I am a serial entrepreneur in the IT domain.Originally I was a network engineer, and I have developed many services with various computer languages.I became involved in the crypto industry in 2014 when I try to launch a Bitcoin exchange.I have seen the development of the crypto industry and I am convinced that the wallet address will become the identity of the user on the internet and the wallet address will become DID in the future. Wallet addresses will be associated with a variety of data in addition to assets, and user's internet activity will be stored in it automatically to form a user profile.Referring to the history of the Internet up to now, various types of IDs have been linked to communication technologies.Email - email address, SMS - phone number, Chat and SNS etc.If wallet addresses will be IDs on the Internet, there will surely be technologies in the future that allow communication based on wallet addresses.DMTP project we are working on is first projects to put communication technology on the Web3 in preparation for that era.
