1. Business Cards

When you check your business card, a message appears in the blockchain information section: Authenticated users are visible to others.

When you check the others business card ( unauthenticated user ), we blur the amount, which indicates that unauthenticated users are not visible to others.

We have added a new display of rankings ( the whole network rankings )

We have added the unregistered user who can send “do”. If there is no response ( background record, pending ), then we will remove the invitation.

We have added a new certification list.

When you are interacting with the user, we added a prompt for “do”.

CCHN Newsletter

Attending the 2018 Global Blockchain Developer Conference

On December 15, 2018, the 2018 Global Blockchain Developer Conference was successfully held at Crowne Plaza Hong Kong Kowloon East. Michael Yeung, chief scientist of CelesOS, attended the conference at the invitation of the conference organizers. In addition, experts from the industry such as Bitmain Corporate founder Wu Jihan, Bitcoin.com founder Roger and BitcoinABC chief developer Amaury also appeared at the meeting and shared their latest experience.

The 2018 Global Blockchain Developer Conference ( GBDC ) is jointly sponsored by Satoshi Foundation and Bitkan. Its purpose is to strengthen the exchange and cooperation of blockchain technologies, improve the construction of various developer communities and inject more strength into the blockchain industry.

The meeting brought together the world’s top developer team in the blockchain industry, high-quality project parties, professional media, more than 10 digital cash exchanges and wallets, well-known investment institutions in the blockchain field, leading enterprises in the blockchain application industry, and representatives of the blockchain derivative industry.

The meeting discussed the development trend of blockchain, blockchain finance, privacy security, smart contracts, DPoW, DAPP and other topics.

Michael Yeung, chief scientist of CelesOS, said in his share with the participants that DPoW is the consensus algorithm we invented and used in CelesOS. DPoW means Delegated Proof of Work, which is similar to DPoS, but the ticket source does not come from token but from hash. The answer to the puzzle of miners’ POW calculation is a one-time ticket, which can be accumulated and then sent to the block producer ( BP ).

Through this conference, CelesOS has been recognized and welcomed by more people in the industry. CelesOS will continue to develop the financial service capability of the blockchain, improve the ecological blueprint of the blockchain industry and promote the vigorous development of the blockchain technology.

CelesOS is a new generation of blockchain operating system, integrating the latest blockchain technologies such as cross-chain technology, DPoW consensus mechanism and legal compliance framework, aiming to increase mutual trust between institutions, reduce compliance costs and improve efficiency.

CelesOS team members are all from top universities such as Tsinghua University, Peking University, UC Berkeley, Massachusetts Institute of Technology and Virginia Tech. Before joining CelesOS, they worked for the National Development Bank, CICC, Tencent and Huawei.

The team is very familiar with and proficient in the financial industry and financial supervision, and forms a gold team combining finance, supervision and blockchain technology.

Celes would like to thank every follower for your support and love for Celes. Welcome to follow us and we will continue to broadcast more informative news about Celes. Let us witness the reform of the blockchain together.
