Blockchain before bitcoin

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. Blockchain is one of the technologies of bitcoin, which can be understood as cloud database.
4. No, after all, it's a new movie
5. Now we can use blockchain technology to finance. In the early stage, we can package roadshows to attract angel investment. In the later stage, we can issue digital currency online transactions to finance in the trading market. The cycle is generally 1-3 months and the cost is low. At present, it is a very safe and convenient way to find blockchain teams with hard technology and rich channels.
6. Manual drilling and blasting or mechanical drilling and blasting method are used for drilling and blasting construction. In actual construction, blasting operation is carried out in strict accordance with the blasting layout diagram provided by the blasting engineer and the corresponding blasting parameters. Excavation blasting (at the same time, advance geological prediction of construction) → mucking → initial shotcreting operation → section clearance detection → anchor rod, steel mesh Monitoring and measuring point embedding operation → erection of steel frame / grid steel frame (construction of embedded parts at the same time) → re spraying concrete operation → initial support clearance detection → waterproof and drainage system operation → reinforcement operation → formwork trolley in place → lining concrete operation → measurement operation
7. Hello, sell the virtual currency to the people who need it. Remind the owner, network private transactions must be careful, don't be cheated.
8. No, bitcoin was born at the end of 2008, and blockchain technology was well known 14 or 15 years later. It is the large-scale application of bitcoin that makes people pay attention to the underlying technology of blockchain. If you are interested in bitcoin, you can go to the okex exchange to open an account and make a fixed investment when you have spare money. Thank you for adopting and approving my reply
9. 1. Blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain
2. The transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
3. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain.
