Ethereum is a smart contract platform that enables developers to build tokens and decentralized applications (dapps). ETH is the native currency for the Ethereum platform and also works as the transaction fees to miners on the Ethereum network. Ethereum is the pioneer for blockchain based smart contracts. Smart contract is essentially a computer code that runs exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference. It can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Ethereum allows programmers to run complete-turing smart contracts that is capable of any customizations. Rather than giving a set of limited operations, Ethereum allows developers to have complete control over customization of their smart contract, giving developers the power to build unique and innovative applications. Ethereum being the first blockchain based smart contract platform, they have gained much popularity, resulting in new competitors fighting for market share. The competitors includes: Ethereum Classic which is the oldchain of Ethereum, Qtum, EOS, Neo, Icon, Tron and Cardano. Ethereum wallets are fairly simple to set up with multiple popular choices such as myetherwallet, metamask, and Trezor.

Aion is a revolutionary multi-tier blockchain platform that has been created to solve the pressing issue of limited operability between existing blockchains while still remaining capable of handling its own applications. It supports custom blockchain architectures, and it provides cross-chain interoperability. The Aion project comes at a very appropriate period, in a time where there’s an ever-growing number of blockchains.Thus, interoperability is more important now that it ever has been. Interoperability will expand the horizons of multiple other blockchain platforms, not to mention those of enterprise-oriented companies. The project is led by Matthew Spoke, the CEO of Nuco and board member on the EEA. Other big names include Jin Tu, Nuco’s CTO, who has more than 15 years of experience in enterprise engineering and more than four years in the blockchain industry, and Peter Vessenes who has co-founded the Bitcoin Foundation. The token is the blockchain’s power-source. It’s used for securing the network, for creating new blockchains, as well as for monetizing inter-chain bridges. AION token is actually an ERC-20 token. In fact, the token is first offered as an ERC-20 token on the Ethereum blockchain, and only then it can be changed to the official AION network token. When that happens, the token can freely stream between two blockchains. The best thing about this is that investors are not required to change their Aion Ethereum token (ERC-20) for the Aion-1 token, as they will always be interchangeable. In order to buy AION, you will need to first purchase another cryptocurrency, preferably Bitcoin or Ethereum. Fortunately, AION is supported by some very popular crypto exchanges out there such as BitForex, Binance, Ethfinex, Liqui, and Bancor Network. There's a good chance that Aion, with its unique approach of solving interoperability issues, will become somewhat of a necessity for the cryptosphere in the following period.
