说起助记词，其实它就是明文私钥的另一种表现形式，它最早是在BIP39的提案中提出的，助记词的主要目的就是为了帮助用户记忆复杂的私钥。我们知道，钱包的私钥一般都是由64位的哈希值组成的，而助记词仅仅是由12、15、18、21个单词构成，这些单词都是从一个固定词库中取得的，它的生成顺序也是按照一定算法而来，所以我们也不用担心随便输入12个单词就会产生一个地址。我们经常听人说要备份好助记词，那么究竟备份助记词是什么意思？下面就让小编说一说。
Speaking of assistive notes, it is actually another expression of the explicit private key, which was first proposed in the BIP39 proposal, the primary purpose of which is to help users remember complex private keys. We know that wallets are typically composed of 64-bit hickeys, whereas assistive words are made up of only 12, 15, 18, 21 words, all of which are derived from a fixed vocabulary, and are generated in a certain number of algorithms, so we don't have to worry about entering 12 words in order to create an address. We often hear people say that they are backed up, so what do they mean?
用过钱包的用户都知道，在使用钱包之前，会让你备份12个单词，在备份期间不允许截图操作，并且不断强调这12个单词非常重要，最好用物理方式备份，备份时身边不要有任何人。
Users who have used wallets know that, before using wallets, you will be allowed to back up 12 words, not allow screen operations during backup, and constantly stress the importance of these 12 words, preferably in a physical way, with no one around them.
众所周知，在区块链世界里，只要保留了私钥，就能解锁账户，但是通常来说私钥是由64位的很长的字符串组成，如果我们想要创建100个账户，那我们就要记100个私钥，记录和保存成本是非常大的，况且，在记录海量的私钥的过程中，可能还会出现地址和私钥匹配不上的问题，或者记录时粗心大意写错字母的问题，等等，总而言之，出错的概率是很高的，由于数字货币这种“只认私钥不认人”的特点，这些小的错误很可能导致资产无法找回。
It is well known that in the block chain world, accounts can be unlocked as long as private keys are retained, but typically the private key is made up of a long 64-digit string. If we want to create 100 accounts, then we have to keep 100 private keys, with very high recording and preservation costs. Moreover, in the process of recording the private key of sea volume, there may also be problems with the matching of addresses and private keys, or with careless miswriting of letters at the time of recording, and so on. In short, the probability of error is high, because of the & ldquao of digital currency; the non-identification of private keys only & rdquao; and the characteristics of these minor errors may well lead to assets not being recovered.
由于区块链公有链的公开的特性，链上的所有转账记录任何人都可以查到，如果同一个账户关联的收入支出太多了，最终是可以摸出一些线索，把你和一些交易给匹配起来的，所以为了隐私考虑，我们的很多隐私业务通常会创建出新的账户来进行交易。
Because of the open nature of the public chain of the block chain, all transfer records on the chain can be traced to anyone. If there is too much revenue spending associated with the same account, it is eventually possible to find some clues to match you and some of the transactions, so many of our privacy operations usually create new accounts for trading purposes for privacy reasons.
聪明的开发人员为了解决上述问题，提出了Bip39协议。Bip39协议的全称是Bitcoin protocol，最初是由比特币社区的开发者提出，后来被其他的主流区块链项目所认可，继而成为了整个行业共识和规范。
Smart developers put forward the Bip39 agreement to address the above issues. The Bip39 agreement, referred to as Bitcoin Protocol, was originally proposed by developers of the Bitcoin community and later endorsed by other mainstream block chain projects, and then became the industry consensus and norm.
BIP39协议的核心是，由12个单词来确定自己的账户，12个单词会生成很大的种子，从2的256次方选出一个数，由于随机生成的数是很大的，所以完全不用担心生成的12个单词会重复。
At the core of the BIP39 agreement is that 12 words determine their accounts, 12 words generate large seeds, one number is selected from two 256 parties, and since the random number is large, there is no fear that the 12 words generated will be repeated.
虽然助记词和Keystore都可以作为私钥的另一种表现形式，但与Keystore不同的是，助记词是未经加密的私钥，任何人得到了你的助记词，可以不费吹灰之力的夺走你的资产控制权。所以在用户在备份助记词之后，一定要注意三点:
While the notes and Keystore can be another expression of the private key, unlike Keystore, the notes are private keys that are not encrypted, and anyone who gets your notes, can take control of your assets without saying anything. So after the user has backed up the notes, three things must be noted:
1.尽可能采用物理介质备份，例如用笔抄在纸上等，尽可能不要采用截屏或者拍照之后放在联网的设备里，以防被黑客窃取；
1. To use, to the extent possible, physical media back-ups, such as pens on paper, and not to use screens or photographs to be placed in networked equipment to prevent hacking;
2.多次验证备份的助记词是否正确，一旦抄错一两个单词，那么将对后续找回正确的助记词带来巨大的困难；
2. Repeated verifications of the correctness of the supporting notes for the backup, which, if one or two words are wrongly copied, will pose great difficulties for the subsequent recovery of the correct supporting notes;
3.将备份后的助记词妥善保管，做好防盗防丢措施。
3. Take good care of the backup assistive notes and take anti-piracy and anti-fouling measures.
PS：用户可以使用备份的助记词，重新导入imToken，用新的密码生成一个新的Keystore，用这种方法来修改钱包密码。
PS: Users can re-import imToken using backup assistive words and generate a new Keystore using a new password to modify the wallet password.
正是因为助记词的出现，我们才能对每一笔交易都创建一个新的账户，而这些账户里面的钱也可以进行自由的转移。要知道，在区块链世界，我们记住了12个简单的助记词，就等于间接记住了所有区块链上的资产，它就像我们现实生活中的身份证一样，非常的便捷高效。有了助记词之后，普通用户的使用成本可以说是被大大的降低了，并且让我们普通人的使用体验更加的友好。
It is because of the helpword that we can create a new account for every transaction, and the money in these accounts can be transferred freely. You know, in the block chain world, we remember 12 simple help notes, which indirectly remember the assets on all the block chains, which are as easy and efficient as our real-life identity cards. With the help, the cost of ordinary users can be said to be significantly reduced and our use experience more friendly.
