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.
Spendcoin is a decentralized cryptocurrency that powers the Spend.com ecosystem of products. Spend has two financial services products, the Spend App and Spend Card, which are products of Spend.com that give our users a multi-currency digital wallet that they are able to store fiat and digital assets/currencies. They will be able to buy, sell, store, manage, and exchange all supported currencies within the app. The Spend App is available on iOS, Android, or Web based devices. The Spend prepaid debit card allows users to send fiat based currencies loaded onto it via the Spend App anywhere that accepts MasterCard. Spend Foundation is also launching a decentralized educational platform called Blockchain University (bu.org). Blockchain University is designed to run off our open-source blockchain called Cross Ledger which incorporates a hybrid delegated proof-of-stake consensus model called Proof-of-Support. Proof-of-Support creates a learning based ecosystem that rewards those users who support and answer the knowledge base and Quora style system. Spendcoin will be the native digital currency powering the platform. Blockchain University and Cross Ledger are planned to launch in 2019.
