1101  Local / Vos sites et projets / Re: [ANN] Coldkey™ -- Carte de stockage de bitcoin hors-ligne et sécurisée on: January 30, 2020, 07:30:18 PM
@yogg merci pour toutes ses reponses.

Mon pere a un IRM au travail et il est le seul a s'en servir (c'est pour de la recherche, pas du medical).
Je vais lui demander si il y a moyen de passer une carte dans l'IRM.
Il y a peu de chance qu'il accepte, mais bon, on sait jamais.

Si tu veux une idee de developpement de ton actitvite :

Vendre aux particuliers des hologrammes + private key qu'ils peuvent eux meme coller sur leur propres objets et loaded eux meme.

Tu aurais un holograme avec ecris "BTC holding - Secured by Coldkey" un truc argente ou dore.
Sous l'hologramme il y aurait une private key dans une petite capsule plastique ou autre systeme.
L'holograme sera plus gros que la capsule et aurait une partie autocollante qui depase de la capsule.
La capsule est collee a l'hgologramme et possede aussi une partie collante en dessous.
Tu colle le tout sur ton propre objet (cochon tirelire, memorablia, peut importe, un jeton de casino ....)
Et boom ! les gens peuvent faire leur propre "coldkey" / Satoshi Roll / digipiglet / ...... )


Pourquoi ca ?
Et bien j'aimerais bien avoir des objets crypto.
Des trucs pas trop mal, plus design que juste un paper wallet que j'imprime moi meme.
Les Satoshi rolls se vendre $80 le jeton pour 0.001 btc ( $10 de btc) soit 70$ de premium.
Les polymeris sont aussi plutot cher quand ils sont dispo et apres ils sont super cher.
Bref le collectibles sont "chers" car rares.

Moi je ne veux pas du rare, je veux du pratique.
Tes cartes sont bien !!!! elle ne sont pas trop cher.
Je me dis juste que si tu vendais ta technologie  (les hologrammes secure + private key + tracking ?)
Alors les gens pourraient trouver d'autres usages.

Alors tu en penses quoi ?


PS : meme en y reflechissant plus, tu pourrais dans l'absolue devenir un grossiste de hologramme / key et si des gens veulent faire leur propre coins / carte ils pourraient utiliser tes services.  Imagine une collaboration avec "Supreme" ou une autre marque qui veut surfer sur le BTC.

PS2 : quelque chose qui semble une heresie mais qui n'en est pas une  : avoir un double des coldkey / hologramme / ...  (que le client a, pas toi!)
Bien sure il faudrait que sur l'hologramme, et/ou sur la carte il y ait d'ecrit de manaiere visile "set 1/2".
Mais on revient a mon idee. Si des "wearable" (un porte clef par exemple, sticker au dos d'un smartphone) avec de la crypto se developpent, alors si je perd ma carte et/ou on me la vole alors je serai content de pouvoir peut etre utiliser le backup (que je garde a la maison)  et sweep les fonds sur un autre wallet.

Yaplatu aura peut être raison, mais une nouvelle campagne de signature vient de poper pour une ICO d'un truc sorti de nul part (du moins je ne connaissais pas) : DAVID CHAUM's XX Coin
Pas de posts mini, les messages en local comptent, 5 merits gagnés sur les 120 derniers jours.
Visiblement le David chaum n'est pas un débutant.

Bon alors j'ai fouille un peu.
Sur leur site web ils ont 3 gros logo : FORBES . / COINDESK  / WSJ (Wall Street Journal).
J'ai clique pour voir si oui ou non il y avait des reference a David Chaum.

So, if quantum computing is making significant breakthroughs, is there any evidence of blockchain's being prepared for this new age, and a new threat?

Aussi, point important il ne cherchent que 15 millions de USD
Ce qui est bien suffisant pour finnancer un projet.

On est loin des 2017 ou les ICO voulaient 200 millions

Bref je ne dis pas que je vais acheter, mais je me tate a peut etre postuler a la campagne.
Smart mixer paye 0.004/wk  pour 15 posts  (en fait c'est $40 donc ca varie en fonction du cours)
Le xx coins c'est 0.002btc/post/wk donc avec 20 posts ca paye pareil ou plus 

Mais si la campagne arrete apres 3 semaines... a reflechir.

J'ai lu dans la partie allemande que Yogg va faire un test  X-Ray pour voir si on peut lire le QR code sans endomager la carte.

Mais en y reflechissant, si l'hologram a un "foil" je ne pense pas que l'on puisse voir au travers.

Et pour un IRM (en plus du cout tres cher et de la difficulte d'en avoir un) je suis presque sur que l'hologramme contenant un peu de metal va etre violament defforce sous l'effet du champs magnetique.


Yogg, tu nous tiens au jus  du resultat ?

Nowaday I use Coinomi to sweep private keys. It allows you to sweep WIF, BIP38 and Mini private keys  and to be fair, I like their User Interface better.

that means you do not care about using a closed source shady wallet that may do whatever it wants in the background without you knowing it including tracking your addresses, linking them together, sending your private keys to their servers,...

O.o
Well, said like this I admit that coinomi isn't the best choice.
anyway, I would only use my smartphone just for low value (sub $500) tx / sweeping
My point was mycelium is crashing every time I want to use it.

1111  Other / Beginners & Help / Re: Accidentally sent btc to bsv address please help me on: January 28, 2020, 02:50:31 AM

If they (bittrex) import the private key that was used to generate the BSV address into a BTC wallet, they'll be able to give you a partial refund (it would be acceptable if they charged you a couple hundred bucks to pay their engineer to perform these steps).

~~
. Some exchanges do this for free, others charge a nominal fee, some won't help you at all... It's a roll of the dice, but if i were faced with this situation, at least i'd try to get my funds back.

Hey I found this online :
Source : https://bittrex.zendesk.com/hc/en-us/articles/115000961172-Bittrex-s-Deposit-Recovery-Policy


Quote
Bittrex will attempt to recover funds which fall under three scenarios.
Crosschain Deposits
Removed Wallet Token Recovery
Unsupported ERC20 Token Recovery
=> OK GOOD

Quote
Not all deposits can be recovered and the time frame of recovery is at our discretion.

Quote
Please allow up to 30 days for recovery once payment has been received and confirmed.
=> you mighgt need to pay upfront ??

Quote
Crosschain Deposit Recovery
Crosschain - A deposit of one coin to a different coins address is considered a crosschain deposit

Bittrex will only attempt to recover crosschain deposits that exceed $5000 at the time of deposit, within 7 days of the deposit and will charge a 0.1 BTC for this recovery. Recovering coins crosschain is an inherently dangerous and time consuming process.

Due to our new Crosschain Recovery System, the minimum requirement for crosschain recoveries is $3000 at the time of deposit for the following crosschain pairs:

BTC to BCH
BCH to BTC
BTC to USDT
USDT to BTC

=> they didn't list BTC to BSV !!
Also, their minimum might be  $5000  because that pair isn't listed  Shocked
And finally, they would charge 0.1BTC
Hopefully, you are in the $3000 threshold they just didn't update with the BSV possibilities

The article from their zensupport is 2 years old from  August 04, 2017 09:21  things could have changed

You know what they say, great minds think alike  Grin

Indeed, this will be one of the major cause of crypto loss in the coming yesrs.
It's interesting to think about. Go back to the early years and by far the biggest cause of bitcoin loss was being simply being careless - throwing out computers, reformatting hard drives, having no back-ups to a corrupted wallet, etc. As time goes on this kind of failure becomes rarer, as people are now fully aware of bitcoin's potential for incredible growth and it is easier to back up wallets due to seed phrases. Moving in to the future, the biggest cause of lost bitcoins is going to be people unexpectedly dying or suffering from memory loss, and having left no instructions to their next of kin about how to recover their coins.

The TV show: Oak Island, the Money pit is the greatest example. For more than 200 years people have been searching a treasure on a small island. If only the people hiding it had left a cleared message to find it back  Wink



We know people don't plan for these kinds of things as it is. Around about half of people in most developed nations don't have a will, testament, or similar document. Thousands of potentially life-saving organs go to waste every year because people haven't talked about their wishes regarding organ donation with their families. Young people in particular have the mindset of "It'll never happen to me". Why, if you haven't bothered to sort out any of that other important stuff, would you talk to your family about bitcoin? It's a flawed mindset, but a very common one.
This is True for organs, and also true for money. For example it was estimated that 14 billion of euros (deceased estate)  haven't been claimed by benefactor and are in escheat.
In 2017,  the French banking system transferred 970 million euros of money that no one has claimed and where they couldn't find benefactors. After 30 years in Limbo, the money goes back to the French budget.

I'm in the same situation as you. My wife knows how to access our wallets and where our seeds are stored. I have wondered about what should happen if we were both in a car accident together, or something similar. I've been toying with the idea of setting up a (probably 5-of-7) secret share between a couple of family members on each side and a few close friends.
Well in this case, maybe do something similar to me. ( I guess it all depends on how much you have, and how much you want to spend to secure your assets.
For example, go to Switzerland or any other neutral country. Open and buy a safe deposit box for 50 years.
In that box, put your seed on a cryptosteel or other type of medium.
Also, write on paper some explanation about being cautious and to never share the seed ....
Maybe write down the password (like 300 bits of entropy) to a "lastpass" or other similar online backup solution.
This will allow you to put data encrypted on the cloud waiting to go to your vault (if the vault isn't in the same country).
Then write a Will and state that your estate can have access to this vault. So if you and wife pass away, the next in line gets the full crypto package.
This is basically what I have done.

Or, if you prefer using a mobile wallet, you can download Mycelium and follow the instructions given on this video.

I would just say that I used to recommend Mycelium because it was one of the first wallet for smartphone and gave great options to sweep private keys.
However, on my iPhone mycelium crashed every time I want to consult past transactions.

Nowaday I use Coinomi to sweep private keys. It allows you to sweep WIF, BIP38 and Mini private keys  and to be fair, I like their User Interface better.

The technology that made you confused is the same one that provided you with solutions that enable you to reduce the risk of losing your coins.
You need to know how to improve the choice of those solutions and combine them to ensure that your currencies are not lost.
By splitting the seed into several parts, using these options will be safe.

I haven't lost any crypto because I do have contingency plan : a backed up seed out of the house.


I hope you learned an important life lesson, which is that you are not a person who can rely on your memory. If you forget where you put one such important thing in two weeks, you have a serious problem. It's lucky you didn't hide the seed the same way, obviously, you have a very large bedroom with plenty of room to hide things.
You may have mice or rats that are technologically aware and have stolen HW and taken it away (joke) Grin

Haha yeah, learned my lesson.
But it turns out, I found it last night. And it wasn't in the bedroom.
It was in my office.
I remain adamant that mice moved it out of the bedroom to the office.
Yes, over the years I started to think about back up, worst-case scenario and how to ensure that my coins aren't lost.



1) what happens if you lose your phone? (2FA? emails access? wallets on the phone ?)
Every site you enable 2FA on should give you a code at the same time, which you should write down on paper and store securely, much like you do with your seed phrase. This is your back up in case you lose your 2FA device. In terms of accounts, you should be using an open source password manager such as KeePass or Bitwarden synced across multiple devices, so if one device goes down you still have access to everything (I can't recommend LastPass as they were recently bought over by private equity firms, and history tells us that when this happens, privacy is usually compromised for the sake of profits). Wallets should obviously be password protected (not biometrics - these are easily hacked) and backed up using seed phrases.

As a matter of fact, I do have keepass, and have hidden the key, the data and the password in 3 places. But again, If i don't remeber where they are hidden, I can go the vault and get them. My weak point is to assume that the Vault is safe (has never been breached in 120 years, and the country I am is considered one of the safest).


2) what happens if your ledger or trezor is broken/stolen / or reset by someone that uses 3 wrong pin
I have both a secondary hardware wallet with the same seed on it as back up, as well as obviously my seed phrases stored securely.
YEs that is the best way, and my current set up. My Vault has a second ledger and phone


3) what happens if your house catch fire while you are away. Are you losing both your hardware and back up seed?  what about computer and USB back-up?
Off site back-ups are key. If you don't have anywhere you can trust to store your seed phrase off site, then consider splitting it as discussed below.
This is also my set up. A vault out of town.


4) what happens if you have an accident and end up in a coma. Who can access your coins?
I talk about this frequently. Some people have very poor recovery processes in place, and some have very good recovery processes which are known only to them. Both are equally as useless to someone else. Even something as simple as a blow to the head can give you memory problems. Tell someone you trust how your back up works.

Indeed, this will be one of the major cause of crypto loss in the coming yesrs. 
My wife has access to the vault in the event of life incindent. The Vault has the Seed, and the password for all my devices and accounts.


Although this site gives a good explanation of the theory behind secret sharing, the example it gives is poor at best. Splitting a 12 word phrase in to a 2-of-3 share simply by writing 8 words on each card means that if an attacker finds a single card, they only have to bruteforce 4 words to have access to your coins, which is doable with today's computers. There are other ways to split a secret where each part on its own reveals nothing, and only once combining the minimum required number of parts is the secret revealed. SLIP39, for example, describes splitting a master secret such as a seed number in to separate phrases. Ian Coleman has a tool for this here: https://iancoleman.io/slip39/. He also has other secret sharing tools, such as this one: https://iancoleman.io/shamir/. Be aware that if you are going to use such a tool, you should know how to recover the secret in such an event that the Ian Coleman site disappears, otherwise you have a single point of failure.
This on was more to share and discuss. I'm not using this tool as I have the Vault as my ultimate back up point this 3rd party access if needed (wife and / or next of kin).


Special Thanks o_e_l_e_o for your very detailed answer, It has comforted me in my choices and gave me more things to think about.

Pour les WCT, il y a 1 an (Jan 2018 - BTC a $3800) le WCT c'etait $0.75 ,   la on touche les paquerette a $0.07
LE waves etait $3.9 il y a 1an et la on est a $0.8

Je me dis que sur la prochaine bulle ca va peut etre remonter, j'ai fais une croix pour l'instant sur leur valeur.

Holding : 4500 Waves   = $3,915
              2577 WEST    = $128
