VeChain is a blockchain-enabled platform that is designed to enhance supply chain management processes. By utilizing tamper-proof and distributed ledger technology, VeChain provides retailers and consumers with the ability to determine the quality and authenticity of products that are bought. From product source materials, to servicing history, and spare part replacements, every single piece of information about the supply chain movement of a product can be recorded and verified to bring about a supply chain management ecosystem that is secure for all participants. VeChain plans to achieve this secure supply chain management ecosystem via the method of asset digitization. VeChain enables manufactures to assign products with unique identities to the platform. This will allow manufacturers, supply chain partners, and even consumers, to track the movement of products through their supply chain. There is also the VeChain Foundation. The Vechain Foundation is a non - profit entity established in Singapore in July 2017 and is responsible for the construction of the network, and technological research and development. The Foundation also plays an important role in business development. The Foundation encourages and supports partnerships with enterprises that may be interested in utilizing blockchain technology as a service. This includes payment services, private key management, smart contract development, and wallet development. There is no doubt that blockchain technology can be an important innovation to supply chain management. With a growing list of business partnerships and technological developments, VeChain is positioning itself to be THE disruptive, and innovative force that reshapes the way we think about supply chain management. The solution of 'hard forking' has made people question the idea of 'de-centering' of Ethereum and even Blockchain. This way of governance is not so much a 'democracy' as an 'anarchy.' VeChain development team highly regards blockchain’s decentralizing nature, yet intends to adopt some traditional corporate governance and thus improve the efficient formulation and implementation of the VeChain development and strategy for the benefit of the community to prevent and avoid serious blockchain design philosophy differences and irreconcilability. Sunny Lu is the CEO of the VeChain Foundation and has already become an important figure in the blockchain space. Before he established VeChain, he co-founded the Chinese Internet start-up which developed Qtum, a very important digital asset in the crypto space. He was previously the CIO and COO of Louis Vuitton China.The team behind VeChain consists of over 90+ employees, most of them being developers. Chief Technology Officer, Gu Jianliang, has over 18 years of experience in areas such as mobile devices and the IoT field, and has created over a 100 patents in several technological fields. Kevin Feng serves as the Chief Operations Officer of the VeChain Foundation. Feng has been actively involved in many technology projects in his 12 years working for VeChain’s partner, PWC, as a consultant and assurance advisor.
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.
