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.
ChainLink is a decentralized oracle service, the first of its kind. When Ethereum went live in 2015, it revolutionized what blockchain could bring to enterprise solution and traditional business. Blockchain was no longer just a medium for new age financial transaction, confined to Bitcoin’s potential to disrupt traditional currency exchange. With Ethereum powered smart contracts, Vitalik Buterin opened up a Pandora’s Box of use cases for blockchain technology. Problem is, per their design, smart contracts can only manage data on the blockchain. Their potential, the ability to provide tamperproof, decentralized applications for uses the world over, is still largely untapped, as many of the smart contract programs built on Ethereum lack a bridge to the real world industries they’re trying to improve. ChainLink’s first component consists of on-chain contracts deployed on Ethereum’s blockchain. These oracle contracts process the data requests of users looking to take advantage of the network’s oracle services. If a user or entity wants access to off-chain data, they submit a user contract (or requesting contract) to ChainLink’s network, and the blockchain processes these requests into their own contracts. These contracts are responsible for matching the requesting contract up with the appropriate oracles. The contracts include a reputation contract, an order-matching contract, and an aggregating contract. The first of these, the reputation contract, is exactly as it sounds: it checks an oracle provider’s track record to verify its integrity. In turn, the order-matching contract logs the user contract’s service level agreement on the network and collects bids from responsible oracle providers. Finally, the aggregating contract accumulates the collective data of the chosen oracles and balances them to find the most accurate result. Unfortunately, the ChainLink team does not offer a roadmap, but a testnet of ChainLink’s services should come sometime within Q1 of 2018. Generally, the project’s general lack of marketing and concrete updates have frustrated community members in the past. Sergey Nazarov, the project’s CEO, is known for a quiet community presence that favors of behind-the-scenes work on ChainLink. The team may not hype their project much, but for what it’s worth, they sacrifice brand marketing in favor of product development–and some community members find this focus to be refreshing. For instance, they’ve established an oracle with Swift Bank, and have a few quiet partnerships with zepplin_os and Request Network. Chainlink has the potential to connect smart contracts with the outside world. It may allow parties to smart contracts to be able to receive external inputs that prove performance and create payment outputs that end users want to receive, such as bank payments. This has the potential to allow smart contract to mimic the vast majority of financial agreements currently available in the market. With the ChainLink Network, anyone can securely provide smart contracts with access to key external data and any other API capabilities, in exchange for financial reward. Although it remains to be seen how the incentive system will operate, there is potential for rewards similar to those available for crypto miners to be available to Node Operators that provide useful data to the Chainlink network.'
