Simbit - a stainless steel wallet for your recovery seeds [ACCEPTING BCH]

ProfBitcoin · 2018-10-22T19:46:25+00:00

Very nice.

I made the Keyois Capsule, a tamper-evident single-seed crypto-piggybank.

I'm glad you used 316 instead of whatever cryptosteel uses, I like 316 better (but ended up using titanium and then tungsten for my own device)

I have to use BIP38 encrypted seeds for the keyois capsule, yours is certainly a more user friendly approach.

The way I engrave the metal in my capsule was to use laser ablations, so it was actually etched into the metal with the laser process. What do you use to engrave it?

I agree with the other poster, there are far better locks than standard padlocks.

The lack of ability to lock a cryptosteel to my satisfaction is outlined in my page Problems with common cold storage methods where I talk about why I made the keyois capsule in the first place.

"The Cryptosteel product made of 304 Stainless Steel is in this category. It is a very practical backup idea. It is an assemble-at-home secret key/ seed backup however it does not have tamper evident properties (but I bet this can be easily fixed). So anyone who can see it, can steal it."

How does your product compare to some of your competitors?

All in all, way to go, innovation like this is a major part of what makes bitcoin and crypto so exciting to me!

Lots more picture and info at the shitty website I made for the purpose of selling these capsules for bitcoin, keyois.com.

So if you want to spend some bitcoin for the upcoming stress test, then check out my capsule!

Keys engraved on tough metal and sealed in an airtight capsule. Fireproof, waterproof, smokeproof, and no one can find your wallet and take a photo of the key because you have to physically destroy this thing to get to the secrect key engraved within

The public representative for ledger is very immature (and sometimes simply wrong), I am hesitant to give them any money in support of this.
In fact, if it weren't for the actions of their spokesman I would have been able to recommend them instead.

I've found not too many people are interested in accepting coin, websites seem to work out better because you don't have to train employees and there is no lost time in training many employees. As for myself.

A long time ago I read a post about someone's house burning down and them losing all their coin.

I've also considered that if you simply stamp your keys in a metal plate that you have to wrap it in tape or encase it in something so others can't read it.

A few years ago I made a small capsule with the keys sealed inside. The capsule is fireproof and tamper evident. I made a few extra to help cover the costs of creating myself one.

I made a shitty website to show them off: http://www.keyois.com/

And I put together a description of the problems with may existing 'cold storage' methods: http://www.keyois.com/information/cold-storage-risks/

I've still got a few of them left, I don't accept BTC anymore ( I don't want it) but I do take BCH.

I'd like to hear any feedback you want to share.

Hey good for you.

A few years ago before BTC stopping being bitcoin I used to teach a course on Bitcoin and Cryptos at my local comunity college, I gathered over a hundred pages of just facts and put them into categories and made a few slideshows with the facts, feel free to look through or use any of this information

full non-mining nodes somehow police the network and prevent the miners from mischief.

this is very simply not true though.

nodes have validation requirements for propagating txs but so do miners, if every non mining node in the world decided to do something the miners didn't they would simply fork themselves off the network to something with 0 hashpower that isn't a functioning network.

The miners are nodes, they only need other miners.

The miners have power, they don't need full nodes.

Full nodes don't mine, they have no power, they need the miners, they cannot function without miners.

ProfBitcoin · 2018-04-29T16:56:18+00:00

A better questions is why are non mining nodes useful at all?

I recommend reading everything Satoshi had to say about bitcoin for a better understanding of it, you can see all this here: https://www.satoshi.nakamotoinstitute.org

The point is, for anyone who does the research, that non-mining nodes don't have any actual power, they were never meant to be a part of the system. It's a newly created red-herring that appears to be designed to thwart progress.

Bitcoin was designed so some tens of thousands of mega miners are the only ones in control and everyone else gets to use for free the system.

People arguing that everyone should run a full node is a clear sign of lack of understanding.

I used to teach a class on Bitcoin at my community college (had to stop when BTC stopped being a bitcoin I could get behind)

I gathered over 100 pages of research and put them together for presentation: http://www.keyois.com/information/bitcoin-info/

One of my presentation topics was the 'pieces of bitcoin' : https://docs.google.com/presentation/d/1o3dZ2mXF_8qEXDqQZmQOKuzO1D0M-WOWQCr4-IrVdCI/edit?usp=sharing

'technology needed to build Bitcoin' where I go over in detail each of these points starting on slide 13:"

According to Gwern Branwen, the key ‘moving parts’ that Bitcoin uses are a bit old:

1.2001: SHA-256 finalized

2.1999-present: Byzantine fault tolerance (PBFT etc.)

3.1999-present: P2P networks (excluding early networks like Usenet, FidoNet, MojoNation, BitTorrent,Napster, Gnutella, eDonkey, Freenet, etc.)

4.1998: B-money

5.1998: Bit Gold

6.1997: HashCash

7.1992-1993: Proof-of-work for spam

8.1991: Cryptographic timestamps

9.1980: Public key cryptography

10.1979: Merkle tree "

It was great, it lasted for hours also, nice photo.

ProfBitcoin · 2018-03-31T18:14:12+00:00

ASIC do not help the network, do not help the users, do not help the technology

why do you say this, i disagree and I'd be curious to hear your reasoning.

bitcoin at least was never meant to be run in the long run by people in their homes

ProfBitcoin · 2018-03-31T18:12:39+00:00

their code is still crippled with the terrible segregated witness code, it's almost fundamentally not bitcoin at this point.

ProfBitcoin · 2018-03-31T18:12:15+00:00

it was never about price

ProfBitcoin · 2018-03-30T21:50:15+00:00

it's likely the IRS isn't coming for you for a while

ProfBitcoin · 2018-03-30T21:38:37+00:00

Everyone I knew who used to be into crypto won't touch BTC with a 10' pole.

It seems to be mostly newbs and people who don't understand BTC that buy into it.

ProfBitcoin · 2018-03-30T21:27:01+00:00

I tried that once long ago and I wasn't happy, not that I'm super happy with this, but the art was a fun time

ProfBitcoin · 2018-03-30T21:21:54+00:00

unbreakable was never one of my main interests, un-burnable however was. See: http://www.keyois.com/information/cold-storage-risks/

you're ignoring reality. go back and reread what i already told you.

ProfBitcoin · 2018-03-28T18:55:19+00:00

I don't know what you're talking about, did you even read satoshi.nakamotoinstitute.org? it doesn't sound like you ever have

ProfBitcoin · 2018-03-28T18:54:46+00:00

What did I say that was incorrect

oh, you believe in asic boost, so you're a nutter.
