Arbitrum Shared Node

Launched by New York-based development firm Offchain Labs, Arbitrum is a Layer 2 solution for Ethereum dApps intended to increase scalability, privacy and speed of EVM smart contracts, while also retaining security benefits provided by Ethereum.

When compared to Ethereum, which is able to manage roughly 14 TPS, Arbitrum runs 40,000 transactions per second.

It is much cheaper (about two cents vs several dollars) and easier to use. Besides, Arbitrum offers thorough toolkit documentation for developers working or beginning to work with the platform.

That is to say that the Arbitrum network seeks to minimize any sort of limitations between developers and the final product, and make the entire process more efficient.

GetBlock’s shared node solution guarantees fast and easy access to Arbitrum’s peer-owned node architecture.

As its primary scalability solution, Arbitrum utilizes a technology called optimistic (transaction) rollup. The unique protocol allows transaction execution of Ethereum-based smart contracts on the Arbitrum L2 chain.

The Arbitrum rollup is different in the sense that not every transaction needs to be verified. Validators assume that the execution is correct; however, it is possible to dispute the assertion if the dishonest behavior is suspected by at least one validator. The term “rollup” is used to describe the ability of validators to reconstruct the historical log of events conducted on the chain.

Not unlike Ethereum nodes, Arbitrum aggregators allow for the developer’s software to interact with the Arbitrum network by implementing the standard API. The aggregator’s main role is to make a call to EthBridge and process a transaction.

Next up, the transaction is posted on the Ethereum main net. It is transparent, meaning all users can see it, and once it reaches its final stage it cannot be re-reordered.

After the transactional data is made visible to Ethereum users, it is then forwarded into the hands of Arbitrum validators. They assert the process of transaction rollup, and the assertion is therefore posted on the Ethereum chain optimistically, with no proof required.

Once the transaction is asserted, it is possible to challenge it. Thereby, at this stage validators can prove fraud if it is found. Those who are able to recognize fraud are rewarded. Cheaters, however, lose a large sum of money which substitutes for the rewarding amount.

Arbitrum is a go-to L2 choice for many dApp developers around the world. Arbitrum offers cost and time-efficient services for its clients designed to make the process of decentralized application development accessible to everyone and offload Ethereum mainnet.

With GetBlock, a top-notch blockchain nodes provider for 40+ networks, clients are instantly connected to Arbitrum shared nodes. Crypto developers and businesses can test their decentralized applications under real conditions. There is also a one-month free trial available for beginners.
