The main aim of ragno network(other than providing data to dojima cross-chain protocol) is to power data for several protocols in a fast, efficient and decentralised manner.

​
Crawler

  • The crawler node is responsible for fetching and filtering data from multiple blockchains, specifically focusing on identifying Dojima cross-chain transactions.
  • It operates in conjunction with a Hermes node, connected via a secure bridge. This enables a secure and optimized way to transfer filtered transactions to the Dojima cross-chain protocol.
  • The crawler node interacts with the network by accessing data from operator gateway servers, ensuring decentralization and efficiency.

​
Operator

  • Operators are essential participants in the Ragno Network. They host nodes from blockchains of their choice as part of the decentralized infrastructure.
  • Operators must stake a minimum number of $DOJ tokens to become part of the network.
  • They are rewarded in $DOJ tokens based on their contributions, particularly the data they provide to the Dojima cross-chain protocol.

​
Operator dashboard

  • The Operator Dashboard is a critical tool that enables operators to manage their nodes and monitor their performance.
  • Key functionalities include:
    • Registering new nodes.
    • Monitoring node health and performance metrics.
    • Tracking rewards earned through participation in the network.
  • Operators can securely log in using their private keys and import nodes hosted elsewhere to earn additional rewards by contributing to the Dojima cross-chain protocol.

​
Operator gateway server

  • Once an operator becomes part of the network by staking, an operator gateway server is automatically set up.
  • This gateway server acts as a secure intermediary between the operator’s nodes and the crawler nodes.
  • Key functionalities of the gateway server include:
    • Authenticating requests from crawler nodes to fetch block data.
    • Verifying signatures and mapping public keys with pairing lists.
    • Rate limiting, authentication, and caching to ensure efficient and fair access to the data.
  • The gateway server provides a reliable mechanism for operators to control access to their node resources while still contributing data to the Ragno Network.

​
Working of the above setup

  • Hermes Chain manages the identities and operations of all actors (operators and crawlers) within the cross-chain protocol.
  • Operators register their nodes on the Hermes chain, while crawler nodes interact with the operators to fetch necessary data from the blockchains.
  • Every 200 blocks, Hermes maps crawlers to operators using a Pairing List (PL):
    • Each crawler submits a PL, which is aggregated and finalized by Hermes.
    • The final PL is fetched by the crawlers, who can then request block data from the assigned operator servers.
  • Data Flow:
    • Crawlers can only request data from operators they are mapped to via the PL.
    • Once crawlers fetch the data, they filter for Dojima cross-chain transactions.
    • These filtered transactions are batched and sent back to the Hermes chain for further processing.
  • Rewards: Operators claim their rewards for providing data, with the reward amount calculated based on the compute units they contribute to the network.
