SDChain asset mapping has started
The main network asset mapping work on the wallet channel started at 06:06:06 on August 26, 2018. Due to the uncoordinated development time of the interface of the mapping work for each exchange channel, the official release for each exchange is subject to the information in the recent press release.
During the mapping of the main network assets, the e-SDA completed through the wallet channel will be destroyed and announced by the SDChain Alliance. The s-SDA held by users can be traded on an exchange that has completed the mapping work or they can be applied to the development of the community.
Before the cooperative exchange initiates asset mapping, e-SDA can continue to trade on the exchange, but the transaction will be suspended during the mapping work. After the exchange mapping work is completed, the original e-SDA will be destroyed and publicized. s-SDA will continue to trade on the exchange.
Hangout of SDChain Taiwan Business Application
Hangout of SDChain Taiwan Business Application, a meeting targeting companies and cooperative agents who want to quickly introduce blockchain, began on August 31, with representatives from several industries participating in the event.
The six-domain chain Co-Chain technology is an innovative blockchain cooperative symbiosis technology proposed by the SDChain core development team. Based on the SDChain low-level blockchain construction, an underlying platform of the blockchain with equivalent functions can be quickly established. The technical advantages of this are: fast Token Insurance, fast blockchain deployment, 5000 TPS high efficiency (vs 15 TPS on Ethereum), and low gas costs.
Dr. Jie Shen was elected as the rotating team leader of the Blockchain Reform Working Group of the Shanghai Blockchain Technology Application Association
Dr. Jie Shen, the chief scientist of SDChain, attended the first technical committee meeting of the Shanghai Blockchain Technology Application Association and was elected as the first rotating team leader of the chain reform working group.
During the conference, leaders of the association, representatives of Shanghai’s excellent blockchain enterprises, media and investment companies, etc., discussed the reform of the blockchain — specifically chain reform — hoping to promote the integration and development of blockchain technology, models and industries. Reforming the blockchain will contribute to the transformation of the real and the digital economies, promote the transformation of new and old kinetic energy, reshape the blockchain industry structure, and promote industry consensus and healthy development.
Q & A: SDChain main network asset mapping of the wallet
SDChain Alliance announces official launch of main-network asset mapping.
The mapping work is divided into two parts. The mapping work of the exchange part is implemented by the SDChain Alliance and the exchange; the mapping of the wallet part requires the user to participate in the mapping and manually operate it.
Some SDChain users have encountered problems in the manual operation of the wallet mapping. The SDChain officially listed some common problems encountered in the mapping of the wallet and answered them one by one.

SDChain blockchain assists in the recruitment of “Beyond Silence” actors
In order to encourage the public to support public welfare projects and accelerate the collection of filming funds through the SDChain blockchain developed by SDChain Alliance, “Beyond Silence” will cooperate with SDChain before the film starts, while it is being shot, after the film is released, and during the event promotion period. The public welfare exclusive fan publicity activities include artist fan clubs, studio visits, title sponsorship, and in-the-can cocktails as well as premiere and pre-sale movie tickets.
In addition, SDChain Alliance also assumed the election work of overseas actors: “Beyond Silence” opened six roles in Canada for recruitment (3 men and 3 women). See https://mp.weixin.qq.com/s/hKuAG8DPLz_V8nzMwQKY0w for details.
