What is Arbitrum (ARB)?
Arbitrum is a layer-2 scaling solution that aims to improve the speed and efficiency of Ethereum transactions while also reducing the high fees associated with using the platform.
Arbitrum mainnet was launched in 2021 by Offchain Labs, and it has quickly become one of the most popular blockchains in the market. At the beginning, Arbitrum achieves this by using Optimistic Rollups. In the later half of 2022, Arbitrum released Nova, a new chain using AnyTrust technology instead of Optimistic Rollups, and the old chain was renamed to Arbitrum One.
For two years of its operations, Arbitrum does not have its own native token to power the network like other layer-2 solutions, such as Polygon or Optimism. The blockchain plans to release its own token, ARB, which can be used to support DAO voting, towards the end of March 2023.
How Arbitrum (ARB) Works
Arbitrum One uses Optimistic Rollups to process and bundle multiple transactions into a single batch, which was then settled on the Ethereum network. The bundles of transactions are assumed “innocent until proven guilty” by Ethereum, hence the name “Optimistic”.
With AnyTrust technology, Arbitrum Nova can be used for more cost-sensitive use cases. Nova first sends data to the committee, and only puts data on-chain if the committee, for some reasons, fails to do its job. Therefore, transactions on Nova will have significantly lower transaction fees compared to Arbitrum One, making it more suitable for projects with high transaction volume expectations.
How Many Arbitrum (ARB) Tokens Are in Circulation?
ARB plans to have a total supply of 10,000,000,000. The amount of ARB in circulation is unknown.

Located in Southeastern Europe and forming part of the Balkans is Montenegro, a nation that shares its borders with Serbia to the northeast, Croatia to the northwest, Bosnia and Herzegovina to the north, Kosovo to the east, Albania to the southeast, and the scenic Adriatic Sea to the west. Its coastline for the latter runs a whopping 293.5 kilometers long, with its capital city Podgorica located inland to the east. The city spans 13,812 square kilometers and is home to around 30% of Montenegro’s overall population of 621,000. There, you’ll find plenty of culturally-rich museums and art galleries, including the city’s main museum and the Center for Modern Art.
Due to the diversity of its landscapes which stretch from the coast of the Adriatic Sea to the mountain ranges of Durmitor, Bjelasica, Sinjajevina, Prokletije, Komovi, and more, the country attracts approximately 1.3 million tourists every year. Interestingly, more than 60% of the nation sits at an altitude of 1000 meters above sea level or more, meaning you’ll be able to ski up in the mountains and swim in the sea on the same day during mid-season changes. There are also four national parks, with Durmitor National Park earning the title of a UNESCO World Heritage Site.
Currently in the process of joining the European Union, Montenegro has adopted the Euro (EUR) as its official currency, and with direct support from Bitget, you can purchase Arbitrum(ARB) in just a matter of minutes, no matter where you are in the country, from Podgorica to Nikšić to Herceg Novi.
