Confirm own incoming transactions


This might only be an issue with the terminology, but when a transaction is "mined", it is included in a block. You could do that of course, if you were contributing blocks to the Bitcoin network, but the computing power of the network has grown to levels where it is infeasible to mine at home.

What you can do, is to verify the validity of an incoming transaction. Your Bitcoin wallet software does this automatically when it receives the transaction. It checks that the inputs are available for spending, and the signature matches the source of the funds. However, until a transaction is not part of a block in the longest valid chain, it is unconfirmed and may yet be replaced by a competing transaction spending the same funds. Therefore, you cannot "confirm a transaction...

Transaction confirmation is needed to prevent double spending of the same money.


Usually when new Bitcoins are earned the owner isn't free to utilize them immediately. As soon as transaction is started it is sent to Bitcoin network for proccessing and has to be included in a block before becoming legitimate. The process of implementing a transaction in a newly found block is called a transaction confirmation. Inclusion in one block = one confirmation and when there are six or more of such confirmations the transaction is considered confirmed. This feature was introduced to protect the system form repeated spending of the same bitcoins (double-spending).

Inclusion of transaction in the block happens along with the process of mining.

The issue:

A number of customers have informed us of incoming transactions to their Coinbase wallets which are slow to confirm and remain in pending for several hours.

If your transaction is shown as confirmed by other wallets or block explorer's see the update below.

The cause:

These delays are a result of the continued growth of bitcoin transaction volume, which is exceeding the processing capacity on the Bitcoin Network. As a result, transactions with a lower miner's fee are less likely to be successfully confirmed.

@brady's post provides more background on the subject:

Although we understand the frustration of customers affected by this issue, Coinbase unfortunately can not influence the confirmation time of incoming transactions. Transactions which are slow to confirm will disappear from your Coinbase wallet after a few days, and should...

Incoming Transactions | Localbitcoins


I have bitcoins that have been sent to my local bitcoin wallet. but they are kept in incoming transactions without being loaded into my wallet.,


Transactions need to be confirmed.


Who should confirm them & if its me how do i confirm it?


Hop on one leg with one eye closed clapping. That should do it.


But honestly, there nothing you can do until it confirms. Takes 3 confirms here for them to be applied to your local wallet. Time of confirmations vary. Usually 2 hours and it will confirm.


> @localbitcoins:Lelem > Who should confirm them & if its me how do i confirm it? You've been here for a couple of months now... Have you never added btc to your LBC account before? It always takes minimum a half hour to get 3 confirmations from the btc network before you can spend...

Hi guys, hope this is the right forum for this.

I'm working on a bitcoin app and one thing I haven't figured out is how to keep track of incoming transactions. I don't actually own the keys so I likely would have to use an API to get it. Any idea on the easiest way to do that?

I looked around, API limits the number of requests you can make, so it won't work for me. apparently has no limits(?), but I'm having a hard time finding the data I need among all the gibberish.

This is an example of it:

Where is the value of incoming transactions? I searched for "value" and "input" but it shows too many hits, it also shows outgoing transactions (not what I want) and all kinds of other values I have no idea what they are. Is there no easier way to find it?

I'd also like the get the time the transactions was made and the number of confirmations (or at least...

Yes, thanks for asking!

There are minimum deposit amounts, depending on the currency

Bitcoin - minimum 0.0001 BTC Blackcoin BLK - minimum 0.1 BLK Dash DASH - minimum 0.001 DASH Dogecoin DOGE - minimum 10 DOGE Emercoin EMC - minimum 0.01 EMC Litecoin LTC - minimum 0.005 LTC Monero XMR - minimum 0.001 XMR Peercoin PPC - minimum 0.01 PPC Primecoin XPM - minimum 0.1 XPM Reddcoin RDD - minimum 100 RDD Zcash ZEC - minimum 0.0001 ZEC

Incoming transactions below the above mentioned minimums are not processed by our accounting system and will not be credited to your account. We also can not accumulate smaller payments or return it back to sender.

Why we do this? Incoming micro-transactions disrupt our service when it comes to sending your cryptocurrency payments. When there are too many input transactions get included in an outgoing transaction, system gets "Transaction too large" error and cannot automatically sign it. This is due to lots of tiny incoming transactions...

So you want to build a bitcoin startup?

Building any reasonably sized web app is complex but building a bitcoin app requires an additional layer of code to interface with the blockchain and the expertise to secure it. A peer to peer marketplace includes additional challenges on top of that. The book can come later but for now here is a short developers brain dump for those crazy enough to go down this road. Have a cup of joe ready.

This article will be simple for developers who understand a little bit of how bitcoin’s blockchain technology works – unconfirmed transaction, block, blockchain, confirmations etc… If you know about them, then you will swim through it

The Paxful example

Paxful took around 6-8 months to build a fully working bitcoin peer to peer marketplace.

This was for the MVP that has all the functionality that other the marketplaces already have. All of us have at least 5 years of software development experience including...

Users of WM Keeper WinPro (Classic), WM Keeper WebPro (Light) and WM Keeper Standard (Mini) can enable confirmation of transactions and operations via SMS.

This option doesn’t require registration with E-num. Confirmation code is sent via SMS to your mobile phone provided in your registration data (in your WebMoney passport)

To enable this option please go to a specially designed webpage of the security service.

The number of short messages that can be used to confirm operations not related to transfer of funds (e.g. adding new contacts, key changing, etc.) is limited

When transactions (transfer of funds, payments via, etc) are confirmed, the WebMoney fee is increased to:

0.05 WMZ, 1.50 WMR, 1.50 WMU, 0.1 WMB, 9.00 WMK, 0.05 WME, 0,06 WMX 0.01 WMG.

Thus, if you wish to send 1 WMZ, you will be charged 0.01 WMZ (0,8%) + 0,05 WMZ (SMS fee) = 0.06 WMZ.
If you send 100 WMZ you will be charged 0.8 WMZ (0.8%) + 0.05 WMZ...

If you have sent a bitcoin payment in the last couple of weeks, you may have noticed that your transactions are taking much longer than expected to confirm.

We have received your emails.

Since, like the Bitcoin network, we are currently working through a backlog, we want to thank you for your patience. With the high volume of questions we're getting about delayed payments, we decided it would be best to write a short explanation about what's happening with many bitcoin transactions right now.

Transactions on the Bitcoin network itself aren't controlled or confirmed by BitPay, but by the bitcoin miners which group transactions into "blocks" and add those blocks to the Bitcoin "blockchain" – the shared historical record of all transactions. When a transaction has been added to a block six blocks ago, it's considered a done deal.

Currently, bitcoin network traffic is unusually high due to increasing demand for transactions per block. Block sizes are...

The number of transactions on the Bitcoin network has steadily increased over the years. This means more blocks are filling up. And as not all transactions can be included in the blockchain straight away, backlogs form in miners’ “mempools” (a sort of “transaction queue.”)

Miners typically pick the transactions that pay the most fees and include these in their blocks first. Transactions that include lower fees are “outbid” on the so called “fee market,” and remain in miners’ mempools until a new block is found. If the transaction is outbid again, it has to wait until the next block.

This can lead to a suboptimal user experience. Transactions with too low a fee can take hours or even days to confirm, and sometimes never confirm at all.

But here is what you can do today to keep your own transaction from getting stuck.

For the first years of Bitcoin’s existence, most wallets added fixed fees to outgoing transactions: typically, 0.1...

Frequently in popular descriptions of Bitcoin and in the user interfaces of wallet software, a distinction is made between “confirmed” and “unconfirmed” transactions. What is the difference?

At a high level, a transaction is only confirmed when it is permanently included in the Bitcoin blockchain. The blockchain is a ledger of all transactions in the history of Bitcoin. It is append-only, meaning new data can be added to the end of the ledger, but data can never be removed once included. This ledger is necessary to prevent double-spending, which is a key technical challenge in designing any cryptocurrency.

How Bitcoins are Transferred

Recall that if Alice “owns” some quantity of bitcoins, this really means she knows one or more cryptographic keys which have been designated as the controller of those coins in a transaction on the ledger which transferred the coins to Alice. In order to transfer the coins to another entity, Alice will use these keys to produce a...

The bitcoin system, unlike traditional banking and payment systems, is based on de-centralized trust. Instead of a central trusted authority, in bitcoin, trust is achieved as an emergent property from the interactions of different participants in the bitcoin system. In this chapter, we will examine bitcoin from a high level by tracking a single transaction through the bitcoin system and watch as it becomes "trusted" and accepted by the bitcoin mechanism of distributed consensus and is finally recorded on the blockchain, the distributed ledger of all transactions.

Each example is based on an actual transaction made on the bitcoin network, simulating the interactions between the users (Joe, Alice, and Bob) by sending funds from one wallet to another. While tracking a transaction through the bitcoin network and blockchain, we will use a blockchain explorer site to visualize each step. A blockchain explorer is a web application that operates as a bitcoin search engine, in that...

Bitcoin transactions are sent from and to electronic bitcoin wallets, and are digitally signed for security. Everyone on the network knows about a transaction, and the history of a transaction can be traced back to the point where the bitcoins were produced.

Holding onto bitcoins is great if you’re a speculator waiting for the price to go up, but the whole point of this currency is to spend it, right? So, when spending bitcoins, how do transactions work?

There are no bitcoins, only records of bitcoin transactions

Here’s the funny thing about bitcoins: they don’t exist anywhere, even on a hard drive. We talk about someone having bitcoins, but when you look at a particular bitcoin address, there are no digital bitcoins held in it, in the same way that you might hold pounds or dollars in a bank account. You cannot point to a physical object, or even a digital file, and say “this is a bitcoin”.

Instead, there are only...
