Bitcoin comes from blockchain

1. With the advent of bitcoin, a new technology, blockchain, has come into the public view. What is the relationship between bitcoin and blockchain? The simplest understanding is: blockchain is the underlying technology of bitcoin, and bitcoin is the first generation application of blockchain. Therefore, we often see such a saying that "bitcoin represents the era of blockchain 1.0"
bitcoin is regarded as the first generation application of blockchain technology and the most thorough application of its code testing. However, without bitcoin, there might not be so many people who knew about blockchain now. It can be said that bitcoin has greatly improved the "exposure" of blockchain technology
later, people graally found that the application value of blockchain is far more than bitcoin, but can be applied to many instries to solve the pain points of many instries; The idea of blockchain can also provide a lot of reference for the financial field, which is the real reason for the outbreak of blockchain.

blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btc3. First, open the Tencent Smart Security page

4. At present, there are many such teams, and the blockchain is suitable for all walks of life, but before the early cooperation, we must pay attention to the team strength and effect. The baker chain blockchain that we understand has a good evaluation in the instry, good reputation and good performance in all aspects. The evaluation of the instry is quite high.
5. What is the relationship between blockchain and bitcoin
blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain. As mentioned earlier, the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
if we compare the blockchain to a physical account book, then each block is equivalent to a page in the account book. A new account book is generated every 10 minutes, and the transaction information of bitcoin network is recorded on each page. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain
since the white paper "bitcoin: a peer-to-peer e-cash system" was born, major financial institutions at home and abroad have been competing to study the underlying technology of bitcoin blockchain and seek the practical application of blockchain technology.

6. Bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it
7. Looking at the operation process of blockchain from a transaction:
in bitcoin blockchain, when a transaction is generated through a node or wallet, it needs to be transmitted to other nodes for verification. The method is to encrypt the transaction data by digital signature and obtain a unique hash value representing the transaction by hash algorithm, and then broadcast the hash value to other participating nodes in bitcoin blockchain network for verification. Hash algorithm is to map any length of binary value to a fixed length of smaller binary value, then the smaller binary value 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 that piece, the subsequent hashes will proce different values. It is computationally impossible to find two different inputs hashed to the same value
when a new transaction is generated, it will be broadcast to other participating nodes in the blockchain network first. Each node will put several new transactions into the block, and each node will collect several unverified transaction hash values into the block. Each block can contain hundreds or thousands of transactions
each node calculates the workload proof to decide who can verify the transaction, and the node with the fastest result will verify the transaction, which is a consensus approach. The node that obtains the verification right will broadcast the block to all nodes, and the node that completes the pow the fastest will broadcast its block to other nodes. Each node verifies and connects the new block. Other nodes will confirm whether the transaction contained in this block is valid. After confirming that it has not been repeatedly spent and has a valid digital signature, they will accept the block. At this time, the block will be formally connected to the blockchain and the data cannot be modified. Once all nodes accept the block, the block that did not finish the pow calculation will be invalid, and each node will rebuild a block to continue the next POW calculation
it can be seen that the principle of blockchain is not complicated, and its wide application is natural. Many companies have achieved fruitful results in the process of applying blockchain principles to reality. Like bitcoin, although the ID of the participant is anonymous, the data on the blockchain is public by default. The advantages brought by this openness are unprecedented, such as the ability to resist attacks, the ability to resist the autocratic system of capital control. It is open and transparent while ensuring security, and the account balance of all participants and all transaction records can be seen by people. Until now, we are still surprised by this, because this security method is so novel. However, in the seven-year history of bitcoin, no one has broken this security practically.
