LP-6480: LuxDA Operator Roles

Abstract

This LP defines the operator roles and commitment requirements for the LuxDA Bus ecosystem. Operators choose which services to provide and stake accordingly.

Motivation

This specification formalizes the component design, ensuring consistent implementation across the LuxDA ecosystem.

Specification

1. Operator Roles

Role	Responsibilities	Min Stake
Header Validator	Consensus, header ordering	100K LUX
DA Operator	Blob storage, availability	50K LUX
Store Provider	Long-term storage, queries	25K LUX
Index Provider	Query indexing, search	10K LUX
Relay Node	Message propagation	5K LUX
TFHE Committee	Threshold decryption	50K LUX

2. Role Registration

type OperatorRegistration struct {
    OperatorID    Identity
    Roles         []RoleType
    Stake         *big.Int
    Endpoints     []string
    Capacity      RoleCapacity
    Commission    uint16  // Basis points
}

type RoleCapacity struct {
    StorageGB     uint64
    BandwidthMbps uint64
    ComputeUnits  uint64
}

3. Commitment Requirements

Each role has service level requirements:

type ServiceCommitment struct {
    Role           RoleType
    Uptime         float64  // 99.9% typical
    Latency        uint32   // Max ms
    Availability   float64  // Data availability %
    ResponseRate   float64  // Request response %
}

var DefaultCommitments = map[RoleType]ServiceCommitment{
    RoleHeaderValidator: {Uptime: 0.999, Latency: 100},
    RoleDAOperator:      {Uptime: 0.999, Availability: 0.999},
    RoleStoreProvider:   {Uptime: 0.99, ResponseRate: 0.99},
}

4. Role Combinations

Operators can combine roles:

Full Node = Validator + DA + Store + Relay
DA Full   = DA + Store
Light     = Relay only

Rationale

The design follows established patterns in the LuxDA architecture, prioritizing simplicity, security, and interoperability.

Backwards Compatibility

This specification introduces new functionality and does not modify existing protocols. It is fully backwards compatible with existing implementations.

Security Considerations

Implementations must validate all inputs, enforce access controls, and follow the security guidelines established in the LuxDA Bus specification.
