↳ Smart Contracts
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.
In ETH 2.0, Ethereum will be moving to a different system called “Proof of Stake”. Read more about ETH 2.0 below.
↳ Clients and Nodes
The Ethereum network is made up of many nodes, each of which runs compatible client software. There are two clients that are used by a majority of nodes: Geth (written in Go) and Parity (written in Rust).

↳ Enterprise Ethereum
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 1” refers to improving the core Ethereum protocol. The primary project to improve Ethereum’s core protocol is ETH 2.0.
“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.

↳ ETH 2.0
ETH 2.0 (also known as “Serenity”) refers to the next major upgrade of the core Ethereum protocol. It combines several improvements to Ethereum’s core protocol, or “Layer 1”.

↳ ETH 1.x
ETH 1.x is the name for a collection of upgrades to the existing Ethereum protocol. The goal is to continue to improve and maintain Ethereum while ETH 2.0 is developed and implemented.
For more information, see EthHub’s explainer page about ETH 1.x
“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.
