The hottest things this year are "bitcoin", "Ethereum" and all kinds of cryptocurrencies, so hot that even aunts and uncles are about to start talking about them. It is no exaggeration to say that 2017 is the first year of the development of cryptocurrency and blockchain technology

as the underlying technology behind bitcoin, the concept of blockchain has only been mentioned in the past two or three years, although as early as 2009, "Nakamoto Tsung" released bitcoin. After this wave of digital currency boom, the concept of blockchain technology has really entered the eyes of all walks of life. I'm afraid it's too early to mention the wide application of blockchain technology, which is still in a very early stage of development. However, e to the arrival of the boom, many technicians and teams have contributed their efforts to build some blockchain concept projects“ Needless to say, as the first application of blockchain technology, bitcoin of "Zhongben cong" has realized the function of distributed ledger, which can realize the first decentralized value transmission of human beings. It can be said that it is "blockchain 1.0". Then Ethereum invented the smart contract, which extended the function of blockchain technology to build applications. It is well deserved to be defined as "blockchain 2.0". However, the blockchain concept projects that came out later did not realize this leap forward role, but only improved to a certain extent at the application level, so they can not be called "blockchain 3.0"

so what is "blockchain 3.0"? Maybe bitcoin OS is the answer: an operation system that is completely based on blockchain technology and follows the concept of blockchain technology. In the 1980s, before Microsoft released the windows operating system, personal computers and Internet technology were still in a non systematic state and could not be popularized. After the release, personal computers were allowed to enter ordinary people's homes, making PC and Internet universal application procts. Recently, bitcoin OS team announced the implementation of the bifurcations of bitcoin and Ethereum on Christmas day, so as to officially publish the plan of developing blockchain OS

anyone who knows a little bit about blockchain technology knows that bitcoin solves the problem of account book, while Ethereum is a smart contract to realize application expansion. Later, a team will launch a distributed storage project. But these systems with only a single functional mole are not "operating systems". The traditional definition of operating system is a huge management and control program, which includes five management functions: process and processor management, job management, storage management, device management and file management. In fact, the OS based on blockchain does not need to change all the five functional blocks into distributed ones, as long as the parts related to the external transmission of value and information can be decentralized and distributed. Therefore, the blockchain operating system should have at least three functions of "account system management, computing resource management and storage resource management", which can realize distributed ledger, edge computing and edge storage. Although it is still too early to define the instry standard in this way, bitcoin OS team is committed to realizing the blockchain OS possessed by these three functional blocks first, and then improving it through iteration

according to the bitcoin OS team, the name "bitcoin OS" is actually "blockchain OS", which is named after "bitcoin", which is also a tribute to the inventor "Satoshi Nakamoto". At present, from the technical details given by the bitcoin OS team, we may be able to see some aspects of this "blockchain 3.0" project

firstly, the management function of the account book system supports locating the ownership of resources according to the account ID, such as the private key; Computing resource management can obtain corresponding computing resources according to the demand, support edge computing, and share distributed computing power. In addition, storage resource management can use storage resources according to the demand, and support edge storage. Compared with bitcoin OS, Ethereum only supports account system and smart contract, which can not meet the distribution of distributed computing tasks. Ethereum only supports the fair execution of contract code, let alone the management of storage resources. So Ethereum is only a custom calculator

in addition, it is worth mentioning that bitcoin OS self customized enhanced smart contract. It supports two modes, which are more flexible and efficient

1. Central computing mode: the outgoing node is responsible for executing the smart contract, and both the incoming parameters and the output results support sipfs to be stored in the storage node

Distributed computing mode: ordinary nodes can claim computing tasks, input parameters and output results support sipfs storage to storage nodes

finally, we also need to mention the built-in sipfs super interstellar file system of bitcoin OS. Sipfs can realize the decentralized storage of technical input parameters and output parameters. At the same time, the file has a life cycle, and the DNA description of the file descriptor is recorded on the blockchain. The file descriptor of sipfs does not exist on the blockchain, but it will be stored in a separate file descriptor data file. After the end of the file life cycle, the blockchain will automatically delete the file descriptor, Realize the intelligent slimming of blockchain

"blockchain 3.0" is worth looking forward to, and bitcoin OS team, as the vanguard, is worth paying attention to and encouraging. We are looking forward to the real blockchain operating system

4. Blockchain is a term in the field of information technology. In essence, it is a shared database. The data or information stored in it is characterized by "unforgeability", "trace in the whole process", "traceability", "openness and transparency" and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects

5. It is said that the homework of primary school students is worth 100W, and you bought it for 100W. If you sell it, you may earn money, but if you don't sell it, it's rubbish

6. In the traditional case, no matter the size of the system behind a database, the database is like a large ledger. For example, the database of a certain treasure is like a big account book, which records how much money a user has and how much money b user has. If a user pays one yuan to B user, a treasure will add one yuan to B user's account and subtract one yuan from a user's account. Therefore, the change of database can also be regarded as an accounting behavior

we usually think that the one who maintains the system is the one who manages the database, and other users have no right to participate. Just like the users of a certain treasure can not participate in the specific bookkeeping behavior

but blockchain subverts the tradition and lets every user in the system participate in it

blockchain is like a large total account book. Every user in the system can participate in competitive bookkeeping. In a certain period of time, the system will find the fastest and best users among competitors. The user writes the data changes in this period to a block, just like writing to an account page, and copies this account page to all other users in the system for backup, completing the whole action. In the next period of time, every node in the system has a of the complete ledger

since each block data is linked together through cryptography technology, we call it "blockchain" or "distributed ledger technology"

blockchain, let the whole people participate in bookkeeping. Because there is no specific bookkeeper in the system, any part of the nodes in the system will not affect the operation of the system if they are lost or destroyed. It is safer for all people to keep accounts. The system stipulates that the same number of accounts with the largest number are true accounts, and a small number of accounts that are inconsistent with other users are false accounts. This makes it difficult for a blockchain with enough nodes to be attacked and tampered with. These nodes are distributed in any corner of the Internet. Unless you are God and can control most computers in the world, you cannot tamper with them. Therefore, blockchain is considered to be the most secure way of data management in history. National bookkeeping is more efficient. Because there is no centralized intermediary organization, it can run automatically through pre-set proceres, which can greatly rece costs and improve efficiency, and ensure that the process and content of account records are open and transparent

bitcoin is only an experimental application of blockchain technology in the field of payment. Blockchain can also be used in a broader field, including medical treatment, supply chain, Internet of things, security authentication, social networking and artificial intelligence The economist called blockchain "the trust machine" and believed that it would have a huge and far-reaching impact on global finance and even social structure

to sum up in one sentence, blockchain technology is a way that enables all participants in the system to work together to record and maintain a reliable data log under the environment of multi-party without mutual trust through cryptography technology

bitcoin, blockchain content publishing platform decent and lightcoin all use blockchain technology, and anyone can participate in it in theory.
