Coin Review: I told a leader in charge of the digital economy that the new round of digital economy under the blockchain technology revolution is qualitatively different from the current digital economy. It is a huge change in the digital economy business paradigm. The current digital economy is essentially a traffic economy and an attention economy. It is an economy that monetizes traffic advertising and e-commerce sales. In the future digital economy, due to the blockchain confirmation and self-ownership of data and identity, traffic, attention, IP, data... can be "money" in themselves. The leader still didn't understand. He cited some examples of economic phenomena such as Bitcoin, Ethereum, Polkadot and meme, but still couldn't figure it out. He said: Anyway, the Internet is an information network, full of all kinds of information, and blockchain is a value network, full of all kinds of "money". He seemed to understand something. He added: What embarrasses governments now is how to regulate this "money", but this change is irreversible.
