1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

2. One possible application scenario is: through transaction
to generate the corresponding behavior, assign the address
to each device, inject a certain fee into the address, and execute the relevant actions, so as to achieve the application of the Internet of things. Similar to: PM2.5 monitoring point data acquisition, server leasing, webcam
data call, DNS server, etc
in addition, with the increasing number of Internet of things devices and the increasing demand for edge computing, a large number of devices need to adopt a distributed self-organization management mode, and the requirement for fault tolerance is very high. The distributed and anti attack characteristics of blockchain can be well used in this scenario. Analysis of jinwowo network technology
