What is ARB?

_{What is Arbitrum (ARB)?‍}

Arbitrum (ARB) is a Tier 2 scaling solution for Ethereum designed to improve speed
and reduce the cost of transactions on the Ethereum network using a technology called Rollups.
This allows for higher transaction processing without compromising security

_{Blockchain nativo:}

Arbitrum is a layer-2 L2 (scaling solution) technology for the Ethereum blockchain that enables faster and more economical system operation.
Using Rollup technology, it collects a large number of transactions on Ethereum and then processes them separately from the main network (off-chain).
Before sending it back, check it out on the Ethereum blockchain again. This allows Arbitrum to process transactions faster and more economically than ever before.

ARB is an Arbitrum regular token used for governance by Offchain Labs, the developer behind Arbitrum.
has announced its transition to a decentralized enterprise structure (DAO) called Arbitrum DAO, which holds the ARB token.
You can vote on various proposals that affect features, system upgrades, and resource allocation.
and the election of the Security Council.

_{Protokola Konsensus:}

Arbitrum does not use a consensus protocol to verify transactions directly.
Instead, use the security of the Ethereum network's consensus system, which is currently Proof-of-Stake (PoS).
After The Merge (September 2022)

_{Trilemma (Security, Speed, Scalability):}

Seguridad: Arbitrum uses “Nitro chains” with a Validator system to monitor each other like a watchdog
Everyone checks blocks created by another Validator (RBlocks) if they encounter an error. The system will alert (challenge).
In order to maintain the reliability of the system, however, the Validator also needs to work quickly, because the Arbitrum protocol also has a validation deadline.

snelheid: Arbitrum's system monitors the amount of gas used in each transaction, comparing it with the set value as if it were a “quick channel”.
For transactions (called speed limit), which is analogous to limiting the number of cars on the road, so that the system can process transactions smoothly.
(Arbitrum One currently supports about 7 million transactions per second.)

Scalabilità: Arbitrum addresses existing scalability issues on the Ethereum network
By processing transactions off-chain, this method allows Arbitrum to handle transactions much faster than traditional Ethereum.
(Arbitrum One currently supports millions of transactions per second)

_{Founder/Date Founded:}

Arbitrum was developed by Offchain Labs, a development company based in New York. The founders are Ed Felten, Steven Goldfeder and Harry Kalodner.
All of whom are Princeton University researchers with long experience in computer science, coding, and blockchain.
Ed Felten, a professor of computer science from Princeton, once served as vice president of President Obama's CTO.
Co-Founder and Chief Scientist of Offchain Labs
Steven Goldfeder, computer scientist and businessman, graduated from Princeton.
Co-founder and CEO of Offchain Labs Harry Kalodner
Princeton graduate computer scientist co-founded and serves as CTO of Offchain Labs

_{Objective/Use Case:}

Arbitrum excels in Ethereum network scaling competition with optimistic rollup technology
This makes developers and users choose Arbitrum for the following reasons:
Easy Switch: Existing Ethereum-based applications (dApps) can run on Arbitrum instantly
No code modifications, thanks to EVM contracts and traditional EVM transactions.
Fastand Cheap: Arbitrum supports high transaction volumes (thousands of transactions per second) with low fees
and fast transaction confirmations, both retain the security inherited from Ethereum.
Developer support: Not only Ethereum, but Arbitrum also supports popular programming languages
Like Rust and C++ through future Stylus features
Centralized security system: Unlike other solutions, Arbitrum does not rely on a central administrator
Instead, use a network of validators to secure the system and earn rewards.
Booming ecosystem: The number of DApps, wallets, tools and partners continues to grow.
Making Arbitrum a strong challenger in the field of scale-up

_{Total supply/Limit or Unlimited:}

A total of 10 billion tokens (10 billion) were created with a fixed volume of ARB tokens.

_{Supply Deflation:}

Information on the mechanism for reducing the volume of ARB tokens (tokenomics) is currently unclear.
It is possible that the ARB token does not have a built-in token reduction system, so the total supply may remain constant forever.
