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.
SpectreCoin (XSPEC) is an innovative privacy-focused cryptocurrency, featuring an energy-efficient proof-of-stake algorithm that provides rapid transaction confirmations, ring signatures for privacy and anonymity, and a fully integrated Tor+OBFS4 layer for IP obfuscation within the wallet. Spectrecoin is actively developed, with an ambitious roadmap that prioritises privacy, security, and true decentralisation with features such as default stealth addresses and stealth staking, and low-power mobile wallet staking in our upcoming Android wallet. Spectrecoin can be exchanged on several exchanges. The goal of Spectrecoin is to combine a blockchain with a tokenized ring-signature scheme to build a system of anonymous digital cash. The ring-signature scheme used here was first introduced by Shadowcat, and is now being improved on by the Spectrecoin developers. For network-level privacy, all nodes communicate exclusively within the Tor network via hidden services. The priorities of the Spectrecoin project are on privacy, technical soundness and simplicity. The Proof-of-Stake consensus method is used to provide environmental friendliness, decentralization and transaction speed. The project is built by a professional team and around the open participation of its community members, development is funded through an innovative staking-reward donation system and voluntary direct funding.
