Shadow (SDC) is a peer-to-peer privacy platform, created under an open source license, featuring a built-in , end-to-end encrypted messaging and E-commerce. The decentralized network aims to provide anonymity and privacy for everyone through a simple user-friendly interface by taking care of all the advanced cryptography in the background. ShadowCash was created as the de facto currency for the peer-to-peer decentralized ShadowMarket (currently under development). The project began in July 2014 as a fork of Bitcoin (BTC) engineered to enhance the bitcoin protocol by adding dual-key stealth addresses and traceable ring signatures for increased transactional anonymity.
ShadowCash consensus is based on an open source protocol known as Proof-of-stake (PoSv3) and is not managed by any central authority, the network regulates itself.
The main component of the Shadow platform is the decentralized marketplace dubbed 'ShadowMarket'. The decentralized nature of the network makes it very resilient against shutdown attempts and permits for anyone to participate in a true free market without the possibility of interference or eavesdropping by malicious parties. Every node in the network distributes and stores all the open market listings, to prevent bloating the network with outdated and incorrect listings, each one must contain an expiration date and the appropriate listing fee must be paid. The blockchain-like mechanism for storing the listings is a technique called Private Information Retrieval and is key to preserving the anonymity and privacy of both the vendor and possible buyer(s).
The smart escrow system is devised so neither party can profitably defraud the other party without risk. It is based on mutual assured destruction (MAD): The buyer risks twice the amount required for purchase and the vendor risks the purchase price plus the item that they ship. These funds are locked in a 2-of-2 multisignature address and can only be released when both parties agree and sign the transaction. If they can't agree before a certain expiration date, the funds stay locked indefinitely and the address becomes unspendable. The expiration date is extendable if both parties agree to send the transaction to yet another 2-of-2 multisignature address with a new expiration date.
