An offline software wallet divides the wallet into two platforms that work together. It uses an offline wallet that keeps the private keys and an online wallet that stores the public keys. The online wallet creates transactions that need to be signed using the keys that are stored offline. The main features of Electrum are: support for hardware wallets (such as TREZOR, Ledger Nano and KeepKey), and secure Bitcoin storage using an offline computer. Electrum is a good option for both beginners and advanced users. What's New? That is why it is crucial to keep this information secret and safe from prying eyes. Famerramer that point, the private key is exposed and the funds are no longer safe on the hardware. Many Internet connected printers also save printed documents to memory. This type of account creation is easier for less technical users who may have trouble backing up or understanding HD seeds.

Sie können Online Wallet anlegen, aber auch Offline Wallets, welche als Hardware Wallets verkauft werden. Wie Sie sich vor Diebstahl nutzten erfahren Sie hier. Wallet: A multisig wallet could be used to create secure offline storage with paper wallets or hardware wallets. Users should already backup their offline Bitcoin holdings in multiple locations, and multisig helps add another level of security. A user, for example, may keep a backup of a paper wallet in three separate physical locations.
They can also optionally let you setup and use Tor as a proxy to prevent others from associating transactions with your IP address.
Some wallets give you full control over setting the fee paid to the bitcoin network before making a transaction, or modifying it afterward, to ensure that your transactions are confirmed in a timely manner without paying more than you have to.
Two-factor authentication 2FA is a way to add additional security to your wallet. The first 'factor' is your password for your wallet.
The second 'factor' is a verification code retrieved via text message or from an app on a mobile device. It likely requires relying on the availability of a third party to provide the service.
Bech32 is a special address format made possible by SegWit see the feature description for SegWit for more info.
This address format is also known as 'bc1 addresses'. Some bitcoin wallets and services do not yet support sending or receiving to Bech32 addresses. Some wallets fully validate transactions and blocks.
Almost all full nodes help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Some wallets can pair and connect to a hardware wallet in addition to being able to send to them. While sending to a hardware wallet is something most all wallets can do, being able to pair with one is a unique feature.
This feature enables you to be able to send and receive directly to and from a hardware wallet. Most wallets have the ability to send and receive with legacy bitcoin addresses.
Legacy addresses start with 1 or 3 as opposed to starting with bc1. Without legacy address support, you may not be able to receive bitcoin from older wallets or exchanges.
Some wallets support transactions on the Lightning Network. The Lightning Network is new and somewhat experimental. If only used with small amounts, hot wallets should be used for your everyday Bitcoin needs.
Gox is an extreme example, but one that illustrates the importance of holding private keys. Gox was the first and largest Bitcoin exchange up until Thousands of users stored more than , bitcoins in their Gox accounts.
At the time, one may have claimed to have 1, bitcoins in a Gox account. While true at the time, as soon as Mt. Gox claimed to have been victim of theft users with bitcoins in their accounts were left empty handed.
But by storing bitcoins with a third party you are always taking on additional risk. Cold storage is achieved when Bitcoin private keys are created and stored offline.
Private keys stored offline are more secure since there is no risk that a hacker or malware could steal your coins.
There are three ways to create cold storage: paper wallets, hardware wallets, and software wallets run on offline computers. Think of cold storage as your savings account.
Multisignature wallets like Copay make it easier to share control of bitcoins between multiple parties.
If created offline, multisig can also make cold storage more secure. Multisignature wallets require multiple parties to sign transactions in order for funds to be spend.
In a wallet, for example, both parties must sign a transaction. In a multisig wallet, two of the three co-signers must sign each transaction.
Armory Multisig: Armory offers a Lockbox feature that requires any amount of up to seven co-signers to approve shared transactions.
A Lockbox is created by one party who adds additional public keys as co-signers. This solution provides a mix of flexibility and security for personal use or organizations.
Instead of requiring multiple signatures for each transaction, fragmented backups require multiple signatures only for backups. A fragmented backup splits up your Armory backup into multiple pieces, which decreases the risk of physical theft of your wallet.
Without a fragmented backup, discovery of your backup would allow for immediate theft. With fragmented backup, multiple backup locations would need to be compromised in order to obtain the full backup.
They create a multisig wallet so that no funds can be spent without the permission of both founders. If one tries to create a transaction, the other partner will be required to sign off on the transaction before money can be moved.
Users should already backup their offline Bitcoin holdings in multiple locations, and multisig helps add another level of security. A user, for example, may keep a backup of a paper wallet in three separate physical locations.
So now you know of all the different options when it comes to choosing between cold storage wallets. Let's compare them all to each other to see which one would be best for you.
Technically speaking, hardare wallets fall somewhere in between a traditional hot wallet and a pure cold storage device. With hardware wallets, the private key is stored digitally on a microchip, like a hot wallet.
But that chip is never exposed to an internet connection. Hardware wallets can be a bit easier to carry around and make transacitons with, but they are also subject to data degradation risks.
This is why many users pair them with a steel wallet as a backup. When it comes to state-of-the-art bitcoin cold storage, steel backups are definitely ahead of the curve.
Steel wallets provide the convenience of the paper wallet with the portability of the hardware wallet, but they also come with some added security features that make them worth looking into.
They can be used to backup any kind of hardware or software wallet. Typically these wallets spit out a 12 to 24 word phrase you can use to get your coins back if your main wallet is lost, stolen, or destroyed.
They can be used as a more sturdy version of a paper wallet. After you have generated your paper wallet, you can recreate the private key in the steel wallet using the provided tiles.

Steel wallets are also protected from this risk. The OpenDime is basically a cross between a hardware wallet and a steel wallet. If you're partial to the idea of carrying a paper bitcoin wallet, then OpenDime can be another viable option.
Like hardware wallets, open dimes are subject to data degredation over time. On the other hand, paper wallets use regular paper to reduce the chance of your coins being hacked.
Paper wallets keep your public and private keys on a plain sheet of paper, but they can also be modified to include a QR code to transfer data back and forth between your other cold storage devices.

However, there are a number of security concerns to take into consideration:. Your computer could be infected with malware, which would allow an attacker to see your freshly generated private keys, giving them full access to any funds you then load onto the wallet.
The website itself could also be compromised. You are trusting BitAddress not to view and record the private keys that you generate.
Lastly, printers have their own memory where the file containing your private keys could be stored. For this reason, do not use a shared printer to print your paper wallet.

A Windows or Mac virtual machine will work in a pinch. You can safely share your public key, also known as the wallet address, and use a blockchain explorer such as blockstream.
To send funds from your paper wallet, you will need to import or sweep your private key into a wallet client.
Importing a private key simply adds it to the list of keys in your software wallet, preserving its unique address. This means that if someone got their hands on your paper wallet, they could still take control of the Bitcoin on it.
Sweeping a private key transfers the funds associated with it to a new or existing address. This leaves the paper wallet empty. You can import or sweep your private key into the software wallet by scanning the QR code with your webcam or typing out the private key.
As mentioned above, both of these options run the risk of exposing your private key to any keylogger or malware, which is why you should never reuse paper wallets.
The Bitcoin network spends the entire balance of a private key and sends any leftover amount — the change — to a newly-generated private key in the software wallet.
