æternity is a public, open-source blockchain protocol that enables a platform for next-generation decentralized applications with high scalability. Its core components are written in the functional programming language Erlang and its smart contract language - Sophia - is also functional. æternity has a stellar team of developers including Robert Virding - co-creator of Erlang, John Hughes - co-designer of Haskell, and Ulf Norell - co-designer of the Agda programming language for formal verification. Unlike other blockchain platforms, the æternity protocol itself incorporates a number of essential technological features. State channels for off-chain scaling, oracles for real-world information, and a naming system for increased user-friendliness are all implemented on Layer 1. æternity also features SDKs in Javascript, GO, Phyton, Java, as well as a middleware and a development suite that streamline smart contract development. æternity incorporates the Bitcoin-NG consensus algorithm developed by academics from Cornell University and uses the Cuckoo Cycle mining algorithm for Sybil attack protection. AE tokens, the native cryptocurrency of the æternity platform, is used for both - an economic unit of account and as ballots in the community-driven on-chain governance votes.
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.
