Blockchain Architecture ​

Overview ​

QuStream is a Layer 1 blockchain built with scalability, security, and quantum resistance at its core. Unlike traditional blockchains that rely on vulnerable cryptographic primitives, QuStream integrates post-quantum encryption directly into its architecture.

Key Components ​

1️⃣ Dual-Network Node Structure ​

QuStream operates with a dual-node system, separating transaction validation and encryption processing:

  • Validator Nodes handle consensus, smart contracts, and transaction finalization.
  • Encryption Nodes process quantum-safe key generation and sharded data storage.

2️⃣ Proof-of-Stake (PoS) Consensus ​

QuStream secures its network using delegated Proof-of-Stake (dPoS), allowing:

  • Efficient transaction processing with high throughput.
  • Reduced energy consumption compared to Proof-of-Work (PoW) blockchains.
  • Decentralized governance where token holders participate in staking and network security.

3️⃣ Vertical Sharding for Data Storage ​

QuStream enhances data security and scalability using vertical sharding, ensuring:

  • Encryption data is split between QuStream-run and community-run nodes.
  • Even if an attacker compromises a node, they never have full access to the data.
  • Load balancing across nodes, reducing storage congestion.

4️⃣ Built-In Quantum-Safe Encryption ​

Unlike traditional blockchains that rely on static key cryptography, QuStream uses:

  • Dynamic key generation for transactions and data encryption.
  • Mathematically proven 504-bit quantum hardness to resist attacks.
  • Sharded encryption nodes to distribute key storage securely.

Scalability & Network Performance ​

QuStream is designed for high transaction speeds and network efficiency:

  • Transaction finality within seconds using PoS consensus.
  • Parallel processing through vertical sharding.
  • Load balancing across Validator & Encryption Nodes.

Conclusion ​

QuStream’s blockchain architecture is built for longevity, security, and real-world adoption. By integrating quantum-safe encryption, sharded storage, and PoS consensus, it provides a robust foundation for Web3 applications, enterprises, and financial institutions.
