"The intent of Ethereum is to create an alternative protocol for building decentralized applications, providing a different set of tradeoffs that we believe will be very useful for a large class of decentralized applications, with particular emphasis on situations where rapid development time, security for small and rarely used applications, and the ability of different applications to very efficiently interact, are important. Ethereum does this by building what is essentially the ultimate abstract foundational layer: a blockchain with a built-in Turing-complete programming language, allowing anyone to write smart contracts and decentralized applications where they can create their own arbitrary rules for ownership, transaction formats and state transition functions. A bare-bones version of Namecoin can be written in two lines of code, and other protocols like currencies and reputation systems can be built in under twenty. Smart contracts, cryptographic "boxes" that contain value and only unlock it if certain conditions are met, can also be built on top of the platform, with vastly more power than that offered by Bitcoin scripting because of the added powers of Turing-completeness, value-awareness, blockchain-awareness and state."
What we don't like:
Ethereum has taken the crypto market to a new level. Sometimes being the first to mainstream adoption has its downside. New technologies such as NEO, ARK and IOTA, are trying to be the next Ethereum. They are offering faster transaction speeds and more blockchain features. Ethereum has to remain vigilant with updates to make sure it remains top dog.
What we like:
Ethereum has revolutionized cryptocurrency. Several of the of most valuable cryptocurrencies are on the Ethereum blockchain. It opened blockchain technologies to companies that don’t want to implement their own mining infrastructure. This has opened the floodgates for blockchain usage, while bringing cryptocurrency one step closer to mainstream adoption. With every successful company that comes out on the Ethereum blockchain, the value of Ethereum increases.
