what is blockchain technology ppt

In layman's words, a blockchain is a general ledger that includes all the historical transactions, and each chunk contains several transactions. If the blockchain is a ledger, then chunks are every page of the ledger. The details of the transaction are recorded on a public ledger that can be seen by anyone on a network

Most people do not need to re-create a set of blockchain, but based on the existing blockchain underlying platform to develop their own applications, for similar encryption algorithms, peer-to technology, consensus algorithm and so on only need to have a basic understanding can be, temporarily do not need in-depth research. In the text, there are three main

. The structure of the blockchain ensures that the next chunk will not be validated after each chunk is changed, and the more chunks in the blockchain, the less likely it is to be changed. Unless the hacker has changed all the chunks and all the nodes. He can invade a two node and invade so many nodes at the same time,

Blockchain Enthusiast (qq:53016353) Scrypt was developed by the famous FreeBSD hacker Colin Percival for his backup service Tarsnap. Scrypt not only takes a long time to compute, but also consumes more memory, making it difficult to compute multiple abstracts in parallel, making it more difficult to use rainbow table for brute force attacks. Scrypt is not used extensively in production environments, and

The hashing algorithm is a cryptographic algorithm that can only be encrypted and cannot be decrypted, which converts any length of information into a fixed-length string.There are two characteristics of this string:1. Even if the input value changes only a little, the output hash value will also be poor.2. Only the exact same input value can get exactly the same output value.3. There is no regularity betwe

Symmetric cryptography refers to the same secret key that is used when encrypting and decrypting. Unlike symmetric encryption algorithms, asymmetric encryption algorithms require public and private keys. The public and private keys are a pair, and if the data is encrypted with the public key, only the corresponding private key can be decrypted.Asymmetric encryption is
