SDChain-Iot &Taiwan Internet of Things Association Deliver a Joint Lecture
Chen Yuhua, founder of Green Springs and GBC issuer, which has adopted SDChain-Iot blockchain technology, was invited to the event to explain how they had utilized blockchain to develop the planting and promotion of camphor trees. The Green Springs approach to solving environmental problems is to plant trees. It calculates the value of tree ecology through the combination of the Internet of Things and blockchain technology. According to the ratio converted by the National Forest Administration of the United States, the ecological value of trees is nine times the economic value of the market. All investors, producers and consumers can clearly see the credible data recorded through the combination of the Internet of Things and blockchain technology. As a result, they can contribute to the environment and ecology while earning GBC. That means they can generate profits while contributing to public welfare. In the future, Green Springs is also expected to introduce a cloud-based large data intelligent decision-making system to quantify the economic value and ecological value of the growing trees, make tree planting profitable, expand market capital participation and promote social value investment.
SDAT Decentralized Exchange Interview with DIGITIMES
It is mentioned in the interview that on the one hand, enterprises can directly issue their own tokens in the innovative and unique DIYO (Do-It-Yourself-Offering) model as expected, and thus they can widen their trading channels by sharing trading depths in SDChain-supported decentralized exchanges such as the SDAT decentralized exchange and exchanges belonging to other SDAT Institutional Investor Alliance members. On the other hand, the SDAT Institutional Investor Alliance members who are very experienced in the investment industry, can utilize SDAT membership tokens, to access the rights and the interests of members at private fund-raising roadshows to perform due diligence on projects, and help support high-quality capital investment projects.
In terms of the application of SDAT tokens, each member, according to the number of SDAT tokens they hold, is ranked at different levels. Each member can enjoy their entitled due diligence time period according to their SDAT tokens held. During this period, members can participate in online roadshows, listen to the project pitches, and ask questions in a timely manner to decide whether or not to invest.
Development progress
SDChain-Matrix
1. Completed the main process development of the token authorization cancellation function for TokenApproveCancel of the NFT heterogeneous assets in the SDChain-Matrix ERC721 standard to realize the cancellation of the transfer of the right of use by the issuer. The transaction type of TokenApproveCancel is ttTOKEN_APPROVE_CANCEL, which checks the validity of the target address, checks the permission, sdApproved, and updates the Token information in the pre-check stage.
2. Completed the main process development of the asset authorization function for AssetApprove of the NFT heterogeneous assets in the SDChain-Matrix ERC721 standard to realize the transfer of all Token usage rights in the asset by the issuer. The transaction type of AssetApprove is ttASSET_APPROVE which checks the validity of the signature and calculates the authorized authKey in the pre-check stage.
