Stores Overview

Introduction

Yaci Store is built on a modular architecture where different types of blockchain data are organized into separate modules called "stores". This design provides flexibility, scalability, and allows users to enable only the functionality they need.

Architecture Overview

Core Principles

  1. Modularity: Each store is independent and can be enabled/disabled based on requirements
  2. Event-Driven: Stores react to blockchain events (blocks, transactions, etc.) published by the sync engine
  3. Parallel Processing: Core stores process data in parallel for optimal performance
  4. Extensibility: Plugin framework allows customization without modifying core code

Data Flow

Cardano Node → Sync → Event Publisher →  Processors →  Storage implementations → Database
                                             ↓                         ↓

Store Categories

Core Stores

These stores handle fundamental blockchain data and are enabled by default:

  • Assets Store: Manages native tokens, NFTs, and fungible tokens
  • Blocks Store: Stores block-related information
  • Epoch Store: Tracks epoch parameters, and epoch-specific data
  • Governance Store: Handles governance actions, proposals, votes, and DRep data
  • Metadata Store: Stores transaction metadata
  • MIR Store: Processes Move Instantaneous Rewards certificates
  • Script Store: Manages Plutus scripts, native scripts, and script references
  • Staking Store: Tracks stake pools, delegations, registrations, and rewards
  • Transaction Store: Stores transaction data
  • UTxO Store: Manages unspent transaction outputs and spending relationships

Aggregation Modules

These modules perform complex calculations and are disabled by default:

  • Account: Calculates and maintains address balances over time
  • Adapot: Tracks ADA distribution across different pots (treasury, reserves, etc.) and calculate rewards
  • Governance Aggregation: Calculate governance-related state
  • Epoch Aggregation: Aggregates epoch level data
