All blockchains face the \"Blockchain Triangle Dilemma\" when they are developed: decentralization, security, and scalability. Each blockchain can only solve 2 of these 3. In Ether, it is decentralized and secure, but lacks scalability, hence the existence of Layer 2.<\/span><\/span><\/div><\/div><\/div>

Layer 2\u00a0<\/span><\/span>Currently there are<\/span><\/span>six<\/span>Solutions, mainly consisting of State Channel, Side Chain, Plasma, Optimistic Rollups, Validium, Zk-rollups.

What exactly is Rollup?<\/h1>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Layer 1 of the blockchain is the most basic of the main blockchains, in Ether, users reach consensus and build applications. When Layer 1 becomes congested, you can have a smart contract to connect to Layer 2 off the main chain, where transactions can be quickly processed and then packaged back to the main chain where they can be verified.<\/span><\/span><\/p>\n

Layer 2 is an additional blockchain that is more efficient and less costly than the main Ethernet network. Rollup is a very clever scaling solution that moves the computation process from the main chain to a separate chain called the \"Rollup chain\", where transactions are executed, data is aggregated and pooled together, and then passed back to the main chain for validation. Since the algorithmic process takes place outside of the main chain, less data is logged into the blocks of the main chain, making the main chain's (Ethernet's) network less congested.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

What are Optimistic Rollups?<\/h1>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Optimistic Rollups use a technique called \"proof of fraud\". Optimistic Rollups do not perform any algorithms because they run concurrently with the ethereum mainchain, and after a transaction has been processed, they simply post the data to the mainchain and assume it is correct, hence the name Optimistic. Because<\/span><\/span>It would be assumed that the world is full of good people.<\/span><\/span><\/p>

Optimistic Rollups has a mechanism called the Dispute Resolution System.<\/span><\/span><\/p>

First.<\/span><\/span>The party submitting the transaction to the Master Chain must first provide margin.<\/span>This margin is usually denominated in ETH.<\/span>If someone sends a fraudulent transaction from the Rollup chain to the master chain in bad faith, the system will penalize that user. If other users in the Rollup network discover invalid or fraudulent transactions, they can submit proof of fraud. By submitting a Fraud Proof, which requires an upfront deposit, the transaction will run again, but this time on the Etherium main chain. If the transaction is found to be truly fraudulent, the user who submitted the fraudulent transaction will lose their margin.<\/span><\/p>

Simply put, the Dispute Resolution System is two-way; the party that submits a Proof of Fraud must also submit a Margin, and if it is ultimately proven that the transaction was not fraudulent, that party also loses the Margin, thus ensuring that the network is not overloaded with multiple, unnecessary Proofs of Fraud.<\/span><\/span><\/p>

As a minimal extension to existing Ether software, Optimism's EVM-equivalent architecture scales Ether applications, meaning that if it works on Ether, it works on Optimism.<\/span><\/p><\/div><\/div><\/div>

Optimism utilizes a single round of fraud proofing, where Layer 1 executes the entire Layer 2 transaction on the chain to verify the root state, making fraud proofing instantaneous, which is an advantage. According to DefiLlama, Optimism's total lockup on the chain is currently worth about $810 million. Many well-known DeFi projects are also deployed on Optimism, such as Synthetix, Curve, AAVE V3, Uniswap V3, and so on.<\/span><\/span><\/p>

Bridging assets such as ETH to Optimism is the first step in exploring the Optimism ecosystem, either through the official Optimism bridge or any other applicable cross-chain bridge, and after bridging to Optimism, you can mint the official NFTs as well. users can also choose to coin items that are not yet coins in the Optimism ecosystem, thus killing two birds with one stone!<\/span><\/span><\/p>

Arbitrum uses Rollup expansion technology. When the Layer 1 blockchain network is congested, the smart contract connects it to the Arbitrum backbone in Layer 2, moving complex and computationally heavy work to L2, and then packages and transfers the records back to the ethereum blockchain, thus saving ethereum's computing power.<\/span><\/span><\/p><\/div><\/div><\/div>

Arbitrum uses multiple rounds of fraudulent proofs to find the first operand of the block that caused the disagreement by binary search. Once found, it is simply executed on the chain. Of the many scaling options available for Ether, Arbitrum is the number one lock-in for the time being. According to DefiLlama data, Arbitrum's total lockup is currently around $1.04 billion.<\/span>Steady upward trend since July 2022<\/span><\/span>\u3002<\/span>Of course, this is due to the ecosystem of projects in the Arbitrum chain, including stars such as GMX, Sushi, Uniswap V3, Curve, Stargate, Radiant and many more.<\/span><\/p>

Arbitrum has its own official cross-linking bridge, which allows users to cross-link Ether assets to the Arbitrum chain to participate in the above program by simply connecting to a cryptocurrency wallet. However, if you want to cross-link assets from Arbitrum back to Ether, you need to wait 7 days for the cross to complete. Therefore, some people choose to use other unofficial bridges such as the Hop Protocol to cross-link their assets, but this involves additional Gas fees or cross-linking through a supported exchange (Bybit, Binance). In addition, the official Arbitrum bridge only supports cross-chaining with Ether, and the most popular Arbitrum wallet in use today is Metamask.<\/span><\/span><\/p>

How to increase your chances of getting an Arbitrum drop? Save this guide<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

I. Buying ETH<\/span><\/span>
<\/b>The first step you need to take to get the best chance of winning an Arbitrum Airdrop is to acquire ETH, the native cryptocurrency of the Ether network. ETH can be used to pay for transactions on both the main Ether network and Arbitrum. You can do this via the Binance<\/a><\/span>\u3001Bitget<\/span><\/a> \u6216 Bybit<\/span><\/a> The ETH can be purchased on centralized cryptocurrency trading platforms such as<\/span><\/span><\/p>\n

Once you have acquired ETH, transfer it to the Hot Wallet of your choice. To ensure that your Hot Wallet supports ETH or runs on the main Ether network, it is recommended that you choose a popular wallet that supports ETH. MetaMask<\/b>It is an ethereum-compatible wallet that can connect to hundreds of decentralized applications (dApps).<\/span><\/span><\/p>\n

Connecting Arbitrum to MetaMask<\/span><\/span>
<\/b>To view ETH in your wallet, you need to add the Arbitrum network to your MetaMask (or other soft wallet of your choice), this is a very simple step to do, and is a \"one-click\" process for MetaMask.<\/span><\/span><\/p>\n

You can visit the Arbitrum Bridge website and click \"Add\/Switch\" to the Arbitrum network, after which you will receive a pop-up message from MetaMask, click Approve and the Arbitrum network will be added to your MetaMask wallet.<\/span><\/span><\/p>\n

III. Bridging Funds to Arbitrum<\/b><\/span><\/span>
After purchasing ETH, the next step is to transfer your ETH from the main Ether network to the Arbitrum network, which can be done in a few minutes.<\/span><\/span><\/p>\n

Currently the main bridging methods include:<\/span><\/span><\/p>\n

1\u3001Centralized Bridge: Binance, Bitget, Bybit<\/span><\/span><\/p>\n

2. Local Native Bridging: Arbitrum Bridge (it is said that using the Arbitrum Native Bridge has a better chance of qualifying for potential future airdrops)<\/span><\/span><\/p>\n

3\u3001Third-party bridge: Hop Exchange, Celer Bridge, Connext Bridge, etc.<\/span><\/span><\/p>\n

IV. Completion of the tasks in the chain<\/b><\/span><\/span>
Once you have bridged your ETH to the Arbitrum network, you will be able to complete a number of tasks on the Arbitrum chain that will grant you access to the Arbitrum Guild. Currently, there are no benefits to joining the Arbitrum Guild at this stage other than your role in the official Arbitrum Discord, but joining the Guild is a good starting point for new users. You can visit the official website of the Guild and complete the necessary tasks.<\/span><\/span><\/p>\n

V. Weekly Arbitrum interactions<\/b><\/span><\/span>
If you want to increase your chances of qualifying for an Arbitrum Airdrop, you need to interact with Arbitrum on a regular basis - daily or weekly - and this is very important to ensure that you are an active user of the chain.<\/span><\/span><\/p>\n

It's not a difficult step to perform, and you need to use the Arbitrum protocol as much as possible, such as trading Token Swaps, adding liquidity, or pledging in a liquidity pool.<\/span><\/span><\/p>\n

Up to now, Arbitrum officials have not made any explicit statement on how much ETH (or other Token) can be transferred to qualify for airdrops, so you can determine the amount of assets to be kept on the Arbitrum network according to your own risk tolerance.<\/span><\/span><\/p>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
