I understand it should have been an architecture of software by using development concept, should be belongs to the category of technology,
See baidu encyclopedia: "narrow, chain block is a kind of according to the time sequence data blocks are connected by the order of the way, a chain of data structure and guarantee the tamper-resistant in cryptography and unforgeable distributed books, general speaking, block chain technology is to use the chain to verify the data structure and data storage, distributed node consensus algorithm is used to generate and update the data, using the way to ensure the security of data transmission and access of cryptography, intelligent use of automated script code contracts to programming and operating data of a new kind of distributed infrastructure and calculation way,"
I recently read a variety show, people from all walks of life such as tourism, dance training teachers are saying, oh, I also in research block chain I wonder if there are specialize in, you have your own career, could not have time to research software development technology, that is what they call a block chain and is not a thing we think of
