admin.nodeInfo		Provides detailed information about the node.
eth.syncing	curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "eth_syncing","params": []}' localhost:8545	Indicates whether the node is syncing (true) or not (false).
eth.syncing.highestBlock - eth.syncing.currentBlock		Compares the current block of your node to the highest block.
eth.blockNumber	curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "eth_blockNumber","params": []}' localhost:8545	Returns the latest block number processed by the node.
debug.setHead("0x"+((eth.getBlock('latest').number) - 1000).toString(16))		Rewinds the blockchain to 1000 blocks prior.
admin.nodeInfo.enode		Retrieves the public enode URL of the node.
eth.syncing.currentBlock * 100 / eth.syncing.highestBlock		Calculates the remaining percentage for block synchronization.
eth.getBlock("latest").number	curl http://YourIP:8545 -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0", "id":1, "method":"bor_getSigners", "params":["0x98b3ea"]}'	Queries the height of the latest Bor block.
