The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"

blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block

blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized

characteristics of blockchain Decentralization:

decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center

in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes

with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment

but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over

When bitcoin nodes connect with each other, they will get transactions they don't have from each other. But because bitcoin has accumulated a large number of transactions for a long time, it is very difficult for two nodes to compare which transactions you are missing / which transactions I am missing one by one

to solve this problem, Nakamoto Tsung invented the important technology of block chain. Nodes use blocks to synchronize transactions, which ensures the data consistency of all nodes, and ensures the uniqueness of the blockchain by competing for block packing rights (that is, mining)

① a block and blockchain
a packet formed by a transaction over a period of time is called a block. On average, bitcoin generates a block every 10 minutes, and each block is linked to the previous block to form a blockchain

② the transaction data is synchronized with the block as a unit
the block is numbered from 1, so after node a connects with node B, it is convenient to synchronize the transaction data as long as the block number height of both parties is checked. For example, if node A's own block height is 100 and node B's block height is 110, all it needs to do is request B to synchronize the 10 blocks 101-110<

③ reward for packed blocks
in order to ensure that there are nodes to pack bitcoin transactions, bitcoin rules stipulate that nodes of packed transactions will receive bitcoin as reward
A. part of the package reward comes from the transaction fee paid by the transaction creator (100-1000 transaction fee per KB)
B. the other part comes from the initial distribution of 21 million bitcoins. At the beginning, the reward is 50 bitcoins for each block. After that, the reward will be halved for every 210000 blocks (about four years). Until about 2140, the reward for each block is less than 1, and the total reward for each block is 21 million bitcoins, This is the source of the total amount of 21 million bitcoins (2099999.97690000 to be exact)
after 2140, the package reward will only come from the transaction fee paid by the transaction creator<

④ competition for block packing right
node packing transaction only needs to consume very low-cost network and computing resources. The existence of packing reward (at present, the packing reward for each block is 25 bitcoin, about 40000 yuan), makes a large number of nodes want to pack transactions. In order to ensure the uniqueness of the blockchain, bitcoin rules stipulate that nodes use a method similar to "coin tossing" to compete for the right of transaction packaging. Nodes constantly toss coins. Whoever first throws the results that meet the rules will get the right to pack the transaction in this block, as well as the package reward of this block

Blockchain is an important concept of bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a bitcoin network transaction, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

the data on bitcoin blockchain, which we call the data on the chain, generally includes: bitcoin active address, new address, continuous active address, reactivated address, transaction volume on the chain, number of transactions on the chain, TSP, transaction transfer fee on the chain, large amount transfer, mining difficulty and other data

we generally query the data on some blockchains through the blockchain browser, Bitcoin's more commonly used blockchain browsers are:

Finally, I saw someone separate blockchain from bitcoin

in fact, bitcoin and blockchain are not the same thing at all. Many people just have a chivalrous understanding

this is what a 36K article says. I think it is very objective

in bitcoin and blockchain, "network effect" is a misunderstood concept, because its internal elements are difficult to be clearly depicted. The internal factors of network effect are multi-dimensional, and not so many people can directly experience great network effect. As consumers, we are only users of this kind of network effect. We think we can understand the network effect from the outside, but it is not enough to judge whether the network effect exists

when we discuss the ecosystem of bitcoin and other cryptocurrencies, we always touch on the topic of "network effect". Many people will misunderstand this and even claim that bitcoin's network effect is the most powerful because of its liquidity and ongoing mining activities. So let's go back and see what "network effect" is

as far as I know, the summary of "network effect" by USV is the most complete:

scale: must be very large

mutual connectivity: in a network, each group or system must have interoperability (this is the basic requirement)

User Participation: at least every day (or every week), a certain percentage (30%) of users will come back for reuse

User Experience: it must be unique, original, and can create some new value when users use it

network effect: when new users are added, the service value of each original user will increase, and the value of the network itself can further increase

defensive: with the growth of the service itself, the value of new users will increase, and the entry threshold will graally strengthen

profitability: when the whole network matures and operates, one or several parts can become a sustainable economic base

if you evaluate bitcoin correctly, you will find that it is still leading as cryptocurrency, its consistency is steadily improving, and the blockchain platform is graally developing. However, there are still many blind spots in its future, such as large-scale ability, and the number of daily active users is not enough. It's too early to judge the network effects of bitcoin and blockchain

don't forget:

without users, there is no network effect
