Quai Network primary sources

Reviewed: 2026-05-14 UTC

Official site

  • https://qu.ai/
    • Best concise top-level framing of Quai’s architecture and product claims.
    • Used to confirm the Prime / Region / Zone hierarchy, merged-mined shared security, PoEM positioning, the dual-token QUAI + QI monetary design, and the project’s explicit 50,000+ TPS / low-fee framing.
    • Also useful because it makes clear that Quai wants to be understood not just as a fast chain but as a full monetary system with one EVM token and one UTXO-style token.

Litepaper

  • https://qu.ai/litepaper
  • Saved locally as quai-network-litepaper.pdf
    • Canonical official primer for the project’s own monetary-system framing.
    • Used mainly as the best primary document to store locally for future deeper passes.

Docs: whitepaper index

  • https://docs.qu.ai/learn/academic-resources/whitepapers
    • Best index of Quai’s own cited research lineage.
    • Used to confirm the specific papers the docs treat as foundational: BlockReduce, PoEM, the improved proof-of-work fork-choice paper, and proportional reward allocation work.

Docs: merged mining overview

  • https://docs.qu.ai/learn/advanced-introduction/merged-mining/overview
    • Best short primary source for Quai’s core scaling/security mechanism.
    • Used to confirm the hierarchy-based merged-mining story: one hash attempt checked against Prime / Region / Zone difficulty thresholds, shared security across chains, and coincident blocks as the basis for native cross-chain linkage.

Docs: PoEM overview

  • https://docs.qu.ai/learn/advanced-introduction/poem/poem
    • Best short primary source for Quai’s consensus differentiation.
    • Used to confirm how Quai describes PoEM versus ordinary proof-of-work: intrinsic block weight, entropy minimization, deterministic next-block preference, and the project’s claim that perpetual fork contention can be avoided.
    • Also important because it explicitly links current docs to the 2023 PoEM paper and the 2024 “A Better Proof-of-Work Fork Choice Rule” paper.

Docs: token dynamics

  • https://docs.qu.ai/learn/tokenomics/token-dynamics/token-dynamics
    • Best short primary source for the dual-token economic control surface.
    • Used to confirm the contrasting reward curves for QUAI and QI, miner choice over reward denomination, conversion between the two tokens at a rate tied to current reward schedules, and rolling difficulty adjustment as an economic feedback mechanism.

Reference implementation

  • https://github.com/dominant-strategies/go-quai
    • Best primary engineering source for the existence of an official reference client.
    • Used to confirm that Quai publishes an official Go implementation and exposes node configuration around slices / environments rather than treating the protocol as docs-only.

QIPs repository

  • https://github.com/quai-network/qips
    • Best primary source for the emerging standards/governance surface.
    • Used to confirm that Quai is already decomposing key control surfaces into separate proposal tracks such as sharded ledger design, cross-shard transactions, merge-mined transactions, Qi UTXO ledger design, dynamic tree expansion, interlinks, and reusable payment codes.
    • This is important because it shows that practical protocol authority will likely sit not only in the base research papers but also in how the QIP process evolves shard expansion, addressing, transaction routing, and token mechanics.

Research papers cited by official docs

  • https://arxiv.org/abs/1811.00125
    • BlockReduce: Scaling Blockchain to Human Commerce
    • Best source for the original hierarchy-of-merged-mined-chains design that later became Quai’s scaling story.
  • https://ieeexplore.ieee.org/document/9881846
    • Scalable Multi-Chain Coordination via the Hierarchical Longest Chain Rule
    • Useful for the formalized hierarchical-longest-chain treatment of the BlockReduce idea.
  • https://arxiv.org/abs/2303.04305
    • PoEM: Proof-of-Entropy-Minima
    • Best source for the earlier entropy-based fork-choice framing.
  • https://eprint.iacr.org/2024/200
    • A Better Proof-of-Work Fork Choice Rule
    • Best source for the later formal security framing around intrinsic-work-based fork choice.
  • https://arxiv.org/abs/2503.10185
    • Optimal Reward Allocation via Proportional Splitting
    • Useful for the newer reward-allocation branch that Quai docs treat as part of the protocol’s economic/security research stack.

Main takeaways from this pass

  • Quai is worth cataloging because it is not just another fast EVM or generic proof-of-work revival. Its primary materials expose four distinct mechanism layers that are analytically useful on their own: hierarchical merged mining, entropy-based fork choice, coincident-block cross-chain linkage, and a dual-token monetary system with protocol-native conversion.
  • The most reusable comparison lens is not raw TPS. It is who controls sharding growth, cross-shard routing, reward denomination, conversion pressure, and future hierarchy changes once the project moves from docs and research papers into live governance.
  • The QIPs repository matters more than many L1 governance repos because it already reveals where protocol complexity is likely to concentrate: shard addressing, merge-mined transaction semantics, Qi ledger design, and dynamic tree expansion.
