On Friday, the Arbitrum team announced via X that ArbOS Elara is live on the Arbitrum Platform, bringing new capabilities to dedicated blockchains and important improvements to Arbitrum One.
ArbOS Elara adds support for priority fee collection on dedicated blockchains, giving chain operators another configurable tool for transaction ordering and fee-market design. Priority fees allow transactions to include tips that influence transaction ordering, creating greater flexibility for chains with advanced execution, trading, or application-specific requirements.
Importantly, this upgrade establishes the underlying capability required for future priority fee collection on Arbitrum One, an important step toward implementing Priority Gas Auction (PGA) transaction ordering for the network. This potential upgrade is being discussed separately through ArbitrumDAO governance.
The new Alternative Data Availability (AltDA) API enables chain operators to integrate data availability providers without maintaining custom Nitro forks. This significantly reduces long-term maintenance requirements and allows teams to focus on product development rather than infrastructure upkeep.
Arbitrum One now uses a BaseFeeManager contract that allows the network to respond more effectively to changing market conditions that affect user costs, spam resistance, network activity, and fee revenue.
Arbitrum is an Ethereum layer-two (L2) scaling solution. It uses optimistic rollups to achieve its goal of improving speed, scalability, and cost-efficiency on Ethereum. Arbitrum benefits from the security and compatibility of Ethereum. Another benefit is the higher throughput and lower fees compared to Ethereum. That is made possible thanks to moving most of the computation and storage load off-chain.
Arbitrum’s native token is called ARB and is used for governance. Offchain Labs, the developers behind Arbitrum, announced the shift to a decentralized autonomous organization (DAO) structure — the Arbitrum DAO. ARB holders can vote on proposals that affect the features, protocol upgrades, funds allocation, and election of a Security Council.
Arbitrum uses optimistic rollups to stand out from other scaling solutions for Ethereum. It claims to offer several advantages over other optimistic rollup solutions, such as:
Compatibility: Arbitrum supports unmodified EVM contracts and transactions, meaning that any existing Ethereum DApp can run on Arbitrum without any code changes.
ARB, the native coin of the Arbitrum network, is up 3.1% today and is trading at $0.09939.
