Ena ke karolo ea bobeli letotong la lihlooho tsa thuto mabapi le ho theha likonteraka tse bohlale Python ho Ontology blockchain network. Sehloohong se fetileng re ile ra tloaelana le Konteraka e bohlale ea Ontology.
Kajeno re tla tšohla mokhoa oa ho sebelisa mojule oa bobeli— Storage API. Storage API e na le li-API tse hlano tse amanang le tsona tse lumellang ho eketsa, ho tlosoa, le liphetoho ho boloka ho tsitsitseng ka likonteraka tse bohlale ho blockchain.
Ka tlase ke tlhaloso e khuts'oane ea li-API tsena tse hlano:

1. Mokhoa oa ho sebelisa Storage API
GetContext & GetReadOnlyContext
GetContext и GetReadOnlyContext fumana moelelo oa taba eo konteraka e bohlale ea hona joale e etsoang ho eona. Theko ea ho khutlisa ke ho fapana le hash ea konteraka e bohlale ea hajoale. Joalokaha lebitso le bolela, GetReadOnlyContext e nka moelelo wa ho bala feela. Mohlaleng o ka tlase, boleng ba ho khutlisa ke pherekano ea hashe ea konteraka e hlahang hukung e kaholimo ho le letona.

Mosebetsi beha e ikarabella ho boloka data ho blockchain ka mokhoa oa dikishinari. Joalokaha ho bontšitsoe, beha e nka liparamente tse tharo. GetContext e nka moelelo oa konteraka e bohlale e sebetsang hajoale, senotlolo ke boleng ba senotlolo se hlokahalang ho boloka data, 'me boleng ke boleng ba data e lokelang ho bolokoa. Hlokomela hore haeba boleng ba senotlolo bo se bo le ka lebenkeleng, ts'ebetso e tla ntlafatsa boleng ba eona bo lumellanang.
Get
Mosebetsi Get o ikarabella ho bala data ho blockchain ea hajoale ka boleng ba bohlokoa. Mohlala o ka tlase, o ka tlatsa bohlokoa ba bohlokoa ho phanele ea likhetho ka ho le letona ho etsa mosebetsi le ho bala data e tsamaellanang le boleng ba bohlokoa ho blockchain.
