hehe  da war ich irgendwie noch nicht ganz wach als ich den Post bei ''Biete'' eingestellt habe. Danke für die alternativen Vorschläge! Der Unterschied zwischen dem Entropy und der Selbstbauvariante ist soweit ich das verstanden habe: Selbstbau: Zufallszahlen werden aus einem Signalrauschen erzeugt Entropy: Zufallszahlen werden aus dem Initialwert eines SRAM erzeugt Schade, dass Mycelium die Teile nicht mehr als Plug&Play Lösung verkauft...  |

IMHO if you create private keys for others you better not fuck this up. So for max security I would use a true rng to generate those.
So whith mycelium entropy you don't have to worry about the randomness of your rng.

isn't it just as easy to save the bitaddress.org webpage to your desktop, sign offline, and then print via non wireless connection? Best practise states that creation of private keys are done on a computer that has never and will never, see any network during its life as a Keymaker. This also goes for the printer used to print out the keys. Viz This is correct. If you want to be "safe" you can get a cheap or old laptop, remove any wifi cards from it or network functionality (as in remove the actual wifi card). Wipe the hard drive or put in a fresh one. You have a few options to either download and install an offline program like bitaddress (via a usb stick) , or run a program like bitaddress off a new or clean usb stick. Find and buy a laser printer with no network functionality, meaning no wifi, no network cable, - usb only. (wasn't as easy as you'd think with all of todays wireless crap built in , out there) Connect your non networked laser printer via usb to your "air gapped" laptop (no network connections to the internet or otherwise) Run the program of your choice, and send the output to your laser printer. Now you have generated an offline paper wallet which you can laminate if you wish or store safely as cold storage. If anyone finds that paper, which will in most circumstances have the private key on it, which is usually next to the QR code and public key, they can simply use it to claim the funds. So keep this in a secure place you wouldn't want anyone to find. There are many other ways to accomplish the end result , this is simply one of them. I hope that may help someone looking to set something like this up in a secure manner. thanks! Yep did exactly that with a new laptop and printer just for offline wallets. But did not physically remove the wifi card. I disabled the wifi from connecting to anything at all. Also BIP encrypted your wallet so in case anyone does find it they will have a hard time figuring out the password! Even if you generate your private keys offline it is insecure if you use an unreliable rng. So you need true random numbers for max security which is where mycelium entropy kicks in. The Initial state of SRAM cells when switched on is truly random. Another truly random process for example is atomic radiation. |

Hallo Leute,
bin zur Zeit auf der Suche nach einem Mycelium entropy. Falls jemand einen verkaufen würde einfach PM an mich. Danke

Message signing is done with private and public keys. Addresses are neither of those; the are representations of an output script. You can't sign with an output script. Signing a message with an address should never have been called that in the first place; the address is not a public key so it can't be used to sign or verify anything. So no, it is technically impossible because it is impossible to know what script you want a public key to map to to get the address a message was signed with.
Thank you for your fast reply. Yeah I know that public key is not the public adress. Nevertheless with old adress format it is possible to 'sign' a message but with segwit adress it's not. Why is that? |

How do you plan to generate the private keys?
If you like/need I can lend you a mycelium entropy.
Awesome!  I'm happy there is trust but I still think I'll speak with you MJ because things can always go wrong. How long should we make this inusrance policy? 1 month? two? And Lincoln! Awesome, yes please! I'd pay rent on it in notes  Deal!  For all people who don't know what a mycelium entropy is: https://mycelium.com/mycelium-entropy.htmlIt is a device for generating true random numbers in a reliable way using SRAM. This is very important for secure private keys. Unfortunatly you can't buy this product any more. I wonder why they no longer sell this  Imho back at the time 2013(?) this device didn't sell very well so after batch 1 they decided to stop production. In addition there some important people left the company. |

Hi there,
I was wondering the othe day when will it possible to sign a message when using a segwit adress. It is an important feature to me and I still didn't transfer most of my funds to a segwit adress because segwit adresses lack this feature.
Is there a timeline available when a standard for signing with segwit wil be available or is it technical impossible to do?

Oh damn. Yeah I meant 0.03 for #5 |

Kann mir gut vorstellen, dass Jihan&Co viel Kohle mit dem stetigen Verkauf von Segwit Futures gemacht hat. Wie zentral gesteuert das ganze nach dem Fork weiter gegangen wäre sieht man daran wieviel Leute gereicht haben um das ganze abzublasen. Lächerlich. |

Gelöst ist damit trotzdem nichts, nur vertagt, der Mempool war zum letzten mal am 26.10. leer, davor am 28.09. und es wird nicht besser werden. Das sieht selbst ein Blinder mit Filzbrille: https://blockchain.info/de/charts/mempool-size?timespan=60daysEin Pyrrhussieg - wer nicht die Möglichkeit hat, über einen Accelerator seine Transaktionen zu priorisieren, wird immer tiefer in die Tasche greifen müssen. Wir schieben schon jetzt über die BTC Chain nur noch das, was wir per Accelerator mit 0.0001 BTC/KB durch bekommen. Der Rest läuft über... drei mal dürft ihr raten und der Groschen wird in Zukunft auch noch bei Anderen fallen... Wenn du in der Erhöhung der Blocksize die Skalierungslösung siehst tausche alle deine bitcoins in bcash. Ganz einfach. Wir werden sehen wie gut diese Lösung sich in Zukunft verhält. |

aber ich lese daraus das es nichts mit ETH zu tun hat, sondern mit dem Multi Sign Wallet von Parity.. Das Problem: Die Multi-Signatur-Funktionalität der Anwendung hängt der Mitteilung nach von einer Code-Bibliothek ab, die ihrerseits als Multi-Signatur-Kontrakt auf der Ethereum-Blockchain abgelegt wurde. Offenbar war es durch schlampige Umsetzung möglich, dass auch Unbefugte ohne größeren Aufwand die Kontrolle über diesen Kontrakt ergreifen. Konkret konnte man diesen Smart Contract wohl in eine normale Multig-Sig-Wallet umwandeln und sich selber zu deren Besitzer ernennen. Ethereum ermöglicht aber erst diese Art von dumb contracts. Naja dann gibt es halt mal wieder einen rollback der chain. Code is the law. Until it's not! alles klar... |
