Haven is an untraceable cryptocurrency with a mix of standard market pricing and stable fiat value storage without an unsustainable peg or asset backing. It achieves this with a built in on-chain smart contract that controls the minting and burning of coins in a network of cryptographically unknown supply to facilitate value for users that choose to send their coins to offshore storage contracts while allowing everyone else to be exposed to the natural price movements of the currency. Offshore Storage Offshore Storage is Haven's built in smart contract/protocol that powers the stable value storage. In short, sending Haven to offshore storage (burning) records a reference on the blockchain to the current fiat value which can be restored later back into Haven by minting new coins to the tune of the current fiat value. The key use cases for offshore contracts are: Point of sales/payment gateway systems where goods can be bought with Haven and stores can immediately lock the fiat value in to protect from price fluctuations. This has the added benefit of keeping the stores business and income completely hidden on the blockchain as neither their wallet address or amounts are revealed. Storing large amount of money outside of the traditional banking system. Privacy focused cryptos are perfect for this but without a reliable way to maintain value through fluctuations the process of holding could be costly. Sending Haven offshore quite literally, makes money disappear until you want it back at which point the value remains intact. Untraceable | Hidden | Decentralized Haven uses ring signatures, ring confidential transactions and stealth addresses meaning payments cannot be tracked or linked back to any user. Wallet addresses and transaction amounts are completely obfuscated on the Haven blockchain making all activity invisible. The Haven Protocol is decentralized and open source meaning no central control over the network. Nothing is censored.
Sia is a decentralized cloud storage platform similar in concept to Dropbox and other centralized storage provider where instead of renting storage space from a centralized entity, clients rent storage space from other peers. The only difference is Sia uses blockchain to facilitate transactions Nodes provide storage to clients using the Sia blockchain as contracts. Before storing the data, the data is encrypted into many pieces and uploaded to different hosts. Siacoin is created by David Vorick and Luke Champine of Nebulous Inc. As the traditional storage platforms are higher in cost, more expensive and data is not well protected. Siacoin promises to offer secured storage transactions with smart contracts which is more affordable and reliable. Moreover, it is completely open source which means many individuals have contributed to Siacoin’s software hence there will be an active community building innovative applications on top if the Sia API. In 2018, Siacoin aims to introduce file sharing and be the go-to cloud storage platform for companies. Their goal is divided into 3 time frames which are short-term, medium-term and long-term development. Short-term development focuses on file sharing between Sia users. This allows Sia users to share files in the platform without having to take it off the cloud while increasing network utilization. Medium-term development’s goal is to enhance partnerships. This means reaching out to large companies like Netflix and Dropbox to hopefully be able to be their storage and distribution framework. Lastly, long-term development aims to expand its horizon to share files with non-Sia users and support mobile wallets.
