Control profile
- Transaction ordering
- PlasmaBFT validator committee launched as a small, trusted set; the documentation says broader consensus-node access and permissionless validation are future phases.
- Escape hatch
- n/a — L1; non-validator nodes are configured to trust a validator endpoint
- Upgrade authority
- Core consensus, committee formation, and proof-of-stake design remain under active development; no independent on-chain upgrade authority or exit window is documented.
- Liveness record
- Fast HotStuff-style finality reduces normal confirmation time, but the launch architecture intentionally keeps the validator set small. Rewards can be slashed while validator collateral is not, and the current documentation does not apply a separate liveness penalty.
Ketju assessment
REJECTED at the current phase. Plasma publishes a credible technical path toward a proof-of-stake L1, but the path is not the control state. Production consensus began with a selected validator committee, public validator participation has no fixed timeline, and committee formation is still described as under development. A non-validator can verify data but still follows a trusted validator for consensus. Until permissionless entry and upgrade authority are live and measurable, the chain remains controlled by its launch group.
Observable review triggers
- Revisit after permissionless consensus-node participation is live
- Revisit after validator identities, stake concentration, and upgrade authority are publicly measurable
- Revisit after twelve months of production under the decentralized validator design
These triggers make the judgment monitorable. They are not predictions; each identifies a fact that would revoke or force review of the current assessment.
Advisor implementation questions
- Does the client’s thesis require censorship resistance, or primarily low-cost settlement?
- Can the client exit without cooperation from the normal transaction-ordering party?
- Who can upgrade bridges or contracts, and what delay applies?
- Does the asset introduce an issuer weaker than the chain grade?
- What evidence will show a halt, censorship event, or governance change?
