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.
Stratis is a powerful and flexible Blockchain Development Platform designed for the needs of the real world financial services businesses and other organisations that want to develop, test and deploy apps on the blockchain. Stratis significantly simplifies the development process for creating Blockchain applications and accelerates the lifecycle for Blockchain development projects. Stratis private chain allows businesses to deploy their own customise blockchain without the costs of running their own blockchain network infrastructure. The vision of the Stratis platform is to become a one-stop shop for all blockchain things, mostly becoming a blockchain-as-a-service (BAAS) platform. Technology-wise, it is a clone of Bitcoin’s core code, with a few enhanced features and written in C# language instead of C++. The team is based in the United Kingdom but has a decentralized structure with members spreading across the world. Several people on their management team are well-versed in enterprise software development using .NET and C# – a positive sign considering those are the project’s two primary languages. Chris Trew, the founder and CEO, has over 10 years of experience in enterprise IT and was a volunteer developer for the Blitz project. Stratis is competing against other BaaS projects in an increasingly saturated but gigantic space. Lisk may be the largest direct competitor in offering sidechains for businesses. However, Lisk is written in Javascript (not C#) and has sidechains that are more publicly available. The decreased privacy may be a turnoff to corporations looking to keep their code proprietary. The company held an ICO in June 2016 and manage to raised 915 Bitcoin.
