A user will provide you with a receiving address when they are expecting to be paid. The receiver allows you to encrypt the Bitcoins you are sending with their public key. After encryption, the only way to access the coins, and thus spend them, is to decrypt them with the private key. It is common for a user to provide a new public key each time they expect payment. This behavior is not mandatory, however. Since a user is encouraged to give out many public keys for their transactions they are left with many private keys that access the coins.
These private keys are stored in what is called the wallet. The value inside your wallet your wealth is locked away inside a complex mathematical formula using your public key. The only key to this lock is essentially the answer to that formula: the private key.
Anyone with access to the private key owns the right to spend the Bitcoins associated with it. By default, the file that contains the private key is not encrypted. This leaves the private key open to attack and theft. Keeping your private key s encrypted is a security imperative.
Similarly, if you lose your wallet, you lose your private key s. This file should remain protected with encryption and regularly backed up. Once the transaction has been mined inside a block in the blockchain it will be available to view from a website that tracks the Blockchain. See below for an example. Notice that all information about the transaction is publically available except for the private keys. This information is available for every transaction that has ever occurred in the blockchain to anyone who wants it.
Also notice, however, that we did not associate our accounts with names, email address, etc. No identifying information is ever needed to take part in a Bitcoin transaction. The only thing tying a user to their Bitcoins is the private key associated with the public key to which Bitcoins were sent. Learning how to use Bitcoin using the Testnet is quick and simple.
It is possible, in just a few steps, to learn how to install and encrypt a wallet, receive coins, spend coins, and track transactions all without spending real money. All of the steps described above also apply to Bitcoin Core when it connects to the main blockchain. Also, make sure to send borrowed Testnet coins back to the faucet website from which they came.

They have no market value. Would you sell Monopoly bills? Of course not! If successful, it will return an HDWallet but only with the newly derived address es represented in its chains field to limit the data transmitted; for the full address list after derivation, you can follow up this API call with the Get Wallet Addresses Endpoint. While most of these public addresses are reference points for single private keys that can "unlock" the newly created UTXOs, occasionally they are sent to more exotic addresses through pay-to-script-hash , typically multisignature addresses.
The Transaction Hash Endpoint returns detailed information about a given transaction based on its hash. The returned object contains detailed information about the transaction, including the value transfered, date received, and a full listing of inputs and outputs. Provide this in a partially-filled out TX request object. As you can see from the code example, you only need to provide a single public address within the addresses array of both the input and output of your TX request object.
While this particular usage will differ between client libraries, the result is the same: the addresses within your wallet will be used as the inputs , as if all of them had been placed within the addresses array. With your TXSkeleton returned from the New Transaction Endpoint, you now need to use your private key s to sign the data provided in the tosign array. Digital signing can be a difficult process, and is where the majority of issues arise when dealing with cryptocurrency transactions.
We are working on integrating client-side signing solutions into our libraries to make this process easier. You can read more about signing here. In the mean time, if you want to experiment with client-side signing, consider using our signer tool. Signature and public key order matters, so make sure they are returned in the same order as the inputs you provided.
Signing and creating transactions can be one of the trickiest parts of using blockchains in your applications. By default, we allow unconfirmed UTXOs as inputs when creating transactions. We will compute change and fees the same way. Fees in cryptocurrencies can be complex. We provide 2 different ways for you to control the fees included in your transactions:. To learn more about fees, bitcoinfees.
These are the possible script types:. We also offer the ability to decode raw transactions without sending propagating them to the network; perhaps you want to double-check another client library or confirm that another service is sending proper transactions. This allows you to double check the which input you are spending and the value transfered. Multisignature transactions are made simple by the method described in the Creating Transactions section, but they deserve special mention.
In order to use them, you first need to fund a multisignature address. The code example demonstrates how the partially filled TX request object would appear. If it returns with an HTTP Status Code , then your multisignature address via a pay-to-script-hash address is funded.
Once funded, you might want to programmatically spend the money in the address at some point. Here the process is similar, but with the inputs and outputs reversed. By operating a well-connected node, we collect a lot of information about how transactions propagate; for example, our Confidence Factor relies on this connectivity. The return object is described below:.
You can get a live view of unconfirmed transaction propagation analysis on Bitcoin by connecting to our Transaction Propagation WebSocket, at the following address:. As soon as an unconfirmed transaction hits 10 peers, we send the object described above through this WebSocket. So what does that confidence attribute actually mean? In simpler terms, if an unconfirmed transaction returns a confidence factor of And that pride extends to our own confidence in our confidence product.
Check out a live view of bitcoin and click on one of the most recent unconfirmed transactions. There are a host of factors that go into our confidence calculation, but you can broadly organize them into two categories. The behavior of transactions refers to aspects of transactions that do vary with time time-variant in our model. On the shape side of our model, we ask a number of questions about a transaction: How is it structured? What are its inputs and outputs? Broadly speaking, without knowing anything about the network, does it look like this transaction will be confirmed soon?
The behavior part of our model primarily focuses on how a transaction propagates through the network. In order to model this correctly, you need both a great connection to the network and a lot of past data, which we have. By monitoring transaction propagation, the number of nodes that have received it, and how quickly they received it, we can calculate its probability to be the "winning" transaction at any given point in time, if a double-spend was attempted.
The result is a robust and reliable metric for judging unconfirmed transaction confidence, especially when used in concert with webhooks and websockets. Our work here is based on several public research results in addition to our own in-depth follow-up research, which you can read about here. We are constantly improving our confidence model, and we always publish our findings when we do.
The returned TXConfidence object contains the all-important confidence percentage, receive count and more. You can find an unconfirmed transaction hash from our block explorer here. Cryptocurrency addresses, transactions, and blocks are extremely powerful, but the labels they employ can be The Metadata API supports both public and private key-value storage. Public metadata is immutable ; once set, it cannot be modified or deleted. If you accidentally set public metadata and need it deleted, contact us.
Consequently, private metadata is associated and only accessible with your user token. The methods for interacting with metadata are outlined below. If another key with the same name already exists under your private metadata store, supplying a new value will replace it. New key-value pairs will be added without replacing prexisting key-value pairs.
Thanks to the possibility of embedding arbitrary data through null-data outputs, a blockchain can! However, the act of creating these alternate forms of valueand choosing a format that was universally readablecan be fraught with difficulty.
We built our Asset API to simplify that process. This set of endpoints currently leverages the Open Assets Protocol , a simple, robust method of embedding assets across any blockchain that supports null-data outputs. Asset addresses are just like regular bitcoin addresses, and are generated from a private-public keypair. Note that while it returns an Address object, anything that would have represented "satoshis" now represents "amount of asset. One of the well-known benefits of cryptocurrency is the ability to allow users to partake in online commerce without necessarily requiring extensive setup barriers, like registering new accounts.
In that spirit, our Address Forwarding API is the easiest way to acceptand consolidatepayments securely without forcing your users to create accounts and jump through unnecessary loops. While there are many possible use cases, the two we hear most about are:. We do not take a fee on address forwarding, other than the required miner fee which depends on network conditions; forwards are free. However, as part of your own services, you can include a fee either fixed or a percentage that will also be automatically transfered to your own address in the same transaction.
Fee-based business models are thus easily achieved, and moreover, easily auditable via the blockchain. First, to create an address forwarding address, you need to POST a partially filled AddressForward object to the payment creation endpoint. You can see more details about these options in the AddressForward object details.
This returns the full array of your currently active address forwarding addresses, based on your token. By default, this endpoint only returns the first address forwards. If you have more, you can page through them using the optional start parameter. Blockchains are highly transactional systems. Many usage patterns require knowing when an event occurs: i. Instead of requiring you to continuously poll resources, we provide push APIs to facilitate those use cases, and support both WebSockets and WebHooks.
WebSockets are typically used in client applications when a server is not already running: e. WebHooks are the most reliable way to get event notifications but requires running a server to receive the callbacks. We automatically retry HTTP requests 5 times. We support a number of different event types, and you can filter your notification requests depending on how you structure your Event request object.
In addition to standard events, WebSockets accept a "ping" event. If you send the following, you will receive the same message back with "ping" replaced by "pong":. A regular ping i. We retry individual payloads to your url five times; if one fails, we wait exponentially between retries: 1 second, 2s, 4s, 8s, 16s. Using a partially filled out Event , you can create a WebHook using this resource.
Check the Event object description and types of events to understand the options available for your events. If successful, it will return the Event with a newly generated id. This resource deletes an active Event based on its id. Remember to include your token, or the request will fail. To guarantee the origin and integrity of the webhook data, webhooks can optionally be signed by our servers. An optional JSON attribute called "signkey" can be provided with the webhook when created to either:.
Once the "signkey" attribute is set on a webhook, all webhook requests will be signed following the shaecdsa scheme of the HTTP signatures specification. This section list all the updates in reverse chronological order. We support the new bech32m address format for v1 witness. This is fixed. The data endpoint no longer exists as it was uneconomical and thus non functional since a long time. BlockCypher Node. For regular non-segwit transaction the vsize is the same as the size.
This is how you can see how much fees you are saving by using segwit. See the TXOutput object for more details. The command is designed to work without user interaction. GetChain if err!
