Satoshi Nakamoto was born in 2011. He sent his last letter on April 26, Bitcoin
\nThe Core has already left the project.
\n“It’s not a project held by a spy, it’s created by the public,” he said.
\nWe want to make it a project, “said Gavin Andresen of the Bitcoin Core Project.<\/p>\n
1. Bitcoin Technology Ideas
\n2. With Bitcoin Core software
\n3. Bitcoin network needs to be different.<\/p>\n
Bitcoin technology idea is a white paper written by Satoshi. That technology
\nCryptocurrency sharing is a free and open source digital currency system.
\nYou can create a lot. In practice, there are many such creations.
\nBitcoin Core is a project that implements the Bitcoin idea
\nIt’s one. This is the first project created by Satoshi Nakamoto himself. This project
\nBecause its source code is open source, it can be trusted by anyone. Written
\nExamine the code; You can do the retrieval. The address on the next page
\nYou can see. The Bitcoin Network is a repository of payment records
\nIt can be said that it is a computer network. A computer; A person At an organization
\nIt is not stored, it is distributed to many people in the Bitcoin network
\nOf course. This record is also shared by a person. It is not held by an organization.<\/p>\n
So Bitcoin is not controlled by one person. The idea is people
\nIt can be measured. The project is also open source. The information is also on the network
\nIt’s completely free from control because it is co-managed by all stakeholders.
\nThat way, everyone would be able to access it, so everyone should be able to access the information stored.
\nWhat if you do? Feel free to keep valuable money with everyone
\nCan I have it? You can not see it in the circle because it is completely different from the traditional R.
\nIt will be a very difficult concept to understand. Of this book
\nThe purpose is to explain it. We will continue to study.<\/p>\n
Traditional digital payment systems such as Mobile Money and Pay can be used at banks or
\nStore information under the supervision of a financial services organization
\nAnd they work. Bitcoin is no longer such an organization, and many of me
\nIt distributes and operates data on that network.
\nIn doing so, you will be able to securely transfer and transfer information.
\nIt uses a combination of digital encryption techniques known as cryptography.
\nCryptocurrency is also known as Cryptocurrency because it works using Bitcoin
\nTo understand how it works, you need to know how these crypto technologies work.
\nHere are some things to look for when selecting yours.<\/p>\n
Simply put, encryption is a simple form of encryption. Write confidential messages
\nIt is written using code that only the author and the person who knows the letter can recognize.
\nThe most basic example is location values \u200b\u200brather than ABCD letters
\nLet’s say you replace it. A is 1, B is 2, C is 3 and so on. So Hello in the letter
\nIf you want to write “8 5 9 9 15” The middleman enters the code 8 5 9 9 15
\nI do not know what the word “find” means, but the recipient decides the value of the English word location If you know that you are using it, you can decode and get the original text.
\nThis is very easy. Find the value of the location plus the value of the mailing date
\nIf you set it to, it will be a little bit more. If you send it on Monday, the value will be 1
\nMust be combined with If you send it on Tuesday, you have to multiply the value by 2. So Hello Tuesday
\nIf you want to write the text “10” 11 11 17 Cracking codes
\nThey look for the pattern in the hidden code and come up with a solution. Letters written on Tuesday
\nOnce you notice that the patterns are similar, you will know the coding solution.<\/p>\n
The next step is to create a random key value that is known only to the sender and the receiver
\nIt is also possible that For example, set the value 5-7-1 to the key and 5 to the key
\nMultiply Subtract 7 Suppose you have to add more than one to each one. That’s why I wrote Hello
\nIf you write it, it will be 33 19 38 39 68.
\nThe actual calculations would be much more complicated. AES (Advanced
\nEncryption Standard), IDEA (International Data Encryption Algorithm)
\nMany articles have been published in various research papers. Here it’s
\nThese algorithms will not be included, but are typically encrypted.
\nI would like you to know the meaning of R and Key, which are included in the text.
\nAlgorithm \u2192 Multiply by one word
\nKey 5-7-1 \u2192
\nIn the example above, multiplication is more than one word
\nYes. If you change the code, You can use this algorithm to decode.
\nHowever, even if the algorithm used does not match the key, it will not be displayed. Given example
\nAccording to the pain, the key is 5-7-1. So we know the algebra of over multiplication and division
\nEven if you do not know the 5-7-1 key, you will not be able to decrypt the script.<\/p>\n
This type of key-based encryption technology is called symmetric encryption
\nSo, they are confused. Bitcoin stands for ECDSA (Elliptic Curve Digital Signature Algorithm)
\nHowever, Al Gore is used. It is not Symmetric Encryption. Public Key
\nThis is a technology called encryption. Also known as Asymmetric Encryption.<\/p>\n
The problem with simple symmetric encryption is that the sender, Both hands need to know the key
\nSo, if you do not have a key that you both know, you will not be able to send it. So more
\nAs an invention, a key for typing and a key for typing; The technology that goes hand in hand
\nThey invented the technology and called it Public Key Encryption.
\nThis technique is similar to a two-pronged lock, although it has only one lock. Distinctive
\nYou can only unlock it by locking key A with key A. Conversely, the key B
\nYou can only unlock it with key A. This concept is often overlooked
\nPlease check again. Use the first one, which has two keys and a key
\nYes. Use the second one to restart.
\nIn this sense. Public Key Encryption also has two keys: Public Key and Private Key
\nYes If you create a password using the Public Key, you can only recover it with the Private Key.
\nThe Private Key can be stored securely by yourself. Distribute the Public Key to me
\nYou can share. When someone sends a message to you, send a message with a public key
\nYes. In the meantime, someone else could not access the password with a public key. To me
\nOnce there, you can retrieve the password with your private key.<\/p>\n
It is also planned to make this concept visible to the naked eye. Some issues
\nBecause it is clearer when you look at it. See this address
\nhttps:\/\/eimaung.com\/crypto
\nSo, there are three tests: Symmetric, Asymmetric, and Hashing. Symmetric Encryption
\nTo test, enter the source code with the secret key and click Encrypt 0
\nTherefore, the code will be in Cipher Text on one side. In the source text and in the Key field
\nYou can try different values.<\/p>\n
For example, using the key bitcoin101 to encrypt the message Hello b0bcf811f5
\nI got back the password. Decrypt b0bcf811f5 at any time with bitcoin101 key
\nIf you do it again, you will get back the original Hello text. You can also try asymmetric.<\/p>\n
However, clicking the first Generate Keypair 0 will generate the Private Key and Public Key
\nYes. It has to be copied. When done, go to Encryption and enter the original text and Public Key
\nClick Encrypt and you will get the encrypted code automatically.<\/p>\n
When done, go to Decryption, enter a private key and password, and click Decrypt.
\nSo you have to go back to the original text. That way, if you have something to send to you, send it with a public key
\nIf you have a private key, you will know the original text. Many people want to make a secret letter
\nYou no longer need to know your private key for
\nThis is a very important system for technological security and should be used everywhere
\nYes. Bitcoin came into being because of this system. Another important
\nLet me tell you about a natural Hash.<\/p>\n
You should also go to Hashing and try it in one go. Enter data in the Data field
\nEach time you enter a value, you will see the following hash value change.<\/p>\n
What a hash is like? Mix In pieces<\/p>\n
Squeeze to shrink. Divide into two parts. Mix and repeat the final result
\nIt kind of gives out. This returns the hash signature as a result.
\nSo, it is important to note some important features.<\/p>\n
1. The hash that comes out of the final batch distribution, no matter how much data is given
\nThe size is the same. In the example, the result hash is always 64 characters long<\/p>\n
2. If the given data is the same, the return hash is always the same. Get it back at random
\nOf course not. Because the original data is distributed and returned, the result will always be the same if the data is the same.
\nThis concept is also known as Digital Fingerprint. Fingerprints vary from person to person
\nIf the given data is different, the result hash is different. But looking at the fingerprints, this person is right
\nYou can confirm that.<\/p>\n
3. The resulting hash can not be restored to the original data. Therefore, this is not the same as encryption. Encryption is the process of encoding the original text. You can revert to the original text. Hash goes one way. Original Data. Once the hash has been changed, it is no longer possible to recover the original data from that hash. It is as if a pot smashed and that the original pot could not recovere from the cracks. If the distribution is not dark.<\/p>\n
If it does not spread, look at the cracks. Porcelain pot? You can only guess. Yes Even if the distribution is mixed and mixed, it will not be possible to predict even that. They want something that is unpredictable for security reasons. Look at the fingerprint.<\/p>\n
