates a round addiction: Node C waiting for nodes E and F to supplement their certification phase before the confirmation, which means that it can only check the events once they have confirmed at least one other node. This inefficiency can lead to slower event processing times and reduce overall network research.
Meteracking a round dependence
To solve this question, Bitcoin protocol is based on a technique called “Pow” (POW). When demanding nodes to solve complex mathematical puzzles, they must also ensure that other nodes have sent all the events in the block correctly. This creates a decentralized validation process that ensures the consistency of events without trusting in one node.
In addition, the use of a network drive, which takes the delay between the transmission and authentication of each event, helps prevent round addictions. The longer it takes to ensure the event, the more time will be increased to the time of the block, reducing the likelihood of round addictions.
conclusion
In summary, the round dependence on signing the chain of non -strengthened events is a natural problem arising from the complex authentication process associated with Bitcoin’s validation protocol. However, by utilizing techniques, such as evidence of work and network times, the protocol can alleviate this problem and ensure consistent events processing times over the network. The development of decentralized applications is still growing, and understanding and solving these challenges becomes increasingly important in the construction of a safe and efficient Blockchain infrastructure.
