Can You Cancel Unconfirmed Bitcoin Transactions? Yes, Here’s How

Every confirmed bitcoin transaction is irreversible. But is it possible to cancel unconfirmed bitcoin transactions?

Why Bitcoin Transactions Remain Unconfirmed

An unconfirmed bitcoin transaction occurs when a given transaction fails to receive a confirmation on the blockchain within 24 hours.

All bitcoin transactions must be confirmed by miners. They need a minimum of three confirmations to be considered fully confirmed.

There are two main reasons your bitcoin transaction may end up remaining unconfirmed.

1. If the transaction is very recent, you may need to wait a little longer before receiving confirmation. Currently, even at its very quickest, it takes at least 10 minutes to confirm a BTC transaction.
2. The fee for the transaction was not entirely included or was too low. One simple rule applies when it comes to bitcoin transactions: the smaller the amount, the lower its chances of a successful confirmation.

If you choose too minimal a transaction fee, it may not get confirmed by miners. If, after 24 hours, your transaction remains unconfirmed, here’s what you need to do.

Reversing Your Unconfirmed Bitcoin Transactions

Make absolutely sure that your transaction is unconfirmed before taking action. To start with, that means waiting for at least 24 hours. If there’s definitely no confirmation yet, use a block explorer like Blockchain.com to confirm that your TX is indeed unconfirmed.

As a public blockchain, it’s very easy to track your bitcoin transaction. Simply enter your transaction ID and track it through the block explorer.

Remember that transactions need a minimum of three confirmations before they are fully confirmed. If you see that your transaction has one or two confirmations, you will have no choice but to wait until it is validated by a third miner. The process has already begun.

If there are zero confirmations, you can go ahead and cancel the transaction. There are two ways of going about this:

1. Use the Replace by Fee (RBF Protocol)
2. Use the higher fee Double-Spend transaction

The RBF Protocol allows you to broadcast your bitcoin transaction to the network a second time with a higher fee to ensure that it gets picked up by miners. This will cancel your previous transaction and essentially create a new one.

However, note that not many wallets support the RBF Protocol, so be sure to check that your chosen BTC wallet does. To use the RBF Protocol simply select the option when you set the transaction as you’re sending out your bitcoin.

If RBF isn’t an option due to the wallet you use, you’ll need to go down the double spending route. This entails creating a new transaction the exact amount of the unconfirmed original. So, you basically just send the transaction again but select a higher fee this time.

Ensuring Your Transactions Are Confirmed

If you want to avoid this problem and ensure that your bitcoin transactions are confirmed each time, use the suggested TX fee setting found in most wallets. If you change it, you may choose a lower miner fee by accident that leads to an unconfirmed transaction.

Most wallets select the miner fee automatically to help you avoid waiting hours and hours for confirmation of your transaction and making sure it doesn’t get stuck in the Bitcoin block.

Transaction confirmation

Enjoyed the article? Share:

Bitcoin transaction confirmation is needed to prevent double-spending of the same money. One of the main advantages of bitcoin is that it avoids the problem of double-spending, i.e. the risk that a digital currency token may be copied and spent more than once. In spite of having no central authority to verify that its tokens are not being duplicated, bitcoin successfully avoids double-spending through a system of decentralized transaction confirmation, based on the consensus of its users. Bitcoin transaction time is always changing and it depends on the miner’s fee.

How to confirm bitcoin transaction? [ edit ]

A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain [1] . Bitcoin transactions are not immediate. When a user wishes to send bitcoins, information is broadcast from her wallet to the (users in the) network, who verify that she has enough coins, and that they have never been spent before. Once validated, miners will include this transaction – along with others – in a new block in the blockchain. This is called a transaction confirmation. The transaction is now said to be «unconfirmed bitcoin transaction».

Each time a new block is added to the chain (every ten minutes), the transaction is said to be confirmed again. As a consensus, many users wait for a transaction to be confirmed six times (after roughly sixty minutes) before accepting it as payment, to avoid double-spending. Users will usually show a transaction as «n/unconfirmed» until it is six blocks deep.

Bitcoin Confirmation Time [ edit ]

To answer the question «How Long Does It Take To Transfer Bitcoin» it needs to understand that bitcoin transaction confirmation time depends on many factors. The deeper a transaction is buried, the harder it will be to manipulate. Although 0/unconfirmed transactions could be reversed via Finney attack, race attack, or 51% attack, small amounts of money will not be worth the trouble. Larger sums are worth protecting under more bitcoin confirmations. The number six is just an arbitrary limit, beyond which the feasibility of an attacker being able to amass more than 10% of the network’s hashrate for purposes of a transaction falsification becomes negligible (a risk lower than 0.1%).

Having understood how transactions occur, you should find out what affects the speed of processing and verification of information. To speed up the process, you need to know that it can slow down. Usually at the final time is affected by:

• network utilization;
• sharp jumps in the course;
• low commission.

The influence of the first factor is especially noticeable. When the system needs to process many requests, users have to wait. Especially long we have to wait in the days of peak activity, which is not often, but sometimes. Of great importance is the Commission paid to miners. The bigger it is, the higher the priority will be.

How long does bitcoin take to send? The size of the transaction has an influence on bitcoin confirmation time. It also has an additional impact: sending large amounts is much faster.

How many confirmations in bitcoin needed? [ edit ]

Although six confirmations is the consensus, merchants and exchanges that accept bitcoin as payment for their products and services should set their own standard of confirmations they require before accepting payment.

Freshly-minted bitcoins can only be used after 100 confirmations, to prevent coins from orphan blocks being spent. Older bitcoin client will not use newly-earned coins until they have 120 confirmations.

Number of Bitcoin Confirmations [ edit ]

A regular bitcoin client will show the transaction as “n / unconfirmed” until its size in the chain becomes 6 blocks. Users and cryptocurrency exchanges that accept bitcoins as payment set their threshold in the number of required blocks until the payment is confirmed.

To find out how many checks are required to process the transaction and how long to wait for the receipt of funds, it is necessary to understand the features of cryptocurrency transfers. This process consists of several stages:

• addressee sends money;
• information about transactions is made in special blocks, each of which has a room and a hash (special data);
• the blocks are sent for scanning to different computers;
• if everything is done correctly, the received information replenishes various databases;
• checked blocks complete the chain;
• the money goes to the recipient.

To make a transfer, the transaction must be verified in 6 blocks. If this does not happen, cryptogenic reach the final destination. Accordingly, the speed of bitcoin confirmations depends on the time of sending Finance.

Bitcoin transaction accelerator [ edit ]

Theoretically, it is impossible to speed up the confirmation of bitcoin transactions. Because it is impossible to increase the speed of data processing on another computer. But the reality is somewhat different. Cryptocurrency holders can take advantage of several options:

• the increase in the size of the commission;
• using proven reliable wallets;
• the opening of the transaction;
• using multifunction purses that support the creation of multipurpose.

Additionally, visitors can use the alternative, involving the procurement transaction as a reserve. This option requires the creation of a private, independent from the wallet address bitcoins.

Depending on conditions the time of making the bitcoin payment can be both immediate and delayed for a few days. Therefore, in order not to be in a difficult situation, you should think in advance about all the details and decide how to speed up the process. And the most important is the size of the Commission and the reliability of the selected wallet. If miners get a good reward, the priority of data processing will increase dramatically. A high-quality payment resource is able to make a financial transaction instant.

General format of a Bitcoin transaction (inside a block) [ edit ]

Field	Description	Size
Version no	currently 1	4 bytes
Flag	If present, always 0001, and indicates the presence of witness data	optional 2 byte array
In-counter	positive integer VI = VarInt	1 — 9 bytes
list of inputs	the first input of the first transaction is also called «coinbase» (its content was ignored in earlier versions)	-many inputs
Out-counter	positive integer VI = VarInt	1 — 9 bytes
list of outputs	the outputs of the first transaction spend the mined bitcoins for the block	-many outputs
Witnesses	A list of witnesses, 1 for each input, omitted if flag above is missing	variable, see Segregated_Witness
lock_time	if non-zero and sequence numbers are Principle example of a Bitcoin transaction with 1 input and 1 output only [ edit ]

Data [ edit ]

Explanation [ edit ]

The input in this transaction imports 50 BTC from output #0 in transaction f5d8. Then the output sends 50 BTC to a Bitcoin address (expressed here in hexadecimal 4043. instead of the normal base58). When the recipient wants to spend this money, he will reference output #0 of this transaction in an input of his own transaction.

Input [ edit ]

An input is a reference to an output from a previous transaction. Multiple inputs are often listed in a transaction. All of the new transaction’s input values (that is, the total coin value of the previous outputs referenced by the new transaction’s inputs) are added up, and the total (less any transaction fee) is completely used by the outputs of the new transaction. Previous tx is a hash of a previous transaction. Index is the specific output in the referenced transaction. ScriptSig is the first half of a script (discussed in more detail later).

The script contains two components, a signature and a public key. The public key must match the hash given in the script of the redeemed output. The public key is used to verify the redeemers signature, which is the second component. More precisely, the second component is an ECDSA signature over a hash of a simplified version of the transaction. It, combined with the public key, proves the transaction was created by the real owner of the address in question. Various flags define how the transaction is simplified and can be used to create different types of payment.

Output [ edit ]

An output contains instructions for sending bitcoins. Value is the number of Satoshi (1 BTC = 100,000,000 Satoshi) that this output will be worth when claimed. ScriptPubKey is the second half of a script (discussed later). There can be more than one output, and they share the combined value of the inputs. Because each output from one transaction can only ever be referenced once by an input of a subsequent transaction, the entire combined input value needs to be sent in an output if you don’t want to lose it. If the input is worth 50 BTC but you only want to send 25 BTC, Bitcoin will create two outputs worth 25 BTC: one to the destination, and one back to you (known as «change», though you send it to yourself). Any input bitcoins not redeemed in an output is considered a transaction fee; whoever generates the block can claim it by inserting it into the coinbase transaction of that block.

Verification [ edit ]

To verify that inputs are authorized to collect the values of referenced outputs, Bitcoin uses a custom Forth-like scripting system. The input’s scriptSig and the referenced output’s scriptPubKey are evaluated (in that order), with scriptPubKey using the values left on the stack by scriptSig. The input is authorized if scriptPubKey returns true. Through the scripting system, the sender can create very complex conditions that people have to meet in order to claim the output’s value. For example, it’s possible to create an output that can be claimed by anyone without any authorization. It’s also possible to require that an input be signed by ten different keys, or be redeemable with a password instead of a key.

Types of Transaction [ edit ]

Bitcoin currently creates two different scriptSig/scriptPubKey pairs. These are described below.

It is possible to design more complex types of transactions, and link them together into cryptographically enforced agreements. These are known as Contracts.

Pay-to-PubkeyHash [ edit ]

A Bitcoin address is only a hash, so the sender can’t provide a full public key in scriptPubKey. When redeeming coins that have been sent to a Bitcoin address, the recipient provides both the signature and the public key. The script verifies that the provided public key does hash to the hash in scriptPubKey, and then it also checks the signature against the public key.
