Blockchain transaction confirmation time

1. This is not a rigid rule. It has nothing to do with blockchain. There is a relationship between the algorithm of this currency. The confirmation method of each currency is different, so this is not a rigid rule
the confirmation times of bitcoin are different from that of Ruitai coin, Laite coin and doggy coin.

2.

first, define the

blockchain as an open network ledger. It originated from bitcoin and is the underlying technology of bitcoin. In bitcoin transactions, all the information of transaction records will be packaged into a "block" for storage. With the expansion of information exchange, one block links with another, forming a blockchain

Second, the digital currency represented by bitcoin is a point-to-point e-cash system. Among them, every transaction will broadcast to all participants in the network, and it will be recorded in the account book after repeated confirmation, which is called "blockchain". Each participant will have his own account book. In this way, when false information occurs, it can be broken through mutual verification, so as to ensure network security

in the blockchain, every node is equal, and there is no centralized management organization. This "decentralized" feature makes the blockchain do not need to rely on a third party, its operation does not need any human intervention, and it can independently conct self verification. In addition, the network of blockchain is open to the world, and anyone can query data through the public port, so the whole system is highly transparent

In a word, blockchain is a reliable database and a reliable "account book". In the future, it will be applied in cross-border payment, securities, loans, voting, etc. For example, in cross-border payment, with the security of blockchain, you can remit money to the world anytime and anywhere, which saves a lot of intermediate links and high fees

3. Bitcoin network is a global P2P network, which is jointly maintained by all the nodes accessing the network (which can be understood as computers). On average, the global network (not a company or indivial) confirms the transaction every 10 minutes. Bitcoin network miner is to maintain the operation of bitcoin network, to confirm every transaction, can not contact directly< Br > take bitcoin as an example: e to the technical advantages of our platform, the bitcoin you receive will arrive at the account for transaction after one confirmation, and it will take six confirmation (i.e. one hour) before it can be fully arrived at the account and used by you for re payment or transfer out< Br > (Note: e to some special reasons, the confirmation time of indivial transactions may exceed the average time.)< Br > at present, all recharged currencies can be transferred to currency transaction or contract transaction after they have been confirmed by the platform, and the funds can be transferred to the legal currency trading area for sale after they have been fully confirmed.

4. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.

5.

Yes, very much

let's take an example:

get up a little hungry in the morning and go out to buy a pancake to eat

the pancake seller said: 0.000001 bitcoin, please pay

You say: OK. 0.000001 bitcoin has been paid, please confirm

After

1 minute: please confirm

After

2 minutes: please confirm

After

3 minutes: please confirm

After

10 minutes: please confirm

As a result, the boss finally confirmed

just now, because your blockchain fork is confirmed to be invalid, the transaction was unsuccessful. Please pay 0.000001 bitcoin again

you said: mlgb, it's too hard. But I have already eaten it. I can't help it. Pay again. Please confirm

After

1 minute: please confirm

After

2 minutes: please confirm

After

3 minutes: please confirm

After

10 minutes: please confirm

As a result, the boss finally confirmed

just now, because your blockchain fork is confirmed to be invalid, the transaction was unsuccessful. Please pay 0.000001 bitcoin again

you say: boss, I'm wrong. Shall I spit out the pancakes for you

So it can't be used

At present, everyone is short selling

Write an article tomorrow and tell us about it. See my blog: Tech help - Xiaocui says blockchain: how does bitcoin's Curse of wealth justify itself

Transaction mode of bitcoin

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

7. You can log in to the official websites of digital currency exchanges such as fire coin, coin security, biter, etc. Recently, the price fluctuation of bitcoin market is very small, basically in a horizontal state. Experts predict that bitcoin is bottoming out, so we might as well wait and see. If you learn to fry coins, acetoken, a quantitative robot, can learn about it.

8. It's useless to just delete, because there is no solution to the vulnerability
the suggestion is to redo the system, and then find the guardian God to reinforce the system security for you, so as to completely plug the loopholes.

9. It's not the same. Two different varieties can't be the same
