À TOKERO, notre mission est de faire crypto accessible à tous dans un moyen simple, rapide et sûr.


Arbitrum is a Layer 2 scaling solution for Ethereum, designed to address the network's scalability and throughput limitations. It works by creating a trust-minimized "off-chain" execution environment that processes transactions faster and more efficiently than the Ethereum mainnet.

The technology:

At its core, Arbitrum uses a technique called Optimistic Rollups, which is a type of Layer 2 scaling solution that allows for a high volume of transactions to be processed off-chain, while still maintaining the security and integrity of the Ethereum network. This is achieved by creating a "rollup" of multiple transactions, which are then validated on the Ethereum mainnet.

One of the key benefits of Arbitrum is its ability to significantly reduce transaction fees and confirmation times, making it easier and more affordable for users to transact on the Ethereum network. It also allows developers to create more complex decentralized applications (dApps) that require high throughput and low latency, while still leveraging the security and decentralization of the Ethereum network.

In addition to its technical features, Arbitrum also has a strong community of developers and supporters, who are working to build and improve the platform. This includes a robust set of developer tools and documentation, making it easier for developers to build and deploy dApps on the platform. During the last weeks, on Arbitrum there were more transactions than on Ethereum. It gained very much popularity in a short period of time.

DAO & community:

On March 23rd, the Arbitrum team decided to cease most of the power to the community and the project became a DAO. The governance token ARB was minted and the early adopters of the protocol received an Airdrop. The majority (56%) of the Arbitrum token is designated for the community. The Arbitrum Foundation and DAO will be tasked with distributing the additional community tokens over time.

To accelerate this process and make sure that the community remains well represented in the early days, Offchain Labs team members have been instructed not to vote with their tokens, but they are encouraged to delegate them to community members, thereby putting more power in community delegates from the very beginning. At this moment, Arbitrum is one of the "most wanted" projects from the entire crypto space.

Company & team:

Ed Felten, Co-founder & Chief Scientist

Steven Goldfeder, Co-founder & CEO

Harry Kalodner, Co-founder & CTO

Arbitrum Foundation was built by Offchain Labs, a very trusted company from the USA. Prior to the birth of Ethereum, Ed Felten began his extensive research in roll-up technology in 2014. After serving in the White House as President Obama’s Deputy CTO, he returned to Princeton University and resumed his research with Steven Goldfeder and Harry Kalodner, two PhD students at the time. Together, they set out to solve scaling Ethereum without compromising security by creating Arbitrum. With over 8 years of dedicated research and development, they are committed to delivering a robust infrastructure with decentralization and unwavering security.


Arbitrum is a promising solution to the scalability challenges facing the Ethereum network. By leveraging Layer 2 scaling solutions like Optimistic Rollups, it has the potential to significantly increase the network's throughput and make it more accessible and user-friendly for developers and users alike.
