DB3 token

1 db3 = 1000_000_000 tai

the gas price sheet

1M data will cost 1 db3

create an empty database

assume the encoded database byte size is 100 bytes

gas_fee =     100            +        100 * 1 
              create_db      database meta bytes

create a database with one collection and one index

assume the encoded database meta byte size is 300 bytes

gas_fee =     100       +         100            +         100         +      300 * 1
