Sidechains

Definition

Sidechains are independent blockchains that are connected to a main blockchain (parent chain) through a two-way bridge, allowing assets to be transferred between chains. They provide scalability and customization while maintaining security through the parent chain.

Core Properties

Independent Operation

  • Separate consensus: Own consensus mechanism
  • Independent governance: Own governance system
  • Customization: Optimized for specific use cases
  • Scalability: Higher transaction throughput
  • Flexibility: Flexible design and implementation

Bridge Connections

  • Two-way bridge: Transfer assets between chains
  • Asset locking: Locking assets on parent chain
  • Asset minting: Minting assets on sidechain
  • Asset burning: Burning assets on sidechain
  • Asset unlocking: Unlocking assets on parent chain

Beneficial Potentials

Scalability and Performance

  • High throughput: Higher transaction throughput
  • Low latency: Faster transaction confirmation
  • Low costs: Lower transaction fees
  • Scalability: Better scalability than main chain
  • Efficiency: More efficient transaction processing

Customization and Innovation

  • Custom consensus: Custom consensus mechanisms
  • Custom governance: Custom governance systems
  • Custom features: Custom features and functionality
  • Innovation: Innovation in blockchain design
