Dual-Ledger Architecture

Key Takeaways

  • • Block-lattice provides individual account chains for parallel transaction processing
  • • Meta-DAG layer handles consensus and provides global ordering
  • • Plasma system enables feeless transactions through QSR fusion
  • • Network of Momentum consensus achieves security without energy waste

The Block-Lattice Foundation

At the base layer, Zenon uses a block-lattice structure where each account has its own blockchain. When you send tokens, you create a "send" block on your chain, and the recipient creates a "receive" block on theirs. This separation means transactions can be processed in parallel — your transaction does not wait in line behind everyone else's.

This design eliminates the global bottleneck found in traditional blockchains like Ethereum, where every transaction competes for space in the next block. Instead, the network can process thousands of transactions simultaneously across different account chains.

The Meta-DAG Consensus Layer

While the block-lattice handles individual transactions, the meta-DAG (Directed Acyclic Graph) provides global consensus. Pillars — the network's validator nodes — create momentum blocks that reference and confirm transactions from the block-lattice layer. This creates a hierarchical structure where:

  • Account chains handle user transactions asynchronously
  • Momentum blocks provide checkpoints and ordering
  • The DAG structure allows for efficient consensus without bottlenecks

Plasma: The Feeless Engine

Plasma is Zenon's solution to transaction fees. Instead of paying per transaction, users generate Plasma by:

  • Fusing QSR: Lock your QSR tokens to generate Plasma over time. The more QSR fused, the more Plasma you generate.
  • Proof-of-Work: For users without QSR, a small computational puzzle can generate enough Plasma for basic transactions.

This dual approach ensures the network remains accessible to everyone while rewarding long-term participants who stake their QSR.

Network of Momentum Consensus

The consensus mechanism combines elements of delegated proof-of-stake with the unique dual-ledger structure. Pillars must stake 15,000 ZNN to participate in consensus, and they are selected to produce momentum blocks based on their weight and voting history. This creates a system that is:

  • Energy efficient: No mining required
  • Decentralized: Anyone can run a Pillar with sufficient stake
  • Secure: Economic incentives align validators with network health
  • Fast: Momentum blocks are produced every ~10 seconds

Why This Design?

Most blockchains force a tradeoff: fast and cheap, or secure and decentralized. Zenon's dual-ledger architecture attempts to break this trilemma by separating concerns. The block-lattice handles throughput, the meta-DAG handles security, and Plasma handles accessibility. Each component is optimized for its specific role rather than trying to do everything in one layer.
