A mod moved the thread here thinking a discussion about the forum doesn't belong in the board for discussions about the board.
Its now in the same subboard the other lists are. This is also your personal list, not the forum or its state you want to discuss here. The forum and the state its in might be the reason you created that list. If that was the topic you wanted to talk about a different topic and thread might be in order. I know this thread will rattle some cages across the board. It wasn't intended to do so, but it was inevitable. I've replied to any reasonable criticism appropriately thus far and will continue to do so.
I won't let the off topic section drown the thread. There are quite literally 5 times the amount of users in this board so I will seize that opportunity and increase my aggressiveness in this personal campaign. I'll continue to add about 50 or more users per day and have set this thread to a daily scripted autobump.
Good luck. |

On average a new block is created every 10 minutes. Right now there is a limit of 1 MB per block. So, if the limit isn't changed, then the growth rate is limited at: - 1 MB every 10 minutes (on average)
- 6 MB every hour (on average)
- Approximately 144 MB per day
- Just a bit over 1 GB per week
- A bit less than 4.4 GB per month
- A bit less than 52.6 GB per year
It will generally be a bit less than the limit since not every block is always filled 100%. If the block size limit is increased in the future, then the blockchain will grow faster, but making such a change will require an overwhelming majority of nodes, miners, and pools to all agree on the new rule. It is impossible to predict what limit might be agreed to, and therefore impossible to guess what the maximum growth rate would be under new rules. It is staggering to think what the impact of a 2 MB per block or even a 8 MB per block will be on the bandwidth and diskspace requirements to run a node. I agree, not all blocks will be full at all times, but what would happen, if it does. A lot of people in my country, have limitations on their internet bandwidht < Capped at 60 GB to 100 GB per month > A 8 MB per block, running at full
capacity will burn through that bandwidht in no time, so this will effectively only allow people with Uncapped internet to host a node. < Weakening decentralization > Off-chain solutions makes so much sense, when you look at these scenarios. 8*4.4 < 60 |

What? The? Fuck? They suggest TrueCrypt? True - the canary is screaming - crypt? This(!) is the official truecrypt page -> http://truecrypt.sourceforge.net/ (no SSL avalable) This(!) is the Windows 7 critical vuln found in TrueCrypt "recently" (over 1 year before the guide was written) -> https://bugs.chromium.org/p/project-zero/issues/detail?id=538&redir=1Their source for TrueCrypt has not even a sha256sum and the file is not found when I try to connect over SSL. -> https://hotbitcoins.com/software/Truecrypt7.1a.exeStep two: "create an electrum wallet on an air-gapped Windows 7 laptop", no info, nothing on how to set this up. Step six: "wipe disk" or "destroy disk" is bullshit. Either you have a proper air-gapped system in which case you dont need this or you dont.
Bonus: #1 There is no reason to suggest Windows here, Linux (tested) or MacOS (untested) would work just as well and does not need you do download an extra "file shredder" (again unofficial, bad source) #2 This is no actual guide or tutorial, its at best an idea |

Firstly, thanks for the answer. tl;dr at the bottom. Maybe you are correct and maybe you both deserve a negative rating. The problem I have right now is that I dont trust you. I dont trust icanscript either and their proof is weak, but you raised a ridiculous amount of red flags. Anyway, here is my view on this and why I left a negative rating. Bullet points version: #1 Contacting me with a signed message that proves nothing. Address in the profile of the account used to contact me, tells me the account that contacts me contacts me, nothing else. On top of that, the message didnt verify. I would expect someone that contacts an escrow to ask the escrow for verification. I started using my addy verification for future reference against anything about "verifying my identity in the future", my address states in 2 months or 1 year I'm the same one that asked for escrow and not a hacker using my account.Fair enough, I dont remember whether I could ever confirm any of your messages though. Lets just assume I could a later one to get this topic out of the way. #2 Contacting me. I have no active escrow thread, I dont activly promote this service and I was gone for 2 months. If you end up with me and I dont know you, you have either gone through a lot of other escrows and they all denied or you have a specific reason to contact me. Maybe you want to exploit my little experience in the field.
Your profile says about escrow service and your reputation plus the date since you joined this forum was enough for me to trust.
Did you not contact others before me? #3 Self moderated thread. Seriously, I dont care who you are. It makes you look bad instantly. I know the spam is bad, but the obvious troll posts had not been removed and 'local rules' are usually a better alternative.
This us used to prevent counter-marketing operations from other ICOS running at the moment, where in some cases uses several chill-accounts to attack a project, why most of them are not moderated? because most of them belong to the same group of "developers" (coming from NXT) doing an ico over an ico.
Ill accept that as something specific for the alt section, but AFAICT you have a very good mod there. #4 Rushed time frame, as SebastianJu already pointed out, the show was about to start.
Maybe this was true, but it was done for marketing reasons as several other icos were starting, not to hide something with reducing time.
Alright. (#5) The post that told people not to send to the multi sig address covered by escrows. Im still not sure who payments would have been received. Might be just miscommunication though and you actually wanted to say "not yet".
#6 The payment rate, 3% (!) of (potential) 3200 BTC. Why would you pay 3% if you can get the most trusted escrow this forum has to offer for 1%? Not only that, 3% each. That does not strike me as a sane financial plan.
The payment rate was set by escrow Dabs, not by me.
Dabs usually asks for 2% -> https://bitcointalk.org/index.php?topic=234939.0Ill ask them though. #7 The payout wording for the stages. "Stage 1, A maximum of 530 BTCs or 25% (whichever is more)". This could have potentially drained all funds.
The stages was purely set to project people from releasing all funds at once, 100% of icos outhere gain complete control of TOTAL amount collected days after crowdsale.
The wording is the opposite though. Assuming less than 530 BTC funds in total, stage 1 would have paid out all funds. #8 The stages and the amount of coins needed(?) for them.
#8.1 Stage 1 "Main net launch" and "Coin distribution". What exactly costs 530 BTC here? Is this the amount needed after stage 1 to reach stage 2?
#8.2 Android PlayStore launch is 1 month after Beta Release.
#8.3 "Stable Profit"? The idea is not new. I know people that worked on a similar project (without the special currency) in asia. It failed.
The idea is not the important but the marketing and who is leading the project, there were tens of facebook style pages before it, and for example, WAVES idea has been tested multiple times too, that multi currency payment gateway is nothing more than failed ripple project, even counter-party can make tokens, there are existing technologies using the same and not worth 30k btcs.
Hmm, I guess the gist of my question is: Why do you think you will (or would have) succeeded where others have failed. Mind you others that had finances covered. #9 No reference to past projects. This is not a small project, unless you are a well oiled machine and have experience. If you have experience, show it off to build confidence in investors.
Most current ICO developers only show reference to another past ico as their history, this should be labeled as a red flag instead of green flag, because with exception of Ethereum, all those past ICOs currency is way down in price and investors have lose part of the money they invested.
Im talking about the app, as you said yourself the currency matters little. #10 No proper signature campaign. I would expect you to be busy with the project at hand and thus hire a manager, escrow the funds for the campaign. The usual.
There was a manager managing the campaign, but he ended being a scammer in other post.
My bad, must have missed that. Added my rating accordingly. #11 Probably the biggest red flag, this all is just a concept, there is no indication that anything besides a fancy homepage was actually created.
Waves was a fancy homepage without even a proper whitepaper since they never explained how they planned to exchange fiat to crypto currencies technically and legally.
#12 Uhhh, I forgot one. Dabs and me wanted a 3rd escrow, you never contacted them and told me some bullshit about need to see an ID. Seriously, why would you require an ID from the 3rd escrow, but not from the 1st and 2nd?
Why do we needed a 3rd escrow?, Dabs did not tell me anything from this.
-snip-
I also like the idea of having a 3rd escrow to make a 2 of 4 multi sig
-snip-
I decided to remove the rating. Not because I think M28MmickT is trustworthy, but because I have no solid evidence that they scammed someone. The same is true for icanscript. The later was involved in several ICOs gone scam. Maybe hired, maybe not, I cant judge that. If anyone from DT wants to see the files regarding this, send me a PM. |

Using it over a WiFi isn't a problem, but do not use it on public computers and do not share your private key. If someone spies on the connection, they can steal sensitive info about your wallet and you don't want that to happen...
I didn't quite understand what you said about using a public wifi for transactions through Bitcoin. Do you need to share your private key when using it? I don't think you don't need to. No, you never need to share your private key. About the sensitive information about your wallet, I don't think it has sensitive information (only private keys I guess? If you decided to input it) that's the beauty of Bitcoin, you don't need to hand out real information about you.
I agree, it can be a possible privacy issue though. Someone eavesdropping on your connection can learn about the addresses you use and might even be able to connect that to a photo of yours.
Is it not possible for the hacker to see your password as you're typing it into electrum for instance and isn't there a way he could find out your wallet seed?
Not over the network, decryption is done locally. Shoulder surfing is always a risk when using a computer in public. You can mitigate that with a blanked though.  |

Hey there,
I recently launched a microwallet service.
I was wondering,
a) what's the easiest way to lower sending fees to multiple addresses?
Reduce the size in bytes as much as possible. #1 use as little inputs as possible (e.g. one) #2 use as much outputs per transaction as possible, spreading them over multiple transactions requires you to use at least one input each time. Inputs are larger in size than outputs. b) Is lighting network going to reduce tx fees? If yes, how?
Depends, do you expect a large number of transactions going back and forth between you and your users? c) Give me as many links possible please
Thanks a bunch and apologies if those questions have been answered in another 10 topics.
Links? Like any? https://anduck.net/bitcoin/fees/Regarding point b. I'm expecting a lot of withdraws. Deposits wont be more than 1% of total withdraws, since only faucet owners will be able to deposits funds on the platform. In that case I wouldnt expect much from lightning network. IMHO the best simple way for this scenario would be to reduce the number of withdrawals, e.g. by setting a relativly high minimum (0.001 or even 0.01). This also helps faucet users as they often have to pay high fees when trying to spend the coins from a faucet. On the other hand users will want to withdraw early, so maybe allow it optionally, but issue a warning that this might increase the relative fees they(!) have to pay in the future when trying to spend these coins. I wrote a bit about that here as you might[1] already know I'm doing everything you've mentioned in your post. Just need to make sure I'm not missing any other things which could help.
Thanks for the link, gonna dive into it right now
Its one of the sites that give you an estimate what a proper fee currently is (also for the past in this case). As you can see it varies and during certain times blocks are filled 50% with transactions that pay 20-30 sat/byte. It might be difficult to analyse this algorithmically, but it would give you an edge by doing withdrawals during times when the network is least used.

What sensitive info are you talking about? |
|
|

I just use the tx fee that is set by default, I figure that is enough, or it should be set higher. My txs confirmed, after about 16 hours. I am not sure if it was a coincidence, but I used a couple of those push/txs websites, after I had started the client anew on my friends computer.
But I sent 3, paid the fee, so maybe it was the server I was attached to having issues. Speed of lightning.
But they went through.
What is and what isnt a good fee constantly changes now and ranges from 50 (rare) to 100 sat/byte (more common even often too high). The concept of a default fee is no longer valid.
-snip-
Oh, just to say, I must have paid a good tx fee on all, given the blockchain stated I was a "Priority"
"The blockchain" would not state that, I assume you rely on the information given to you by blockchain.info a wallet service and blockchain explorer. It uses an outdated metric that has little to do with fee and is a bad prediction for confirmation times now. |

The only thing that anyone on that network (for example a hacker) can see is that you are using bitcoin (for example when you start your bitcoin wallet and connect) and in case there is a man in the middle he can see the transaction and that is already public knowledge as soon as you broadcast it.
with credit card however the information you type in the sites such as card number, CVV2, password,... are secret information that an attacker can use.
... if they are able to make you trust a false certificate. Which is more complex than a simple MITM. Its commonly used in many companies, but they also own the hardware so they install a pre-trusted root certificate that can sign their fake ones. |

We all know that it is not advisable to use e-banking, credit/debit cards, etc over public WiFi as the information can be misused by the hackers.
Is there any chance that the same can happen if we make bitcoin transactions over public WiFi ?
Unless you use an online wallet, no. even in case of a full MITM, the signed transaction is publicly available. The worst that can happen is that you are fed false information (sybil attack) or that your transaction is withheld from the rest of the network (DoS). I assume due to high security measures in bitcoin, it is not possible. Am I correct ?
No, its because the sensetive information do not leave your machine, it has little to do with the scenario you describe. If you are worried about the bank stuff, use a VPN you trust (works with bitcoin aswell) and/or check SSL certificates (not needed for bitcoin, unless you use an online wallet).
Broadcasting a transaction (which has to be public by it's very nature) with public wifi is perfectly fine.
Connecting any computer with private keys to any network is always a security risk.
A local network should not be trusted anyway, esp. if its unknown. If thats your default setting, you should fix that. Thats a general issue though and not related to bitcoin. |

There is another signature campaign on the services section by theforextrader. Link is here https://bitcointalk.org/index.php?topic=1703125.0 It was started a few days ago and then he announced that the current members continue the job and locked the thread and is saying that he is preparing for further set up for the campaign. Thread is self moderated (meh) and locked (huh?), the last post suggests they are not ready yet and will reopen once they have a manager. Not sure that qualifies as campaign that should be added to the list. |

I have gotten the -1 new posts error for 2 days in a row. I think a new issue has emerged because now I am getting credited some base value but I think the new posts from that day are not being added. The base value I think is the amount of my total posts from before.
The same with me Actually, it was for the first time when I saw this issue show up yesterday. The problem seems to be unrelated to the forum rejecting connections since the number of posts on the Credits tab is still shown correctly. It looks more like some part of the bot has been disabled (commented out) to avoid further confusion till the dev arrives. Those -1 posts look really strange, though. Why shouldn't it just be 0? 0 is a valid result, -1 is a typical result for "something went wrong" when coding. |

When a payment is received, blockchain.info will notify the callback URL you specify. Please note, the callback url is limited to 255 characters in length.
transaction_hash - The payment transaction hash.
address - The destination bitcoin address (part of your xPub account).
confirmations - The number of confirmations of this transaction.
value - The value of the payment received (in satoshi, so divide by 100,000,000 to get the value in BTC).
{custom parameter} - Any parameters included in the callback URL will be passed back to the callback URL in the notification. You can use this functionality to include parameters in your callback URL like invoice_id or customer_id to track which payments are associated with which of your customers.

All Bitcoin transaction that goes to blockchain can't be cancel, the transaction are all irreversible
Its not confirmed and thus not part of the blockchain yet. -snip-
Is there any way to cancel that transaction or will it cancel automaticaly after some time or did I lose all btc that I used in this transaction?
The BTC are never lost, if the transaction is not confirmed after a few days chances are high that it will be forgotten by the network adn that you can create a new one. |

Oh my, that's my problem I'm not that knowledgeable about the specifics, I don't know if what should I copy and paste or whatever. Anyway in case of electrum, I'll try to download it and see how it goes. Thanks Shorena
Am I doing this correctly? Here is the code below with mycelium address This is zero1ten from bitcointalk.org and today is 2016/12/06
1tyg1zSVXL22vsXoV8yfuWi97XipC734E
It has the address and the message, but its missing the actual signature part. Sorry I'm such a noob, here below I copied a format -----BEGIN BITCOIN SIGNED MESSAGE-----
This is zero1ten from bitcointalk.org
-----BEGIN BITCOIN SIGNATURE-----
Version: Bitcoin-qt (1.0)
Address: 1tyg1zSVXL22vsXoV8yfuWi97XipC734E

-----END BITCOIN SIGNATURE-----
How about this one? Edit: I think there is no signed message option in mycelium ios wallet app unlike in the android version Edit2: or is it the public key portion? Is that the one I supposed to put? Sorry again for bothering Edit3: I put the public key I dont know if you can sign with the iOS version, I cant test it. The xpub is not the signature, its like all your addresses in one code. If you care about privacy you shouldnt post that publicly, but since this is a test it doesnt matter much. The signature is specific for the message you want to sign and address you want to sign with, you need to select "Sign Message" or something similar. It should at the very least ask you for a message. |

Hello. I have big problem. My wallet (Electrum) let me to spent amount that wasn't fully confirmed (only 1 confirmation). So this is what happend and how : I got bitcoins in my wallet, it get 1 confirmation, I sent it to other address and it stuck with 0 confirmation and confirmation warning : "This transaction spends an input which is unconfirmed" . I checked first transaction(transaction in which I got btc to my wallet) and guess what it also bocome unconfirmed. That transaction was confirmed (in details in electrom wallet there is information that there is 73 confirmation but when you look on blockchain it is unconfirmed with 0 confirmations) so how it lost confirmations and what action I can do now to unstuck that transactions. So here are transaction : 1. https://blockchain.info/tx/0748579ea3df24e2312d1ea53be28f7eae0c92f09c271e0721d5b716f134d142 (this is first transaction in which bitcoins was send to my wallet - first it was confirmed, but when I sent that btc to other address it lost confirmations and become unconfirmed) I tried to rebroadcast this and my node replied: transaction already in block chain (code -27)
As you can see here -> https://www.blocktrail.com/BTC/tx/0748579ea3df24e2312d1ea53be28f7eae0c92f09c271e0721d5b716f134d142it has 75 confirmations. 2. https://blockchain.info/tx/55d7bedaf4e9c14f4cb58762d7334bcbd92687c9cc8a265e542892a623d8923d (this is second transaction where I sent btc to another address, here is part that I send amount of btc from first tranasaction that wasn't fully confirmed, if you click show scripts and coinbase you will see that amount that got stuck is same amount from first transaction) This is not stuck with small fee (fee is biger than normal) but becouse spending amount that wasn't confirmed so double spending with increased fee is not solution here. Can someone help me and give me advice how to unstuck that bitcoins? The fee is fine, it should confirm soon. I rebroadcasted it in order to make sure its not forgotten. You can do see yourself if you take the raw transaction, e.g. from here[1] and use one of the pages listed here[2] [1] https://blockchain.info/tx/55d7bedaf4e9c14f4cb58762d7334bcbd92687c9cc8a265e542892a623d8923d?format=hex[2] https://en.bitcoin.it/wiki/Transaction_broadcastingIt is strange becouse on coinbase it write first transaction is unconfirmed and on other places (including my wallet) it write it has 75 confirmation. In second transaction there is warning that it spent unconfirmed amount and when you click show scripts and coinbase there is (U) next to that amount (12ujCstpjNkwansEaPsyJv2WiPrCAUczAa (U) (0.13829395 BTC - Output) ) . I hope it will be solved soon but I waited for 14+ hours and this bothers me. Coinbase runs full nodes[1] to get their data same as blockchain.info and blocktrail.com. If their data suggests a TX with 75 confirmations is unconfirmed, it means their node is at least 75 blocks behind. It might be something that will be solved on its own, or maybe they currently have problems with their node. [1] Its just a guess, they could also rely on others running a full node as a service, via an API. The details shouldnt matter here though |

I think I messed up big but maybe someone can tell me if I can recover from this. I made a wallet a long time ago on Electrum to import my key and send BTC to my coinbase account. I did not write the paraphrase down and I wrote down the wrong password! I went back a few months later and I imported another private key in Electrum so that I could send to my coinbase account. But it is asking me for a password and it keeps saying it is incorrect. I have tried everything I could think of but no luck. Any suggestions?
Where did you generate the key you imported? Do you still have a copy? If, yes the wallet does not matter and you can import the keys into a new one. If you no longer have access to the private keys you imported, its true you cant restore from the seed. Electrum is pretty easy to brute force though, because its not well protected against these kind of attacks. A common tool for this would be btcrecover[1]. Testing a few billion passwords should be no problem, the question is whether or not you remember enough about your password.

thinking again , remember your password .. you can recover with phone number, you cant recover an electrum wallet with a phone number. |
