Implementation Highlights
Optimistic Rollup Using OP Stack: X employs an Optimistic Rollup solution built on the OP Stack to enhance transaction throughput and reduce costs while maintaining security.
Mechanism: Transactions are processed off-chain, assuming they are valid by default. Periodic proofs are submitted to the Ethereum mainnet to ensure the integrity and validity of transactions.
Benefits: This approach significantly increases transaction speeds and reduces costs, making financial services more accessible and efficient.
Custom Gas Token (xUSD) Implementation: xUSD, a USD-pegged stablecoin, is used as the native gas token within the Layer 2 network.
Purpose: Using xUSD for transaction fees simplifies the user experience by eliminating the need for multiple cryptocurrencies and providing a stable and predictable cost structure.
Integration: xUSD is directly integrated into the modified Ethereum Virtual Machine (EVM) within the OP Stack, ensuring seamless transactions and consistent gas pricing.
Blockchain Explorer Integration (BlockScout): BlockScout, an open-source blockchain explorer, is customized to provide comprehensive visibility into the X Layer 2 network.
Customization: BlockScout is tailored to support xUSD transactions, offering real-time views of blocks, transactions, balances, and token activities.
Features: Advanced querying capabilities and analytics enhance transparency and allow users to track their transactions and activities with ease.
