41  Bitcoin / Development & Technical Discussion / Re: Transactions per seconds (help to calculate) on: May 06, 2018, 04:26:49 PM
The simple way to calculate the number of Transactions Per Second (TPS) Bitcoin can handle is to divide the block size limit by the expected average size of transactions, divided by the average number of seconds between blocks.

I believe that the average transaction size has increased, so that means that Bitcoin in it's current state can not have TPS of 7. The average transaction size of the last 1000 blocks is 534 bytes. With 10 minutes you would get: 1,000,000 / 534 / 600 = 3.1. If the block time for Bitcoin is decreased to ten you would get 3.1 * 10 = 31 TPS.

For Litecoin I can not really find the average transaction size, so if you take the same value you of 535 bytes per transaction you also get 31 TPS.

If you really want to know it then you will have to make a script which grabs the size and amount of transactions in the last 1000 blocks. Next you will have to divide the block size by the amount of transaction for each block and it up, then finally divide this value by 1000.

The summary of it all is that, we just need to continue to be more secure. I have read suggestions about how to go about being secure but it seems its not as simple for someone who is just an average user. A whole lot of people don't even know what DNS stands for and its importance in all of this or what the validity of the certificate stands for what is known is to launch a browser and sail with it to site you want to visit.

The simple answer and best recommendation is have an hardware wallet to store the coins. As the Internet continues to be less secure, the best is to operate outside the internet and only come online to use the wallet when its extremely important to do that.
This thread suggests that the ISP DNS server is the most secure. Most devices are pre-configured to use DHCP and that will automatically choose that server, so you don't necessary have to understand DNS for basic security.

Hardware wallets can be considered hot-wallets, as they are physically connected to an online device. But I get your point.

I always use VPN to transact. I do not know if this is risky or not for me. And so far I am grateful my coins are always safe. Whether through MEW or Exchangers, I'm always wary of using both because we know that Hackers can use DNS from MEW or Exchangers to get Private keys and Passwords. They are smart. However, risk is the part we have to deal with.
I'm using a VPN too, is this safe enough?? (I'm not a tech savvy so i don't have any idea about this) Well, this makes me scared but thanks God my tokens are still safe out there, to be honest I'm just worried about MEW wallet, not exchange since I have enabled 2fa factor though it's not completely safe and bad way storing your crypto out there.

I would not use a VPN for logging into web-wallets, unless Bitcoin (or related tech) is forbidden in your country. You have to consider that all requests go through the VPN server, that is especially dangerous when the connection is not well encrypted.

This has been talked about on this forum. Roger Ver has been (supposedly) misleading newbies, making them believe that bitcoin cash is the real bitcoin:

Bitcoin Cash is the real Bitcoin.  Allah is the real God; Jesus is a phony.  To adherents on both sides, the other side is just fucking outrageous and needs to die.  
Thank you for your meaningful contribution again. You still do not see that Ver only wants your money, don't you? He definitely helped Bitcoin to become a 'thing' but now he seems to want money for it in exchange, even if it's harming Bitcoin.
45  Other / Beginners & Help / Re: "out of sync" on: May 06, 2018, 11:08:13 AM
I have already uninstalled the wallet 3 times and I do have version 1.0.3.0-154e367 (64bit)
this is clearly NOT Bitcoin Core wallet (current ver. 0.16.0) and certainly not Electrum with version 3.1.3
searching by version given, I can't seem to find any wallet with that version number
I think that he is running Bitcoin Unlimited, as the latest version is 1.3.0.1 and he is talking about a full node wallet.
But the same advice applies for this wallet, wait till it is fully synced or change to a different one.

I feel that these kind of lawsuits will never get off the ground, or are doomed for failure if they ever get started. When nobody owns the Bitcoin trademark and there are thousands of forks getting generated which use the Bitcoin brand, it would be tough to point fingers at Roger Ver and Bitcoin Cash.
I feel feel the same way, it could potentially make the situation even worse if the case gets more media attention. Negative attention is still attention, we have seen this many times before.

so what do you propose? should we sit around silently while scammers have fun and fill their pockets by ripping people off?
he is correct that bitcoin is not a trademark and is not owned by anyone but also that means we are all responsible for bitcoin if we are using it. every single one of us. and when we see someone abusing the "name" and the power they have (money and control of key domain names) we need to do something about it.
You are right, we should definitely give it a try. Maybe I was a little pessimistic, but I still think that it will be hard case considering the trademark not being owned and the opposite side having a lot of money. They could easily hire some professional people to the defend themselves, while Bitcoin is depends upon volunteers.

the tittle says it all folks, the transfer fees are too significant for me personally so I always look for the best option that will keep my loss* minimal, any thoughts ppl?
you are not just helping me but a lot of people Smiley)


* the best I can do at the moment is  2-3% loss between bids/asks and the exchange fees.
Litecoin is quite identical to Bitcoin but has lower transaction cost and faster confirmations. It's also pretty easy to get your hands on, compared to other altcoins.

basically LTC is what I use now.
It has less traffic on it's network compared to Bitcoin, so it should do the job. Besides the block times being quartered, which should make it four times quicker.

Warn users for the consequences of these campaigns and the staff should actually remove these type of campaigns from the forums. Also we should not give to much attention about this topic, it could make people curious to these kind of campaigns and potentially join because of the urge to make easy money.

52  Bitcoin / Development & Technical Discussion / Re: Bitmain claims another crack against PoW: This time Equihash on: May 05, 2018, 11:31:49 AM

Have you heard about dumping? Bitmain simply dumps and continues dumping for a long period, believe me they can go for years, selling their products half the price of hypothetical competitors.

Good example is it's new Antminer V9, which are just refurbished S7 miners (under clocked).
53  Other / Beginners & Help / Re: Graphic Card for Bitcoin Mining? on: May 05, 2018, 11:18:05 AM
It is not efficient to mine Bitcoin using a GPU, as ASIC chips are way more powerful at solving SHA-256d and therefore outperform GPUs. So, the answer is none, you would rather use a GPU for coins using different mining algorithm, for example ethash.


Best card for mining bitcoin is Bitmains GPU named ASIC Antminer S9
The Antminer S9 is not a Graphics processing unit but rather an ASIC chip which stands for application specific integrated circuit.
54  Other / Beginners & Help / Re: "out of sync" on: May 05, 2018, 10:53:11 AM
Configure Bitcoin Core in pruning mode or use a SPV wallet instead, for example Electrum. In case you want to run a full node, then you will have to wait till it's properly synced. It could take some time as the current blockchain size is over 140 Gb.
55  Bitcoin / Development & Technical Discussion / Re: How to securely generate private key with javascript? on: May 05, 2018, 10:15:48 AM
The most secure way is to download the bitaddress source from Github and move it to a flashdrive, like NeuroticFish describes. Then you follow this guide:

To generate your own entropy you’ll need five 6-sided dice, preferably high quality casino dice for true random numbers.

Roll the five dice and arrange in any order to create one 5-digit number. Use this dice number list [http://world.std.com/~reinhold/dicewarewordlist.pdf] to obtain a word for the roll. If, for example, you rolled 11121, your word would be aaron. Repeat this 24 times, since you’ll need 24 words for a secure seed.

Write down each word on one piece of paper like this. This will create the seed that will be used as the random entropy for your paper wallets.

Create multiple copies of the word list and store in multiple locations. Laminate each copy and store in a fireproof safe if possible.

Remember to write it down! Then afterwards click on the "brain wallet" button, like shown below:



Fill down your 24 word list two times and click view, now you have successfully generated a bitcoin address.
Write down your paper wallet (printing adds an extra attack vector) and make sure to check for errors.
Finally destroy your flashdrive and never use it again.

Ik ben eigenlijk wel benieuwd wat onze Bitcoin grondlegger van het huidige systeem denkt. Na zijn onverwachtse vertrek zijn er zo veel dingen verandert hier, om maar een voorbeeld te noemen, het activity systeem. Wat op zichzelf niet perse tegenstrijdig is met zijn idealen, toch is alles daarom heen totaal niet wat hij in gedachte had lijkt me. De hele rangorde hier heeft veel weg van de huidige maatschappij waarin er een elite is die de boel bepaalt, dat lijkt zich met dit systeem in zekere maten ook hier gecreëerd te hebben en dat was nou precies waar Satoshi verandering in wilde brengen. Met de toevoeging van dit merit systeem is het eigenlijk alleen maar erger geworden, het is nu meer een weerspiegeling van de huidige maatschappij waarin er een groep mensen is die jouw mag beoordelen op je doen en laten.

De beheersing van de Engelse taal onder Nederlanders lijkt inderdaad in dit geval tegen te werken. Ook omdat het onwaarschijnlijker is om merits te krijgen voor je bijdrage in grote threads ten opzichte van kleine threads. De nationale forums lijken toch net wat minder onder bevolkt te zijn dan de algemene forums die soms wel honderden pagina's lang zijn.

Je slaat hier nagels met koppen. Ik ben zelf een overtuigde libertariër - ik ontdekte BTC via ideologische sites - en sta soms zelf te twijfelen over mijn overtuigingen: hoe verwachten we onze economie te "ontregelen" als we het nog niet eens kunnen op een forum...

En in praktijk gaat het nog dieper: hier vallen bounties te rapen, en je betaalt daar geen enkel toegangsgeld voor. En daar begint het al: voor niks gaat de zon op. Want dit forum moet ook draaiende blijven, en dat kost ook geld. Misschien moet het VIP-geld van 2 BTC ook maar eens herbekeken worden, want die kosten nu heel veel EUR, maar anderzijds mogen we als BTC-supporters geen rekening houden met de fiat-waarde..... Zucht enzovoort enzovoort..... Smiley

Ik weet het ook niet zo meteen, maar ik vind wel dat de toegang tot dit forum niet noodzakelijk vrijblijvend moet zijn en dat betekent voor mij ook niet dat het dan automatisch elitaristisch wordt.

Dankjewel, eigenlijk is het dus helemaal niet zo gek dat Satoshi zijn eigen project heeft verlaten. Ik denk dat hij of zij de huidige problemen al voorzag, alleen al de discussie over de blokvergroting heeft veroorzaakt dat de community in twee delen is opgesplitst. Wat je zegt klopt, voor niks gaat de zon op dus donateurs zijn/waren zeker nodig, deze mensen mag je hier ook best mee in het zonnetje zetten door hun naam bijvoorbeeld te tonen op een speciale pagina. Maar het onderscheiden van mensen op basis van het aantal posts en waardering lijkt me redelijk belachelijk voor een forum betreffende Bitcoin. Donaties schijnen ook niet meer nodig te zijn volgens Theymos, het forum zou genoeg Bitcoins hebben ontvangen om nog lang te kunnen draaien. Begrijp me niet verkeerd, het forum is een mooie plek voor discussie maar ik denk niet dat het de oorspronkelijke idealen nog kan ondersteunen. Overigens waardeer ik wel dat je hier zonder censuur je mening mag geven, zelfs als het kritiek is.

Hey mate thanks for the alarm.

I tried to search it as you said and this what came out.

Quote
- I think the owner of that cken you've searched and this one is the same.

These scammers / hackers can't really do something with their lives and never stops to get a victim through google search.

-snip-

Why google allows this?
I remember users reporting the exact same attack for bitaddress, multiple thousand dollars worth of Bitcoin were stolen in this attack. The people that operate these websites seem to have no conscience. It also seems that Google does not check the content of their adwords publishers manually, which is really disgusting. I guess the only thing we can do is reporting these phishing websites manually.
These phishers / scammers doesn't have conscience and we can't expect any goodness from them.

That's the money that they are feeding to themselves and possibly to their children too. Reporting will help and for sure google will handle them seriously unlike before that these phishing attempts has been advertised by them.


I really hope they do, as these phishing attempts damage the reputation of Bitcoin.

Hallo allemaal
Zijn er mensen hier die denken dat BTC Zal weer $20000 bereiken of zelfs meer? Zo ja, op wat baseer je dat?

Alvast bedankt
Als het lightning netwerk waar maakt wat het belooft dan vermoed ik dat $20.000 geen onwaarschijnlijke prijs is. Dit zou betekenen dat Bitcoin vele malen meer transacties per seconde kan verwerken dan bijvoorbeeld VISA. Ook zou dit de schaalproblemen die Bitcoin heeft permanent moeten oplossen en dus zullen hoge transactie kosten en verwerkingstijden in de blockchain verleden tijd zijn. Dit huidige probleem lijkt de prijs van Bitcoin nogal tegen te werken en dus vermoed ik dat de prijs zal stijgen wanneer dit zich oplost zonder ernstige bijwerkingen (bijv. grotere blokken).

@Aura: BTC werd bedacht als libertarisch concept en dan vind ik het ook vreemd dat er extra regeltjes komen op het forum. Druist volgens mij volledig in tegen de oorspronkelijke ideeën van Satoshi. De verleiding om aan regeltjes toe te geven is oh zo groot...

Wat niet wegneemt dat ik ook me ook dooderger aan al die spam. Of aan posts van mensen die de topic niet lezen, zoals @Anycoin hierboven. Tongue

Tot slot, zei ik het al: het feit dat wij allen perfect Engelstalig zijn, in tegenstelling tot de Russen, Fransen enz. die ik in de OP heb vermeld, speelt hier zeker in ons nadeel.

Cheers guys, ik zal jullie sMerits eveneens nuttig gebruiken!
