1 ETH = 0.06833 BTC
Ethereum is a technology that lets you send cryptocurrency to anyone for a small fee. It also powers applications that everyone can use and no one can take down.
It’s the world’s programmable blockchain.
Ethereum builds on Bitcoin’s innovation, with some big differences.
Both let you use digital money without payment providers or banks. But Ethereum is programmable, so you can also use it for lots of different digital assets – even Bitcoin!
This also means Ethereum is for more than payments. It’s a marketplace of financial services, games and apps that can’t steal your data or censor you.
So step into the bazaar and give it a try…

Ethereum is open access to digital money and data-friendly services for everyone – no matter your background or location. It’s a community-built technology behind the cryptocurrency ether (ETH) and thousands of applications you can use today.

- Ethereum’s original Whitepaper
A “smart contract” is simply a piece of code that is running on Ethereum. It’s called a “contract” because code that runs on Ethereum can control valuable things like ETH or other digital assets.

Proof-of-work and Mining
Ethereum currently uses a system called “proof-of-work”. This allows the Ethereum network to agree on the state of all information recorded on the Ethereum blockchain, and prevents certain kinds of economic attacks.

Clients and Nodes
The Ethereum network is made up of many nodes, each of which runs compatible client software.
Enterprise Ethereum refers to private, consortium, and hybrid implementations of the Ethereum codebase for business applications. Companies across the globe are already using Enterprise Ethereum to streamline financial markets, manage supply chains, and create new business models.

Improving Ethereum’s scalability
There are many efforts underway to make Ethereum more “scalable” by improving its speed and overall transaction throughput. Generally these are sorted into “Layer 1” and “Layer 2” solutions.
“Layer 2” refers to technologies that are built “on top” of the base Ethereum protocol, enabling greater scalability without compromising on security. There are also “off-chain” technologies like side-chains, which enable greater scalability by making a different set of security tradeoffs.
Consensus layer upgrades
A set of upgrades (originally known as ‘Serenity’ or ‘Eth2’) that aim to upgrade the Ethereum protocol’s core for a more scalable, sustainable future, utilizing a proof-of-stake consensus layer.
Execution layer upgrades
Execution layer upgrades are a separate area of research from the consensus layer. The goal is to continue to improve and maintain the execution layer of Ethereum while the consensus layer is developed and implemented.
For more information, see EthHub’s explainer page about Ethereum’s execution layer.
“Cryptoeconomics” is the practical science of building distributed systems, where properties of those systems are secured by financial incentives, and where the economic mechanisms are guaranteed by cryptography. It is the general term for the practice of designing and scaling blockchains like Ethereum and Bitcoin.
