Ethereum is the community-run technology powering the cryptocurrency, ether (ETH) and thousands of decentralized applications. Ethereum is a technology that's home to digital money, global payments, and applications. The community has built a booming digital economy, bold new ways for creators to earn online, and so much more. It's open to everyone, wherever you are in the world – all you need is the internet. Today, billions of people can’t open bank accounts, others have their payments blocked. Ethereum's decentralized finance (DeFi) system never sleeps or discriminates. With just an internet connection, you can send, receive, borrow, earn interest, and even stream funds anywhere in the world. Today, we gain access to 'free' internet services by giving up control of our personal data. Ethereum services are open by default – you just need a wallet. Stake your ETH to become an Ethereum validator.

Next generation layer 2 for Ethereum dApps. Use your favorite tools and scale your dApp at the lowest cost. An aggregator plays the same role that a node plays in Ethereum. Client software can do remote procedure calls (RPCs) to an aggregator, using the standard API, to interact with an Arbitrum chain. The aggregator will then make calls to the EthBridge and produce transaction results to the client, just as an Ethereum node would. Most clients will use an aggregator to submit their transactions to an Arbitrum chain, although this is not required. There is no limit on how many aggregators can exist, nor on who can be an aggregator. To improve efficiency, aggregators will usually package together multiple client transactions into a single message to be submitted to the Arbitrum chain. Arbitrum also supports a privileged Sequencer that can order transactions and give low latency transaction receipts.
