METHODS AND SYSTEM OF TRACKING TRANSACTIONS FOR DISTRIBUTED LEDGER

Abstract:

A tracker computer does not contribute content for inclusion in: a distributed ledger, a transaction, and a blockchain that records the transaction. In an embodiment that reduces network bandwidth needed by a blockchain network, the tracker computer receives, from first client computers, requests to track execution of transactions in a blockchain network that has multiple ledger computers and does not include the tracker computer. The tracker computer subscribes to the ledger computers for status notifications from the execution of the transactions. The tracker computer receives status notifications that indicate status of the transactions that occurred after the clients' subscribing for status notifications. The tracker computer records the status of the transactions. The tracker computer pushes the status of the transactions to the first client computers. From second client computers, the tracker computer receives pull requests for status of the transactions in the blockchain network. To the second client computers, the tracker computer sends the status of the transactions as already recorded by the tracker computer.
