How Bitcoin Can Be Hacked. One Way to Do it. (Not clickbait)

I refer to this post at https://www.reddit.com/ethfinance/comments/e52zyc/vertcoin_network_sabotaged_by_another_51_attack/.
There is something we can learn from this event. Vertcoin is a fork of Bitcoin protocol. So by right, technically, if Vertcoin can be attacked successfully, so can Bitcoin. Although maybe nobody have yet to figure out the way, sometime in the past I have a rough idea on how this can be made possible. While Vertcoin was successfully attacked by way of having more than 50% of its hashing power, the same requirement may not be necessary with Bitcoin, as we understand the longest chain takes precedence to become the main chain. So the question is, how can an attacker successfully reorg the Bitcoin chain cheaply, without having majority hashing power, and still be able to create the longest chain?
Theoretically, I can think of one approach. Here's how I think it is possible.
  1. An attacker (with full node of Bitcoin blockchain for all its historical data) process his mining offline, while continue to maintain the full node online, for most current data feed purpose.
  2. With this offline chain, the attacker possesses 100% of all the hashing power with no competition. Of course, this offline chain will still have all the actual historical record of all Bitcoin transactions details.
  3. With this 100% hashing power, the attacker identifies which block to reorg (no matter how old this block is) and re-mine all the blocks starting from there, offline, for their hashes.
  4. As he is the sole miner in his own offline chain, he will be able to overcome the mining difficulty and obtain all the hashes of all the blocks that will be reorged, up to the latest block.
  5. The attacker proceed to do multiple of his own transactions (offline, of course) beyond the most current transactions that are being done on the online chain, to obtain all the necessary hashes of his transactions.
  6. With all the hashes he found from reorg-ing his offline chain, he returns to the online chain that everyone is in, introduces all the hashes from all the way back to the block he intends to reorg up to the latest, plus further transactions of his own (already done offline, with all the needed hashes), and create the longest chain.
The idea is to take the mining difficulty offline (to make it manageable by eliminating miner competition by being the sole miner), figure out all the hashes of all the reorged blocks, offline, return to online mining, reorg the online chain by introducing all the new hashes found from offline mining to the online chain, and maintain the reorged chain as the longest chain to supplant the actual online Bitcoin blockchain.
Theoretically, with sufficient resource and expertise to do it optimally, the effort to reorg should be cheap, fast, and easy to implement, without the need to possess 51% mining power.
One constraint is that the attacker needs to mine his offline chain concurrently and in parallel with the online chain because he needs to keep track of the latest transaction details committed on the online block, to reorg them offline for the reorged hashes, that he will introduce online.
To be able to mine (or reorg) his offline chain concurrently and in parallel with the online chain, he will need a smart algorithm for that concurrency and parallelism. Such need for concurrency and parallelism is important NOT to reorg the chain, but to successfully supplant the actual online chain with the attacker's own newest transaction blocks for the longest chain.
Why a 51% hashing power is not necessary?
As mining is all about brute force + a lot of good luck, a miner does not necessarily need to have 51% hashing power to successfully mine a block, otherwise all small miners would die out already by now.
All he need is just damn good luck at the right time for that split second advantage (or maybe just 10 minutes minimum) to supplant the actual chain with his reorged chain successfully.
No need to have 51% mining power. And no need to have multi million budget to do it.
Disclaimer: My approach is just a theory.

I need private advice on how to open an exchange account for bitcoin and maintain my anonymity (the point is to perform a transaction, but more details if you PM)

Thank you in advance. It’s really important, guys. I can’t afford a mistake.

I am not a big user of bitcoin, I send 31$ in BTC and the transaction is still pending for 2h... is this normal? I don’t understand anything to the transaction details. It’s really hard to understand how work bitcoin exactly

Cryptocurrency: Bitcoin For Beginner

Welcome all Peeps!
Today I am presenting you an abstract but brief intro about Bitcoin. As a Bitcoin enthusiast, many of you like me want to learn about Bitcoin.
So let’s start the journey of Bitcoin.
Here I am presenting you overall abstract quality and accurate results on Bitcoin with simplicity.
First Bitcoin is the fastest growing digital currency in the market right now.

Let's Know a bit History.

Bitcoin was first introduced in 2009 by pseudonymous programmer under name Satoshi Nakamoto and the real identity is still unknown. Basically it was defined as peer to peer electronic payment system based on complex mathematical algorithms.
Bitcoin is the digital currency which is based on an open-source protocol encryption network which is totally decentralized.Means people will only have authority over money rather than any particular Center or organization.
Recently Bitcoin become the center of attraction since 2017, as the very famous ransomware attack hits across the globe and many organizations became the victims of this attack.
As the organizations becoming the victims, their data getting compromised and the attackers demanding money as a result of data recovery in the form of digital currency name Bitcoin.
From here now the journey of Bitcoin and all digital currencies booming like a sun ray.
Nowadays, Bitcoins are used for paying as well as for trading purpose similar to other known fiat currencies.
Literally
Today's Figures: (its very flexible like share market)
1 Bitcoin = 443,015.88 INR 1 Bitcoin = 6455.84 USD
How amazing and cool figures above it are?
That why there are digital currencies booming so fast pace and becoming day to day life par activity for investment and money making just like share market.
Bitcoin is the future digital currency which many countries are looking forward to implementing very slowly in practice as an optional to centralize fiat currencies like dollar, INR, yen, euros and many more.
As now today we see a lot of charges from different banks for payment transfers and transactions at almost 10%. But digital currencies need very fewer fees under 5% for any international payment transfers or transactions.

Now coming towards Bitcoin Wallets.

Bitcoin is the digital currency you cannot have physical wallets like today’s you have. Bitcoins are used to store in software name Wallets. Like Pay Pal, Paytm and many more.
Yes, it’s kind of virtual wallets where you can have all money. Basically for such wallets you will have only crypt key through which you can unlock or lock your currencies for use just like your username and password. Make sure if you are already using such bitcoin wallets then you have to take care and keep your key secret.

Next concept, I am going to put in front of you is Block chain.

Block chains in simple logic you may name it as logs register where each digital bitcoin transaction details stored over block chains. Block chain is also known as decentralized and distributed ledger technology where your cryptocurrencies transaction details are recorded.
Here below are the best links for more information on digital currency.
Coinbase.com Bitcoin.org

Wrapping up now

You now have an idea about Bitcoin. In the upcoming posts I will let you more about such digital currencies.
Plus I want to also enlighten one reason why digital currencies are more famous that's because the transaction remains anonymous. Mean the only sender, and the receiver will know about transaction details with secure crypt keys. Hence make sure you deal with right people for transactions as the whole process is irreversible.
Thanks for being here till the end.
Keep like share and most important support.
Cheers!

Unconfirmed Bitcoin Transaction

Hey everyone, I'm new to reddit so I'm not sure if this is the correct place to ask my question...but it is related to an unconfirmed Bitcoin transaction.
Details- On December 29th, ~11 PM (Eastern Standard Time), I sent ~.5 bitcoins FROM my desktop wallet (Bitcoin Knots) TO my account on Binance (exchange).
When I view my TRANSACTIONS page in my Bitcoin Knots wallet, I see the following information -
Status: 0/unconfirmed, in memory pool Date: 12/29/2017 23:07 To: Binance 19x7XhTaLRWuBZsLfkHRP8yhQPk7q8MAqu Debit: -0.50129628 BTC Transaction fee: -0.00049177 BTC Net amount: -0.50178805 BTC Transaction ID: bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3 Transaction total size: 782 bytes Output index: 0
Here is the BlockChain information related to this transaction - https://blockchain.info/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
And here is the Block Explorer information related to this transaction - https://blockexplorer.com/tx/bb61c6f8a686f21f5679562586056a6b7c28e4427ee2f2db5d9549a59e7615c3
As you can see, the RECEIVED TIME is different across all three (the wallet, the first website, and the second website).
Could anyone explain what might be going on and how to fix this?
Just an FYI...I already performed the -rescan option on my "bitcoin-qt.exe" file. It did some "update database file" or something like that (which was about 2 hours ago) but still no confirmed transaction.
Oh yeah, one more thing, on my TRANSACTIONS page in Bitcoin Knots, the "Cancel Transaction" and "Increase Transaction Fee" is disabled/greyed out when I 'right-click' the transaction record - so, I'm not sure what that indicates either.
Any help is much appreciated!
Thanks!

Giving Coinabul a shot

Been mining bitcoin for a month or so and figured it was time to let some go. The idea of exchanging bitcoin for physical assets is an alluring option so I thought I'd make a small order from Coinabul. So yesterday during the dip (I think we're already dipped below that level as of now...) I made a simple order for 3 American Silver Eagles, and get the invoice.
U.S. Silver Eagle - 1 ounce coin USSilverCoin1Oz 3 ฿0.77 Subtotal ฿0.77 Shipping & Handling ฿0.12 Grand Total ฿0.89 Grand Total to be Charged 0.88812880019033
Ok, so they rounded up, no sweat. Within minutes (time it took for my wallet to catch up the sync) I sent .89 to the provided address. Easy Peasy.
Fast forward to today: I receive a new invoice, saying my order was placed May 15th, as opposed to May 14th as the original invoice states, and now the Grand Total is .93.
I forwarded them the original invoice plus a screen shot of the Bitcoin transaction details to the address they provided and asked them to fix it. And now we wait.
I did read here about problems with Coinabul in the past, but I also saw mixed ideas on whether they were honestly trying to get their stuff together, and 3 Eagles isn't a life changing loss should they fail to deliver.
To be continued..... 8 days later and I have my 3 new ASE's in hand, and they are in great looking shape! Over-all not too bad for a small order... http://imgur.com/Edxaknx

Bitcoin Cash New Transaction type - what are the details?

BTC Cash says it will also have this:
New Transaction Type - As part of the replay protection technology, Bitcoin Cash introduces a new transaction type with additional benefits such as input value signing for improved hardware wallet security, and elimination of the quadratic hashing problem.
https://www.bitcoincash.org/
Anyone know what the details are, so how much of an advantage is:
-input value signing for improved hardware wallet security - is this a significant upgrade?
-elimination of the quadratic hashing problem - was this really a problem?

TigerDirect has the worst customer service and they pretty much stole my Bitcoins.

I first sent a support ticket/email on the website:
 
Date: 10/17/2015 2:46:15 PM
To: "r[email protected]" [email protected]
Subject: Refund Inquiries
Message Sent from: TigerDirect.com website
Order Number : R3105405
Subject : Refund Inquiries
Message : There are a series of things wrong with this order. The shipping/billing addresses are wrong and the "web wallet" I was using could not deliver the BTC within the allotted time provided on this site. I would like a full BTC refund to the following address (seeing as you still have my money), I would like to just make a new order and try sending the BTC from a local wallet.
 
I didn't hear anything from them so I sent another nearly 24 hours after the first, this time "Order Concerns" as the ticket type:
 
Date: 10/18/2015 1:34:55 PM

Really? I copy pasted the order number from your website. Can't see how it can be wrong.

As stated before:
Your website did NOT provide the required amount of time to transfer BTC from a reputable online wallet. Apparently the only way to use your Bitcoin payment service is to have the coins personally on hand or in an online wallet, which would be insecure. If the online wallet were to withdraw BTC and send them to your site in the alloted time, the online wallet needs time to do its own security checks before it can send out the coins, in my case it was an email confirmation I had to wait for before my coins were even sent out to the BTC address your site provided.
If you can't tell, I'm a little heated that around $500 worth of BTC has been in "online limbo" for the last 3 days with no email replies, and now your telling me you can't find my order when it is right in front of me on your website...

I then received no email but the refund did go through... (stupid me) I decided to give them a second chance. I placed a new order on Oct 23, this time a smaller one. It was 2 items, one item (the least expensive item) shipped on time. The second item was marked as "at drop shipper" for over a week. I sent them an email inquiring about the item.
 
Subject : Order Shipping Status
Message : Says it is at a drop shipper, it has been like that for over a week now. If I can't have this item on my doorstep before the end of this week I need a refund in Bitcoin (and I would like the interest you have acquired on my Bitcoin between the time you received the payment and now, otherwise, I would consider you "stealing interest from a customer").
Price of Bitcoin at time of purchase (According to coindeck.com 10/23/2015): $277.46
Amount of Bitcoin received by TigerDirect: 0.823401 BTC
Dollar Value of Missing Item: $144.99
Current price of Bitcoin (11/03/2015): $406.65 (coindesk.com) or $370.36 (bitcoinaverage.com)
Est Bitcoin Value of Missing Item: 0.39148396
This is not the first time I have had issues with your service. I am starting to think I am very unlucky, your company is BS, or someone in company is now actually trying to make my orders not go through (but that would be ridiculous). However, if I get treated like I did the last time I contacted TigerDirect support, I will go public with this whole conundrum just to let the interwebs know how crappy this company is, save them the headache for the holidays...

To: TigerDirect Customer Service [email protected] DO YOU READ ENGLISH?
Was there something unclear about the following?
I WOULD LIKE A FULL REFUND FOR MY "NOT SHIPPED" ITEM, SHIPPING INCLUDED. I WOULD LIKE MY REFUND IN BITCOIN >(WITH INFLATION CALCULATED) SENT TO MY BITCOIN ADDRESS (1GHFv2PSAwRe5cWHD2RjzRim7zfD2KdgHs)
You ass-holes really know how to treat an OEF combat veteran. You steal my money, hold on to it for almost a month stating "We apologize for the inconvenience this may of caused you" and "Please allow 1-2 business days to receive an update" when apparently Fridays aren't a business day. Is there such a thing as inter-department communication in your "company" or is it a bunch of monkeys on typewriters?
I PAID YOU $149.86 in Bitcoin, I expect at the very least $149.86 worth of Bitcoin back.

"I have done a detailed byte for byte accounting of segwit savings for 7 million recent transactions (blocks 410000 - 414660). The segwit discount for these transactions is a factor of 1.86, so segwit gives us effectively 1.86 MB blocks." -Johoe "Bitcoin Hero"

Bitcoin Core: Transaction Details. What does "Status: Open for 202692 more blocks" mean?

First transaction since mining in 2013 and sent all my bitcoin (0.14) to an exchange from the Bitcoin Core wallet but mistakenly set the fee as 1.003 sat / byte and transaction stuck since 28 nov.
Have tried multiple accelerators but no joy. Was hoping it would be dropped by now but no luck, have not been broadcasting with the wallet.
Tried deleting the mempool.dat to abandon but now I have to download 6 years of blockchain to confirm the transaction so the balance shows up in the wallet.
Does the open status relate to dropping (abandoning) the transaction?

Edit: Still no clue about the question in the title.
After some research here is the solution to my problem for any other noobs with a stuck transaction made up of many small inputs.
ELI5 on inputs is think of each input as a denomination of currency like coins and notes For my mining as was paid in the equivalent of loose change with many small inputs.
Each input has a number of bytes so a transaction with many inputs is like paying for something worth $100 with loose change, bulky and slow. I need to create a transaction to another address to convert my change to a note but it will cost a fee to do so.
In Bitcoin-qt i set the walletbroadcast=0 option and deleted mempool.dat.
Downloaded the blockchain again to confirm each input and marked the stuck transaction as abandoned, otherwise I would have ran zapwallettxs option to remove it.
Reason for doing it this way is I still had a couple of unconfirmed inputs from mining i didnt want to lose.
Next i downloaded Electrum and did not import the private key, instead set up the sweep private keys option to consolidate the inputs to a new addreas and set the tx as an rbf with the fee at 50 sats/byte.
Just waiting for confirmation, if no joy in 72hrs will either increase fee or wait for fees to drop.
Can now use original address to claim any btc forks safely.
Hope this helps someone.
