What Is a Paper Wallet?
A paper wallet is an offline mechanism for storing bitcoins. Unlike fiat currency, there is no physical representation of a bitcoin (or most other types of cryptocurrency). Rather, wallets that are used to store digital tokens are usually software programs that help to facilitate updates to the blockchain ledger when transactions are made. Paper wallets are different from so-called hot wallets because they operate separately from the Internet. However, they still do not store physical bitcoins; the paper quality of these wallets refers primarily to the method of access for the cryptocurrency owner.
Paper wallets were primarily popular in the early years of bitcoin. In recent years, cryptocurrency users have tended to explore other methods of securing their holdings.
KEY TAKEAWAYS
A paper wallet is a printed piece of paper that contains keys and QR codes that are used to facilitate cryptocurrency transactions.
Because they are removed from the Internet, at one point paper wallets were considered to be more secure than other forms of cryptocurrency storage.
Many investors believe that risks associated with losing, misreading, or damaging the paper wallet may outweigh the potential security benefits.
Understanding a Paper Wallet
Like a hot wallet, a paper wallet also makes use of public and private keys. Cryptocurrency users wishing to store their holdings in a paper wallet typically go through the process of printing the private key onto a piece of paper. For those who are interested in setting up a paper wallet, the first step is to visit a wallet generator site which will create keys and corresponding QR codes at random.
It's generally advised that users unplug their Internet access while the keys are being generated, and that users wipe their Internet history after the keys have been created. Ideally, they'll be generated on a brand-new computer to completely avoid any malware interference. Of course, this won't be feasible for most users, but everyone should—at the very least—run a malware check on their computer before generating the keys. Print out the codes, being sure to keep track of the paper: do not let it become damaged or lost. The codes can be scanned to access additional information about the wallets, but a user must have a "live wallet" (one connected to the Internet) in order to facilitate transactions. The live wallet can be used to "sweep" the paper wallet, effectively transferring coins from the paper wallet to the live wallet.
Pros and Cons of Paper Wallets
Physical wallets were long considered one of the safest ways to store bitcoins. If properly constructed, and provided that certain precautions are taken, it will be nearly impossible for a hostile user to access your bitcoin holdings. A paper wallet is considered an extremely secure way to keep bitcoins safe from cyber-attacks, malware, etc.
But it's important to remember that it’s not the bitcoins that are being printed out like regular currency. It's the information stored in a bitcoin wallet or digital wallet that gets printed out. The data appearing on the wallet includes the public key (wallet address), which allows people to transfer money into that wallet, and the private key, which gives access to fund spending. Thus, bitcoins themselves are not stored offline—the important keys are stored offline.
This form of cold storage confers enormous security advantages. The user is more or less invulnerable from cyberattacks and malware because it is simply not possible to access a user's private key via those avenues. Of course, the safety of these physical documents cannot be entirely guaranteed either—if a would-be hacker discovers the location of your paper wallet and physically steals it, they can access your bitcoin holdings. Some users hide or disguise the paper wallet. The paper wallet should also be protected from physical damage; if the keys fade and can no longer be scanned, the user will never again be able to access the bitcoins sent to that address. Even using the incorrect type of printer (non-laser printers can allow the ink to run, for example) may damage the paper wallet.
While paper wallets offer security advantages, they also come with risks—some of them severe. Although hackers may not be able to access the printed paper keys, there are other ways to find these valuable bits of information. Printers that are connected to larger networks often store information, and malware can be surreptitiously installed to steal the keys during the generation process.
For many users, the bigger risk with a paper wallet comes down to user error. If a printer uses inexpensive ink, it may run, bleed or fade with time, rendering the wallet inaccessible. If the paper is lost, stolen, ripped or otherwise damaged, the same concerns apply. If a user misreads a key or if the wallet software no longer recognizes the private key format of the printed wallet, these also bring about problems.
More recently, investors have pointed to the use of raw private keys in paper wallets as a security and user error risk. Unencrypted private keys can easily be exposed to other users, or can accidentally be used to send bitcoins instead of receive them, particularly if users are unfamiliar with the key system.

программа bitcoin A cryptocurrency wallet stores the public and private 'keys' or 'addresses' which can be used to receive or spend the cryptocurrency. With the private key, it is possible to write in the public ledger, effectively spending the associated cryptocurrency. With the public key, it is possible for others to send currency to the wallet.бумажник bitcoin bitcoin значок bitcoin cny bitcoin demo moto bitcoin bitcoin 4000 monero xeon token ethereum bitcoin de finney ethereum cryptocurrency capitalization 5.

Like Bitcoin, Ethereum suffers from the flaw that every transaction needs to be processed by every node in the network. With Bitcoin, the size of the current blockchain rests at about 15 GB, growing by about 1 MB per hour. If the Bitcoin network were to process Visa's 2000 transactions per second, it would grow by 1 MB per three seconds (1 GB per hour, 8 TB per year). Ethereum is likely to suffer a similar growth pattern, worsened by the fact that there will be many applications on top of the Ethereum blockchain instead of just a currency as is the case with Bitcoin, but ameliorated by the fact that Ethereum full nodes need to store just the state instead of the entire blockchain history.
