What is a ‘paper wallet?’ Do I need one?

Posted by in categories: bitcoin, cryptocurrencies, economics

This post is structured as a question-&-answer. That’s because it was originally an answer at Quora, a Q&A site at which I am a Bitcoin columnist.

What is a ‘Paper Wallet’

A paper wallet is the ultimate offline wallet. It simply means that the private address to your crypto wallet is printed on paper — either as a string of characters, a QR code, or a series of seed recovery words.

If you destroy any electronic copy of your original wallet (e.g. the private keys that give you access to your wealth), then hiding this piece of paper is very similar to hiding a bar of gold. The only way that someone can steal it or know the amount it represents is to get their eyes and hands on something physical. They would need to know that you tucked it into your mattress or behind a secret panel of your cellar wall.

Lack of standards leads to new Bitcoin wallet advice

Posted by in categories: bitcoin, cryptocurrencies, economics

This update is an adaptation of my recent answer to a Quora reader who was in a panic. She asked:

What can I do after a hard drive crash?
How can I recover my cryptocurrency?

In the past, I would address the immediate problem of course. (My answer is below). But to prepare for the next unfortunate event, I recommended a wallet type based on a user’s unique experience, expertise and comfort zone. I guided the reader to weigh trade-offs of important criteria: Security, portability, convenience, and quick access to assets).

I had believed that some types of wallets were better for some individuals, but that they required a background in cryptography—or at least a discipline for meticulous practices. As CEO of the Cryptocurrency Standards Association, I had also believed that simple, unified, and popular standards would emerge very soon. I figured that this would enable users to practice safe-wallet maintenance in their own homes.

Best Bitcoin wallet: Hardware or hosted?

Posted by in categories: bitcoin, cryptocurrencies
The question asked in the title has been edited from what was asked today at Quora, the Q&A forum at which I participate as expert columnist. The original question was a bit more ambiguous: “Which is better? — a digital bitcoin wallet or a physical one?” I have included the original question, to better distinguish products and terms. All bitcoin wallets are all digital—even a paper wallet, whether a character string or a QR code. Conversely, an exchange may use “physical” wallets to host client assets, individual application wallets, or they may simply keep records of client assets that are stored, collectively, in their own master wallet. To complicate matters, Bitcoin is never really “stored” by you or an exchange service. It is stored on a public blockchain, where assets and transaction history can be traced through time by anyone. Therefore, all forms of user access are “digital”. What the reader really wants to know is “Which form of access control is better? — custodial or personal?” Type 1: Custodial Wallets are Managed by a Trusted Party They hold your assets. You view a statement balance—just like a bank account.
