Bitcoin Q&A: Key Storage Best Practices

Ғылым және технология

What is a hierarchical deterministic (HD) wallet? How are paper wallets different from hardware wallets? Which of the Bitcoin wallets and / or clients (mobile, desktop, hardware) is best for storing coins? Are hardware wallets with Bluetooth secure? Regarding desktop wallets, what happens if your hard drive fails? Should you use different tools for storage of keys versus spending? Should you encrypt a text file for cold storage of keys?

    16:47 Nice to have my completely ignorant thoughts validated despite misinformation everywhere. It makes no sense to obfuscate a secure backup; that's just banking on your security not being good enough. If your primary security is good enough, then having a second layer of encryption only serves to make your own recovery harder.

    @@stephenkamenar no, but you can still send the coins that are stored on a paper wallet, and a phone that can send coins is not truly offline, so is inherently less safe than a fully offline wallet. But I like your idea, just think an effectively broken phone is harder to achieve and then becomes an offline wallet, just like a paper wallet. I think we need phones like the laptops that you can get with hardware on off switches for wifi, mic and camera, so you can be sure they are powered off while the phone is on. There is one company that sells laptops like that, just forgot the name..

    I know this video is old but maybe someone could help answer a simple question. I want to use the 25th word or "passphrase" option on my HW wallet so I can link that with the secret pin code for security reasons. Is using a 25th password where the password is "weak" somehow less safe than just the standard 24 word seed? In other words... Since I'm doing this for plausible deniability I'm not concerned about anyone getting my 24 words. Adding thr 25th word is solely for the feature of the hidden accounts associated with it. In this scenario, is choosing a 25th word that is weak, somehow less secure overall than the standard 24 word phrase? Sorry I know this sounds silly.

    The obvious reality that hardware wallets will not remain reliable over time (because of changes in business and logistical practices of the manufacturer - and due to business failures, mergers, etc) frankly never occurred to me before, and this makes hardware wallets an *absolute* nonstarter for the average human being. The idea that Joe and Jane 6 pack will accept going to the trouble of periodically (in a very complex and risky process) shifting to an entirely new hardware wallet to keep their vital savings safe, is simply absurd. For widespread adoption to succeed, the average human being needs to be able to put their keys on a hardware wallet and be *absolutely* assured that they can go to that wallet 100 years later and withdraw their funds easily and successfully. Until that guarantee is in place, any sane lay consumer will choose an insured custody provider like Coinbase, and not a hardware wallet. Those of you in cryptocurrency tech need to put yourselves in the shoes of the lay person and do serious work to quickly solve this problem, or the vision of a peer to peer, uncensored, democratic economic system will never happen.
