Node staking. Allow external users to run validator nodes, and users can be rewarded by staking.

Gas price prediction base on the txpool, and with a rpc interface eth_gas Price Prediction for query;
Jam index (a quantitative index) for accessing the transaction jam status quantitatively, it's a metrics for this index, and also a rpc interface for query: txpool_jamIndex;

Now the EstimateGas will return a non-exact value in order to improve the performance, and the returned gas value will be greater than the exact one, and with an error range less than 4000 gas.
