Dependencies
What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Consensus algorithmenablesReplicationEstablished
Consensus keeps replicas consistent.
Mechanism: A consensus protocol (e.g. Paxos, Raft) makes replicas agree on the same ordered log of updates, so a replicated state machine stays consistent despite failures.
System context
Consensus algorithmis part ofDistributed computingEstablished
Consensus underpins distributed systems.
Mechanism: It lets separate machines agree on one value despite crashes and delays, so they act as a single reliable service.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Directly enables 1 concept; following enables/causes relations, 4 concepts are downstream across 2 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 3 of 3 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Structural neighbourhood: 3 → 9 → 12 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 3 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Replication and CAP theorem.
Through this lens it connects to Replication, CAP theorem and Distributed computing.
