Architecture Overview

DAPP Service Providers run the DAPP Network services

DAPP Service nodes provide the API endpoint for users to request services. So for example, in the case of a LiquidHarmony oracle request, the developer would direct that transaction to the DSP API's endpoint, and not a normal nodeos RPC endpoint.

A DSP must run:

  • nodeos instance (eosio blockchain node)

  • IPFS node (file storage for vRAM and LiquidStorage)

  • PostgreSQL database to monitor service requests

  • Public API Endpoint to interact with services

A DSP may also optionally run

  • dfuse API node provides dfuse's push guarantee and uses dfuse's web socket versus demux

  • go-ethereum RPC node for LiquidLink's EVM signing service
