Вопрос по солидити Скажем я хочу сделать смарт контракт для соц
сети и мне нужно организовать систему подписок и отписок
Как это можно сделать? Хранить адреса подписчиков пользователя в массиве не получится, потому что при отписке не получится удалить элемент
Хранить вот так mapping(address=>(mapping(address=>bool)) тоже не получается, потому что не получается всех подписчиков агрегировать
