Summary: Ethereum was conceived in 2013 by programmer Vitalik Buterin. A decentralized, open-source blockchain with smart contract functionality.


Vitalik Buterin is a young programmer and entrepreneur who is best known for his work on Ethereum, a decentralized platform that allows developers to build and deploy applications on the blockchain.

Buterin was born in Russia in 1994 and moved to Canada with his family at the age of six. He first became interested in cryptocurrency in 2011, when he was just 17 years old. He was fascinated by the idea of a decentralized, peer-to-peer system for exchanging value and began writing articles about Bitcoin and other cryptocurrencies for various online publications.

In 2013, Buterin co-founded Ethereum with several other developers. Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third-party interference.

Ethereum is built on top of the blockchain, a distributed ledger technology that allows for secure and transparent record-keeping. The blockchain is made up of a network of computers (called nodes) that work together to validate and record transactions. The blockchain is secured using cryptography, which makes it almost impossible to hack or manipulate the data stored on it.

One of the key features of Ethereum is its ability to execute smart contracts. A smart contract is a self-executing contract with the terms of the agreement between buyer and seller being directly written into lines of code. The code and the agreements contained therein are stored on the blockchain and are enforced automatically.

An example of a smart contract could be an agreement between a car dealership and a customer to purchase a car. The terms of the contract, such as the price of the car and the delivery date, are written into the code of the smart contract. When the customer pays the agreed-upon price, the smart contract is automatically executed, releasing the car to the customer and transferring the ownership to them.

Another example of a smart contract could be a crowdfunding campaign. A project creator can set up a smart contract that outlines the terms of their campaign, including the amount of money they are trying to raise and the rewards they will offer to backers. When backers contribute money to the campaign, the smart contract is automatically executed, releasing the rewards to the backers once the campaign reaches its fundraising goal.

Ethereum has the potential to revolutionize the way we do business and interact with one another. It allows for the creation of decentralized applications (DApps) that are not controlled by any single entity, but rather run on a decentralized network of computers. This means that DApps cannot be shut down or censored by any one party, making them more resilient and trustworthy.

One example of a DApp built on Ethereum is Cryptokitties, a game that allows users to breed and trade virtual cats. The game uses smart contracts to manage the ownership and breeding of the virtual cats, ensuring that the rules of the game are followed and that players can trust that their virtual cats are truly owned by them.

Another example of a DApp built on Ethereum is Augur, a decentralized prediction market platform. Users can create markets for various events, such as political elections or sporting events, and bet on the outcome. The results of the events are then reported by a network of oracles (individuals or organizations that provide real-world information to the platform) and the smart contracts on the platform automatically payout to the correct parties.

Ethereum has the potential to disrupt a wide range of industries, including finance, insurance, and even the legal industry. Its ability to execute smart contracts automatically and transparently has the potential to streamline many processes and reduce the need for intermediaries.
