• How can I check the status of my blockchain transactions?

By the end of this article, you will have a better understanding of how blockchain transactions work and how to optimize them for your needs. Let’s get started!

What are Blockchain Pending Transactions?

A blockchain transaction is a record of data that is sent from one address to another on a distributed network of computers. For example, when you send Bitcoin from your wallet to another person’s wallet, you are creating a blockchain transaction.

However, before a blockchain transaction can be finalized and added to the ledger, it needs to be validated by the network. This process is called confirmation. A confirmation means that a majority of the nodes (computers) on the network agree that the transaction is valid and follows the rules of the protocol.

Until a transaction is confirmed, it is considered pending. A pending transaction is one that has been broadcasted to the network but has not yet been included in a block. A block is a collection of transactions that are verified and added to the ledger every certain period of time. For example, Bitcoin blocks are created every 10 minutes on average.

Why are Blockchain Transactions Pending?

There are several reasons why a blockchain transaction may be pending for a long time. Some of the most common ones are:

• Network congestion: Sometimes there is a high volume of transactions being sent on the network, which creates a backlog of unconfirmed transactions. This means that there are more transactions than there is space available in each block. As a result, some transactions may have to wait longer than usual to be confirmed.
• Low fees: Each blockchain transaction requires a fee to be paid to the miners or validators who process and confirm it. The fee acts as an incentive for them to prioritize your transaction over others. However, if you set a fee that is too low compared to the average fee on the network, your transaction may be ignored or delayed by the miners or validators. This is because they will prefer to confirm transactions that offer higher rewards.
• Double-spending: A double-spending attack is when someone tries to spend the same funds twice by sending two conflicting transactions to different recipients. This can happen if someone modifies or cancels a transaction after broadcasting it to the network, or if they use malicious software or service that allows them to do so. Double-spending attempts are usually detected and rejected by the network, but they can cause delays and confusion for legitimate transactions.

How Long Do Blockchain Transactions Take to Confirm?

The confirmation time of a blockchain transaction depends on several factors, such as:

• The type of blockchain: Different blockchains have different characteristics and parameters that affect their speed and scalability. For example, Bitcoin has a block time of 10 minutes and a block size limit of 1 megabyte, while Ethereum has a block time of 15 seconds and a dynamic block size limit based on gas usage. These factors determine how fast and how many transactions can be processed by each blockchain.
• The number of confirmations required: Different services and platforms may require different numbers of confirmations before they accept or credit your transaction. For example, some exchanges may require 3 confirmations for Bitcoin deposits, while others may require 6 or more. The more confirmations required, the longer it will take for your transaction to be completed.
• The network conditions: The current state of the network also affects the confirmation time of your transaction. If there is high demand for transactions on the network, you may have to compete with other users for block space and pay higher fees to get your transaction confirmed faster. If there is a low demand for transactions on the network, you may be able to get your transaction confirmed faster with lower fees.

To give you an idea of how long different blockchains take to confirm transactions, here are some average confirmation times as of October 12, 2023:

• Bitcoin: 9 minutes
• Ethereum: 2 minutes
• Litecoin: 2 minutes
• Bitcoin Cash: 10 minutes
• Dogecoin: 1 minute
• Ripple: 4 seconds

However, these are only averages and may vary depending on the factors mentioned above. Therefore, it is always advisable to check the status of your transaction on a blockchain explorer before assuming that it is confirmed or not.

How Can I Speed Up My Blockchain Transactions?

If you want to speed up your blockchain transactions, there are some things you can do, such as:

• Increase your fee: As mentioned earlier, the fee you pay for your transaction influences how fast it will be confirmed by the network. If you want to increase the chances of your transaction being included in the next block, you can increase your fee accordingly. However, this may also increase the cost of your transaction, so you should balance the trade-off between speed and cost.
• Use a faster blockchain: If you have the option to choose between different blockchains for your transaction, you may want to use a faster one that has shorter block times and higher throughput. For example, if you want to send money to someone, you may prefer to use Ripple or Solana instead of Bitcoin or Ethereum. However, this may also involve some trade-offs in terms of security, decentralization, and compatibility. You should always do your research and understand the pros and cons of each blockchain before using it.
• Use a third-party service: If you don’t want to deal with the hassle of fees and confirmations, you can use a third-party service that offers instant or near-instant transactions. For example, you can use Lightning Network or Liquid Network for Bitcoin transactions, or Polygon or Optimism for Ethereum transactions. These services use various techniques such as payment channels, sidechains, or rollups to enable faster and cheaper transactions on top of the main blockchain. However, these services may also involve risks and limitations, such as trust issues, technical complexity, or reduced functionality. Before using these services, you should always read the terms and conditions and understand the implications.

How Can I Check the Status of My Blockchain Transactions?

If you want to check the status of your blockchain transactions, you can use a blockchain explorer. A blockchain explorer is a website or app that allows you to view and analyze the data on a blockchain. You can use it to search for transactions, addresses, blocks, and other information related to the blockchain.

To use a blockchain explorer, you need to know the transaction ID (also known as hash or txid) of your transaction. This is a unique identifier that is generated when you broadcast your transaction to the network. You can usually find it in your wallet or on the platform where you sent or received your transaction.

Once you have your transaction ID, you can enter it in the search box of the blockchain explorer of your choice. For example, if you want to check a Bitcoin transaction, you can use Blockchain.com Explorer or Blockchair. If you want to check an Ethereum transaction, you can use Etherscan.

The blockchain explorer will show you various details about your transaction, such as:

• The status: This tells you whether your transaction is confirmed or pending. If it is confirmed, it will also show you how many confirmations it has received so far.
• The timestamp: This tells you when your transaction was broadcasted and when it was confirmed by the network.
• The inputs and outputs: These are the addresses that sent and received the funds in your transaction. You can also see the amounts and balances involved in each input and output.
• The fee: This is the amount of money that was paid to the miners or validators for processing and confirming your transaction.
• The size: This is the amount of data that your transaction occupies on the blockchain.

By using a blockchain explorer, you can track and verify your blockchain transactions easily and securely.

Conclusion

Blockchain transactions are an essential part of using cryptocurrencies and other applications based on blockchain technology. However, they are not always fast and simple. They may take longer than expected or get stuck in a pending state due to various factors.

In this article, we have explained what are blockchain pending transactions, why they happen, how long they take to confirm, how to speed them up, and how to check their status. We hope that this article has helped you understand how blockchain transactions work and how to optimize them for your needs.
