• NFT Marketplaces: zkSync makes minting, buying, and selling NFTs more cost-effective, fostering greater participation in the NFT space.

Social and Infrastructure

• On-chain Social Platforms: zkSync supports gasless transactions, making it suitable for social media platforms that require frequent state updates.
• Cross-chain Bridges: zkSync enables fast and secure cross-chain transactions, facilitating interoperability between different blockchain networks.
• Indexing Solutions: zkSync's high scalability and efficiency make it ideal for indexing solutions that require processing large amounts of data.

Consumer Applications

• Subscription Services: zkSync's paymaster system allows for subscription-based models where users can pay in tokens other than ETH.
• Content Monetization Platforms: zkSync enables cost-effective and efficient content monetization, making it suitable for platforms that require frequent microtransactions.

Developer Tools

• Paymaster Implementation Frameworks: zkSync provides frameworks for implementing paymaster functionality, making it easier for developers to create user-friendly applications.
• Development Environments and Testing Tools: zkSync supports a range of development tools and testing environments, facilitating the development of scalable and efficient applications.

Pros of zkSync

• Low Gas Fees: zkSync offers up to 100 times cheaper gas fees compared to Layer-1 solutions, making it more cost-effective for users.
• Increased Transaction Speed: zkSync features high transaction speeds, with capabilities of up to 20,000 transactions per second (tps) and plans for even higher throughput with future updates.
• Improved Security: zkSync provides security that is on par with Layer-1 blockchains, ensuring a secure environment for transactions.
• Easy Transfers & Withdrawals: zkSync allows for smooth asset transactions between Layer-1 and Layer-2 blockchains, with assets available for withdrawal at any time.
• EVM Compatibility: zkSync supports EVM (Ethereum Virtual Machine) compatibility, enabling the execution of smart contracts and enhancing interoperability.
• Gasless Meta-Transactions: Users can pay gas fees in transferred tokens, not just ETH, making transactions more flexible.
• Atomic Swaps and Limit Orders: zkSync supports atomic swaps and limit orders, which are crucial for crypto exchanges.

Cons of zkSync

• Slow Withdrawal Speeds: Some users report slow speeds when withdrawing funds back to the Layer-1 protocol, as they have to wait for other transactions to be finalized in a single batch.
• High Computational Power: Proving every batch requires relatively high computational power, which can limit the development of dApps.
• EVM Compatibility Issues: The general EVM is still evolving, which can cause issues for the zkSync network, including synchronization problems with wallets and exchange platforms.
• Transaction Processing Problems: There are risks of transaction loss if major wallets and exchange platforms aren’t synchronized with Layer-2 networks.
• Limited dApp Support: The high computational power required for proving batches can make dApps less common in ZK rollups compared to Optimistic rollups.
• Token Mapping Problems: Tokens issued on zkSync and the ETH mainnet require manual management of their mapping relationship, which can be complex.
