Answers

Proxy ledgers store copies of blockchain transactions that are maintained by proxy agents that are co-located with the master node. They facilitate fast processing and updating of transactions across geographically dispersed nodes.

Proxy smart contract agents perform actions on behalf of other nodes, such as endorsing transactions, thereby reducing latency and increasing transaction processing speed. They also maintain the ledger and submit their transactions to their own copy of the ledger, thus facilitating distributed ledger maintenance.

In this context, "co-location" refers to the location of the proxy smart contract agent physically closer to the master node, or installed on the same node, allowing for faster communication and reduced latency.

The proxy ledger allows transactions to be processed and submitted locally without waiting for confirmation from other geographically dispersed nodes. This localized processing speeds up transactions because network-wide consensus does not need to occur at every step.

The frequency of updates between the proxy smart contract agent and the node it represents depends on factors such as available cache size, network load, and the level of synchronization required across nodes.

The proxy agent actively updates block-related metadata (such as Merkle tree hashes and lists of submitted transactions), while the actual content of the block's transactions is updated passively later. This two-phase approach optimizes network bandwidth and reduces latency.

The proxy agent helps avoid double spending by maintaining locally available pools of resources. These pools represent portions of global resources, allowing transactions to be validated and executed locally without the need for immediate global synchronization.

Global resource partitioning can cause latency when queries need to be made to resources located in different geographical regions. Accessing and retrieving this remote data increases the overall time for transaction processing.

In a cloud deployment environment, proxy nodes and local nodes can coexist as virtual machines or containers on the same physical infrastructure. This co-location reduces latency, while virtualization provides trust and security isolation.

“Hyperledger” refers to the entire distributed ledger system, including resources and ledger partitions distributed across geographical regions, and passive coordination with the proxy ledger. It is a superset of the aggregate ledger maintained by each node.
