A fast Move L1 facing real questions about validator concentration and node cost.

L1PoS (Move)
Type
L1 · PoS (Move)
How it works
Delegated PoS with a permissioned-feeling validator set; high-throughput design makes running a full node expensive, which limits who participates.
Nakamoto coefficient
Concentrated
Node / validator set
~100+ validators (stake concentrated)
Client diversity
Single dominant client
Governance
Foundation-influenced
Key risk
Validator concentration; pricey nodes

Assessment

Sui delivers high performance but draws ongoing criticism over decentralization: validator stake is concentrated, full nodes are costly to run, and the foundation retains significant influence — concerns that grow as institutions scrutinize decentralization claims.

Decentralized here

  • Modern Move-based design
  • Growing developer ecosystem
  • Fast finality

Centralization vectors

  • Validator stake concentration
  • Expensive to run a full node
  • Foundation influence on the validator set
C-

Verdict

Performance-first, with decentralization still a work in progress.
