Which consensus mechanism does BTC adopt

1.

The price of a bitcoin soared from more than $20000 to $40000. This can not help but arouse my research interest, or simply understand what bitcoin is, what its mechanism looks like, and uncover its mystery. Therefore, after a simple search of some information and some understanding of the special currency, I sorted out the information on hand< (3) purpose: decentralize, rece risk

(3) only the central server can store and process data in the central network; Large amount of data storage; The central manager has great authority

all servers in the distributed network can store and process data, and each server has equal status, which can store more data and has higher security<
this is the general content of popular science. If you want to know more about it, you can take a look at Nakamoto's paper and the official popular science video below

2. Lightning bitcoin, referred to as LBTC, is a new digital currency proced by lightning team through hard bifurcations of bitcoin, in order to solve the problems of miners centralization and transaction congestion in bitcoin. In addition, lightning bitcoin has nothing to do with lightning network technology, and the improvement of LBTC transaction speed is not achieved through this technology

LBTC was highly forked in block 499999 of bitcoin on December 23, 2017, with a circulation of 21 million, and does not support segwit.

3. Laikelib blockchain infrastructure operation team thinks: blockchain technology can be understood as a public accounting mechanism, which is more a technical solution than a specific proct. The basic idea is to establish a set of public account books on the Internet, in which all users in the network keep accounts and check accounts together, so as to ensure the authenticity and non tamperability of information. The reason why it is called "blockchain" is that the structure of blockchain storage data is composed of a chain of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time, and the chain continues to grow over time
relationship between blockchain and bitcoin: bitcoin used to be one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. It can be said that bitcoin is a "killer application" of blockchain idea. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin.

4. Hash algorithm maps any length of binary value to a fixed length of smaller binary value, which is called hash value. Hash value is a unique and compact numerical representation of a piece of data. If you hash a piece of plaintext and change only one letter of the paragraph, subsequent hashes will proce different values.

5. Blockchain is a technology, and bitcoin is an application of blockchain technology
blockchain has come into the public view because of bitcoin
bitcoin is different because of blockchain technology
