Sharding

Definition

Sharding is a scaling technique that splits a blockchain into multiple parallel chains (shards), each processing transactions independently. This horizontal scaling approach increases transaction throughput by allowing parallel processing across multiple shards.

Core Properties

Horizontal Scaling

  • Parallel processing: Multiple shards process transactions simultaneously
  • Independent shards: Each shard operates independently
  • Cross-shard communication: Transactions between different shards
  • Shard coordination: Coordination between shards
  • Load distribution: Distributing load across shards

Shard Management

  • Shard assignment: Assigning transactions to shards
  • Shard rotation: Rotating validators between shards
  • Shard synchronization: Synchronizing shard states
  • Shard security: Securing individual shards
  • Shard governance: Governing shard operations

Technical Implementation

Shard Structure

Shard = (Shard ID, Validators, Transactions, State)
Cross-Shard Transaction = (From Shard, To Shard, Data)
Shard Coordination = (Shard State, Cross-Shard Communication)
