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.
Nuls (NULS) is a Singaporean based project is trying to develop a highly adaptable blockchain that can be used for enterprise solutions. They have regularly used the phrase “Nuls is nothing, Nuls is everything”. In other words, Nuls is not traditionally defined and can be melded into anything that the community sees fit. Nuls is looking to solve the problems faced by blockchains by creating one that features modularity and sub-chain operability. The two part design of functional modules and microkernels will provide both an underlying network mechanism and compartmentalized features for the blockchain.Essentially this should provide scalability and security to the blockchain, while adhering to the programming practices of low coupling and high cohesion. And because the blockchain is designed to be modular, it becomes hot pluggable, allowing for the addition or removal of modules at any time. There are several blockchain problems inhibiting growth and development of the industry that have been identified by the Nuls team. One such issue is the cost of development. Because there is a shortage of blockchain proficient developers, those with skills can command higher salaries.This is simply demand exceeding supply and will eventually level out as more IT professionals learn blockchain skills. That’s when businesses will see greater adoption of the technology, and only the most trustworthy blockchains will be of interest. Nuls is working to make trustworthy solutions to business problems. Nuls is primarily focused on making blockchain more accessible for developers and businesses. It seeks to do this through its modularity and the use of sub-chains, and hopes to break the complexity associated with blockchain projects, while also solving the scalability issue that is hindering the growth of the industry. Nuls will make trust simpler, increasing the adoption rate of blockchain technology by businesses. They will also lower the cost of entry by removing complexity and increasing the supply of developers capable of programming blockchain applications. Taken all together, the Nuls ecosystem will benefit developers, businesses, and cryptocurrency enthusiasts by providing needed solutions and increasing usage and adoption of blockchain technology.
