Internet Systems
Distributed intelligence infrastructure
Network foundations → OSI/TCP-IP → transport → application → security → distributed systems → cloud → sovereign infrastructure → governance → frontiers.
Network Foundations
Topology, Capacity, and Architecture
The network as a graph, packet switching, addressing and namespaces, capacity/latency/throughput, and the end-to-end principle.
OSI & TCP/IP
The Layered Protocol Stack
Layered architecture, the Internet Protocol, link-layer framing, routing as optimization, and protocol stack composition.
Transport Protocols
Reliability, Flow, and Congestion
Reliability as a state machine, congestion control, UDP and unreliable transport, flow control and windowing, and QUIC's reunification of the transport layer.
Application Protocols
HTTP, DNS, and Interface Contracts
HTTP request/response, hierarchical DNS resolution, email as the federation baseline, streaming and realtime delivery, and APIs as interface contracts.
Secure Communication
Cryptography, TLS, and Zero-Trust
Threat models and adversaries, symmetric and public-key cryptography, the TLS handshake, the post-quantum transition, and zero-trust architecture.
Distributed Systems
CAP, Consensus, and Fault Tolerance
FLP and CAP impossibility results, Paxos and Raft, Byzantine fault tolerance, replication and consistency models, gossip protocols, and content-addressed storage.
Cloud & Infrastructure
Virtualization, Orchestration, and the Edge
Virtualization and isolation, orchestration as a control loop, observability and telemetry, the economics of cloud scale, and CDNs and edge computing.
Sovereign Infrastructure
Federation, Identity, and Portability
Sovereignty as an architectural property, federation protocols, asymmetric identity and signatures, content addressing and portability, node-level governance, BrainFoundry as federated cognition, and the sovereign-versus-centralized tradeoff.
Internet Governance
Standards, Jurisdiction, and the Commons
The multi-stakeholder model, standardization as coordination, net neutrality, jurisdictional fragmentation, and the internet as a public good.
Frontier Architectures
Content Addressing, P2P, and AI-Native Protocols
Content-addressed networks, peer-to-peer systems and DHTs, programmable consensus, post-quantum networking, federated intelligence infrastructure, and AI-native network protocols.
