LangChain will create a fair ecosystem for the translation industry through Block Chain and AI. And based on this, it will create a smaller world without language barriers..AI technology companies have diminished the faith in the industry by unfairly obtaining translation data. LangChain will create a transparent and fair trade structure through the Token and Point system. .LangChain keeps a transparent record of translation industry's goods trading (Token) on EOS, creation and utilization of data based on Points, and activities of LangChain application.Now, linguists can use LangChain to receive fair reward, enjoy their work more, and even contribute to the advancement of AI translation technology..Currently, we are developing the initial "services" and "tools" for the implementation of LangChain.One of the services is supplying the demands of the existing translation market and the new translation market for Block Chain services such as Steemit and Everipedia. Another is the Cloud CAT that enables the linguists to work easier and use LangChain more conveniently..The translation industry is a market divided by borders. LangChain's "Token" will be used as a means of goods trading for translation services. This can unify the translation markets dispersed to various countries and the new AI/Block Chain translation market into one..The translation industry will come to accept the innovations of AI technology for the first time through LangChain. The competitiveness of the innovated translation industry will make all translation industries embrace LangChain.
