Man sollte für grössere Verkaufs-Auktionen evt. auch eine Art Escrow einführen. Der Bieter muss eine "Sicherungsleistung" von 10% (oder auch etwas weniger) vom erwarteten Verkaufserlöses deponieren. Wird der Verkauf dann (aus nicht vom Käufer zu vertretenen Gründen) nicht durchgeführt, so wird die Sicherungsleistung an den Käufer ausgezahlt. Damit können sich seriöse Verkäufer durchaus profilieren  und alle anderen.... Nur so eine Idee! ..in diesem Fall war ja nicht der Bieter das Problem ;-) Wenn ein Bieter abspringt, naja. Dann gibt es hoffendlich einen zweiten der knapp drunter war. Schwach, dass es keinen Post im Thread gab und nicht mal jetzt irgendeine Erklärung oder Entschuldigung. Shit happens. Das entscheidende ist wie damit umgegangen wird. Meine Konsequenz aus dem gebaren ist jedenfalls klar. Ente |

Bitcoin / Mining speculation / Re: Will the bitcoin arms-race end with ASICs?

ASIC's will [probably] be the end of the road, but definitely not the first generation.
They'll just follow some moore law pattern, just like CPU's do.
I think that the hashrate will grow for the next 100 years and it'll still be profitable.
Current ASIC's are like cpu's from 2000. 0.11 micron process of Avalon ASIC's is just like Pentium 3 :-)
It is going to take some time to get to 28nm. ..that's what we thought about ASICs just a year ago too ;-) Ente |

I think you can back up the seed for the device and restore that seed in a new one if it fails.
according to their bitcoin 2013 presentation the seed should be written down during first time setup, but recovery has to use software as you can't input a custom seed. I'm just not sure if using an oled was the best decision. For example, my sega gamegear still works after 20 years. Afaik the use of an oled puts a limitation on the lifespan of the device which could otherwise just last as long as it has no battery or moving parts. +1 for gamegear! "Degrading" means that the color shifts because of different degradion of the individual sub-colors. Not nice for watching movies. No problem for reading letters. It's not like the whole display will be black and unreadable. I insist on exporting/printing/backupping the individual, plain privkeys though. Who knows if there are new trezor' and compatible software in x years. But as long as Bitcoin exists, I will be able to do something with plain private keys. Ente |

I stopped reading after the first page.
Leave Bitcoin, as the protocol, as it is.
Write a new client software which implements GAAP.
Solve the trust issue in not having a full copy of the blockchain.
Profit.
Alternatively:
Create a fork which is lightweight and GAAP compatible.
I would suggest to try #1.

I don't see where Bitcoin is any different to money or apples. I am not allowed to steal neither of them.
It's impossible to steal information, only to copy it. Unless you take away one's ability to access that information, I can't see it as stealing. Bitcoins are public information, because they are stored on the blockchain. Maybe you want to protect private keys with intellectual property laws, but that would require some kind of proof that you were the only one to have access to them in the first place. I don't see any other way to make "bitcoin theft" illegal. Aah, I see where you are getting at! Yes, makes sense. Not sure if "sense" applies to laws, though ;-) Ente |

Good work tracking them down, Sebastian!
There are a lot of projects based on BKKCoins work. I would like to hear from the devs if they have anything in mind if/how to support BKKCoins for his work? Maybe "x % of the sales" or "xy BTC flat" or "z days burn-in test on his address" or the like?
BKKCoins is thinking about dropping all "DRM" and "forced fee in firmware", and releasing everything completely free, and hoping he'll get some voluntary support.
Let's show how awesome this Bitcoin community really is, and help him out, for all the weeks, months of fulltime-work he invests!

I would like this too... i see that many assemblers already have a fee included thought as a fee for BKKCoins... i hope all are doing this... its a small fee for buyers only but a nice compensation for BKKCoins. That's good to hear! Care to include that info into the list? Developers, state your position! This is a good opportunity for you to gain support! :-) Ente |

My current view is that Bitcoin is and will forever been public property and anybody who is able to make the transfers (by being in possession of the private keys) is allowed to do so.
Unless you scam people in making transactions while making false promises or you break the law while obtaining the private keys, I don't think there is any legal system protecting you against somebody else tranfering all the bitcoin to another address. Which effectively makes it legal to take any bitcoins you want as long as you are able.
The only way I see around this is having an international institution like the U.N. attaching your name to a private key.
Is there anybody who can provide a source for a single conviction or legal action against a person that comitted a Bitcoin "heist" or "theft" (not "scam")?
Uhm.. "If someone has your private key or your Bitcoins, and didn't do anything illegal, it' not illegal". Wut? An example would help me here.. I don't see where Bitcoin is any different to money or apples. I am not allowed to steal neither of them. Ente |

I would REALLY love it if you can use the device to sign messages as well! I could use it to verify my identity online securely as well. Like a secure pgp key but using Bitcoin private keys to sign the message.
so now all a thieves has to do is find someone with a huge bitcoin wallet. sniff out their ip, reverse lookup ther vpn to find there real address, narrow down your location, come and take you hostage at gun point and force you to give over your "hardware wallet" usb. this makes bitcoin no different than real money now in my opinion. 1) You can't just find out the IP of some wallet (without asthonishing effort). You can't reverse-lookup the ip to a home adress (without the law on your side). 2) Explain me how you would give up your hardware wallet at gunpoint, but would refuse to give up your software wallet at gunpoint. As he already knows the balance you have. The hardware thingie protects you from malicious software, no matter if its a trojan horse on your own computer, or a non-trusted, maybe public computer. That's all. For everything else there are different, better solutions. Ente |

Bitcoin / Project Development / Re: [BETA]Bitfinex.com first Bitcoin P2P lending platform for leverage trading
|
on: June 02, 2013, 11:11:12 AM

I didn't read through the whole thread, but want to give feedback on Bitfinex.
1) MtGox not connected at the moment? This one hit me out of nowhere. It seems it was stated in forum threads, but no user mail was sent out. This is one of the main reasons I will not use Bitfinex in the future.
2) I closed my long position today. So I am *forced* to sell the whole position at market rate? This is desastrous. I had enough USD to cover the swap. When I closed the position, I now have my gains in USD and still have the USD I meant to use for paying the swap. I hoped to have no USD left and my gains in BTC. Now I am stuck with a ton of USD, but with no volume left to convert to BTC to get out again. Thanks, non-connected MtGox. This is costing me a lot of money for no reason.
3) When selling a part of my position, the lending with the shortest left runtime is closed. Even when it has the lowest swap rate, which most often is the case. I can not define which lending to be closed. This is annoying and costly.
4) To get around 3), I tried to open a new lending, with for example a runtime of only 2 days. This one, as the shortest running lending, would be closed then. Annoying time-consuming work-around. But I can't even get a lending with a runtime I define. It will be 2 days lending *minimum*, but often I will end up with longer runtime offerings. I don't even have to mention that I ended up paying more swap than needed, do I?
5) Please, make the huge tables able to sort. Like "sort by remaining runtime". This would help a lot to not have lendings closed unexpectedly, with large tables.
6) With every close of a lending, the whole page refreshes. This makes closing many lendings very timeconsuming and annoying.
7) The overall speed seems to be low. Like, I suspect, one trade/lend/position after another, each at least one, two seconds. This is no fun, but bearable.
So, I guess all this sounds pretty harsh. I am grateful for the service you provide, grateful you weren't hacked in the meantime, and got out with some profit (once my withdrawal clears). I will get out with a good chunk less in profits because of mechanisms, bugs, missing features, undocumented behavior though.
Edit:
This all does sound pretty unfriendly. Sorry for that.
I got some gray hair in this margin trading episode. Not because of Bitfinex, but because being all new to this. I started with too much funds, not knowing enough about the general setup of margin trading, and am not a good trader to begin with. I am glad to close my positions, holding long-term and 'forgetting' about it will be my strategy again.
A big thank you to Raphael and 'myself' and all others for the great work you do. The top priority is security. The second priority is being in contact with the community. The third priority is enhancing the platform. You do this exactly right!
Cheers!

Anyone know how the chips are supplied in reel or tray? In avalon specs do not mention this  I'm sure it won't be in a reel; most likely a tray, The samples might be in a tube. I found these pictures from asicminer asic's. https://bitcointalk.org/index.php?topic=99497.msg2268332#msg2268332 Bitfountain uses TMSC foundry too. And friedcat told me "Our chips use 6mmx6mm QFN40 package." while avalons are 7x7mm. So i think its possible that all chips come in tubes. I mean the tubes could easily be put into a packet and shipped. And i think the reason why the sample chips per batch are exactly 30 are that the tubes contain 30 chips... at least AM's tubes contained 30 too. I have to know too how avalon ships because i have to buy the needed packaging for my groupbuy... Good work, sherlock! :-) Ente |

Come on, people! This is the first time in history that we can buy more ram than needed for small money! The cheapest brand-ram is fine, a lot of cheap ram beats little but fast/expensive ram easily.
Ente
If you live in the wealthier part of this world you might be absolutely right. But a majority of the world population lives in poverty. One of the real use cases of Bitcoins is to transfer value from one country to another country. Remittances by Moneygram or Western Union are extremely expensive for those immigrants who will send money back home to support their families. Having a secure wallet at lowest possible cost is also for these people important. I hear you. And I will take my part in "enabling" those parts, all parts of the world to use technology and Bitcoin to change for the better. For now, I don't see Bitcoin and the whole ecosystem around Bitcoin ready for this. For the great picture, I see Bitcoin, Armory, cryptocurrency in beta, maybe even alpha status. Getting to a stable, useable, fair and sound system is our job. Like, the job of everybody in this thread. And until Armory is a 'global player' (whatever this may mean and bring) and comes preinstalled on every 5$ mobilephone, I encourage everyone here to invest in (cheap) ram. For alpha-testing, and, together, getting there! :-) Ente |

I was going to install armory some time ago, but whenever I go back at the site, I see this warning message about 6 GB of RAM and it stops me from downloading and finally starting using this software. If I have 4 GB RAM, it won't even start, eh? Should I try installing now or just sit back and whait until this will be fixed? Thanks for answers.
I used to have 4 GB of RAM and Armory took forever to load. The reason for this is that it would start using swap space which is much slower than main memory. So yeah, I would hold off for now. Etotheipi should have an update soon that will trade the need for memory for disk space. 4gb was just fine here, with Armory munching away around 2.5gb. No swapping as I deactivated it. Linux, that is, here. I got me 8gb more, just for Armory :-) (Just like Bitcoin was the main reason for a smartphone, pack then) Come on, people! This is the first time in history that we can buy more ram than needed for small money! The cheapest brand-ram is fine, a lot of cheap ram beats little but fast/expensive ram easily. Ente |

Nice work Ente... been waiting on someone with the right math skills to do this.
What specs for the heat sink do you think will work?
Ah, that stuff is easy once you figure it out! :-) "0.5K/W" means, for example, that for each W[att] you throw at it, you have a K[temperature] difference of 5 degree. Like a 30 watt CPU cooled with a 5K/W heatsink would be 30*0.5 = 15 degree above the air temperature. You add up all thermal resistances between the heat producer (CPU or ASIC core) and the surrounding (air). This is the thermal resistance of the cooling system. Here we are at around 7K/W combined. Interestingly, the difference between air- and watercooling is neglicible, at an additional 0.25 K only. This 7K/W is for each chip, it doesn't matter that we have 16 chips combined (as long as the heatsink covers the whole 10x10cm, doh!). This means, at 2 watts, that the silicon will be 14 degree warmer than ambient. Best case. Calculate 20 degree for some margin. So, air or water? Depends on your setup. If it's just a few chips, you won't have problems with air. As soon as your room would warm up, like, in summer with a thousand chips, you might prefer watercooling. Not because it cools better (it does not), but because you can cool the warm water somewhere else than where the chips are. Like having the miners inside and the radiator outside. Or warming your pool with it (use two watersystemns for that!). Air? Any regular heatsink with a regular, slow spinning fan should be more than enough. A 1K/W heatsink isn't anything special, and that's with no fan! So, basically, as long as you have any aluminum piece with fins on it and have a little air blowing at it too, everything is sweet! :-) In hindsight the whole calculation isn't really necessary. I didn't expect it to work out that nicely. Homework: Calculate similar systems with a 90w CPU (20x20mm), regular thermal compound and a bad/calm 0.5K/W heatsink. Max allowed CPU temperature is 70°C. How hot may the air in summer be at maximum, before the CPU starts cycling down its speed? edit: Homework #2: What performance must a better heatsink have at least to work up to 30°C with the same CPU? Ente Hi! schicke Aufstellung, vielen Dank. Nur eine kleine Korrektur: 0.5K/W" means, for example, that for each W[att] you throw at it, you have a K[temperature] difference of 5 degree. Like a 30 watt CPU cooled with a 5K/W heatsink would be 30*0.5 = 15 degree above the air temperature. Die jeweils fett gedruckten 5 sollten 0.5 sein, oder? Ist so etwas verwirrend für jemanden, der sich zum ersten mal da reindenkt... Gruß, Sophokles Tatsächlich, gut aufgepasst! :-) I started with a 5K/W example. This is such a bad heatsink that it results in odd numbers. When changing to 0.5K/W I didn't edit all numbers. Thanks for the note! Also, the answer to your homework: Don't cheat, calculate it by yourself! :-P --->#1: This bad heatsink with such a powerful CPU would only work up to 11°C! *giggle* <--- --->#2: For that CPU you would need a 0.28K/W or better (=smaller number) heatsink <--- Ente |
