Yilian blockchain rental platform

1. We can only talk about domestic examples. High quality application platforms such as the blockchain rental platform in xiong'an New District of Hebei, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan are the first to lead into the era of blockchain 3.0.

2.

The three characteristics of blockchain are well known, that is, decentralization, transparency and non tampering. The tamper proof feature makes blockchain used in many places. Such as proct traceability, privacy protection and so on

because the proction process it traces back to is artificially uploaded, so even if it is tamperable data, the authenticity of the data can not be guaranteed, and the substantive problem still can not be solved

generally speaking, although blockchain has brought great benefits, it is not perfect after all. However, blockchain technology has promoted the development of the times, and I believe its future is worth looking forward to

3. In the blockchain system, it is necessary to describe the ownership, protect the ownership, store the transaction data, distribute the ledger to an untrusted environment, add transaction records to the ledger, and decide which ledger determines the truth
bitcoin is a typical blockchain system, which can be studied carefully

4. Australia, Japan and Canada are all developing well. For example, in Japan, even the government has begun to apply the blockchain technology. Some of their government affairs, such as government bidding, are completed on the blockchain platform. There are also high-quality blockchain government affairs platforms in China, such as the blockchain rental platform in xiong'an New District of Hebei Province, the blockchain government affairs platform in Chongqing, and the SMIC blockchain public service platform in Changsha of Hunan Province. They have done well and achieved good results.

5. One part of a $290 million contract between big blue and IBM is to build two of the world's fastest computers for the U.S. Department of energy. At the 2002 supercomputer technology exhibition in Baltimore, IBM will jointly announce the plan with the National Defense University, an official of the Department of energy< According to the terms of the contract, IBM will manufacture two supercomputers for the Department of energy, and their combined computing capacity will exceed the total of the world's 500 most powerful supercomputers
the first supercomputer to be provided by IBM is called ASCI purple, and its computing speed will reach 100 trillion times per second, that is, the level of teraflops. The computer is considered a direct descendant of deep blue. Dark blue was made by IBM in 1997 and was used to play chess with Garry Kasparov, then the world champion of chess
the second supercomputer is currently named blue gene / L, and its computing power will significantly exceed ASCI purpose, reaching 360 trillion times per second. It is expected to be delivered in 2005. The Department of energy plans to use the computer for national laboratories such as Los Alamos, Sandia and Lawrence Livermore to simulate weapons, biotechnology and high-energy explosions.

6. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. It can be combined with any traditional instry to proce innovation
for the blockchain rental instry, let's take the living planet as an example. The whole operation process of habitation planet is based on the blockchain smart contract. The contract is jointly formulated by multiple users in the blockchain. Once the coding is completed, the smart contract will be uploaded to the blockchain network, that is, the whole network verification node will receive the rental contract from the landlord and tenant. At the same time, the resident planet will regularly check whether there are related events and trigger conditions, and the events meeting the conditions will be pushed to the queue to be verified. Assuming that you have paid the rent, this event will become the trigger condition of the contract. Your personal data will be directly transferred by the chain, so that you can directly check in without meeting with the landlord, eliminating the tedious communication link; When you do not renew the contract, the smart contract will be executed automatically.

7. Dag is also a directed acyclic graph, in which there is no concept of block. The whole flow chart is composed of one transaction. The advantage is that it can save the block and packing process. The advantage is faster, no transaction costs, and no mining
iota adopts DAG technology to build a residential planet of blockchain rental platform, and will also be developed on the basis of iota. Ideally, the larger the network, the faster the transaction confirmation speed of iota, and the more secure the network. The purpose of living planet is to realize the interconnection of intelligent terminals such as intelligent door lock, router, camera and so on.
