III. Spectra Chain Architecture

III. Spectra Chain Architecture

  • Layer 2 (Spectra Chain) Integration:

  • Layer 2 (Spectra Chain) Integration:

Spectra Chain operates as a Layer 2 solution, enhancing interoperability and facilitating seamless transactions within the blockchain ecosystem. It bridges the gap between the Bitcoin network and decentralized applications (dApps), leveraging advanced rollup technology to ensure efficient and secure asset transfer.

  • Sequencers and Transaction Sequencing:

  • Sequencers and Transaction Sequencing:

At the heart of Spectra Chain's architecture lies the sequencing layer, powered by execution nodes responsible for orchestrating transaction flow. These nodes prioritize and process transactions, preparing them for incorporation into Layer 2 blocks. Sequencers play a pivotal role in aggregating transactions, employing rollup technology to consolidate data and maintain transparency across the network. Their function extends to validating transactions, ensuring their integrity before they are finalized on the foundational settlement layer.

  • Cryptographic Proof Generation:

  • Cryptographic Proof Generation:

A critical component of Spectra Chain’s infrastructure is the cryptographic proof system, which involves a network of provers tasked with generating and verifying proofs of transaction validity. This layer ensures the accuracy and legitimacy of all transactions processed on Spectra Chain, reinforcing the platform’s commitment to security and trustworthiness.

  • Settlement Layer (Layer 1) Integration:

  • Settlement Layer (Layer 1) Integration:

The settlement layer forms the backbone of Spectra Chain's architecture, utilizing Bitcoin as the primary ledger for final transaction settlement. This layer employs bridges and specialized scripts to embed Layer 2 transaction data within the Bitcoin blockchain, securing the finality and immutability of transactions.

IV. Rollup Protocol Implementation Overview

IV. Rollup Protocol Implementation Overview

The foundational element enabling the Spectra chain's operational framework is the Zero-Knowledge Rollup (ZK Rollup) construct. This section provides a granular overview of the ZK Rollup mechanism, emphasizing its integral role in the Spectra chain architecture. We explore the rationale behind selecting ZK Rollup as the cornerstone for the Spectra chain, aligning with our comprehensive design objectives.

Layer 2 Block Storage Mechanisms

Layer 2 Block Storage Mechanisms

Within the Spectra chain ecosystem, Layer 2 (L2) blocks are efficiently archived on the Bitcoin blockchain, ensuring minimal Layer 1 transactional costs. These blocks are encapsulated within Bitcoin transactions and, upon inclusion in sufficiently proven blocks, the transactional data becomes immutable, thus inheriting the robust availability and integrity assurances of the Bitcoin network.

Zero-Knowledge Rollups

Zero-Knowledge Rollups

The Spectra chain is instantiated as a Zero-Knowledge (ZK) Rollup, a model that leverages an external "parent" blockchain's consensus protocol (e.g., Proof of Work or Proof of Stake) for its security paradigms, eschewing the need for an indigenous consensus framework. Specifically, the Spectra chain's primary network is anchored to the Bitcoin blockchain as its parent.

Block Generation

Block Generation

Spectra chain blocks are primarily produced and managed by a party called the "sequencer," which assists the Spectra chain Layer 2 network by:

  • Facilitating Transaction Confirmations and State Modifications: This involves the process of validating transaction completions and updating the system state accordingly to reflect the latest changes within the network.

  • Execution of Layer 2 (L2) Blocks: compilation of transactions into blocks at the second layer (L2) and executing these blocks to process and finalize transactions within the L2 infrastructure.

  • Transmission of User Transactions to Layer 1 (L1) for Settlement: involves the forwarding of transactions initiated by users from the Layer 2 environment to the primary Layer 1 blockchain, ensuring the final settlement and integration of these transactions into the L1 Ledger.

The 2 Sequencer Transaction Pathways:

The 2 Sequencer Transaction Pathways:

  1. Within the Spectra chain architecture, the sequencing mechanism incorporates a transaction pool (mempool), analogous to the mempool present in Bitcoin's Layer 1 (L1) protocol. However, this mempool is designated as private, a strategic measure aimed at mitigating the potential for Miner Extractable Value (MEV) exploitation. On the Spectra chain's primary network, block generation occurs at intervals ranging from 3 to 10 seconds—the precise cadence remains subject to finalization. These blocks may be instantiated devoid of transactions, reach their maximum transaction capacity as dictated by the block's gas limit, or encapsulate a transaction volume that falls within this spectrum.

  1. Transactions submitted directly to the sequencer. The cost of submitting these transactions is much lower than L1 (as there is no separate L1 transaction fee), but the sequencer is the only entity aware of these transactions, making them non-resistant to censorship.

Initially, the Spectra chain Foundation is the sole block producer on the Spectra chain mainnet, but it will gradually transition to a decentralized sequencer network.

Block Execution

Block Execution

The block execution mechanism within the system employs a dual-faceted approach to receive and process blocks:

  1. The execution engine is capable of self-updating through a decentralized peer-to-peer (P2P) network. This method mirrors the synchronization process utilized by Layer 1 (L1) execution clients, which ensures state consistency across the distributed network.

  1. The system incorporates Rollup nodes, realized as Spectra-Node elements, which extract Layer 2 (L2) blocks directly from the underlying Layer 1 data. Although this approach may exhibit increased latency, it offers a significant advantage in terms of resilience against censorship efforts.
