To address those risks, developers in the bitcoin community have come up and implemented a new method of generating keys, giving birth to deterministic wallets.

What is a, bitcoin wallet?

However, these entries are not associated to a physical identity, but to a bitcoin address - a seemingly random string of 34 alphanumeric characters. Both only exist in the digital realm.

Then, she uses the key stored in her wallet to open her locker, withdraws the money inside and then signs it (it's a bit like a cheque).

It is important to note that software wallets, regardless of the device they are on, are not as secure as hardware wallets given their digital nature. You can unsubscribe with one click.

However, under the hood there are fundamental differences between the two, the key being that a Bitcoin wallet does not actually store any bitcoin.


To make a transaction, a user must prove that he controls that address. This was a huge leap in safekeeping users bitcoins, and most wallet software nowadays are deterministic. By design, most exchanges have wallets built in to allow for deposits and withdrawals of different assets.

Any Bitcoin sent to this address will be added to your Luno account.


Here are the best ways to store bitcoin securely in bitcoin wallets

After that, the public key goes through yet two hash functions, and the resulting string is compressed to its final valid format of 64 alphanumeric characters. The most important quality of hardware wallets is the physical protection of your what is a bitcoin wallet private keys, as opposed to protecting them on the computer. In this case, who controls the controllers? Summary So thats how Bitcoin wallets work in a nutshell. All of these steps are one-way, meaning that you cant deduce the originating key from the resulting one. Don't worry, bitcoin is safe Let's illustrate how it works with a rough analogy.

Also, this means that even if you imported your keys into the same wallet at another device, they would not sync - since each wallet would independently generate different keys when creating a transaction. A Bitcoin wallet address is similar to a bank account number. If a user wants to create a paper wallet, they would, for example, need to take extra precaution that the computer from which the keys are being generated has not been infected with any viruses. However, before he can actually spend it, he needs to wait for a qualified deposit box inspector (a bitcoin miner, in this case) to drop by and confirm that the money is really there, and that Alice. So, the question of how to securely store bitcoin comes down to the security of these keys. In fact, a bitcoin is nothing more than the sequence of all its previous transactions, all the way back to its generating block coinbase transaction (the first transaction on each block, rewarding miners with new bitcoin).

The transaction is included in the next block to be confirmed by a miner, that validates the corresponding signatures/keys, and then added to the blockchain. In this respect, electronic fiat money and bitcoin are not that different. Lets take a step back and ask an apparently simple question: who owns your money? The most popular of these are cryptocurrency exchanges. Both exist only as long as they are accounted for in a digital ledger.
