21  Economy / Service Discussion / Mtgox SEPA withdraws status? on: July 16, 2013, 07:28:35 AM
USD ones are locked, what about the EUR ones? Locked as well, from what i gather in the threads.
Anyone can confirm it?

Thanks.
22  Economy / Auctions / 1 x Avalon (3 Modules), shipped to you Monday 24 on: June 17, 2013, 11:00:00 AM
I received the tracking for my lot of Avalons and i still have one i can sell.
I will pay the shipping to your location and i will ship the unit to you next monday (i'm too busy before that, but you will receive a sealed unit, i will not mine with your avalon [if you ask for it i will connect and mine for you from when i receive it and monday when i ship it to you]).

Starting price is 150BTC, auctions ends friday 21 @ 20:00 GMT time.

Escrow is discouraged (i hate using escrows) but can be John K.

24  Bitcoin / Hardware / Dreaming about open sourcing an ASIC chip on: May 11, 2013, 10:33:21 AM
Let's suppose that i get rich one day. (This is an hypothetical me, i'm nowhere near that, so don't pm me trying to scam me). Let's say that i have 2M$ (20kBTC). I have all invested into Bitcoin (because i'm crazy) and i want the Bitcoin network to be as strong as possible. I decide that i need to create and to open source to the community a low-nm ASIC chip. I'm ready to invest up to 1M$ into it.

I do that for free, because thanks to Bitcoin i'm rich and i want to give it back to the community.

Do you think that this will actually happen?
If you own that much, why don't you do it?
Is 1M$ nothing in this business?
25  Other / Off-topic / About the recent OVH hack (that affected bitcoin-central, instawallet, slush') on: April 30, 2013, 10:20:32 PM
This is the official update from ovh: http://forum.ovh.co.uk/showthread.php?t=6592

Quote
On April 26th, we detected an internal problem with the generation of the 21 characters. 2 out of the 3 random functions that we use in the code were not generating an authentic random sequence. It was possible to request a password change for a customer ID,
and then find the "unique" URL emailed to the customer by brute force. The problem was found by an internal developer on April 26th at 11:03:14 and it was fixed at 12:54:13. The cause of the problem was linked to the rand function used in this part of the code. It was not patched to the same extent as the rest of the code at the time of activating the script execution cache. We have replaced the old function of 3 sequences to generate 21 characters with 2 authentic random functions to generate 64 characters.

We then ran searches on our databases to verify whether the loophole had been exploited and if so, when. We tracked the log of password changes for your IDs for the last 3 years. We actually have authorisation from the CNIL (the French data protection authority) to archive and exploit all our back office logs for the last 10 years, precisely for this type of situation.

We detected three password changes carried out by brute force on 3 customers IDs with active services. These 3 cases involved an attack aimed at the "bitcoin" community that uses OVH services. The hacker seems to have found the loophole on April 23rd at
22:00 and ran a significant number of tests to develop their tactics over a period of 1 hour. At 23:00 it had been perfected and the 1st ID was hacked, followed by the other 2 the next day (all from the "bitcoin community"). We have been in contact with these customers but the quality of the exchanges prevented us from obtaining sufficient information to identify this loophole. Thanks to our internal developers, we have fixed the problem in a totally independent manner. Only then did we begin to make the connection between the loophole that we had just fixed annd these 3 customers. We have certainly learnt a lesson on how to communicate with clients in this type of situation.

If you still have 7 characters of entropy, that's 60^7 combinations. If the attacker hacked the account in one hour (as they claim), how did the attacker sent 777600000 requests per second for one hour without them noticing? One billion requests per second, that's not something you usually handle. Nor your servers, you would crash anytime.

Something is missing from this story, or i'm blinded and i'm missing something myself.
26  Bitcoin / Development & Technical Discussion / Given a peer ip addr, can i force it to use a forked blockchain silently? on: April 22, 2013, 11:41:41 AM
Just a guess - suppose that you want to convince a bitcoin client that the network confirmed a transaction that didn't occur - would it be possible to fulfill the client with loads of connections from fake network peers, specifically developed to broadcast and confirm such a fake transaction?
27  Economy / Computer hardware / [WTS] Shares/Hardware 5 x Avalon Batch 2 on: April 20, 2013, 01:24:54 PM
I have a preorder from Avalon and i want to stop thinking about it, so i'm offering to mine with these units in your behalf. If you want to get into ASIC mining with the second batch of avalon, this is a good chance. The units should be shipping during these very days.

The price is 200BTC/unit, not negotiable. If you pay more than 67 BTC you will own a module and will have it shipped, if you pay more than 200 BTC you will own an avalon and have it shipped too. Well, only if you wish to.
I will mine from a secure location (not a datacenter, not my home).
I will be free to refund everyone at any given time and close the deal this way. For example, if i receive only a few requests for a few shares, i will refund everyone and save me from the mess of handling this.
I will take a 3% fee for handling the operations and deduce the electric costs from the payouts.

If you want to own a part of these Avalons, send multiples of 0.5 BTC to 1A8fvPz1MhqSJ2oYbQcYhoLko5UDAmpnNe Shares sold out, please don't send any money. 3BTC ~= 1GH.
You have to send them from an address you will be able to receive in the future, every single payout will be given only to the address that sent the money in first instance. If you plan to communicate with me at a later time, you will also need the private key of that address, to sign the messages. If you want to purchase a whole avalon and have it shipped to your home, you will need to do that with a signed message. If you don't know how to sign a message from the sending address, maybe this service isn't for you.

Example: you want to have 1/10th of an Avalon (~6.5GH), you send 20 BTC to the given address. You will receive the payouts to the address you sent the money from.

To make this more real, here are some photos of the place that will house the Avalons.
I have a very good power grid (no outages in years) and a very stable connection, via 3G, fiber or xdsl dosen't arrive at the place i will be mining.

28  Economy / Economics / My toughs about the current exchange problem on: April 14, 2013, 12:47:43 PM
I just inserted this as a reddit post, but since that it's my first time as a reddit user, i will crosspost it here. Just to be sure that i spent time to write something people will read Wink

http://www.reddit.com/r/Bitcoin/comments/1cbm4q/my_toughs_about_the_current_exchange_problem/

Quote
  • we can't create a distributed exchange, so we need a distribution of exchanges
  • theoretically, we need something like 100 exchanges, geographically distributed, each one doing 1% of the volume. Exchanges doing more than 5% should stop accepting new accounts, increase the trading fees for their actual customers and be boycotted by the community.
  • each exchange should be running something like the Buttercoin-whatever trading engine, what's important is that they all share some compatible APIs, and that they don't have scaling issues with php-based trading engines
  • since that the liquidity is shared among these exchanges, established exchanges should cooperate to provide additional liquidity for the single user of the single exchange. This should be made easier using the same base platform. Theoretically, the user of a little exchange with 1% of the volume should be able to do a market sell or buy for 10% of the daily volume without any problem, taking bids and asks from the remaining 99 exchanges. The exchanges would regulate themselves the fiat and btc payments during the following 24 hours, since that they trust each other. Something like a common bank account used for escrow should be possible to guarantee exchanges against each other.

As many of you, i tough about this for a while (well, not really that much, like, before sleeping for a few days) and this is the best solution that come to my mind.

It doesn't have a single point of failure, it should be scalable to the infinity and beyond, the final users can access to the whole (or big majority) of the market, maybe even doing cash deposits to the exchange whose HQ is 100km away from their homes.

The downsides are:

  • the exchanges should trust each another for fiat and/or have common bank accounts, i think that this should be possible
  • since that this way forces to a decentralization of the trading, existing exchanges won't have any incentive to migrate to the new platform, hence, this project (if feasible, i'm asking for your opinion about this), will probably never take off.

30  Bitcoin / Hardware / One oblivious effect of the price spike on the network hashrate on: April 10, 2013, 03:39:39 PM
My 7970 can mine at 10$/day using 1$ in electricity. The network difficulty has to be > 70 millions for the return to be negative.
If the price stabilizes at the 1000$/btc range, the difficulty will have to be > 250M for the power expenses to be greater than the btc mined with a GPU.

I'm sincerely scared, not from BFL, not from the helveticminer @ 28nm, but from the mass of GPUs coming online.

The return of our avalons... Is in serious danger.

What do you think?
31  Bitcoin / Hardware / Survey about the status of Avalon batch 1 deliveries on: April 01, 2013, 07:46:48 AM
I would like to have an idea of how deep this problem is to understand how much effort we have to put into convincing Avalon to give out tracking numbers for batch 2.

Please post additional info if you have not received the units or your vote will be considered invalid. Forum is too full of BFL puppets.

32  Bitcoin / Hardware / What will happens when BFL will fail to deliver during the next 50 days? on: March 21, 2013, 07:24:36 AM
I admit that I'm trolling, and that I don't have a big understanding of the iusses.
However, BFL claimed to have their chips ready almost one month ago. Again, I'm not a expert, but what I know is this:
-they have yet to show a prototype
-they have a large outflux of money due to the refunds.
-they are trying to get new orders using a lot of money on AdWords (probably in the range of 100'000$/month), this should guarantee them a positive money flow, for now.
-if the design of this chip is flawed, they will have a hard time to find the money for another 45nm run. If I'm correct these costs as much as 1 million dollar each.
-if they don't show a working prototype in, I guess, one month, their design is flawed.

If this happens, everyone with a preorder will lose his money.

Good luck, BFL fanboys!
33  Economy / Auctions / 5 x Avalon Batch 2 starting at 125BTC each on: March 20, 2013, 05:01:33 PM
Avalon announced that the unit cost of their third batch will start from 90BTC (67GH/s + Power Supply). I'm auctioning 5 units i have from the second batch starting from 150BTC each. Given the cost that Avalon applies to their third batch, i believe the opening price of this auction to be fair.
What is unfair of this auction is that i don't want to use an escrow. Selling this order, with the inability of changing the destination address, is a mess by his own. Using an escrow would make it almost impossible from my point of view.
Each unit will go for his own price, you can bid for the Avalons individually. In case a single individual bids for the all of 5 with a winning price, we can consider to use an escrow. The escrow will have in this case to release the founds right after the units arrives at the datacenter i'm shipping them to, i can route the control of my account with the datacenter to the escrow that will route that to you after releasing my founds. This is only viable way i know of using an escrow in this auction. (I cannot sell parts of my account to several people).
In case the units are purchased by more than one single individual, i will keep control of the account and give you access to the avalon so that you can point it to the pool of your choice. In this case you will have to pay me 100$/month via BTC since that i will pay the datacenter costs for you. I'm not interested into reshipping the units, i will keep control over it. I don't want to pay the datacenter to ship the avalon to you and you claiming that you received an empty box.

About my identity, you can check my username online, i use it from years. You can add me on facebook and ask my friends if they know me, you can send something at the postal address listed on "cedivad.com" to see if it's really me receiving whatever you send. I can let you VPN into my pc while i login to MTGOX where i have a verified account (they verified my residential location). All of this stuff is possible. If you have other ideas, let me know, i will evaluate them (if you win the auction and refuse to proceed otherwise). I know a few people of the italian community personally since that we do a monthly meetup in Padua, you can ask them about me if you want to.

So, summing it up.

If you bid for all of 5 the units:
-We use an escrow that will take control of my account at the datacenter that will receive the shipment and route that to you once that he verified that the avalon are in fact there.

If you bid for less than 5 units:
-We will not use an escrow and you will have to find other ways to verify my identity and trust me with this (let me say it) shitload of money.
-I will let your avalon online mining as long as you keep paying me 100$/month via BTC.
-Once that i receive your founds you are free to have your unit shipped to your home from the datacenter.

Auction ends 5 days after batch #3 orders opens. Late offers will extend the auction time by a minimal required amount, so that late bidders can bid.

Have a nice auction.
34  Economy / Speculation / What are the long term consequence of the lack of bitcoin offer on the excanges? on: March 19, 2013, 04:05:19 PM
30'000 BTC to buy to hit 100$. That's "bruscolini", something tiny.
Short term, we will hit 100$.
What will happen after?

Isn't it logic to except to see massive dumps from people that bought < 10$?
35  Economy / Speculation / Next stop: 100$ on: March 05, 2013, 08:28:41 PM
Have a nice ride everyone! (I was a bear until 35).
36  Economy / Computer hardware / [WTS] [Auction] 5 x Avalon Batch #2 on: March 01, 2013, 05:27:11 PM
I want to now what the market thinks about these Avalon, once that the auction ends i will decide whatever or not i want to sell these units. In other words this auction is not definitive and i reserve the right not to fulfill it.

Order id is #1141
The destination of the order is a datacenter in Los Angeles that will charge around 550$ monthly for the hosting (bandwidth, space, power). You can take over the contract with the datacenter in case you win the auction. We will use an escrow for the safeness of both the parties involved.
I'm interested in a bulk selling but you can also place your bid for a single unit if you wish to.

Auction details:
- I reserve the right to close it before the end of it without any previous alert for any reason
- I reserve the right not to accept any offers
- Auction will close the 6th of March at 20:00 GMT time
- Offers after this time will extend the auction for 5 minutes recursively

Again, i think that these avalon are worth a lot (i'm looking for like 100-150btc each) and this is why this auction will most probably end with a nothing of done.
37  Economy / Goods / [WTB] Avalon on: February 28, 2013, 05:25:11 PM

Just putting it there in case someone is interested.

38  Bitcoin / Hardware / Avalon will ship 290 units by tomorrow, correct? on: February 26, 2013, 02:35:15 PM
I'm sorry to open this thread but it looks like no one is worried about this.
What's really happening? Can we have an ufficial word?

Only ~5% of the units works properly?
39  Economy / Speculation / I call myself out of this game. on: February 14, 2013, 08:21:03 AM
A market where everyone thinks that he is gonna be rich in the next few years cannot work.
It made sense for me to invest in the past when I felt alone in this tough, but now, now everyone went mad.
40  Bitcoin / Hardware / A letter from Avalon on: February 12, 2013, 09:53:59 PM
a Letter from the Avalon Team

The Avalon team would like to apologize, first and foremost, for the poor performance that you may have experienced during the sales of batch two of the Avalon units.
 
This type of incident has however, been accounted for and is within our expectations. As Bitcoin payment processors and merchant solutions are still a relatively young field, much like the Avalon project itself - issues such as these will, unfortunately, show themselves in a real world situation.
 
    There's a saying: "Somebody had to be the first person to eat a crab."
 
Avalon has been bestowed with an unique opportunity to give several different Bitcoin payment processors a real world stress test: a DDoS-like shopping experience. We switch payment gateway and eCommerce solution each batch of orders to promote both decentralization and competition. In batch one, we worked closely with Paysius to hammer out its issues. This has not been any different with batch two and WalletBit. The lead developer of WalletBit, Kris, has been hard at work within the past several days, fixing the kind of issues that have only appeared from this type of real world situation.
 
This event and your brief inconvenience as Avalon customers right now will ensure that, in the future when a client ( who may not be technically-knowledgeable ) use these various Bitcoin payment processors and eCommerce solutions to accept Bitcoin for the first time, their experiences will be much more smooth and hassle-free.
 
    "May they enjoy the coming delicious crabs."
 
A third purpose of this movement is to spread recognition and funding to those services that are less well known; we at Avalon however are not playing any favorites. BitPay, for example, has been chosen as the payment gateway for batch three long before they obtained investor funding. We believe that competition breeds innovation - much like what happened in the ASIC market - and we can not wait to see what new features will result from this process. We view Bitcoin merchant solutions and payment gateways as an important part of Bitcoin adoption.
 
Batch two situation
 
We have ultimately decided not to refund the 0.05-bitcoin partial orders that have resulted from a series of errors, and allowed customers to complete their transactions out of good faith as many used third party services where refunds were not possible. We would like to take this time to warn you not to use Bitcoin addresses that you do not own, including but not limited to the following: InstaWallet, exchanges such as MtGox and others.
 
The nature of Bitcoin makes it separate from human interference and devoid of an centralized architecture. If the order database has been incomplete or compromised, then a fail-safe could be utilized to refund every transaction to their original input address. By using third party systems such as the ones listed above however, you give up the control of your own coins, and you then run the risk of your refunds returning to their input addresses. This defeats the purpose of Bitcoin. You will also not be able to prove original ownership of these coins. Our terms of sale will be updated to reflect this before batch two re-opens for the remainder 300+ units.
 
We have also collected enough money for several parts with long lead times, and these are being ordered now. Consequently, our attention will be diverted to these parts for the moment, and once they and other higher-priority matter are addressed and done, we will then reopen order for batch two. We are currently not in a rush to collect money.
 
Support situation
 
The Avalon team is comprised of a small group of capable people; however, we are also extremely limited in manpower. Every one of us handles multitude of tasks, and for this reason we will have very limited customer support. This means that you will not hear from us regarding your order until the day prior of it being loaded onto a plane heading to your country of destination. No news is good news. We apologize for this, and we do not expect this situation to change until batch three is in its production to shipping stage.
 
Our number one focus right now and always have been delivery time; everything else is considered a secondary bonus. Avalon was turned from a idea into a physical working product in less than six month because of our devotion and focus, and we have received industry attention for it. Avalon do not intent to deviate from this even as we now face a greater amount of endeavors ahead, such as working on next-generation designs and scaling production upwards. All of these are happening in parallel with our current list of to-be-completed tasks.
 
tl;dr; We do not have a date for reopening orders on batch two.
