A Beginner’s Guide to Ethereum

When Bitcoin was created in 2009 it sparked a social and technological movement and has since sent ripples across the financial industry.

A promising technology, one often times pushed by the wayside under the guise of “blockchain” or “distributed ledger” in the press. It was the first technology that allowed us to securely send money across the internet, without fear of fraud or censorship. However, several pioneers saw some potential in the underlying technology that powered the secure payment system: the blockchain.

What initially enabled many individuals to send money, also held the potential to decentralize the Internet as we know it.

But there was one caveat (or several for that matter), Bitcoin wasn’t designed to send anything more than a few kilobytes of data per transaction, nor was it capable of performing calculations that didn’t fit into his limited (by design) scripting language. Satoshi Nakamoto, the creator of Bitcoin, believed that limiting the functionality of the system would significantly improve security.

But Vitalik Buterin, the creator of “Ethereum”, saw things a little bit differently. Vitalik imagined Ethereum as a “world computer”; one that fits a virtual machine (the EVM), a Turing-complete language(Solidity, and soon Viper), a token (ETH), and fuel (gas) to power every transaction in its network. This combination allows the creation of complex programmatic computational instructions — commonly known as smart contracts and decentralized applications or “DApps”.

What previously took entire separate tokens and platforms, Ethereum could implement with a few lines of code. Some examples are currently under development or available right to the public: prediction markets, decentralized file storage and computation, insurance contracts, decentralized identity — and much much more.

Ethereum has its own token called “Ether” (ETH); it can be used to pay other people or even machines. In essence, you can send ETH to a smart contract which will then execute itself (ETH is converted to “Gas” when seeking to execute computations in the “EVM”) and perform its a complex set of instructions. With Ethereum, a person can pre-set withdrawal limits; you can even create a smart contract that will send your ether to a loved one when certain conditions are met, such as an outside oracle verifying your death.

The DApps Ecosystem

Golem

Golem is a powerful idea; one if executed appropriately, could lead to huge jumps in the accessibility of developers all over the world to access the same powerful resources to create the next big thing.

Gnosis/Augur

The data can be used by individuals or organizations to make more accurate decisions thanks to the” wisdom of the crowd” –a large group’s aggregated answers to questions involving quantity estimation, general world knowledge, and spatial reasoning has generally been found to be as good as, and often better than, the answer given by any of the individuals within the group.

Augur was launched in 2015, collecting more than $5 million in funding after the Initial Coin Offering (ICO) of its own token, Reputation (REP), to this date, Augur continues its developing phase, with an open beta for users to test. On the other hand, Gnosis is still preparing to launch its own ICO to distribute the tokens that will be used to power the decentralized platform.

uPort

Another problem is that in today’s internet, our identity and reputation is scattered across a myriad of services. If something bad were to happen to eBay’s datacenter, your hard-earned reputation as a merchant would be destroyed forever. Sellers would then have to migrate to another platform and start all over again. A hassle for an individuals whose sole source of income is their reputation as a successful merchant.

Solutions like uPort could help to securely store your encrypted information on Ethereum’s blockchain, allowing you to share it whenever and with whoever you want to.

Status

Applications like Status are huge for Ethereum, as it blends a traditional messaging client, and a platform to quickly create and maintain a wallet/profile that you can then use to easily access the Ethereum network.

Status aims to make the barrier to entry to Ethereum low; and allows for somewhat of an Ethereum DApp store on your mobile device.

WeTrust

ROSCAs built on WeTrust enable low-cost savings like accounts for participants (friend & family) to trustlessly save money; and have a pool of funds to full from in time of emergency, or when needing to make a large purchase (think car down payment).

WeTrust lower costs and grants users greater privacy and control over your personal financial data. Their system introduces the ability to create networks of wealth easily, anywhere. Users can share funds based on self-reliance and take back power; rather than grant more to corporate, institutional or governmental agencies.

Just a Taste

Ethereum itself, the core protocol, is constantly undergoing improvements through a series of pre-planned hard forks (upgrades); and sometimes some are unplanned (emergency upgrades). But, overtime, the ecosystem of DApps built on this public system will eventually interoperate to form the basis of the next generation of the internet.
