August 15

Feng Han participated in the 2020 International Digital Economy Ecological Summit held in Ganzhou. Feng spoke on how blockchain will bring wealth to our country and people, and the free market is actually a distributed computing system that is comparable to the “Turing machine”.  The privatization of data makes data become wealth, and China’s digital economy will usher in a new digital wealth.


August 17

The DeFi Digital Financial Breakthrough online forum co-sponsored by Block Finance, JRR Crypto, and HALO officially launched. Feng Han attended the online forum where he said, “The current popularity of DeFi is an inevitable stage of the development of blockchain wealth consensus. DeFi will become the ignition point for this year’s market. The financial market will not be created without liquidity. A broad financial consensus is needed to realize the digital economy.”


August 22

Rong Chen and Feng Han were invited to participate in the Elastos third anniversary online celebration held by the Chinese community.

Rong Chen: Elastos is doing the Tier Two network, and Crypto projects such as ETH World Computer, Web3.0 (Polkadot), DeFi and IPFS are Tier One. Tier One cannot be directly used by consumers. What Elastos is doing is a P2P smart Internet that ordinary people can use to communicate with each other

Feng Han: We have seen signs of a bull market. It is more and more obvious that DeFi and decentralized storage will become the business opportunity for the next bull market. All of these projects are moving toward the same mission of Data Capitalization.
