The road to exile Mining is all the way down
bitcoin is no longer easy to dig, and it is much cheaper than before
maybe you can only dig for a few hours a day and lose money
even if you mine with a high configuration computer in your own home, it is estimated that you will consume a little more electricity, not counting the aging depreciation of the computer.
at present, Ethereum blockchain has exposed three major problems, and its founder vitalik
buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied
20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.
On September 2, it was reported that on August 21, the central bank headquarters received the relevant emergency report. The report analyzed in detail and clearly pointed out that from the perspective of penetrating supervision with substance more important than form, ICO belongs to illegal fund-raising in disguise
according to the lover quoted, relevant people of the central bank have studied a large number of ICO white papers and come to the conclusion that "90% of ICO projects are suspected of illegal fund-raising and subjective and intentional fraud, and less than 1% of the ICOS that actually raise funds for project investment."
what is the development history of ICO
July 2013: mastercoin (now renamed mastercoin Omni) is one of the first blockchain projects to carry out ICO. It successfully raised 5000 BTC in bitcointalk forum. Mastercoin is a second-generation token based on bitcoin protocol, which aims to help users create and trade cryptocurrency and other types of smart contracts
March 2015: Factom innovates the data management and data recording methods of commercial society and government departments by using bitcoin's blockchain technology through konify platform ICO
March 2016: lisk's decentralized application (dapps) uses JavaScript language for programming, which is the simplest and most popular programming language in the world. Lisk raised a total of 14080btc and more than 80 million XCR this time. The amount of crowdfunding ranked second in the ICO of blockchain project, second only to Ethereum
may 2016: the Dao is the largest crowdfunding project in the history of ICO, with a financing amount of US $160 million. The full name of Dao is decentralized autonomous organization, which can be understood as a company like entity completely controlled by computer code. It is the first time in human history. But ICO project, which attracted a lot of attention, was attacked by hackers, and then split between hard and soft in the debate, and finally ended up with disbanding and returning Ethernet money
September 2016: firstblood combines the electronic competition service with the blockchain, and uses the smart contract to solve the problem of reward structure. Crowdfunding raised US $6 million at the beginning, with a total of 465312.999eth in the world
01. Student status
the entry system constructed by the top-level application requires human operation, that is, information entry. Each entry terminal is equivalent to each node. The confirmation of entry needs to be verified on the blockchain, and the time stamp proof mechanism will also be added
ensure that each student status information can not be tampered with. Everyone's all information is stored in each node, can't cause the loss of information because of any data damage or loss. Each corresponding person has a complete information system on the blockchain to ensure that all data coexist on the basis of one chain. On this basis, at any time, the location can be queried to identify the authenticity
02. Ecational resources
the problem of ecational resources can be stored in the blockchain structure. Each as a node structure, teachers can publish their own related teaching application courseware, multimedia courses on it, distributed in multiple nodes at the same time, which can ensure information sharing and data query
each message has an independent time stamp verification, which ensures that the rights and interests of the publisher are not infringed. Original teachers can not only enjoy rich ecational resources to carry out relevant teaching work, but also publish their own original works to obtain corresponding popularity and income
03. Academic problems
just imagine if blockchain technology is used to record each implementation process and step, and the release time can eliminate this problem. Any process, the time of each process and the time of the final result are stored on the blockchain. Anonymity, non tamperable encryption can guarantee the authenticity of the published information, which is not controlled by anyone
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It 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 common high cost, low 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.
