EpiK Decentralized Knowledge Graph Platform: Architecture, Challenges, and Participation
The article explains how EpiK uses blockchain‑based storage, incentive mechanisms, and DAO governance to build a decentralized, open‑source knowledge‑graph platform that addresses AI data needs, coordination challenges, and encourages participation from experts, miners, and bounty hunters.
On January 10, EpiK organized the "2021 Open Source Knowledge Movement" bringing together experts from Tsinghua University, the Chinese Computer Society Knowledge Graph SIG, and Northeastern University to discuss open and interconnected knowledge graphs.
Why build a decentralized knowledge‑graph collaboration platform? In the AI era, knowledge graphs are essential for machine understanding, but large‑scale construction requires high‑quality data from many domains and faces trust, duplication, and coordination challenges.
Key challenges include organizing contributors, ensuring trustworthy and immutable storage, and providing incentives that align individual interests with collective benefit.
EpiK addresses these challenges with three blockchain‑based components: Storage, Incentives, and DAO governance.
Storage : built on the IPFS protocol and enhanced with FileCoin’s Proof‑of‑Replication (PoRep) and Proof‑of‑Spacetime (PoSt) to prevent witch attacks and guarantee data immutability; a blockchain ledger records file creation order and operation logs, ensuring consistent knowledge‑graph databases across more than 9,000 registered nodes.
Incentives : defines three contributor roles—data miners, domain experts, and bounty hunters—plus data gateways; daily token rewards are allocated (75% to miners, 9% to experts, 15% to bounty hunters) based on storage contribution, data quality, and task completion, with staking mechanisms to secure participation.
DAO : multiple DAOs (EpiK DAO for global parameters, Experts DAO for expert reward formulas, Miners DAO for storage settings) govern the system via smart contracts, enabling automated, trustless management of the knowledge‑graph ecosystem.
The platform invites participation from industry experts (who upload and verify data), bounty hunters (who perform annotation tasks), and storage miners (who provide space and bandwidth), each receiving token compensation aligned with their contributions.
The article concludes that EpiK’s decentralized knowledge‑graph platform, powered by blockchain, will become a foundational infrastructure for future AI applications, driving continuous data value upgrades.
