Explanation
In order to clear White said:
Private-public key address how to get Bitcoin wallet Exchange
Simple and crude, do not speak principle , do not speak of principle , do not speak principle
Theorem (fog
He said do not speak principle, it is when it is a theorem
私钥 →公钥 → 地址
Direction of the arrow, the foregoing known, the latter can be calculated, not vice versa
Therefore, 私钥 the most important!
Their long-sawed:
私钥-KwYC54hbaH6X5CrCfDK19oyJd2d1ivnSakbJxrW4ENbi2E2bJkbN公钥-很长不方便记，所以都用地址地址-1KS3jJNCLDQpVGCXP8hteYuaCukHEtsoHV
How Bitcoin is traded
One 地址equivalent of an account, credits by bit 地址transfer each
Anyone can to a 地址transfer, but to spend 地址the money, you must know私钥
This is why 私钥the most important
Bits recorded on the block chain is credits 地址transfer records between
There transfer records, you can calculate 地址how much money
What is the wallet
A 地址is an account under the name of each person may have a lot of accounts
But there is a 地址will there is certainly a私钥
Purse is to help you manage your private key
Purse generally about features:
Help you calculate how much money you hold (that is calculated from the block chain to address how many there bitcoin)
- Backup, if you lost your phone or computer, backup your private key will be able to get back
Transactions, transfers to other address
Why does everyone have a lot of addresses, instead of one:
No one can calculate a block from the chain 地址of transactions, if you have been using one 地址, your privacy might storm drain
Is generally not from 地址own this calculate the 地址Who, but if you use a long time, such as buying something from a URL with this 地址transfer, and it can be 地址and who you are linked to, you know who you are the
Because 地址you can come out of nowhere, anyone can easily generate (talk back)
So transfers are many different addresses, but these things you do to help wallet, white may not feel
You may be worried about the safety of wallet, but most of them are safe, provided that famous wallet, purse official website generally recommended safety
How to generate address
Anyone can generate a 私钥, thereby generating地址
私钥256 is a binary string composed of 0 and 1 in nature, then encoded as a string
This 256 0 and 1 are random, so you continuously toss a coin 256 times, you can get an address
Here randomly is very important, if you just like to write a 256 with 0 and 1, and that you have the same habits might also like you to write 0 and 1, equal to your private key is people know.
No one will go to flip a coin it should be, we are generating software 私钥, the software has its own random method
This is a secure website: www.bitaddress.org
Depending on your mouse position sampling to generate a random私钥
Cold wallet:
If you saved URL is generated in a secure environment offline私钥
And only you know, this 私钥is a cold wallet
As long as you do not disclose, no one knows, as long as you can generate a private key known only to you, no matter what means, are considered cold wallet
Wallet with the common market has been very safe
Exchange
If you do not have money in the circle of acquaintances, you can buy to exchange bitcoins
Exchange and the stock exchange that functions almost
You buy bitcoins are on top in the presence of the exchange, can be put forward, but there are fees
Exchange does not it give you a private key, which means you can only put forward by the official Bitcoin way, if the exchange on foot, and you did not coin
Security Exchange are well-known: I generally use fire coins (coins fire play money 17MaxVm9Zm8WQfHrrgA2LVzuEDdSL6AZVN)
