BTC gateway interface of ICBC
Suppose you understand the blockchain. To put it simply, the blockchain generates a new block every ten minutes to store all the transaction information in the blockchain. This block is equivalent to a network account book, which correctly time stamps all the transactions of the whole network in the past ten minutes. The question is who will build it? The "miner" on the blockchain is to compete for the bookkeeping right of a block in the past ten minutes. The rule of competition is to solve the sha256 problem while correctly bookkeeping. Who can prove that his computer has the fastest computing power can compete for the legal bookkeeping right of the block in the past ten minutes. This is the "mining" process. In the bitcoin blockchain, miners who dig mines can get certain bitcoin rewards. Therefore, miner's more essential function is "bookkeeper"
in his bitcoin white paper, Nakamoto describes in detail the process of establishing the credit system:
Step 1: in order to make the whole network recognize effective, every transaction must be broadcast to each node (node: miner)
Step 2: each miner node should correctly stamp each transaction in the ten minutes and record it in that block
Step 3: each miner node should compete for the legal bookkeeping right of this 10 minute block by solving the sha256 problem, and strive for the reward of 25 bitcoins (50 bitcoins every 10 minutes in the first four years, decreasing by half every four years)
Step 4: if a miner node solves the ten minute sha256 problem, TA will publish all the time stamped transactions recorded in the ten minute block of TA to the whole network, which will be checked by other miner nodes in the whole network
Step 5: other miners in the whole network check the correctness of the block's accounting (because they are also stamping the time stamp for accounting, but they do not compete for the legal block's accounting right, so there is no reward). If there is no error, they will compete for the next block after the legal block, thus forming a single block chain of legal accounting, That is the general ledger of bitcoin payment system - blockchain
generally speaking, each transaction must go through six block confirmations, that is, six ten minute bookkeeping, before it can be recognized as a legal transaction on the blockchain. The following is the accounting format of bitcoin:
so the so-called "bitcoin" is such a billing system: it includes the owner using the private key to make an electronic signature and pay to the next owner, and then the "miners" of the whole network stamp the account to form a blockchain Network)
if you want to learn more about blockchain information, it is recommended that you use Baijia, mustard circle and other popular B circle media. The amount and richness of information are more and better than those on the general network. If you want to ask technical questions, you can take a look at the links below, hoping to help you with the
Web links
the bank's online banking can open online inquiry, transfer, online shopping and payment at the same time, or one of them can be opened separately
if you open online inquiry, you can choose to register online directly or call the counter of the outlet to open it.
you can only query the account information through online banking, or handle the transfer between your own online banking accounts
if you open online shopping (BTC), you can choose to sign up online (pay less than 300 yuan) or open it at the counter of the outlet
online shopping (e.g. Taobao, paipaipai, etc.) and payment of public utilities (e.g. water and electricity, mobile phone, etc.) can only be done on the websites associated with bank payment
if you open online transfer, you must open it at the counter of the branch.
you can transfer your non online banking account and other people's accounts<
password card and USBKEY (U shield) can be selected in terms of security and confidentiality, only one of them can be selected:
password card can only be used for single payment of less than 1000 yuan, daily cumulative payment of less than 5000 yuan, and historical cumulative payment of less than 20000 yuan. At present, it can be applied for free
u-shield is a high-density e-Cert, which is connected to the computer like a U-disk when paying. It's like adding more locks to online banking, which makes it more secure. Therefore, there is no limit on the amount of transfer or shopping. You need to install software and charge a one-time fee (about 60 yuan at present, which is already 50% off)
when dealing with online banking external payment business, customers who use login password and payment password need to protect your card number and password, ensure the security and reliability of the computer logging in online banking, update anti-virus software regularly, download patches in time, do not open unknown programs, games and e-mails, and maintain good online habits; If you can't do it completely and don't worry, using u-shield is your best choice. As long as your login card number, login password, u-shield and u-shield password are disclosed to one person at the same time, you can safely use online banking
from a technical point of view, u-shield is a tool for e-signature and digital authentication of online banking. It has a built-in micro smart card processor and uses 1024 bit asymmetric key algorithm to encrypt, decrypt and digitally sign online data to ensure the confidentiality, authenticity, integrity and non repudiation of online transactions
e-bank password card is equivalent to a dynamic e-bank password. The password card is printed with a number of strings in the form of matrix. When customers use e-banking (including online banking or telephone banking) for external transfer, B2C shopping, payment and other payment transactions, the e-banking system will randomly give a group of password card coordinates, and customers will find the password combination from the card and input it into the e-banking system according to the coordinates. Only when the password combination is correctly entered, the customer can complete the relevant transaction. This password combination is dynamic, users input different passwords every time they use it, and it will be invalid after the end of the transaction, so as to prevent criminals from stealing funds by stealing customers' passwords and ensure the security of e-banking
password cards are easy to be stolen in the form of scanning, taking photos (especially now mobile phones can take photos), ing, etc. password cards need to be kept to ensure safety
it's difficult to find the U shield. If the U shield is lost, it's easy to find it, and it's less likely that the login password, U shield and U shield password will be leaked to one person at the same time

note: 1. Self service registration is under "personal online banking login" in the upper left corner of the webpage
2. It is not recommended to bind the bank card for online shopping. If the card number changes e to the loss or damage of the bank card, it will bring inconvenience to your use
