Ethereum (ETH): What is it? The complete beginners guide

0

Ethereum was launched in 2015. The vision behind Ethereum was to improve upon bitcoin.

Ethereum is an open-source platform for building and deploying decentralised applications i.e. dApps. Its native currency, Ether (ETH) serves as “gas” for running computations and transactions for dApps.

Main features of Ethereum

  • Decentralised: No one party has majority control over the Ethereum network’s computing power.
  • Ether is a cryptocurrency: It can be used as “gas” to power dApps and is a store of value.
  • Automatic: Processes on the network can be executed without human intervention.
  • Public: It is accessible by anyone with a computer and internet connection.

What are dApps?

Users can build and run decentralised applications (dApps) on the network. They serve some particular purpose to its users and must have these common features:

  1. Open source: The dApp’s source code must be publicly available. Changes to the source code require agreement by a majority of users.
  2. Decentralized: Records of how the dApp were used are stored on a public blockchain. This blockchain is not subject to any controlling entity.
  3. Incentivized: dApps must use and provide its unique tokens or digital assets to users as a reward for their contribution.
  4. Protocol: The community of users must agree on a cryptographic algorithm to show proof of value. Ethereum is currently using Proof of Work as its distributed consensus system. In future, this will change to Proof of Stake (PoS). Learn more about Proof of Stake.

Examples of dApps include:

  • Enjin: a suite of products for creating, storing trading and integrating blockchain-based in-game assets. Learn more about Enjin here.
  • Bancor: a token exchange.

Future of Ethereum

Ethereum’s latest upgrade, “Constantinople” was launched on 28th February 2019.

The next upgrade “Istanbul” is tentatively scheduled for 16th October 2019. It will have several updates. These include a new Proof of Work Algorithm designed to close the efficiency gap available to specialised ASIC miners.

Click here for a list of the upgrades under the Istanbul upgrade.

The ecosystem will gear up towards “Ethereum 2.0”- known as “Serenity”. Its major update will be a shift from Proof of Work to Proof of Stake.

Learn about how Ethereum’s shift to Proof of Stake and how this will affect users.
