What is the Digital Signature? Outside correspondence Signed at the bottom of the page where the documents are being written
\nConfirmed Look at the signature. This is a self-written book
\nThey confirm that. The same can be said for digital mail
\nYes. You have to enter it with a private key.
\nEncrypt the text with a private key and attach the encrypted password to the original text
\nOf course. This method does not hide the message. The sender is the original author
\nWhether you send it yourself or not. The authentication is not exactly the same as the original submission.
\nRecipients can use the Public Key to check the accuracy of the original text.<\/p>\n
In the example, the text Hello with signature is signed with the private key
\nYou will see a message called Signed Message.
\nThe next step is to sign the Signed Message. Original text Public Key
\nIt will check if the given value is correct.
\nIn this way, digital correspondence, You have to sign the documents. With Private Key
\nSign and verify with Public Key. Do these things yourself from start to finish
\nYou do not have to. This is just an example to make it more visible. In practice, the relevant software
\nYou will be able to sign in with just one click.
\nIf you want to learn more, you need Digital Certificate or Certification Authority
\nPublic Key Infrastructure is a PKI related topic
\nWe have to study. It does not take much to understand how Bitcoin works. Public
\nOnce you know about Key Encryption and Hash, you can move on.
\nIf you’re a little confused by this, encourage yourself to give it a try
\nYes. Because it can be clearer in practice.<\/p>\n
Receiving an important piece of information from a stranger
\nHow do you determine if the information is accurate? That’s something to think about. Because I closed my eyes and believed
\nNo Outside, we have to find out who that person is. The information he provides
\nYou may need to check with an expert.
\nIn the computer system, such strangers, Information from an unknown source
\nConsensus algorithms are used to determine accuracy. Proof of Work,
\nProof of Stake, Proof of Authority, Proof of History, Proof of Capacity
\nYes. Here is a summary of some of these concepts:
\nLet me just say that.<\/p>\n
Proof of Work If you can do it, give it to him
\nIt means believing in the facts. Math as a mathematician
\nTo verify the identity of the person submitting the educational information
\nIt’s kind of like putting a sentence into practice. He reports only if he can calculate
\nWe will accept the information as correct.
\nProof of Stake means trust if you can prove your ownership
\nIn a sense. If a bookstore offers a deposit, she’s going to a stranger
\nBooks can be borrowed at will. If the book is not returned, the deposit will be forfeited
\nBecause you can follow. The same goes for Proof of Stake. A property is guaranteed
\nIt is a way of acknowledging that what he said was true.<\/p>\n
