Verify Off-chain Results and Whitelist With ECDSA in Solidity Using OpenZeppelin and Ethers.js

Verify Off-chain Results and Whitelist With ECDSA in Solidity Using OpenZeppelin and Ethers.js

Offloading expensive computation to off-chain for saving gas, as simple & fast as possiblePhoto by Shubham Dhage on Unsplash, more artworks at http://guerrillabuzz.com/ Table of Contents i. Introductionii. Practical exampleiii. Conclusion Introduction Ethereum’s high gas problem should not be unfamiliar to you, as a crypto trader, a blockchain developer, or just an enthusiast in the space. With Ether's price standing strong in the $3000 area and gas price on the rise averaging 50–70 Gwei, the gas fee for every transaction is getting more expensive and takes about $4 USD for a simple transfer. There is a way to go around the gas problem, is to put this computation off-chain and let the server do the work. A lot of tutorials online teaching ECDSA involves the use of maths, something about s, r, v, which we all developers (code monkeys) can agree, is boring and difficult to implement without bugs. So in this article, we are just gonna use the built-in functions from contracts written by OpenZeppelin and Ethers.js to build this feature. Practical example In this project, we are going to use a common use case for ECDSA to demonstrate the method, which is setting up a whitelist for an NFT project, and include code snippets to help you get started. This project is written in JavaScript and Solidity.

  1. Setup To prepare for ECDSA, you should create a new wallet and use it only for this project as the signature signer. Do not use this wallet for any other purpose but only for signing the message in this project. After creating the wallet, save its private key for later use.
  2. Off-chain Signature 2.1. To get started, we will need to first install Ether.js by running: npm run ethers and importing it into the project by: import ethers from ethers 2.2. Then we can initialize the signer instance by creating a new Wallet using the library: const signer = new ethers.Wallet("0x" + "<your private key>"); Remember to add 0x in the prefix of your private key if you exported directly from Metamask. 2.3. Pack the message together, and we can try to pack the address and the nonce for whitelisting: let message = ethers.utils.solidityPack(["address", "uint256"], ["0xabc", "0"]); This is to concatenate the message together to be hashed in the next section. Ethers.js supports a wide range of variables, including string and array like uint256[]: 2.4. Hash the message with keccak256 and sign with the signer wallet: message = ethers.utils.solidityKeccak256(["bytes"], [message]);const signature = await signer.signMessage(ethers.utils.arrayify(message)); This signature is the signature signed for the message with the signer's private key. We can pass this signature along with the verified parameters into the blockchain to ensure that the parameters are valid. The whole code snippet:https://medium.com/media/b7bf0931c9291dc5ff9d222c2f8a4753/href
  3. On-chain Verification 3.1. To verify the signature on-chain, we can make use of the contract EDCSA written by OpenZeppelin. To use it, install Openzepplin locally or use it in Remix: npm install @openzeppelin/contracts 3.2. Set up the storage for signer on-chain with a setter: address signer; function setSigner(address _signer) external { signer = _signer;} 3.3. Then pack the values together by abi.encodePacked and hash it with keccack256: bytes32 hash = keccak256(abi.encodePacked(msg.sender, nonce)); 3.4. Turn the signature to an Ethereum signed message: bytes32 message = ECDSA.toEthSignedMessageHash(hash); 3.5. Recover the signer address from the signature: address receivedAddress = ECDSA.recover(message, signature); 3.6. Check if the signer of the message matches the signer store on-chain, only approve if the signer matches: require(receivedAddress != address(0) && receivedAddress == signer); The whole code snippet is:https://medium.com/media/9d470e1a4f48d90b838f2c876555677c/href Conclusion And now you learned how to use ECDSA as simply as possible, without the use of any complex maths. However, there are also tradeoffs of putting computation off-chain but that is beyond the scope of this article. I am going to explain more on this so follow to stay tuned! Want to Connect?

Best Crypto To Invest In: Pepeto vs BlockDAG, Layer Brett, Remittix, Little Pepe

The post Best Crypto To Invest In: Pepeto vs BlockDAG, Layer Brett, Remittix, Little Pepe appeared on BitcoinEthereumNews.com. Searching for the best crypto presale of 2025? Five names lead the chatter: Pepeto, BlockDAG, Layer Brett, Remittix, and Little Pepe. This quick comparison cuts the hype and focuses on what matters, what’s live now, what’s audited, how clear the tokenomics are, and where real utility shows. We highlight DEX/bridge delivery, Layer-2 claims, PayFi rails, staking, and listings so searches like “best crypto to buy now” land on facts, helping you choose based on evidence rather than guesswork. Want to see who actually delivers today, and who deserves to be called the best crypto to buy now? Read on. Pepeto on Ethereum: Zero-Fee DEX and Cross-Chain Bridge Live  In a crowded market of crypto presales, Pepeto delivers real tools on Ethereum mainnet: PepetoSwap, a fast zero-fee DEX, and Pepeto Bridge for smooth cross-chain moves. The crypto presale is priced at $0.000000152 and has raised $6.6M+ so far, with whales taking positions ahead of the next stage; staking near 231% APY keeps funds active as liquidity builds. A 420T total supply sets clear tokenomics for liquidity, listings, marketing, and staking, while a live demo exchange, shown on an official X post, signals delivery today and a shorter path from traction to scale. Backed by a 100,000+ community and rising Tier-1 chatter as builders engage and demand expands, momentum points to a strong launch once trading begins; check the project’s official materials and latest build notes for full details. Blockdag: Marketing vs. Verification: Transparency and On-Chain Proof Before chasing the next big token, separate what’s shipped from what’s promised. BlockDAG (BDAG) claims “10x upside,” but slogans don’t equal lasting value. Following the BDAG Deployment Event and a pricing reset to $0.0013, the bigger concern is transparency: there’s limited independently verifiable on-chain proof for key metrics, unclear exchange-ready liquidity plans and post-listing unlocks,…

ZK-Rollup: The Future of Blockchain Scalability

ZK-Rollup: The Future of Blockchain Scalability

ZK-Rollup: The Future of Blockchain Scalability Blockchain technology has evolved rapidly over the past decade, reshaping industries with decentralized finance (DeFi), NFTs, and Web3 applications. Yet, one of the most significant challenges remains: scalability. Networks like Ethereum are powerful but often suffer from congestion, high transaction fees, and slower processing times. This is where Layer 2 solutions come in — and among them, ZK-Rollups (Zero-Knowledge Rollups) stand out as a promising path forward. By leveraging zero-knowledge proofs to validate transactions, ZK-Rollups enable blockchains to process thousands of transactions efficiently, securely, and at a fraction of the cost. In this article, we’ll explore what ZK-Rollups are, how they work, their benefits, real-world use cases, challenges, and why they represent the future of blockchain scalability. What Is a ZK-Rollup? A ZK-Rollup is a Layer 2 scaling solution that bundles hundreds or thousands of off-chain transactions into a single batch. Instead of submitting each transaction individually to the main blockchain (Layer 1), ZK-Rollups generate a validity proof — using zero-knowledge cryptography — that verifies the correctness of all transactions in the batch. This proof is then published to the main chain, significantly reducing data load while maintaining Ethereum-level security. Key features: Batch Processing — Multiple transactions grouped together. Validity Proofs — Mathematical evidence that all transactions are valid. On-Chain Verification — Ethereum only verifies the proof, not each transaction. Efficiency — Low gas fees, high throughput, and secure settlement. How Do ZK-Rollups Work? Step 1: Off-Chain Transaction ExecutionTransactions are first processed off-chain in a Layer 2 environment. Users interact with smart contracts, send tokens, or perform trades without overwhelming the Layer 1 blockchain. Step 2: AggregationThese off-chain transactions are collected into batches by a Rollup operator (sometimes called a “sequencer”). Step 3: Zero-Knowledge Proof GenerationOperators generate a SNARK or STARK proof for each batch, confirming through zero-knowledge methods that all bundled transactions are valid. Step 4: Proof SubmissionThe validity proof is submitted to the Ethereum mainnet. Instead of validating each transaction, Ethereum only validates the proof. Step 5: On-Chain FinalityOnce Ethereum verifies the proof, all transactions in the batch are finalized with the same security guarantees as if they were executed directly on-chain. Why ZK-Rollups Matter for Blockchain Scalability Blockchain networks like Ethereum have limited capacity — processing only about 15 transactions per second (TPS). In times of high demand, gas fees can skyrocket, making blockchain use impractical for everyday applications. ZK-Rollups address this by: Increasing throughput to thousands of TPS. Cutting down transaction costs. Providing instant finality (no long waiting periods). Maintaining Ethereum’s strong security model. For Web3 to scale to millions of users, solutions like ZK-Rollups are not optional — they’re essential. Benefits of ZK-Rollups

  1. Scalability at ScaleZK-Rollups can process thousands of transactions in a single proof. This means more users can interact with blockchain applications without causing congestion.
  2. Lower Transaction CostsSince many transactions are bundled, gas costs are distributed among users, drastically reducing fees. For example, sending tokens on zkSync or Loopring costs a fraction of Ethereum’s fees.
  3. Enhanced SecurityUnlike sidechains or other off-chain solutions, ZK-Rollups inherit Ethereum’s Layer 1 security. Even if the Rollup operator acts maliciously, the validity proofs ensure that only valid transactions are finalized.
  4. Instant FinalityOptimistic Rollups require a waiting period (fraud-proof challenge window) to finalize transactions. In contrast, ZK-Rollups finalize transactions immediately after Ethereum verifies the proof, making them ideal for high-frequency applications.
  5. Reduced Data Storage on L1Only proofs and minimal transaction data are stored on Ethereum, significantly reducing blockchain bloat while ensuring data availability. Both are vital Layer 2 solutions, but ZK-Rollups are generally more efficient — though technically more complex to implement. Use Cases of ZK-Rollups PaymentsPlatforms like zkSync allow fast, cheap token transfers, enabling everyday blockchain payments. Decentralized Exchanges (DEXs)Loopring uses ZK-Rollups to provide secure, low-cost, high-speed trading experiences. NFT Minting and TransfersMinting NFTs on ZK-Rollups drastically reduces gas fees, making it more affordable for creators. DeFi ProtocolsLending, borrowing, and yield farming can scale efficiently on ZK-Rollups with lower transaction costs. Gaming and Metaverse Games can handle thousands of microtransactions with minimal costs, improving user experience. Popular ZK-Rollup Projects zkSync — A Layer 2 scaling solution focused on payments and smart contracts. Loopring — A protocol that leverages ZK-Rollups for efficient DEX trading. StarkNet — Uses STARK proofs to deliver scalable, general-purpose computation. Polygon zkEVM — Brings Ethereum Virtual Machine (EVM) compatibility to ZK-Rollups. Aztec — Focused on privacy-preserving transactions with ZK-Rollups. ZK-Rollups prove to be highly versatile, as shown by these projects across multiple sectors. Challenges of ZK-Rollups Despite their promise, ZK-Rollups face hurdles: Technical Complexity — Building and implementing zero-knowledge proofs require advanced cryptography and computing power. High Development Costs — The infrastructure for ZK-Rollups is resource-intensive. Ecosystem Maturity — Not all tools and dApps fully support ZK-Rollup environments yet. Data Availability — Ensuring all users can access off-chain data remains a critical issue. Centralization Risks — Some ZK-Rollup projects rely on centralized operators, raising concerns until decentralization improves. The Future of ZK-Rollups The next phase of blockchain adoption depends heavily on scalability. As Ethereum transitions with upgrades like Danksharding and Proto-Danksharding (EIP-4844), ZK-Rollups will integrate more seamlessly into the ecosystem. Trends to watch: Widespread EVM compatibility — Making it easy for developers to deploy Ethereum smart contracts on ZK-Rollups.Privacy Enhancements — Combining zero-knowledge proofs with privacy-preserving features.Cross-Chain Rollups — Interoperability between different blockchains using ZK-proofs.Mainstream Adoption — Payments, supply chain, healthcare, and fintech adopting ZK-Rollup solutions. Why ZK-Rollups Represent the Future of Blockchain Scalability Unmatched Efficiency — High throughput and low fees.Ethereum-Level Security — Without sacrificing decentralization.Instant Finality — Faster transactions than other Layer 2 models.Versatile Use Cases — From DeFi to NFTs to gaming.Future-Proof Technology — Aligns with Ethereum’s scaling roadmap. Simply put, ZK-Rollups offer the best combination of scalability, security, and efficiency, making them the backbone of blockchain’s next growth phase. Conclusion Scalability has always been blockchain’s biggest challenge. While Layer 1 upgrades like Ethereum 2.0 are important, Layer 2 solutions — especially ZK-Rollups — are leading the charge in making blockchains fast, affordable, and accessible for mass adoption. From payments and DeFi to NFTs and gaming, ZK-Rollups are unlocking a new era of possibilities. With projects like zkSync, StarkNet, and Polygon zkEVM paving the way, it’s clear that ZK-Rollups are not just a temporary fix — they are the future of blockchain scalability. For businesses, developers, and users alike, embracing ZK-Rollups means stepping into a faster, fairer, and more secure decentralized future.
