After opening your Blockchain wallet, touch the "Receive" button in the lower right hand side of the screen. The window that opens will show a QR code and alphanumeric representation of you public Bitcoin address. You can have the QR code scanned to receive Bitcoin. You can also copy the alphanumeric and send that to receive. Dec 05, · Each public address your wallet generates stems from your wallet's xPub (or Extended Public Key). Once your public address receives an incoming payment, a new address will automatically be generated and display when you click on Request.

A standard P2PKH address has something like 34 signs and starts with a 1. Every wallet software you use can easily create a P2PKH address, or, to be more precise: find as many of it as you want. It is no rocket science, but a combination of several non-exceptional cryptographic operations. ECDSA is the cryptographic algorithm in the core of bitcoin addresses.
With ECDSA you can give the world easily the information to prove that you — and only you — are the author of a message by signing it. So, after creating the private key with entropy, the wallet derives the public key from it. It does so by picking some random coordinates on a certain elliptic curve and doing some calculations.
Details are not important. What matters ist, which this public key is all you need to send and collect payments. In the early days, the public key was used to receive funds. But very soon the concept was extended. The public key is not only very long and unhandy — around 65 characters — but can also be subject to typing errors.
Further, exposing it can also set you on risks if ECDSA is ever broken, for example by quantum computing. This is why the bitcoin developers created a method to derive an address from the public key.
To create the address your wallet pushes the public key through a series of cryptographic algorithms. Roughly speaking this is what happens:. The four checksum bytes are generated by hashing the result twice with SHA and taking the first four bytes. Then your wallet converts the result into a base58 string. Whenever you paste an address in your bitcoin wallet, it checks the prefix and calculates the checksum. This makes it impossible to send funds to a wrong address due to a typing error.
If you have the private key for an address, only you can sign a transaction with cryptocurrency token assigned to this address — while everybody who knows your address can verify the validity of your signature. This simple process — signing a transaction, verifying the signature — is more or less everything a cryptocurrency transaction does.
But bitcoin has more advanced addresses: the so-called P2SH addresses. This kind of addresses enable more flexible methods to verify yourself, for example, those that are used in multisig-addresses, in which two parties provide information which sums up to the needed script.
However, it needs another guide to completely describe the magic of P2SH addresses. Here we focus on addresses itself and leave bitcoin to have a look, how other cryptocurrencies create addresses. A lot of cryptocurrencies use nearly the same address format as bitcoin. As these coins use the same cryptographic algorithm, you can use the same private and public keys to save coins in all these cryptocurrencies. Partly you can even store them on the same addresses. For example, Litecoin and bitcoin use the same prefix for P2SH addresses — 05 — so that it is possible to store both Bitcoin as Litecoin at the same address.
Other cryptocurrencies, however, use other schemes to generate the address. For example, Monero is based on the Cryptonote algorithm. This algorithm deploys another cryptographic signature algorithm to generate the public key, EdDSA.
For this reason, Cryptonote addresses must contain two public keys, a view, and a spend key. Like with bitcoin addresses, Cryptonote adds a prefix byte and hashes the result. However, it uses Keccak instead of double SHA to generate four checksum bytes, which are added at the end of the string.
After converting the result to base58, you get the final address, which is longer than in bitcoin. Get Spins Get Spins Sponsored. Buy Crypto Buy Crypto Sponsored.

Within the Manage section, to the right of the name, is a button called More Options. Pressing it will open a dropdown of additional functions. The rest have the following:. In the mobile app, press the three horizontal lines in the upper left corner to open the menu and select Addresses.
We strongly recommend having an excellent understanding of bitcoin address generation and private keys before making use of this feature. Imported addresses can be archived, so that their transaction histories and balances are hidden from the rest of the wallet. The rest have the following: Edit name : Choose this option to edit the name of the sub-wallet Make default : This option allows your chosen sub-wallet to replace My Bitcoin Wallet or your current default wallet.
Archive : This option will archive the sub-wallet, so that none of its addresses or balance are included in your overall wallet balance or transaction history.
