Blockchain Unconfirmed Transaction – What Is It and How To Deal With It (2023)

In this blogpost we go over what is a blockchain unconfirmed transaction and how to potentially resolve it.

Introduction Blockchain Unconfirmed Transaction

Blockchain technology has rapidly emerged as a groundbreaking innovation in recent years, transforming the way we exchange value and conduct transactions in a digital world. At its core, blockchain is a decentralized ledger that records transactions and stores them in a secure, transparent, and tamper-proof manner.

One of the key features of blockchain technology is that it eliminates the need for intermediaries such as banks or other financial institutions to facilitate transactions. Instead, transactions are verified and processed through a computer network that maintains the blockchain ledger.

However, while blockchain technology offers many advantages over traditional financial systems, it has challenges. One of the most significant challenges is the issue of unconfirmed transactions.

An unconfirmed transaction is a transaction that has been broadcast to the blockchain network but has yet to be added to the blockchain ledger. This means that the network still needs to validate or approve the transaction, which is not considered final or complete.

This article will explore unconfirmed transactions, why they matter, and what you need to know about them. We will also discuss some common causes of unconfirmed transactions, the associated risks, and considerations and provide tips for dealing with them effectively.

By the end of this article, you will better understand how unconfirmed transactions work and how to minimize the associated risks when using blockchain technology.

What Are Unconfirmed Transactions?

Unconfirmed transactions occur when a sender broadcasts a transaction to the blockchain network. Still, the network nodes still need to verify or approve the transaction. This means the transaction is still pending and has not been added to the blockchain ledger.

For a transaction to be confirmed and added to the blockchain, it must be validated by a network of nodes or computers. These nodes verify that the transaction is valid, that the sender has sufficient funds to complete the transaction, and that the transaction meets the network’s rules and standards. Once the network has validated a transaction, it is added to the blockchain ledger as a confirmed transaction.

The time it takes for a transaction to be confirmed and added to the blockchain can vary depending on several factors, including the network’s processing power, the number of pending transactions, and the transaction fee the sender pays. Generally, the more transaction fees the sender pays, the faster the transaction will be confirmed and added to the blockchain.

While most transactions are confirmed within a few minutes, some transactions may remain unconfirmed for an extended period. This can occur when the blockchain network is congested, and many transactions are pending approval. In some cases, unconfirmed transactions may never be confirmed and may be rejected by the network, particularly if the transaction fee paid is too low.

The significance of unconfirmed transactions lies in the fact that they are only considered final or complete once they are confirmed and added to the blockchain. This means that a sender may believe that a transaction has been completed. However, in reality, the transaction may still be pending approval. Suppose the transaction remains unconfirmed for an extended period or is rejected by the network. In that case, the sender may need to initiate a new transaction to complete the intended transfer of value.

In the next section, we will explore some common causes of unconfirmed transactions and how to avoid them.

Causes of Unconfirmed Transactions

There are several reasons why a transaction may need to be confirmed on the blockchain network. Understanding these causes can help you avoid the risks associated with unconfirmed transactions.

  1. Network Congestion Blockchain networks can become congested when too many pending transactions are waiting to be processed. This can occur when a sudden surge in demand for network resources or the network’s capacity is limited. When a network is congested, transactions with higher fees are given priority. In comparison, transactions with lower fees may take longer to be confirmed or may be rejected by the network.
  2. Insufficient Transaction Fee When you send a transaction on a blockchain network, you can include a transaction fee to incentivize miners to process your transaction. Miners are rewarded with these fees for adding transactions to the blockchain. If the transaction fee is too low, miners may prioritize other transactions with higher fees, and your transaction may remain unconfirmed for an extended period.
  3. Technical Issues can also cause transactions to remain unconfirmed on the blockchain network. For example, suppose there is a bug in the blockchain software or a node goes offline. In that case, it may not be able to process transactions, leading to delays or failures in confirming transactions.
  4. Double-Spending Attacks Double-spending attacks occur when a sender attempts to spend the same funds twice by creating two separate transactions with the same inputs. In this scenario, the network will only confirm one of the transactions, and the other transaction will remain unconfirmed. This can be a problem for merchants who accept cryptocurrency payments since they may receive a payment that appears to be valid but is later rejected by the network.

To avoid these issues, it’s essential to ensure that you send transactions with appropriate transaction fees, monitor network congestion levels, and use reputable and secure blockchain software.

The next section will discuss the risks and considerations associated with unconfirmed transactions.

Risks and Considerations Associated with Unconfirmed Transactions

Unconfirmed transactions can pose several risks to users of blockchain technology. Here are some of the most critical risks and considerations to be aware of:

  1. Transaction Reversibility Since unconfirmed transactions are not final or complete, they can be reversed or canceled by the sender. This can be a problem if a recipient accepts a payment based on an unconfirmed transaction only to find out later that the transaction was canceled. To avoid this risk, waiting for a transaction to be confirmed before assuming it has been completed is essential.
  2. Double-Spending Attacks As mentioned earlier, double-spending attacks can occur when a sender attempts to spend the same funds twice. Suppose a merchant accepts a payment based on an unconfirmed transaction. In that case, they may risk losing funds if the network later rejects the transaction due to a double-spending attack.
  3. Delayed Transactions Unconfirmed transactions can sometimes take a long time to be confirmed and added to the blockchain. This can be a problem for time-sensitive transactions or users needing to access funds quickly.
  4. Frustration and Confusion Unconfirmed transactions can frustrate and confuse users unfamiliar with blockchain technology. They may need to understand why their transaction is taking so long to be confirmed or why the network rejected it.

To minimize the risks associated with unconfirmed transactions, it’s essential to be patient and wait for transactions to be confirmed before assuming they have been completed. Additionally, users should be aware of the risks associated with double-spending attacks and take steps to protect themselves, such as only accepting payments that the network has confirmed.

In the next section, we’ll provide some tips for dealing with unconfirmed transactions effectively.

Tips for Dealing with Unconfirmed Transactions

Suppose you find yourself dealing with unconfirmed transactions on the blockchain network. In that case, there are several steps you can take to minimize the risks and increase the chances that your transaction is confirmed. Here are some tips to consider:

  1. Check the Network Status. Before sending a transaction, check the network status to see if there are any reported issues or network congestion. You can do this by visiting a blockchain explorer website or checking the official website or social media accounts of the blockchain network you’re using.

  1. Increase the Transaction Fee If your transaction has been pending for a long time, you can increase the transaction fee to incentivize miners to prioritize your transaction. This can be done using your wallet software or by resending the transaction with a higher fee.
  2. Wait for the Transaction to be Confirmed. Sometimes, the best course of action is to wait for the transaction to be confirmed. Depending on the network congestion and transaction fee, this may take a few minutes to several hours.
  3. Contact Support If you’ve followed these steps and your transaction still needs to be confirmed, you may need to contact support for assistance. This can be done through the support channels provided by your wallet software or the blockchain network you’re using.
  4. Take Precautions To minimize the risks associated with unconfirmed transactions, it’s essential to take precautions such as only sending transactions to trusted parties, double-checking transaction details before sending, and accepting payments the network has confirmed.

Following these tips can increase the chances of your transactions being confirmed and minimize the risks associated with unconfirmed transactions.


In conclusion, unconfirmed transactions on the blockchain network are a common issue that users may encounter when sending or receiving transactions. While unconfirmed transactions can be frustrating and pose risks such as transaction reversibility, delayed transactions, and double-spending attacks, there are steps that users can take to minimize these risks and increase the chances of their transactions being confirmed.

Users can improve their chances of successfully completing their transactions by checking the network status before sending a transaction, increasing the transaction fee, waiting for confirmation, contacting support if needed, and taking precautions. As blockchain technology evolves, we can expect to see more efficient and effective solutions for unconfirmed transactions.

Overall, unconfirmed transactions are a reminder of the importance of being patient and taking precautions when using blockchain technology.
