Worker

The Worker account represents a registered worker in a queue.

Seeds: ["worker", queue, wallet] — one registration per worker per queue.

Fields

Field	Type	Description
queue	Pubkey	Parent queue
wallet	Pubkey	Worker's signing wallet
stake_amount	u64	Tokens currently staked
jobs_completed	u32	Lifetime successful completions
jobs_failed	u32	Lifetime failures (slashes)
total_earned	u64	Lifetime reward earnings
active_jobs	u8	Currently held jobs
max_concurrent_jobs	u8	Hard cap (snapshotted from queue config)
is_active	bool	Active flag
registered_at	i64	Unix timestamp

Notes

• max_concurrent_jobs is copied from the queue's config at registration time. If the admin later changes the queue's max_concurrent_jobs, existing workers keep their original value. New workers get the updated value.
• A worker cannot deregister while active_jobs > 0. All held jobs must complete or expire first.
• Workers can increase_stake at any time to add more tokens.
• stake_amount decreases when the worker is slashed (via reclaim_expired or resolve_dispute where worker loses).
