Vector Zulu — ULL Transaction Tracker
|
||||
Tracks transactions through the KoreNet Universal Ledger Layer.
|
||||
|
||||
ULL status progression:
|
||||
POSTED → SETTLED → SYNCED → ANCHORED → VERIFIED
|
||||
|
||||
Monitors all VZ transactions to ensure full fabric compliance.
|
||||
Queues KoreChain anchor at each stage transition.
|
||||
Triggers Ethereum anchor on VERIFIED.
|
||||
|
||||
Runs on api.korenet.cloud (requires AKS pods up).
