Seal is a blockchain powered product authentication and services platform which will provide consumers and manufacturers with product trust. Seal enables anyone the ability to confidently, quickly and economically verify the authenticity of any product which is Seal enabled. Seal is the best way for anyone to check if a product is genuine or fake. Seal combines NFC chips, which are embedded into physical products, the Seal app, and the Seal Network to provide a fast, simple, and secure way to provide products authenticity and other services. By facilitating a secure tokenized version of a physical product, Seal allows product-specific services to operate such as transferring ownership, theft prevention, insurance, but also brand activation campaigns and product analytics. Seal lets brands earn money every time their products change owners. For the first time in history, brands can earn money from items sold through the secondhand trade, while simultaneously protecting their markets from counterfeiters. Using the power of the blockchain, authenticity can be checked and ownership can be transferred decades from now, even if the product itself is discontinued, as long as people contribute to the decentralized Seal network. Seal Network is designed for adoption by brands. Its business model allows brands to charge fees for services. For the first time in history, brands can earn money from items sold through the secondhand trade, while simultaneously protecting their markets from counterfeiters. Every time products change hands, the brand earns a fee, turning their products into revenue streams. This offsets the costs of equipping the products with NFC-chips while providing a lucrative revenue stream where brand monetizes their authenticity. By using the power of the blockchain, authenticity can be checked and ownership can be transferred decades from now, even if the product itself is discontinued, as long as people contribute to the decentralized Seal network.
Hcash is a new cryptocurrency designed to allow value transfer among blockchains and between blockchains and blockless cryptocurrencies. In addition, Hcash will support private transactions, DAO governance, and quantum resistance. Since Hcash hopes to be a side chain for many different cryptocurrencies, including privacy coins, it will need to implement privacy features to mask how users are moving their funds. To address this issue, Hcash will come with two types of wallets: white and black. While the white addresses will be publicly viewable, the black addresses will remain private. In order to achieve this privacy, Hcash will implement zero-knowledge proofs. This system, as proven on Zcash’s blockchain, involves masking the identity of the sender and receiver through the use of advanced cryptography to verify transactions without sharing information about the transaction with miners. As a result, blockchains that implement zero-knowledge proofs do not include any identifiable user information. Hshare offers enormous technical potential in the industrial, private network sector. Multi-compatible and multifunctional software, which is already designed for quantum processors, makes it possible to combine a wide variety of crypto technologies. This offers advantages in the FinTech area, in finance, in dealing with Big Data and also for the application area of the Internet of Things. Hshare seems to be not subject to any limitations.
