Is the Raspberry Pi Zero powerful enough to generate a Bitcoin wallet address using Bitaddress.org?
I would like to create an offline wallet using an offline version of bitaddress.org (https://github.com/pointbiz/bitaddress.org) on a Raspberry Pi zero. Just wondering if it will be able to handle it? Has anybody done this? Thanks!
Is there a way to generate a bitcoin paper wallet that does not look so obviously like a bitcoin paper wallet?
Every single paper wallet I've come across are designed to look very much like a paper wallet. It has instructions everywhere on what it is, how it works, etc. I feel this is not very good for security, because if someone gets ahold of the paper wallet, the instructions tell you exactly what it is. On the other hand, if you had a "stealth" paper wallet that looked like a random printed off email, the wrong person is not going to know it contains a bitcoin private key. Is there such a way to generate a stealth paper wallet? If not, I should be able to theoretically make one myself. How can I easily generate a bitcoin wallet public/private key for printing a paper wallet?
Some newbie questions about Trezor device and bitcoin wallets
Greetings I have never owned bitcoin before, but I studied how it works, so I think I have some understanding. I also studied options and it seems hardware wallet is the way to go for safety reasons. So, question number One, am I correct that: Unlike a bank account, where you keep one account usually, with bitcoin you keep generating new addresses, so if you own 1 bitcoin, you don't store it on one address, rather, you own many addresses, each containing part of your bitcoin, and when you spend, you just expend some of the addresses and throw them away, and when you receive, you generate new addresses for every transaction, so you accumulate these addresses that each are like a banknote of sorts, each having their own nominal value, and then you spend those banknotes and never use those addresses again. Right? Question number Two, am I correct that: All the addresses are generated from a certain big number, "master key" of sorts, which is private to me, which can be written in a form of "seed" which is what the device will give me when initialized, which is what I can use to recover my master key if I lose or break the device? Question number Three, who does the address generation for bitcoin wallets for new incoming transactions? I assume it's the online wallet Trezor uses, right? So the device does not store any addresses of bitcoin wallets, right? It only stores my master key? Assuming all are correct, can you please explain, in simpliest terms, how do I restore these addresses themselves, should Trezor online wallet be unavailable? I mean, it's hardly a possibility, but assume I have my seed, or even my Trezor device, but Trezor online wallet is unavailable. Assume I made hundreds of bitcoin transactions and my bitcoin is stored in hundreds of small pieces on different addresses. How do I recover all those? How do I know when to stop, when I have recovered them all? Assuming I don't know the amount I totally own by heart, so I cannot know when to stop (When I found all my bitcoin)? I mean, it's unlimited, right, the amount of bitcoin addresses that can be generated from my "master key" of my Trezor? So how do I know which of them contain bitcoin? Like, say I have used 200 of them and 100 of them still contain bitcoins, and I lose the device, and have to restore from seed, how does it know that it has to generate only those 200, like, how does it know it doesnt have to generate more addresses, maybe those other addresses contain some bitcoin on them too? Or does it, generate them always in the same order, so if it sees only blank unused addresses, it assumes it's time to stop? Like, if address 0-200 are all used but 200-300 are all unused still, it assumes it's fine to stop checking? Also, on an unrelated note, how can I be sure I made no mistake in recording the seed? Can I just wipe the device and restore it from seed right after initializing it and receiving a small bitcoin transaction, to test it and be sure that I can recover my bitcoin in case I lose it? Is the device unlimited in terms of how many times it can be wiped and restored? Thanks in advance!
What's Bitcoin Core behavior after running out of the 999 receiving and change addresses it generates when creating a wallet?
Does it starts reusing them from the beginning again? Or does it keeps generating addresses 1000, 1001, 1002, etc? If the latter, what are the implications for when you restore from your hdseed? Do you need to take extra steps to make your wallet aware of beyond 999 addresses? What's the Electrum behavior for this? How many addresses it generates by default?
A humble request for feedback on a potential new use case for Bitcoin wallets: To verify the authenticity and supply of physical goods
I'm working on an ecommerce website that uses Bitcoin address/key pairs to verify the authenticity and supply of the clothing it produces and sells. When purchasing an item, the Customer:
Generates a Bitcoin wallet (secures their private key)
Submits their public address to the website
Their public address is printed on their clothing and posted to a publicly displayed table on the website
The idea is Customers can verify their item is accounted for in the total supply and prove it's authentic by signing a message with their private key. For reference, the website (pre-MVP) visualizes the high-level process: https://scarce.city/ And the whitepaper (forgive the slight parody) addresses logistical details: https://scarce.city/whitepape I'm hoping savvy Bitcoiners can poke holes in the process. Any faults I'm not seeing? All feedback is appreciated!
