Best Layer 2 Protocols for FastNode

Next generation layer 2 for Ethereum DApps. Scale your dApp with your favorite tools at the lowest possible cost. An aggregator is the same role as a node in Ethereum. Client software can make remote procedure calls (RPCs), to an aggregator using the standard API to interact with an Arbitrum network. The aggregator will then call the EthBridge to produce transaction results to the client just like an Ethereum node. Although it is common for clients to use an aggregator to submit transactions to an Arbitrum Chain, this is not mandatory. There is no limit to the number of aggregators that can exist or who can be an aggregater. In order to improve efficiency, aggregators often combine multiple client transactions into one message that can be submitted to Arbitrum. Arbitrum also supports a privileged Sequencer, which can order transactions and provide low latency transaction receipts.

Polkadot, a blockchain network, is being built to enable Web3.0. This will allow users to control their data and ensure that markets benefit from network efficiency. Gavin Wood, a former co-founder and CTO at Ethereum, founded Polkadot in 2016. Polkadot's technology solves the major problems that have hindered blockchain adoption over the past few years. Parity Technologies created Polkadot's Substrate software development toolkit that allows blockchain developers to create their own custom, fit for use blockchains. Polkadot allows multiple blockchains to communicate with each other, allows for easy upgrades, and introduces "shared Security", a plug and play network security model that allows developers focus on the technology instead of spending time and resources recruiting operators to run a new Blockchain.
