Create An EVM Compatible Blockchain Bridge——DB3 Network build in public weekly update (20230213-20230218)

Brief intro

We began to refactor our bill and gas system based, use the EVM chain to settle, and prepare for our network's economic model and the token release.

Besides, more CLI and db3.js features are implemented, such as:

• release a new version
• Feat/delete doc in CLI
• Create wallet/database/collection using db3.js

Key PRs:

use u64 to store the balance of bill and credit

Code:

Detail:

Show network status in CLI; CLI could show the status of the following concept:

DB-related concepts:

• ​ Database
• ​ Collection: aka 'table'
• ​ Document: aka 'record'
• ​ Mutation: aka 'write into / update'
• ​ Session: aka ‘query’
• ​ Storage: the storage size of your data

Account-related concepts:

• ​ Address:
• ​ Bills: bills are generated by the consumption of data mutation and storage
• ​ Credits: The credits are set by the initial number 10
