Vitalik Buterin (co-founder of Ethereum) writes that there are 3 axes (dimensions) of decentralization.
- Architectural (de)centralization — how many physical computers is a system made up of? How many of those computers can it tolerate breaking down at any single time?
- Political (de)centralization — how many individuals or organizations ultimately control the computers that the system is made up of?
- Logical (de)centralization— does the interface and data structures that the system presents and maintains look more like a single monolithic object, or an amorphous swarm? One simple heuristic is: if you cut the system in half, including both providers and users, will both halves continue to fully operate as independent units?
Even if an IdeaGraph is split, the post-split portions can continue to function as logically independent IdeaGraphs, thus resulting logically decentralization. Using Buterin’s 3-axes (dimensions) of decentralization, the IdeaGraph surpasses Blockchain.
