<p>Blockchain technology cannot be argued is increasingly getting attention by individuals from all over the world. Blockchain is a decentralized network which does not allow control by the centralized authorities, therefore these can bring advantages and disadvantages at the same time. User experience is one of the major concerns in blockchain tech, for instance high transaction fees and congestion in the network can bring negative effects to blockchain technology. Therefore, developers have come with a solution; Rollups.&nbsp;</p> 
<h2 class="wp-block-heading" id="strong-layer-2-rollups-strong"><strong>Layer 2 Rollups.</strong></h2> 
<p>Rollups execute transactions outside the major ethereum blockchain and then send back the transaction information inside the main Ethereum network. They are frequently referred to as off-chain scalability solutions, for instance they process off-chain information, after that they convert these information to a single piece of data and send them to the main Ethereum chain network or on-chain network.&nbsp; But the <a href="https://www.thecoinrepublic.com/2023/09/24/chainlink-taps-eth-layer-2-protocol-for-cross-chain-development/" rel="noopener noreferrer nofollow">Layer 2</a> rollups bring improved scaling solutions to the Ethereum network. For instance the rollup in L2 is responsible for rolling up transactions by batching them immediately before publishing them in L1.&nbsp;&nbsp;</p> 
<h2 class="wp-block-heading" id="strong-how-verifiers-secure-layer-2-rollups-strong"><strong>How Verifiers Secure Layer 2 Rollups.</strong></h2> 
<p>Layer 2 consists of two networks; verifiers nodes and sequencers. These two networks function differently on the Ethereum network. For instance, the sequencer performs transaction duties. The receive transaction and then conducts the transaction by how the sequences were received in the network. After conducting the transactions they generate batches for each transaction and a final state root. The update is then confirmed anytime a transaction or signature is required to look at whether it’s on-chain or off-chain transactions. The transaction data and batch state is posted in the verifier’s contract. The verifiers come into play here since the ORUs don’t perform this action and rely on third parties for verification of transactions to occur.&nbsp;</p> 
<p>Therefore verifiers secure the layer 2 Rollups in many ways, for instance verifiers play a crucial role in data availability in layer 2 rollups, being a scaling solution in L2, they aid in executing off-chain transactions before posting the data in base layer and batches.&nbsp; The data availability permits investors and users to conduct trustless verification and correct data. Then ensures a corresponding information in L1 and L2.&nbsp;</p> 
<p>Verifiers ensure secured transactions in layer 2. For instance they detect fraud and scammers activities on the network. For instance, for a transaction to be conducted in layer 2, there should be corresponding information between L1 and L2. practically the verifiers get both LI and L2 transactions, correspond the information and oversees if they are corresponding. If they detect any kind of fraud they raise alarms to individuals.</p> 
<p>&nbsp;Verifiers often are decentralized in blockchain, they ensure that rules and control of these assets are not centralized. For instance, verifiers need verification of nodes in L1 and L2, the decentralization of these nodes provide a flexible verification and they can participate in making rules through voting. They therefore give each individual control of their digital assets ensuring no single person controls the whole verification process.&nbsp;</p> 
<h2 class="wp-block-heading" id="strong-how-fraud-proof-secure-layer-2-rollups-strong"><strong>How Fraud Proof Secure Layer 2 Rollups.</strong></h2> 
<p>Fraud proof consists of two categories; interactive and non-interactive fraud proofs. They both conduct a resolution that is not correct. For instance verification of transactions are needed to pass through the fraud proof to initiate the validation process that is correct.&nbsp;&nbsp;</p> 
<p>Non-interactive fraud proofs don’t require third parties in order for the system to prove the incorrectness of an assertion. For an assertion to be validated, they run the two assertions to establish whether it’s consistent or not. Although they are easy to implement and use, they come with limits. For instance the size of an assertion needs to be smaller in size. The size of the assertion is required to be small to be passed through EVM.&nbsp;</p> 
<p>Interactive fraud proof works totally opposite of non-interactive fraud proofs. For instance it involves two parties, the two parties present an assertion. One party claiming the assertion is a fraud and the other one defending the assertion. Therefore, the fraud proof works to prove a correct assertion. The fraud proof therefore interacts with the two parties and comes to a single state transition. The correct assertion is validated. This ensures that no limitations are set on L1 since the produce assertion is smaller in size.</p> 
<p>The fraud proof in securing layer 2 in blockchain plays a vital role in the blockchain technology, they protect layer 2 in order to provide a scalable throughput and a secure transaction. For instance they provide a correct validation. Layer two should consume a correct transition. The fraud proof therefore ensures this happens by ensuring only the correct assertions are passed through. They contain mechanisms which counter check these assertions to ensure that they are valid and not malicious to L2.&nbsp;</p> 
<p>Layer 2 majorly focuses on off-chain transactions, but for a certain transaction to occur they are needed to be validated. Therefore they rely on validators in order for a single transaction to be conducted. But the fraud proof tries to eliminate all these trust issues by allowing its mechanisms to conduct any malicious behavior or incorrect matters that are conducted by validators. Then ensures that trust issues are reduced.&nbsp;</p> 
<h3 class="wp-block-heading" id="strong-conclusion-strong"><strong>Conclusion</strong></h3> 
<p><a href="https://www.thecoinrepublic.com/2023/09/24/chainlink-taps-eth-layer-2-protocol-for-cross-chain-development/" rel="noopener noreferrer nofollow">Securing layer 2</a> is the objective of both fraud proof and verifiers. For instance the verifiers conduct a secure transaction by following a certain sequence on how these information were received. Its importance is clearly one of the ways to secure layer 2, providing trustless transactions and information to be corresponding in case these validations are to be made. This provides security in layer 2.&nbsp;</p> 
<p>Combine the interactive and non-interactive technique to provide security to layer 2. The double checking of assertion to provide a correct assertion which secures layer 2 with a vast amount of assertion.&nbsp;</p>
