The team is currently working on the tokenomics engine (for the node rewards system) at the same time as a node explorer, as the same stats are needed both as inputs for the overall rewards payout calculations and as reported operational metrics for node operators.

That said, node rewards are not live yet during the current phase of beta testing. The reward system is planned to go live February, 2021.

Search rewards are live for searching the web with the engine.presearch.org and testnet-engine.presearch.org engines.
