Rollup

Zero-Knowledge Rollups (ZK Rollups): At the core of Spectra Chain's operational framework is the ZK Rollup construct, chosen for its ability to enhance scalability, security, and efficiency within the blockchain ecosystem. This technology is pivotal in ensuring minimal transaction costs and leveraging Bitcoin's network for the immutable storage of Layer 2 (L2) blocks.

Layer 2 Block Storage: L2 blocks are securely archived on the Bitcoin blockchain, encapsulated within Bitcoin transactions to utilize the network's security and integrity, significantly reducing Layer 1 transactional costs.

Operational Mechanics:

• Block Generation and Sequencer Role: The "sequencer" plays a crucial role in managing Spectra Chain blocks, facilitating transaction confirmations, and executing L2 blocks to finalize transactions. This includes managing a private transaction pool to mitigate Miner Extractable Value (MEV) exploitation and ensuring the seamless transmission of user transactions to the primary Layer 1 blockchain for settlement.

• Sequencer Transaction Pathways: The sequencer operates with dual pathways for transactions; one via a private mempool for reduced costs and enhanced privacy, and another for direct submissions to ensure lower L1 fees, fostering a non-resistant approach to censorship.

Block Execution Strategy: A decentralized peer-to-peer (P2P) network supports the self-updating execution engine, mirroring Layer 1 synchronization processes for consistent state across the network. Additionally, Rollup nodes, acting as Spectra-Nodes, extract L2 block data directly from L1, balancing increased latency with enhanced censorship resistance.
