1  Alternate cryptocurrencies / Altcoin Discussion / Re: WARNING - Fake MyEtherWallet used for phishing attack in first result of Google on: October 08, 2018, 12:26:15 AM
That's a pretty terrible phishing attempt are we sure it's an actual phishing attempt or some shitty type of advertisement going on that we aren't expecting?

It's a phishing attack, the exact same copy of http://myetherwallet.com/

With many suspected redirections etc.

Be aware that fake MyEtherWallet is in first result of Google !!!

Someone used Google Ads to create a fake Announce showing in first result when someone make a search about: MyEtherWallet !!!

Spread this message to prevent from this phishing attack ... it's this kind of attack that make others give up from using cryptocurrencies.

   Thanks for the information about that. Still there are people that instead of working by their on to earn money,they love to steal from their fellow,they don't even care that other people striving just to earn for their needs.

That's why eltoo was proposed. It will be an alternative to the current penalty system. A softfork is needed. Also, it's not possible to spend all funds that are locked up in the channel - there is such a thing as reserve which is a minimum balance that channel must maintain. For example, one of my channels has 0.0049 BTC capacity; the reserve is 0.000049 BTC.

Thank you for your time reading the article ! Yes it cover many cases with offering a solutions to remedy the problems.

Eltoo solve the problem by continuously updating payment channel balances off-chain.

Soft fork is required since “SIGHASH_NOINPUT” flag for signature must be introduced to Bitcoin Protocol to make it working.

I suggest you to edit your post and add this basic video explaination about how LN works:

Paper wallet i think is the most secured solution.

External hard drive, USB,  or any same alternative can be hacked today or tomorrow ...

If you want keep your wallet on your OS, there no 100% secured OS and all can be affected by ransomware attack ... even if your OS is 100% secure (Which is impossible), programs you install on it like: Adobe products, Office, and any needed softwares for your work are not safe !!! Each time new hacker discover new bug and an army of Cryptocurrencies hunters begin to exploit it actively  ...
6  Bitcoin / Bitcoin Discussion / Re: Legal ransomware ? on: August 25, 2018, 08:49:27 PM
I think it's one stupid idea.
Basically you crypt your files and the only way to get it the decrypted is by sending a sum to an address from which those guys take a fee?
Correct me if I'm wrong but from their tiny instructions, this is all I could figure.

Besides, it's not ransomware, it's more like masochistware to me.
What if you need those files urgently and you have no BTC left?  Grin Grin

There are hundreds of ways to secure your files by encryption for free, why would you pay for this?



Of course it's not for that use !

The goal is to encrypt your files (as many as you want) and then sell it for others.

This prevent centralization in some ways and file deletion from online file hosting / or some plateform where you sell digital files.

Because of "ransom ware" this is going to be a hard sell. However there are use cases where it makes sense. I could, for example, have an online store that sells files. Rather than provide protection for the files I could sell the keys to decrypt them. So you would download say a cookbook and when you pay via bitcoin it unlocks the file for use. 

I think it's their first goal and logically the only one ...

It was my first tought when i created this thread "LEGAL RANSOMWARE"

Personally I tested it and given the waited result.

Hope this will not be used for illegal activities.

So let start with MIDDLE MAN:
-SNIP
So Bob here is the middle man, he can affect time of transaction and especially if he go offline.

The time is not a real problem since every transaction has its own timeout. It all happens nearly instantly. I have sent about 100 LN payments and the longest one took 1 minute. Bob can't steal funds because of HTLCs

LN is a network of several centralized hubs ... and you have to choose a performent and all time online to prevent delaying transaction etc ... So here a contract of trust ...

You can still open a direct channel to someone who you are going to transact with very often. Here you can see the largest nodes. Only one node has 1/4 of the total Lightning Network capacity. Keep in mind that principal is not the most important factor; the number of connections and channel balancing are much more important. The need of being online is definitely a huge disadvantage for some people, can't argue with that.

Colluding miner attacks - miners have power to decide which transactions they want to include in the block so they can refuse certain transactions selected by an attacker. This attack is very unlikely to happen due to high cost and complexity (all miners would have to cooperate).

You have to trust miners.

If ALL miners decided to cooperate with a single person then you would have to be more concerned about 51% attack. It won't happen since it would scare future investors and users. Miners would lose money long-term.

It took me some time to format this text on my phone. I am going to read what you have linked once I get home.

Instructive return, thank you.

Waiting your feedback about the link of my previous answer.

I am not the negative guy of the gang, it's great to offer solutions to improve bitcoin or blockchain technology ... but security first (Especially when people's money at stake).

You seem to be the 'uneducated' guy of the gang. At least regarding the LN.
You have a lot of misconceptions regarding the LN.



Before going furthur, stay educated and do not shoot garbage there face to someone you don't know.

So let start with MIDDLE MAN:

Quote
1. Alice opens a payment channel to Bob, and Bob opens a payment channel to Charlie.
2. Alice wants to buy something from Charlie for 1000 satoshis.
3. Charlie generates a random number and generates its SHA256 hash. Charlie gives that hash to Alice.
4. Alice uses her payment channel to Bob to pay him 1,000 satoshis, but she adds the hash Charlie gave her to the payment along with an extra condition: in order for Bob to claim the payment, he has to provide the data which was used to produce that hash.
5. Bob uses his payment channel to Charlie to pay Charlie 1,000 satoshis, and Bob adds a copy of the same condition that Alice put on the payment she gave Bob.
6. Charlie has the original data that was used to produce the hash (called a pre-image), so Charlie can use it to finalize his payment and fully receive the payment from Bob. By doing so, Charlie necessarily makes the pre-image available to Bob.
7. Bob uses the pre-image to finalize his payment from Alice

So Bob here is the middle man, he can affect time of transaction and especially if he go offline.

LN is a network of several centralized hubs ... and you have to choose a performent and all time online to prevent delaying transaction etc ... So here a contract of trust ...

I invite you to read more here for disadvantages of LN in the current state and what make it centralized:
https://medium.com/crypto-punks/lightning-network-ux-centralization-b517037b92ec

Colluding miner attacks - miners have power to decide which transactions they want to include in the block so they can refuse certain transactions selected by an attacker. This attack is very unlikely to happen due to high cost and complexity (all miners would have to cooperate).

You have to trust miners.

And please read more about "what make a technology decentralized" before posting anything else ... and also to prevent spamming this thread since the first goal is to give some knowledge about LN and not to debate it (I given my feedback like you did yourself, there many other threads about this.).
9  Bitcoin / Development & Technical Discussion / Re: Basics of the Lightning Network - explanation and wallets on: August 25, 2018, 01:35:55 AM
Thank you for this nice post !

Unfortunately this confirm that LN = centralization ! It's against Bitcoin's primary objective and personally i can't support this technology (In the current state and especially if nothing will be made to improve the idea more in decentralized way).

2 importants depreciated factors join the game: Middle man and Trust.

Of course there adventages using it like enjoying a micro transaction fees, save Blockchain transactions ... but what about security (Keeping things decentralized) ?

I am not the negative guy of the gang, it's great to offer solutions to improve bitcoin or blockchain technology ... but security first (Especially when people's money at stake).

Hi,

Anyone else learn about CZIP.ORG ?

It's described as crypto archiver and offer users to archive and crypt their files/folders, and then decrypt using Cryptocurrency Payments !

Is it innovative idea for you ? Bad or Good thing for crypto community ?

A ransomware friendly software for commercial use !
11  Bitcoin / Development & Technical Discussion / Re: how to add "generate wallet address" option in my website.. please support on: August 02, 2018, 02:03:46 AM
thank you all for help
but what if we just add 3 coin as example "etn,xvg,xrp"
and when any user make a deposit , the system automatically convert this coins to btc market price and keep this amount in every user wallet.
until make purchase order.
i think i can do it manually with chat agent, but it will be huge load.
any one can create any system like that, i will be happy to pay for his time

Coinpayments.net already do that, you can accept XRP,ETH and all other altcoins and configure to receive automatically BTC or other coin.

You can set FROM and TO coin in your request.

But if you want use your own system, you have to get the rate of each coin (ETH,XVG,XRP, BTC), using any online API (CoinMarketCap for example).

And then:
Take example of ETH:
https://coinmarketcap.com/currencies/ethereum/
https://coinmarketcap.com/currencies/bitcoin/

Quote
1 ETH = 424,34$
1 BTC = 7 685,18$

Let's say you received 3ETH and you want calculate BTC:
Quote
BTC = (3 x ETH rate USD / BTC rate USD);
BTC = (3 x 424,34 / 7685,18) BTC;
BTC ~= 0.16564609 BTC

Here is API documentation of CoinMarketCap:
https://pro.coinmarketcap.com/api/v1

12  Bitcoin / Development & Technical Discussion / Re: how to add "generate wallet address" option in my website.. please support on: July 30, 2018, 08:33:46 PM
You have 2 options:
- Using an API service
- Make your own node for each coin (This will cost you many money to invest on servers nodes)

1- For API service, you can use blockchain.com API / Blocktrail.com / or any others to accept bitcoin payments.

But apparently you want accept many altcoins aswell, so i suggest you coinpayments.net, you can accept up to 60+ Altcoins using this service.

For that, you need to be familiar with blockchain technology and learn more about it in order to start accepting payments.

The services i purposed for you, let you integrate programmatically payment solution on your website, if you want only a donation widget ... you can make a quick google search, you will get some results about that.

2- Buy and configure each server for a paticular altcoin, in this case, your money is the factor that let you know how many altcoins you will be able to accept on your website, each altcoin/cryptocurrency have their own blockchain size ... so before buying any server you have to check if it's compatible with your altcoin and if the specifications of the server meet the requirments for that altcoin.

Once done, your developers must learn about JSON RPC connection and the commands required to generate, send, receive or ... coins using a specific node server.
13  Bitcoin / Development & Technical Discussion / Re: Blocktrail/btc.com SDK Fees estimation on: July 29, 2018, 11:08:50 PM
Here is how to do it:

Code:
<?php
use Blocktrail\SDK\BlocktrailSDK;
use 
Blocktrail\SDK\Wallet;

// BEGIN - CHANGE REQUIRED INFOS
require_once __DIR__ "BLOCKTRAIL_SDK";

define("blocktrail_api"""); 
define("blocktrail_secret""");
define("blocktrail_wallet""");
define("blocktrail_password""");

$address ""// your address
$satoshi 100000// your amount in satoshi

// END - CHANGE REQUIRED INFOS

$client = new BlocktrailSDK(blocktrail_apiblocktrail_secret"BTC"false);
$wallet $client->initWallet(blocktrail_walletblocktrail_password);

$feeStrategy = \Blocktrail\SDK\Wallet::FEE_STRATEGY_LOW_PRIORITY// your fee type

$coinselect $wallet->coinSelection(
\
Blocktrail\SDK\Wallet::normalizeOutputsStruct([$address => $satoshi]),
falsefalse,
$feeStrategy
);

$fees $coinselect["fee"];

// Logs
var_dump($coinselect);
echo 
"\n Fees for this transaction will be: ".$fees;
?>

Change some informations like: BLOCKTRAIL_SDK path, blocktrail api, address where you want to send the amount, and the amount it self in ($satoshi string).

I notice the bitcoin address you are trying to send BTC to:
Code:
66f4dec6ab29cd056ce1814c6fdfee05e1524b36
are not in correct format, a Bitcoin address start with number '1' or '3',  contains 26 to 33 characters (a-z, A-Z, 0-9), excluding 'O', 'I' and 'l', to prevent visual ambiguity. And your address do not follow all this conditions ... i think you put a random MD5 string.

If it's a testnet address, please switch to testnet on Blocktrail, but i don't know if Fees estimation is supported or not for testnet, change this line:
Code:
$client = new BlocktrailSDK(blocktrail_api, blocktrail_secret, "BTC", false);
to

Code:
$client = new BlocktrailSDK(blocktrail_api, blocktrail_secret, "BTC", true);

I suggest to process payments semi-automatically ... when user submit new withdraw request, from admin panel you can process it with one button click.

I used Blocktrail API in the past, but personnaly i didn't liked it ... support is late or never answer to customers tickets/emails, and the fees for transactions are very high (I don't know if this changed from that time - Around one year ago).

Technically speaking, you're not really buying anything:

Quote
At this stage, customers will only be able to buy and sell interests in cryptocurrency and will not be able to transfer their cryptocurrency holding to other Skrill customers or use it to transact with merchants. This service will be added in the future.

So unless the ability of withdrawing your funds is added, we shouldn't be that excited.

It should be added in the futur ... it's the first step for that.

Regarding the number of users and merchants around it, it will be only benifical for Bitcoin !

In 2011 only, the company's customer base reached 25 million, including 120,000 merchant accounts, what about 2018 !

17  Bitcoin / Development & Technical Discussion / Re: How satoshi could be anonymous when he was the only full-node ? on: July 24, 2018, 02:03:27 AM
I think there was more than 1 node when he launched it, if that was the case then anyone else was able to take control of the blockchain at that time.

Second thing, is the domain name bitcoin.org, how he used to purchase it ? Purhapse any anonymous payment method at that time like Liberty Reserve or ...

But at that time, why he would manage to keep him self anonymous with this revolutionary technology ? except if he didn't want that someone will make pressure on him in the futur to stop or limit it.

Hi,

From your message it lookslike that you have problem in the way I am posting my messages !

I have a problem with clickbait topics that you make just for attention and merit....

Even with the included sources, I can see you posting spam posts like this !

You have provided nothing...
Two so-called bitcoin newspapers and a blog...
A source is this:
https://news.samsung.com/us/category/press-resources/news-releases/


For tomorrow, I would like to see Bitcoin growing more and coming with a big and good news again and again !

Bitcoin will not grow with clickbait topics

CoPay made cooperation with Samsung in order to allow him accept BITCOIN and other cryptocurrencies on official Samsung Stores.

Show me proof of those statements from Samsung...
And Copay is not a HIM.

Last thing: no one pushes you to comment or read the news I share! you can go your way or close your eyes when you see my posts, since they do not please you.

Nobody pushes you to read my comments...
But I will push the report button for this kind of threads from now on

You got official blog link of the society that made a cooperation with Samsung ! to give him autorization to accept Bitcoin on 3 countries official Samsung stores !

Do you think an official Samsung store will accept Bitcoin without autorization from the main house ?

Here is another source:
https://news.bitcoin.com/samsung-stores-in-the-baltic-states-now-accept-cryptocurrencies/

You can make some searches on google you will find many of trusted news website sharing this infos !

If you want official statement make your own searches and contact CopPay or Samsung for that, or even news websites that published this informations ! I am sharing a news only ! You got it ?

I am getting no merit for sharing this and winning nothing, on sharing news ... it's your view only and your intentions only ... it's not on BITCOIN DISCUSSION someone will look for merit ... so please ...
