Blockchain quantum

1. If you find something wrong, it's the right way to get out early
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

2. Introction: quantum blockchain technology is a professional Internet technology service provider integrating computer software and hardware research and development, digital currency proction and asset management. Its main business is to mine the most core value digital currency in the world, especially bitcoin. It belongs to quantum blockchain Technology (Guangzhou) Co., Ltd
legal representative: Xu Rong
time of establishment: April 28, 2018
registered capital: RMB 10 million
enterprise type: limited liability company (invested or controlled by natural person)

3. 1. Blockchain is an anti tampering, shared and traceable distributed ledger technology. Anti tampering lies in that the modification of a single node can only be recognized through the consensus of other nodes; Traceability means that the whole account book of the blockchain can only be written in, not deleted, and all modification records will be left marks on the whole chain; Sharing means that the account book of the whole blockchain is transparent to multiple nodes in the distributed network
hash function in blockchain is the key to anti tampering, and hash algorithm is a one-way cryptographic mechanism to ensure that transaction information is not tampered in blockchain. After receiving a piece of plaintext, hash algorithm will transform it into a short and fixed hash data in an irreversible way. So block association has but is not limited to tamper proof
2. Quantum secure communication is divided into quantum cryptography communication, quantum teleportation and quantum dense coding. It can be divided into classical communication and quantum communication. The former mainly transmits quantum key, while the latter can be used for quantum teleportation and quantum entanglement distribution. When quantum communication is eavesdropped, although the eavesdropper can't get the information, the communication is interrupted, which affects the normal communication. His anti eavesdropping is at the cost of interrupting the communication, so it doesn't seem as good as the legend.. At present, there are still many unsolved problems in quantum communication, such as short transmission distance, relay difficulty and so on
3. In secure communication, technology competition and complementarity are mutual reference and common development. In secure communication, blockchain should belong to network layer, and quantum communication should belong to physical layer. Therefore, there should be no competition result of who will replace who.

5. It can only be said that before the advent of quantum computing, blockchain is safe, mainly because no one has seen how much computing power quantum computing brings

in fact, in the real world, even if quantum computing is implemented, if the topology of the whole network is still in accordance with the existing model (the infrastructure will be updated for many years), quantum computers can only greatly improve the computing power on a few nodes and obtain accounting rights, So basically, quantum computing should be safe before it reaches everyone's personal computer.

6. Recently, the water quantum community is really hot. In fact, the way to join them is very simple. Now they are also recruiting new partners, namely super node partners of the exchange. After becoming a partner, you can not only know the latest developments of the blockchain in time, but also be guided by the operation experts of the water quantum community team. You can also enjoy the rights of commission dividends, sponsors of digital assets on the exchange, dividends of currency fees, and so on.
