Pooler Intro

Overview

Pooler is the component of a fully functional, distributed system that works alongside Audit Protocol and together they are responsible for

• generating a time series database of changes occuring over smart contract state data and event logs, that live on decentralized storage protocols
• higher order aggregated information calculated over decentralized indexes maintained atop the database mentioned above

Pooler by itself, performs the following functions:

1. Tracks the blockchain on which the data source smart contract lives
2. In equally spaced 'epochs'
   • it snapshots raw smart contract state variables, event logs etc
   • transforms the same
   • and submits these snapshots to audit-protocol

This specific implementation is called Pooler since it tracks Uniswap v2 'pools'.

Together with an Audit Protocol instance, they form a recently released PoC whose objectives were

• to present a fully functional, distributed system comprised of lightweight services that can be deployed over multiple instances on a network or even on a single instance
• to be able to serve most frequently sought data points on Uniswap v2
  • Total Value Locked (TVL)
  • Trade Volume, token reserves, Fees earned
    • grouped by
      • Pair contracts
      • Individual tokens participating in pair contract
    • aggregated over time periods
      • 24 hours
      • 7 days
  • Transactions containing Swap , Mint , Burn events
