The Ethereum Foundation envisioned Ethereum as a decentralized computing platform that enables anyone to create, store, and run smart contract-based Decentralized Applications, or DApps.

As the below diagram shows, an Ethereum blockchain network is a decentralized Peer-to-Peer P2P network of Ethereum clients, representing network nodes. An Ethereum client refers to any node that can verify the new transaction, execute the smart contract, and process new blocks of the chain. It is a kind of enclave, residing in thousands of computers or devices on the internet, and connected through the Ethereum P2P network.

The following diagram shows the P2P network:. Ethereum clients run the EVM and can technically be written in any popular programming language. There are many different implementations of Ethereum clients. There are many advantages with such a variety of Ethereum client implementations, including the following:.

From your web or wallet application, you can use the web3 object provided by the web3. It works with any Ethereum client. Behind the scenes, it connects to a local or remote Ethereum node and makes RPC calls. In some sense, this is like the old client-server model, where DApps are the client, and the entire Ethereum network as a whole, acts as a server. To DApps, the Ethereum network is just like a giant world computer, assembled together with thousands of computing devices throughout the internet.

Once you connect to the network, you could connect to any node in the decentralized network, as shown in the following diagram:. Beyond smart contracts and the EVM, an Ethereum client provides all blockchain components to maintain world state and state transitions in the blockchain network, including the following:.

We will discuss more details on world state in the next section. For other technical concepts, you can refer to the Ethereum documentation page. The design behind Ethereum, based on the whitepaper, is intended to build a simple, efficient and extensible blockchain platform, and have a Turing-complete program language to support more sophisticated and complex computations.

It not only has all of the benefits of a blockchain but can serve as the framework for supporting all types of digital assets and value transfers as well. Ethereum is often dubbed as the world computer in the decentralized world. What does that mean? How does Ethereum fulfill the tall order of the humongous computation needed in the digital world? Let's start with the history of the internet and web and discuss the potentials of Ethereum.

The World Wide Web started as the decentralized content network in the early '90s. It is designed for people to publish and share content without going through any central authority or intermediary.

But from the early s, with the advent of e-commerce, social and mobile, collectively called Web 2. Thanks to the power of platforms, platform businesses such as Uber, Airbnb, and Facebook managed to disrupt traditional business models and dominate vast traditional industries within just a few years of their own launch and outcompeted the traditional companies with a tiny fraction of the number of employees and resources. The direct consequence of such platform success is all that user data concentrated in the hands of a few, creating risks that our data will be misused or even hacked.

It also makes it easier for governments to conduct surveillance and impose censorship. Blockchain is on the way to become the new internet, Web 3. Bitcoin laid a foundation of decentralization with its shared public ledger, a digital cryptocurrency payment model, and P2P technology.

Ethereum took this model further beyond finance and P2P payment, which propelled the creation of a new business model called DApp. A DApp is an application or service that runs on a blockchain network and enables direct interaction between consumers and providers, for example, connecting buyers and sellers in a decentralized marketplace. Similar to the centralized application architecture, a DApp usually involves a decentralized backend that runs on the blockchain network and a centralized frontend that allows end users to access their wallets and make a transaction.

The below diagram shows the differentiation between centralized and decentralized applications:. Although there are many different viewpoints, it is a common belief that a DApp must be completely decentralized and open source. It must run on a blockchain network and use and generate cryptographic tokens. Most DApps often start with a whitepaper and a working prototype.

Instead, as a DApp, Ethereum provides a platform for anyone to write smart contracts and decentralized applications based on your business needs and value propositions. It is intended as the world computer for the decentralized world. As such, Ethereum provides four decentralized computing facilities, along with a large list of development and testing tools, which make it very easy to develop and deploy DApps on to the Ethereum blockchain.

The four decentralized computing facilities are as follows:. In this article, we briefly reviewed the architecture and components behind Ethereum. Along the way, we learn about characteristic and architecture of decentralized networks and in what ways they outperform traditional centralized networks.

It prevents the centralization of developer resources. In general, competitions between teams help to find the best solutions to common and challenging issues. Each client may have a different focus, strength, and weakness in mining, prototyping, DApp development, and more. DApp developers or private Ethereum blockchain operators may choose the ones fitting their own special needs.

You will work on a virtual machine image, specifically created for this course, to build an Ethereum test chain and operate on the chain.

Ethereum Architecture

This post walks through the steps to creating a simple Ethereum DApp using Web3. This article also provides explanation of various pieces of technology involved in developing DApps. Decentralized Applications or DApps are applications that do not rely on a centralized backend running in AWS or Azure that power traditional web and mobile applications outside of hosting the frontend code itself. These blockchain nodes do not require a leader which would defeat the purpose of being truly decentralized. These nodes are untrusted nodes running in an arbitrary sized network on various compute devices around the world.

Review of Architecture and Components of Ethereum

Help us translate the latest version. The Ethereum protocol itself exists solely for the purpose of keeping the continuous, uninterrupted, and immutable operation of this special state machine; It's the environment in which all Ethereum accounts and smart contracts live. At any given block in the chain, Ethereum has one and only one 'canonical' state, and the EVM is what defines the rules for computing a new valid state from block to block. Some basic familiarity with common terminology in computer science such as bytes , memory , and a stack are necessary to understand the EVM. The analogy of a 'distributed ledger' is often used to describe blockchains like Bitcoin, which enable a decentralized currency using fundamental tools of cryptography. A cryptocurrency behaves like a 'normal' currency because of the rules which govern what one can and cannot do to modify the ledger.

Researchers at ETH Zurich have used 3D-printed formwork elements made from recyclable mineral foam to create a pre-cast concrete slab, which they say is lighter and better insulated while using 70 per cent less material. Researchers from ETH Zurich are building a tall architectural structure that will evoke the Hanging Gardens of Babylon, in a project that involves working collaboratively with robots. Researchers at ETH Zurich have created a machine that controls the setting rate of concrete to offer a "seamless transition between casting and 3D printing " so that structures can be made that use less material. A Room for Archaeologists and Kids by Studio Tom Emerson and Taller 5, which won the Dezeen Awards architecture project of the year award, shows that architecture "does not need to be complicated", says judge Lyndon Neri in this movie.

A blockchain is a growing list of records , called blocks , that are linked together using cryptography. The timestamp proves that the transaction data existed when the block was published in order to get into its hash. As blocks each contain information about the block previous to it, they form a chain, with each additional block reinforcing the ones before it. Therefore, blockchains are resistant to modification of their data because once recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks. Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger , where nodes collectively adhere to a protocol to communicate and validate new blocks.

Zurich, November — With the help of artificial intelligence and four collaborative robots, researchers at ETH Zurich are designing and fabricating a Soaring to a height of The sculpture, named after the Babylonian queen to whom the ancient Hanging Gardens of Babylon have been attributed, is being designed and built using innovative digital methods that were developed as part of the project. In the conventional design process for projects like this, architects try to take the different requirements of a building or structure into account in its design, and then adjust that design until all the requirements are met in the best way possible.
