Let's zero out the ranks, and see how the people on top again reach the legend.
Let's remove the signature campaigns and bounties. I'll be interested in seeing how the quality of post would be.
IMHO merit system did not make forum better. We should have some system to prevent shitposters from make their work. Better to have anti-merit system. When you could give negative mark to a shit or useless posts. All know that more than half of all posts here is made for signature campaign. And a lot of this posts is useless for all.
A simple scenario: Oh no, I don't agree with his point of view, DEMERIT HAMMER! / Oh no! I don't like him! DEMERIT HAMMER!

It's not easy for the community to function this way. It's a lot easier to find some of the more constructive posts than all of the shitposts. Either you get loads more whining or leave the mods with a huge mess to deal with.
3862  Bitcoin / Development & Technical Discussion / Re: Weekly Lottery for people running FULL Nodes on: February 22, 2018, 12:51:07 PM
Out of curiosity, how were they doing it? Nodes (except for Electrum nodes) don't advertise their bitcoin address, so how did they know who & where to pay?
The node owner will have to create a webpage with their address included on it. The owner (or anyone else) will have to make a request via CURL to their server for their bot to crawl the page. It's pretty common for nodes to have webpage with statistics on it. I've had a node running with the program and I just created a page with my address without any fancy stuff.
Why not introduce a Weekly Lottery, similar to the one hosted by Freebitco.in, where you have 10 different prizes and the highest price going to one lucky Full Node operator and the rest of the prizes, going to the participants. <This way, both parties are incentivized to participate>

I think it can work, but I lack the knowledge to do it, hence the suggestion here. ^smile^
Who is funding it? Why should we trust whoever is managing that incentive to not manipulate the system and have their own nodes win the lottery? Why would I want to run a full node because I can have a 1/10000 chance of winning that small prize?
3863  Other / Meta / Re: Can we have a limit to the # pages for most threads? on: February 21, 2018, 01:19:02 PM
I say that after 3 pages, see if there is any actual conversation going on and if not, lock it.
Absolutely. Most of the posts there doesn't have any actual discussion going on and is mostly just a heaven for the shitposters. I've stopped going there already. IIRC, some of those threads were either locked or moved to offtopic.
Another handy change would be to block bumping old threads (ones that haven't had a reply for six months). If there is a news update on the topic. then a new thread with a link to the old one would be more productive.
If the thread is very old, you can try reporting it as a necrobump. They would most likely be removed.
3864  Bitcoin / Development & Technical Discussion / Re: How does PoW overcome BFT on: February 21, 2018, 01:11:54 PM
So difficulty is adjusted with each block according to the network hash power. Network hash power is measured by the speed with which a block is discovered, correct?
Half correct. Bitcoin's difficulty is adjusted every 2016 blocks to take an average. Bitcoin doesn't actually care about the hashpower. They only care about the time it takes between each block and tries to get it to as close as 10 minutes as possible.
So how is a 51% attack possible? As I understand it, the new block header must be hashed using the previous block header. Why then does controlling a certain amount of the network power enable double spends?
Bitcoin is designed in such a way such that the longest chain with the valid proof of work is always correct. With 51% attack, the attacker is able to generate blocks faster than anyone else on the network. The attacker can first spend a transaction [A] and get it confirmed. Next, he will start to mine blocks starting from the point before the transaction [A] is confirmed and include a transaction [C] which spends Bitcoin to a separate place. The attacker will broadcast his own chain once he outpaces the legitimate chain. Since everyone thinks that the longest valid chain (difficulty wise) is correct, they will follow the attackers chain.

-snip-
Bitnodes.io aka. bitnodes.earn.com used to have this sort of program where it awards nodes which meets the criterion randomly, once per week IIRC. The whole program doesn't really compensate much for the overheads of running a node and it certainly does not act as huge as an incentive to run a node. The uptime for the node should be about 24/7 to have a chance, together with the others which focuses on the quality of the node.

The problem with this kind of program is that it isn't sustainable. Nodes are important but there are probably enough people running it such that a reward program isn't justified.

Does your signature campaign gives more tokens if you write more letters? Wink

you wrote exactly the same staff of your first post but with different words...
Unfortunately not. They have a fixed number of posts that they will pay for and I'm pretty sure I'll exceed that this term
. I can't really see how I could've rephrased the first post to form the second though.
i am sorry for my ironic attitude but unfortunately u didn't understand and for sure you didn't read my posts. It is clear now that you are posting for getting tokens from your signature

So, i won't explain myself anymore, i think i was clear enough to be understood
No need to apologise. Posts in meta doesn't count towards my signature campaign. I don't really care about that either, else I wouldn't be spending my time in sub forum and posts like this.

I believe that I have elaborated on the questions posed to you enough and you seem to be unwilling to address any of the questions.
3867  Bitcoin / Electrum / Re: Electrum with extended seed? on: February 20, 2018, 04:10:31 PM
First of all, stop using that version of Electrum. Search around for a Tails upgrade or just upgrade your Electrum. That version is not safe at all, please shut it down.

The extended seed option basically just increases the difficulty of anyone bruteforcing your seed. It doesn't really matter that much since the default number of mnemoric words is more than safe. Assuming that the length of the seed is 13 words, the possible number of combination is 2048^13. That is an incredibly large number and its unlikely that anyone would get to your seed in several of your lifetimes. If you'd like, the longer number of words would definitely be better with regards to this matter but I would prefer to store as little seeds as possible.

At any rate, Electrum doesn't follow any standards in their generation of seeds. Hence, any seed you generate using Electrum is incompatible with everyone else.
3868  Bitcoin / Development & Technical Discussion / Re: How many nodes blockchain.info has? on: February 20, 2018, 12:05:34 PM
I see. That is quite interesting. The main reason why I am still not fully convinced by them is because of the negative reviews that I happened to come across when I was looking for their application in the Android app store. It would seem as if a significant number of people have had negative experiences or have lost access to their bitcoins. Other reviewers, however, claim that this is mostly out of their own neglect and not knowing how to manage their bitcoins correctly and securely. To be fair to them, other reviewers also claim that it is actually quite simple and that there are even people who complain about basic things such as thinking that the network fees go to GreenAddress themselves. Another reason I have not tried it out is that it would seem as if they might not support bech32 addresses yet, even though they say they do support SegWit. I could be wrong about some of this, however, since I have not actually used them yet.
I'm sorry that I didn't reply sooner but it was buried under my recent replies and I feel that I should provide my own experience too.

I've used greenaddress previously and I feel that the concept was somewhat okay. Personally, I feel that it doesn't provide much more security than a wallet without a 2FA enabled. Now to the negative part:

Their Android app was nothing short of confusing and buggy. There was this one time where I've sent 0.044BTC to an address in a greenaddress wallet I've created on my Android app. I was certain that I have done the 2FA correctly and I didn't set any emails. IIRC, it crashed and closed after I've created the wallet. I wasn't given any warnings about it. When I tried to send the funds, the 2FA was incorrect and I was frustrated as hell. Thinking that I can get my funds back with their timelock function, I decided to wait. However, I can't send any of the files with the fact that there is no email set with the wallet. It's $500 in today's value and its terrible to see it stuck there. Their support wasn't helpful at all.

In short, stay away from Greenaddress.it. Good idea but terrible execution.

3870  Bitcoin / Bitcoin Technical Support / Re: Full Node on Raspberry Pi 3 on: February 20, 2018, 09:50:38 AM
But off topic: I have a 3 year old smartphone with a class 10 32gb micro SD card that is still going strong and not dying.

Also, drives normally die when you plug in/unplug the drive, if the rpi stays on it'll probably make the SD live a bit longer.
In most cases, the number of times that you plug in a SD card isn't the problem. I've never had a card that failed on me due to that and I remove them pretty often for various of my projects.

However, as with all non-volatile memory chips, they have a limited number of read/write cycles. SD cards and SSDs are both susceptible to this problem but I wouldn't worry too much in the case of SSDs. With SD cards, I doubt they are designed to function well under this kind of load. Bitcoin nodes are pretty resource intensive with the client fetching information ever so often. If they aren't one of the "better" ones, I wouldn't expect them to last a very long time. The SD card in your smartphone is probably fine since it didn't go through that many read/write cycles.

To the point on Raspberry Pi nodes, I feel that it is way more cost effective if you purchase a HDD to connect to it. It would be the best if you could salvage it from elsewhere. The sheer cost of a 128GB card is more than a 1TB WD HDD.
3871  Bitcoin / Bitcoin Technical Support / Re: Bitcoin transaction fee!!?? on: February 20, 2018, 09:44:12 AM
The more inputs and outputs the higher fee is required because it requires more work for miners.
No. There's no difference between a 1MB transaction and 1KB transaction to the miner. [Or in terms of block weight]
Although SegWit might play some role in this as well. Many service providers started to accept SegWit, which go activated in summer of 2017 but was not used by many and still not all wallets, merchants, services don't support it.
Seems like the Segwit adoption remains somewhat constant throughout the months. Segwit is likely not the main reason for lower fees, unless you use Segwit too.
3872  Bitcoin / Bitcoin Technical Support / Re: Bitcoin transaction fee!!?? on: February 20, 2018, 09:24:14 AM
I just wanted to know what affects the bitcoin transaction fee, what makes the fee high or low? Does the demand increase the fee too or when bitcoins price is volatile and keeps increasing or decreasing real fast, does that affect the transaction fee? Does the amount being sent decide the fee?
If not then please state the factors affecting transaction fee!
The only thing that affects the transaction fee is the amount of unconfirmed transactions and the willingness of miners to include your transaction. The fee market works in a way such that those that pays the highest fees/size will most likely be one of the top to confirm. If the number of unconfirmed transactions or transactions that pays high fees is low, then you could send your transaction with a lower fee and expect it to be confirmed in a reasonable period of time. Of course, miners can choose whichever transactions they want to include.

The number of inputs/outputs generally determine the size and hence the total fee. The amount does not matter.

This is your perspective, but the real life is out there...
Will you be kind enough to show us an example of a post of yours for which you believe is constructive? It's very subjective but the general consensus is that yours isn't, its pretty easy to tell.
Check my past posts, I am not analyzing quantum physics but i am not spamming as well
I will not get merit because i have only one account Wink Grin
Example: 50 merits for an announcement translation.  Grin Grin.
https://bitcointalk.org/index.php?topic=2796619.msg28587627#msg28587627

So this is a constructive post?
No. The merit system isn't fool-proof but it seems like it works pretty well at separating the constructive and non constructive post.
Unfortunately the status does matter.
You gave nice examples!
nullius = Copper Member
LoyceV = Legendary

So, what was the thing...? that the status does not matter... Hmm Okey, i believe you now!
Oops. But correlation =/causation. Still seems like you are reaching a bit too hard.

Copper member isn't any exclusive rank at all. Frankly, anyone can get it, if they are willing to pay. It just unlocks more features. Have you seen the content in their posts though? I would never consider a newbie or a legendary highly, unless they can at least provide content that has been well elaborated. I frankly ignore the rank when I look at posts.

I am just writing my opinion about a new rule of a forum which i'm a member and this is because I would like it to continue it's contribution to the crypto world.
Before entering this forum I only knew two words, Bitcoin & Ethereum. Today i know a lot more in depth...
The cryptos has to do with profits, further of the idea what is behind them and that the future of the world will be based on blockchains.

About your "Hmm", check my number of posts/ability to see if i am here for chasing profits (Posts: 99/Activity: 98)

Please do your homework before criticizing

Okay. Then why do you care so much about your rank? It seems like your rank is so important, to the extent that you need to type out a whole paragraph for it. Your opinion has been noted several times by the various topics with similar content. The fact that I see the signature on your signature space seems to suggest something else, together with the posts that you have with little to no substance to it.


I wasn't on my computer and thus my message was rather short.

Based on your quote:

Steadily and as the time passes, this place will become a place for hero and legendary members to discuss by themselves...
It seems like you have the impression that the rank matters so much, such that newbies and people from the lower tiers cannot hold discussions on this forum. This is completely wrong and unreasonable; it is a forum that facilitates discussion. The rank does not prohibit or censor anyone from openly discuss their thoughts or ideas. Posts or "opinions" as you may say, are welcomed. They aren't when there are literally hundreds of topics regarding this.

I know  Smiley tbh if I had merit to give, I wouldn't give it to a newbie account unless it was an above exceptional post.
Quite the contrary. I've seen most of the merits going to people who are in the lower end of the rank spectrum as opposed to legendary etc. The main reason for that perception is because most of them either repeats what is being said or has subpar post quality.

Regardless if my posts are characterized as qualitative constructive. or not,
FYI, it's not. Your rank doesn't undermine your posts. If your post has a decent substance to it, everyone will read it, no one cares about the rank.
I will never get Merits because I cannot give them back in return This is how the system works
You will never get merit because you don't post constructively period. That is how the system is supposed to work.
I am not a "famous" member.
-snip-
Neither is: nullius
LoyceV
etc. I could go on.

The point is, your status here doesn't matter. Everyone takes nullius seriously because he adds to the discussion and not because he is just a member.
In addition, my local forum will be weakening as the days pass.
The members which are having the possibility to give merits are two (LOL).
Indeed, the active members (which are also aware of the usage of the merit system) can be countable in one hand
Surprise, surprise. It is a Bitcoin forum. No one cares if you post. You only get merit when you post something that is constructive, at the very least.
As the idea of stopping the junk and spam messages will be established with great success (from the *10,000 posts daily will remain *1,000), more things will also be neutralize, as for example, the announcements of new ICO's, bounties and probably advertisements, donations and more sources that offers payments to the forum itself and thereby to forum members  

Steadily and as the time passes, this place will become a place for hero and legendary members to discuss by themselves...
As time passes, the number of farmed accounts would decrease substantially. You shouldn't be here to get paid*. If that is your main aim, this forum isn't for you. From what I've gathered from your post, it seems like the rank is the only thing that matters to you. Hmm.

* I'm never paid in Meta section nor have I really cared about getting paid or not.
3876  Bitcoin / Development & Technical Discussion / Re: Hash & Block in Bitcoin on: February 19, 2018, 07:20:01 AM
BLOCK
Block is a collection of transaction data that becomes a basic element of digital assets such as Bitcoin. When a Bitcoin transaction occurs, information about the transaction is collected and when the data reaches a predefined size, the data is merged with another Bitcoin transaction then assembled into a block. The block will be processed by the miners and verified the truth. When a transaction has entered into a block and successfully verified, that's when the Bitcoin transaction gets a confirmation.
The block contains the transactions that the miner wishes to include. They don't have to include any of the transaction that they see.

The data is never merged with another Bitcoin transaction. The miner doesn't explicitly process a block but they assemble a set of transaction and hash them to form a merkle root, which is a part of other values in a block header. The block headers is hashed repeatedly, changing the values in the block header after every hash. The miner verifies the transaction data but that happens with any other nodes on the network.
Thanks for revision my post, but my post based on trusted site and I merged it into one post, but why our opinion different? Can you show me where you get that's opinion? Or that's your private opinion? Thank you
https://en.bitcoin.it/wiki/Block_hashing_algorithm.

There's really nothing about opinions in this kind of stuff. It's just cold hard facts. I'd like to clarify that the transactions is indeed hashed together with the other transactions to form the merkle root but I feel that "merging" sounds wrong. And if its copied from elsewhere, it really isn't your opinion, but someone elses.
3877  Bitcoin / Development & Technical Discussion / Re: PoW heavy computation is a feature, not a bug --> please critique on: February 19, 2018, 07:09:09 AM
What do you think about the hash rate supply once the block reward becomes small and transaction fees dominant? I don't see an incentive for end users (tx requester) to place a higher fee if the transaction volume was to drop (e.g. when transactions are executed on the LNN leaving less volume). At this point the miner would need to feasibly supply hashing to the network, but there is no feedback for end-users to increase fees to maintain the security of the network.

or have i missed something?
Given that the block reward would take quite sometime to reach 0, the efficiency of the ASICs would likely increase quite substantially and the electrical prices would decrease. Transactions are still being transacted on chain, albeit only in the opening and closing of channels in the case of lightning network.
If the volume of Bitcoin transactions increases even more, then the mining would still likely be fairly profitable.

I agree, there is some influence that the miner has due to the process of them liquidating coins to run their operation, but the market price determination involves way more factors. What I am more concerned with is the behavior of the network once the coin supply starts to plateau and we have lightened the load of transaction volumes from the blockchain.
Bitcoin's blockchain will still likely remain as the integral part of the system for the rest of its life, as well as the miners. Lightning network helps with the micro transactions but ultimately, it would all still involve Blockchain. The transaction volume now is quite substantial, if Lightning network becomes a reality, then normal day-to-day transactions would be feasible and hence a higher overall transaction volume.
3878  Bitcoin / Development & Technical Discussion / Re: PoW heavy computation is a feature, not a bug --> please critique on: February 19, 2018, 04:32:57 AM
My understanding is that the miners have a control parameter which is "how much hashing power do I provide to the system" and that choice of control is governed by the profit of the block (profit = gross profit from block creation - [electricity + other overheads]). The gross profit from block creation is made of two functions:
- constant block reward (currently 12.5 and will halve in the future untill it becomes very small)
- transaction fees (highest fees picked from the mempool)

from this reasoning, there is currently a significant relation between electricity consumption and price of BTC, given that miners have this control parameter. But my thesis is that when the block reward diminishes, then the relation will become related to transaction fees (which should be governed by the number of transactions.)

So i guess what i want to talk about is whether what we perceive as a "limitation at present" will be the same when the block reward is no longer there (To clarify, not the limitation of transaction per second).
Miners can definitely control the amount of hash power that they want to contribute, most likely by turning on and off the miners that they own. I'm pretty sure they can try to control the clock speed that their miners run at. The problem is that miners don't really mess with them. ASICs do have a specific frequency to run at such that they have the maximum efficiency. Each miners do cost miner to keep and they should be on at all times. Else, it is a net loss and a dead weight to the miner.


Yes, my first point of reference was the news articles. But surely there is a scaling of electricity consumption with hashing power in the network? I don't want to claim that the values in the articles were accurate. But isn't there more electricity consumption? and how does it scale with PoW? And how will it scale in the future?
Yes. While more hashrate does mean that the electrical consumption will increase, it is assuming that the hardware doesn't change.
In regards to my assumption, I am not assuming that the consumption of more electricity causes a change in Bitcoin price. I am suggesting that the Bitcoin Price will effect the miners profit which will change their game theoretic choice to put more hashing power on the network. So higher BTC price results in Higher Hash Rate when the block profit function is dominated by the constant term of block reward. I hope I am making sense.
That's somewhat correct. The prices is definitely partially influenced by the miner since they do sell some Bitcoins. However, more often than not, the prices is not representative of how much hashrate there is on the network. There is no metric to compare against.

Top security practices dictate you encrypt your Bitcoin wallet with a strong password because your machine can be hacked and remotely accessed, giving the hacker the ability to download your wallet file (wallet.dat). But if it's encrypted, they have no way to open it.

The fact that you need to input your password everytime you spend btc is the security feature itself.
Passwords only protect against physical attacks against your machine. They are completely useless against RATs or any other malware for that matter. If they can access your computer, they can install a malware to capture your password. The attacker would get your password the next time you unencrypt your wallet.
