BuilderNet primary sources

Collected: 2026-05-10 UTC

Primary sources reviewed

  • https://buildernet.org/
    • Official landing page
    • Used to confirm BuilderNet’s core public framing: decentralized block building for Ethereum, TEE operation, and community MEV sharing
  • https://buildernet.org/blog/introducing-buildernet
    • Official launch / architecture rationale post
    • Used to confirm the multioperator design, first-release operator set, anti-exclusive-orderflow framing, compliance-policy diversity, and roadmap caveats around permissioned entry and centralized dependencies at launch
  • https://buildernet.org/docs/architecture
    • Official architecture overview
    • Used to confirm the five main actors, builder-node data flows, BuilderHub / Redistribution Archive dependency, and attested secret-and-configuration provisioning model
  • https://buildernet.org/docs/flashbots-infra
    • Official BuilderHub / Redistribution Archive explanation
    • Used to confirm BuilderHub responsibilities (identity, provisioning, peer discovery) and the Redistribution Archive’s role in MEV redistribution accounting
  • https://buildernet.org/docs/send-orderflow
    • Official orderflow-ingress docs
    • Used to confirm direct and regional endpoints, automatic propagation across nodes, request-signature requirements, and the fact that Flashbots Protect / Bundle Relay orderflow is automatically shared with BuilderNet
  • https://buildernet.org/docs/encryption-attestations
    • Official orderflow encryption and attestation docs
    • Used to confirm TEE-bound local TLS certificates, aTLS certificate serving on port 7936, and measurement-verification workflow for advanced users
  • https://buildernet.org/docs/api
    • Official API reference
    • Used to confirm orderflow methods, refund-API shapes, bundle-hash semantics, and the ability to delegate refund recipients
  • https://github.com/flashbots/builder-hub
    • Canonical BuilderHub repository
    • Used to verify that BuilderHub is a live open-source control-plane component rather than a docs-only concept
  • https://raw.githubusercontent.com/flashbots/builder-hub/main/README.md
    • Raw repository README
    • Used to confirm BuilderHub’s public API table, admin endpoints, and the specific responsibilities around registration, configuration, measurements, and builder activation

Notes

  • BuilderNet’s key mechanism is not merely “TEE block building.” It is multioperator shared block building plus explicit MEV redistribution from a common orderflow and bid archive.
  • The most important current control surfaces are BuilderHub, the Redistribution Archive, permissioned operator admission, and the measurement / attestation allowlist process.
  • The decentralization claim is therefore credible as a direction but incomplete as a present-tense fact; the primary sources are unusually explicit about the remaining training wheels.
  • This entry belongs in the corpus because it is a strong comparison class for Jito, MEV-Boost, Flashbots, and emerging orderflow / block-building systems where private ingress, operator admission, and refund logic determine who captures execution rents.
