GSC (Global Social Chain) is the world's first new generation of social networking chain that owns hundreds of millions of social users. This social chain is determined to use block chain technology to subvert centralized social networks such as Facebook, WeChat, etc., which plays a dual role as 'manager' and 'arbiter' simultaneously for the former social networking platforms. Social network is the most important basic measure of the Internet. It conveys the user's daily high frequency interactive behavior. However, at present, all the centralized social networking platforms, such as Facebook, Snapchat, etc., are facing many pain points. The security of users' private information cant be guaranteed; The user data can be used by the platform at any time; There is a lack of incentive as the values created within the content of the user belong, at last, to the platform; Credit system vulnerability, false information, and low social efficiency. The social network is a natural source applied to the centralized block chain technology. GSC's vision is to utilize the block chain technology to restructure the values of the next generation of social networking platforms and let the security of the private data and the digital assets become individual. Through the in-depth cooperation with the famous social networking application Mico, we have the chance to validate the solution of the block chain technology on the product matrix of Mico and made very effective progress.
Beam Mimblewimble is a scalable, fungible, and confidential cryptocurrency based on the Mimblewimble implementation. WHY BEAM? Core features include complete control over your privacy, All transactions are private by default, No addresses or other private information are stored on the blockchain, Superior scalability due to compact blockchain size, Opt-in Auditability, Support online and offline transactions, atomic swap, hardware wallets integration. Governance model No premine, No ICO. Backed by Treasury Establishing a non-profit foundation to govern the protocol after Mainnet launch How does it work? Wallets’ owners create new transaction using secure channel either online or offline Both wallets participate in signing the transaction using Schnorr protocol Wallet sends transaction to node Each transaction contains a list of Inputs and Outputs represented by Pedersen Commitments, as well as explicit fees and kernels. Each transaction also contains non-interactive zero knowledge range proof to verify that the output transaction value is positive Transaction is verified by the node Each transaction is verified with respect to the recent blockchain state which is stored as a Merkle Tree. The root hash of the tree is recorded in block header along with a proof of work. In addition, each node periodically creates compacted history to allow ‘fast sync’ of new and existing nodes. Transaction is added to the mining pool A block is mined every minute and is sent back to the node for verification and distribution. Mined blocks containing the new transactions are sent to the known peers A valid block that is extending the longest chain is accepted as a new Tip and propagated further until full consensus is reached. Fast sync When a new node connects to the network for the first time it can request compacted history containing only system state and blockchain headers. There is no need to retrieve the entire transaction history.
