Dallas Bitcoin

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

How to check bitcoin transaction on a Blockchain?

I just sent $400 USD worth of BTC from GDAX to Bittrex. But it's still not showing up on pending deposits on Bittrex account. I'm starting to be concerned. Is there anyway I could check online if it's being processed? I tried blockchain.info, inserted my deposit address, it says no transactions. Please help

Just checked /r/Bitcoin, no mention of high transaction fees or 95k unconfirmed transactions (few hours ago)

Whole first page of /Bitcoin is filled with price pump topics, some guy even dreaming about 330k$ Bitcoin inside one year. It's unimaginable how badly would the Bitcoin network congest on such prices if it cannot withstand current hype and transaction volume. The fact is that Bitcoin is no where near ready for mass adoption and whoever thinks this BTC run vs "shitcoins" is gonna last much longer is gonna get a reality check pretty soon. There are blockchains which can scale with instant speed and no fees, green and so on. Bitcoin is the first one and it showed us the light and we all love it. It's a good store of value since your funds are protected with a lot of hashing power but that's about it. P2p transaction market, m2m transaction market and smart contracts niche will need their own native platforms and they do exist and pretty much should not depend on Bitcoin at all.

Oh yeah, Bitcoin are all about Bitcoin being "the most decentralized" argument, but it seems to me like it's a fact that CZ from Binance is not supporting Segwit and cheaper transaction because of his close ties with Bitmain (most hash rate on Bitcoin), who is also not supporting it and rather has it congested with high fees as it is to milk more money from the users. Those are 2 people manipulating the whole Bitcoin blockchain because of their own personal gains, that's how decentralized Bitcoin is today.

How to check if a bitcoin transaction is correctly signed?

I would like a generic solution to the problem of verifying that a raw transaction is correctly signed. Normally, one can just use bitcoin-cli testmempoolaccept and if the answer is true, the transaction is fit to enter the mempool (and therefore correctly signed).
However, this only works for new transactions to be included in the blockchain, I would like a more generic solution that works for already confirmed transactions and transactions that might spend transactions not yet in the mempool.
With some work I think I could come up with some validation method for P2PKH transactions. For example, for this transaction, I could use something like bitcoin-cli verifymessage 1LBCr8dpZV3fSj3ha1DihMHSvqR3S53jLN , where rawTx can be obtained by bitcoin-cli getrawtransaction and signature from the scriptSig field of the decoded raw transaction. However, this only works for P2PKH transactions. There are probably ways to adapt this to P2SH and segwit outputs but this seems a lot of work to do for every scenario (with different sighash values etc). Isn't there a set of bitcoin-cli commands or some code snippet out there that does this already? Some kind of command that reverses/verifies the output of bitcoin-cli signrawtransactionwithwallet .

Các khái niệm liên quan đến đồng tiền mã hóa Bitcoin. Private key Bitcoin là gì? Public key là gì? Transaction, Address và Ví Bitcoin là như thế nào? Cùng tìm hiểu với tiendientu.org qua bài viết này nhé.

  1. Bitcoin Wallet (Ví Bitcoin)
Thực tế, wallet là chiếc ví tiền vật lý giúp bạn giữ Credit Card, tiền, chứng minh thư… Google Wallet là ví được số hóa thì Bitcoin Wallet cũng có thể hiểu đơn giản như Google Wallet – một ví tiền điện tử – một chương trình giúp bạn quản lý Bitcoin của mình.

Những yếu tố không thể thiếu để cấu thành nên một Bitcoin Wallet chính là Private Key và Public Key – chúng xác định nên tính độc nhất của ví Bitcoin.

Public Key là cái cần phải công khai cho cộng đồng biết để họ xác nhận giao dịch cho chúng ta.
Private Key là cái quan trọng hơn và cần phải giữ bí mật.

Cấu thành nên một Bitcoin Wallet chính là Private Key và Public Key.

Như sơ đồ trên, từ Private Key Bitcoin có thể sinh ra được Public Key, và từ Public Key sinh ra Bitcoin Address (địa chỉ ví Bitcoin). Nên thực tế, ta chỉ cần biết Private Key là đủ, Public Key có thể sinh ra từ nó được. Lưu ý là chiều ngược lại thì không thể thực hiện được.

  1. Private Key Bitcoin (khóa bí mật Bitcoin)
Một Private Key Bitcoin là một chuỗi gồm các chữ số ngẫu nhiên và luôn bắt đầu bằng số 5. Ví dụ như:

5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF

Điều quan trọng nhất cần ghi nhớ chính là:

Mất Private Key, tài khoản sẽ thất lạc vĩnh viễn.

Public Key và Private Key Bitcoin.


Nếu chẳng may mất Private Key thì đồng nghĩa với việc gần như không thể tìm lại được bằng cách suy luận từ Pubic Key, và số Bitcoin trong ví Bitcoin của bạn sẽ thất lạc vĩnh viễn.

Thực tếcó nhiều nghiên cứu đã chỉ ra rằng khá nhiều Bitcoin tồn tại hiện nay là vô chủ, có thể có ai đó thực sự quên, hoặc vốn dĩ họ không biết và đã giao hoàn toàn cho sàn giao dịch, rồi sàn giao dịch bị hack.

  1. Bitcoin Address (Địa chỉ ví Bitcoin)
Bitcoin Address là chuỗi ký tự bao gồm các chữ và số, thường bắt đầu với số 1. Ví dụ như:

1J7mdg5rbQyUHENYdx39WVWK7fsLpEoXZy

Bitcoin Address (Địa chỉ ví Bitcoin).


Bitcoin Address mang ý nghĩa là “nơi nhận” trong một Bitcoin transaction (giao dịch Bitcoin). Bạn có thể tưởng tượng Bitcoin Address cũng giống như địa chỉ nhà người bạn khi ta đặt dịch vụ gửi tặng hoa vào ngày sinh nhật, hay là địa chỉ gửi bưu kiện…

Thông thường, Bitcoin Address là Public Key sau một lần mã hóa, nhưng cũng không nhất thiết phải như vậy.

  1. Bitcoin Transaction (Giao dịch Bitcoin)
4.1. Bitcoin transaction là gì?

Một Bitcoin Transaction (giao dịch Bitcoin) là thuật ngữ mô tả một lượng đồng BTC được gửi từ một hoặc nhiều ví Bitcoin đến một hoặc nhiều ví Bitcoin khác.

Bitcoin Transaction (Giao dịch Bitcoin).

Vì đặc tính minh bạch của blockchain, các transaction đều có thể theo dõi được. Chúng ta có thể kiểm tra:

Ví nào chuyển cho ví nào bao nhiêu đồng BTC tại thời gian nào.

Nhưng vì tính ẩn danh, không ai biết được chủ sở hữu đằng sau những chiếc ví Bitcoin đó. Cũng như tính không thể sửa đổi, các Bitcoin Transaction (giao dịch Bitcoin) một khi đã được xác nhận thì không thể thay đổi được nữa (trừ phi ví người nhận chuyển BTC lại cho ví gửi).

4.2. Check Bitcoin transaction như thế nào?

Để check Bitcoin transaction (check BTC transaction), bạn truy cập vào https://www.blockchain.com/explorer, nhập Bitcoin Address của ví Bitcoin cần kiểm tra, sau đó nhấn Enter.

Check Bitcoin transaction.

Thông tin của chiếc ví đó sẽ được hiển thị đầy đủ, gồm số dư (số lượng BTC hiện có) cũng như liệt kê tất cả các giao dịch (gửi, nhận). Nếu có unconfirmed transaction blockchain nghĩa là người gửi đã chuyển BTC cho người nhận nhưng giao dịch chưa được xác nhận (confirmed).

  1. Tóm tắt
Bitcoin Wallet là một ví tiền điện tử giúp bạn quản lý Bitcoin của mình.

Private Key và Public Key là hai yếu tố làm nên tính độc nhất của ví Bitcoin.

Public Key là cái cần phải công khai cho cộng đồng biết để họ xác nhận giao dịch cho chúng ta.
Private Key là cái quan trọng hơn và cần phải giữ bí mật.

Các khái niệm private key, public key, transaction, address trong Bitcoin.

Bitcoin Address mang ý nghĩa là “nơi nhận” trong một Bitcoin transaction (giao dịch Bitcoin). Bạn có thể tưởng tượng Bitcoin Address cũng giống như địa chỉ nhà người bạn khi ta đặt dịch vụ gửi tặng hoa vào ngày sinh nhật, hay là địa chỉ gửi bưu kiện…

Bitcoin 2010 vulnerability

Hello I am entering in this world and always curios and curious to analize vulnerabilities. Here there is the 2010 bitcoin vulnerability which I didn't full understand, can someone help me to understand?
https://bitcointalk.org/index.php?topic=822.0
The "value out" in this block #74638 is quite strange:

This could be a serious problem. Bitcoin's printblock also shows it:

I have a serie of questions:
  1. What is this language? which kind of language is it?
  2. the POCO i this:
''Essentially, the code for checking Bitcoin transactions did not work if outputs were so large that they overflowed when summed, and a hacker figured this out and took advantage of it. There is supposed to be a fixed maximum supply of 21 million Bitcoin, but the hacker, in a single transaction, created 8,784 times more Bitcoins than ever should exist.''

What does it mean ''did not work if outputs were so large'' ? The output of what?
so large that they overflowed when summed ...
what does this mean? can you make an example to let me understand?
The sum of what + what? And why does this sum caused a bufferoverflow? A buffer overflow isn't it when for example there is an array and then there is no definied lenght for the array and you put in more than the array may own? In this case from what is the buffer overflow caused by?
Also interstead in what does this string mean:
vMerkleTree: 012cd8 1d5e51 618eba
what does this mean?

Unsarcastically, Bitcoin Cash forked for this reason. Check out the project. Perhaps storing all transactions on chain will be to heavy, but it is working today as cash (<$0.01 transaction fees) and there is evidence technology will scale to accommodate the growing blockchain size.
If that is wrong, perhaps a second layer on Bitcoin (BTC) is the solution, but it appears years away from being as usable as bitcoin was/is before the blocks started filling up.
