4681  Bitcoin / Bitcoin Technical Support / Re: 0-fee transaction on: March 14, 2017, 12:58:02 AM
I deliberately created the no-fee transaction http://blockr.io/tx/info/74ccfd796cf2cb404a2245f699fd0e5cdf2a3a6b8a7b9cf1169ff2f87c124557 from my Armory wallet in order to see how long it would take to be confirmed into the blockchain.  https://bitcoinfees.21.co/ indicates something like 23-Inf blocks but the number is some sort of best case scenario.  I think maybe some/most/all miners aren't bothering to include any no-fee transactions in the reserved section of blocks anymore.  I asked the 21.co guys and they said they might try to improve that portion of their fee reporting page.  I'm going to leave the transaction alone a while longer to see if it goes through as long as blockr.io still sees it and doesn't drop it.

I don't think so but will my Armory wallet eventually timeout or something automatically or will I have to take deliberate steps to rectify the situation?
Hey, what do you know, it went through.  So, some no-fee transactions are still getting through eventually.  Mine only took 11 days.
Did you pay bitfury to get your transaction confirmed? I am surprised that you were even able to get that to propagate, let alone confirm with the current mempool environment.

4684  Bitcoin / Electrum / Re: Electrum 2.8 is released on: March 13, 2017, 08:01:21 AM
If a user has a pre-version 2.8 wallet that they wish to remain encrypted, that currently contains BTC and/or transactions are anticipated to be received by addresses within the wallet, how upgrading to 2.8 affect their wallet? Will they need to keep this wallet unencrypted in order to spend BTC in that old wallet?
4685  Bitcoin / Development & Technical Discussion / Re: A thought occured today, are "bulk" transactions cheaper? on: March 13, 2017, 05:49:03 AM
This is probably not true.

It is unlikely that a for-profit business is going to spend the exact same amounts of money that they receive (otherwise you probably wouldn't be earning a profit), and as a result of this, it is likely that you will need to send a BTC to a change address for each transaction that you send. Sending to 10 change addresses in 10 transactions is going to be more expensive than sending to 1 change address in one transaction. If you split up your transactions so that you have one transaction for each payment, then you are going to have to eventually spend the money that you sent to these change addresses, which would cause you to have an additional input for each change address.

With limitations, for each transaction you can eliminate to combine multiple payments into one transaction, you will save the cost associated with one input and one output.

Part of it is similar to a web wallet. Each user has their own keys and addresses rather than just a number in a database that shows how much they have. Instead of sending each transaction to the network as soon as it is made, I will add them together into one larger one saving on overhead.

The exact working out of it all is yet to be figured out. At the moment I am writing software for card terminals Smiley
Well that will change things a little bit. Probably most importantly, you need to understand that you cannot simply "add transactions together," all of the inputs in a transaction need to sign the entire transaction -- this means that if you have a transaction in which 7 users are sending funds, but only 5 of those users sign the transaction (assuming 1 user = 1 input), then you will not be able to send any of the transaction until the remaining two users sign the transaction, or alternatively you create a new transaction spending funds from the 5 cooperating users, that each of them sign. This will result in you having a tradeoff in that it is likely that many of your transactions will fail because users refuse to sign a particular transaction for one reason or another, and depending on how many users you have/how frequently you are creating transactions, this may lead to long delays in being able to even broadcast a transaction.

Additionally, if each user has their own address and own private keys, then I would presume that if a user does not spend an entire input, that they will also have their own change address, which would mitigate the savings that I described above.

Under my understanding of your setup, you would save about 40 bytes per transaction that you can eliminate, and you would have the tradeoff that there might be delays in broadcasting transactions.

One other thing to keep in mind is that having large transactions might result in you having to pay higher tx fees rates (on a per byte basis). For example, if your transaction is only 0.24 kB, then your transaction might be the cheapest transaction confirmed in a block if you are paying 0.0000012 BTC per byte because there are no 0.24 kB transactions that pay that high of a rate. However if your transaction is 150 kB, you might need to pay something closer to 0.0000018 BTC per byte because you will need to outbid many more transactions competing for that greater block space.

I have no idea about the mods but this point isn't right.

Quote
If miners had to 'find something else profitable to mine', they'd just start mining
double spends depositing BTC to the exchanges that are trying to remove them from the business.

If miners do this then the exchanges can start waiting for many more confirmations, which will work as long as the attacking coalition is less than 50%
Since about two weeks after signaling for SegWit started, support has held steady at about 25% plus or minus small variance.

In other words, there are currently miners who are totaling ~75% of the network hasharate who would be against the UASF.

Also variance can let someone with around 35% or so of the network double spend a transaction with 6 confirmations, only this is horribly unprofitable because it will not work most of the time, and when it does not work, the miners would be giving up their block rewards.



I think the answer to piotr_n's question is:
"Someone who very much wants SegWit to activate"

Are you offering any kind of collateral for this "investment" or is it based entirely on trust? If on trust, then why should anyone trust you?

It is based on trust and a valid registered company at the Dutch chamber of Commerce (and a contract).

I've done trades in BTC for a total near 300k in the past on this forum. Some shows in my trust rating, and hopefully their are also people here on the fprum that can bouch for my previous webshop (usbminers.nl ) that was one of the biggest webshops in Holland for the mining community. Their are forum members here that have ordered for over 50k at my store in the past.
Your trust shows that you have only been entrusted with a few hundred to a few thousand dollars worth of others' money at a time, and for short periods. Your trust also shows something closer to around $10k in trades as opposed to $300k, although some of your trades may not have involved the leaving of trust rating at their conclusion. Could you maybe have some of your trading partners post that they have traded with you, the value of the trade at the time of the trade, and if they trusted you as part of the trade?

Another concern is that most of your trades involve Casascius coins, which is Suspect is not the case for your business proposal (I don't know what you are doing, so I might be wrong on this). How much experience do you have in the line of business you are proposing entering into? Even if you are not going to outright steal the money, this does not mean your project will automatically be successful.

4689  Economy / Collectibles / Re: Alitin Mint Adam Smith Coins compromised! on: March 12, 2017, 08:07:00 PM
Only if he's dumb enough to cash out.
Blockchain analysis shows the coins were immediately sent through a mixer so the thief could have pretty easily cashed out by now.

Are mixers really useful for large volumes? Have not checked them in quite a while, but when someone with >100btc trying to mix it becomes pretty obvious which output coins are his. So while it might not be a conclusive evidence, once he cashes out and it turns that he used to work at alitin at the time, dots connect and case opens.
That probably depends on how you define "large volumes". I don't think the few hundred BTC that is the upper bound of what the thief took would be easy to trace, especially if multiple mixers are used.

You would probably need to move four digits worth of coins in a short period in order to potentially have your coins traced with blockchain analysis.

4697  Other / Meta / Re: Ethical issue about ignoring hacked account on: March 11, 2017, 08:48:16 PM
There is no authoritative way to say that an account is "hacked".

If a new user buys your account from you with the intention of participating in a signature campaign, but is not experienced enough, nor has done sufficient research to know to ask for a signed message, then your account is not hacked. The presence of a signed message will not prove that an account was hacked.

If someone infects your computer with malware, and is able to steal both your private keys and your passwords, then the hacker will be able to produce a signed message claiming the account was sold, yet it would in fact be hacked.

There are many other situations in which the issue is muddy when dealing with potentially hacked accounts.

For the most part, the forum does not get involved in these kinds of disputes. It is also fairly rare that accounts get hacked because of a security breach on the part of the forum, although this is somewhat more common now because of the 2015 hack -- if your account is getting hacked two years after the fact, then this is really your fault because you very much should have been aware that you should have changed your password. Most "true" account hacks are the result of the end user making some kind of mistake.
4698  Economy / Lending / Re: Need 10 BTC - 10% - with escrow on: March 11, 2017, 04:18:39 PM
This is a very risky proposition because of the risk that poloinex will recover your account back to you. I would think that it would not take much more than a signed message from a withdrawal and/or deposit address for you to have full control over the account.

How? In minutes? they will recovery in minutes?  And why? I'm just want to reduce my losses..
I am not sure why you are asking how quickly they would recover your account. This does not matter. It would probably not be minutes but would probably be quick enough so that the escrow would not be able to secure your account.

4699  Other / Meta / Re: Account farming. Allowed? on: March 11, 2017, 07:37:43 AM
I'm a bit confused about the "24th nov" date. I thought it was significant on older dormant accounts reactivating, not ones created on that day.
I found hundreds of "old" accounts all being reactivated on 24 nov 2016, and other more recent dates.
(40% of ALL old accounts i randomly looked at had been "reactivated".

This is most likely accounts getting hacked. The members list was leaked in the hack that occurred in 2015 that included the hash of accounts' passwords -- passwords need to be cracked individually so it is probably that someone was able to crack these accounts' passwords, likely because they had weak passwords.
4700  Other / Meta / Re: I have an idea, lets talk and bring something awesome on: March 11, 2017, 07:32:31 AM
The forum very explicitly does not endorse any trades, nor any traders, so anyone considering to conduct business here needs to make their own decision if they want to trust a potential trading partner or not.

Even if a person's RL identity could be authoritatively confirmed (it realistically cannot), this will not prevent them from stealing other peoples' money.

The question of if someone should be trusted or not is not a binary question, it might be a good idea to trust someone with $100 while it would not be a good idea to trust that person with $1,000. Similarly it might be safe to trust someone with certain types of trades, but not others.
