Обзор архитектуры управления и смарт-контрактов.
Обзор архитектуры управления
Ончейн-управление dYdX позволяет следующее:
Создавать предложения и голосовать по ним
Получать снимки находящихся во владении токенов в начале процесса внесения предложения
Делегировать отдельные права голоса и права на внесение предложений
Устанавливать пороговые значения для управления, в том числе для числа предложений, кворума, а также разницы в количестве голосов
Заменить смарт-контракт стратегии управления V2, определяющий принцип подсчета голосов
Настраивать несколько контрактов исполнителя, которые позволяют следующее:
быстро вносить изменения в протокол и распределять средства благодаря исполнителям с правом на короткую блокировку по времени;
модернизировать процесс управления благодаря исполнителям с правом на длительную блокировку по времени.
Существует 7 смарт-контрактов, обеспечивающих управление dYdX:
Контракт на токен DYDX
Контракт на обернутый токен Ethereum Dydx
Контракт управляющего DYDX
Контракты исполнителя
****Контракт на приоритетную блокировку по времени периода приоритета (7 дней) до окончания задержки блокировки по времени.
Контракт на стратегию управления V2
Контракт на модуль безопасности
Открытый исходный код и проверка
Весь исходный код смарт-контракта для контрактов на управление и пулы стейкинга можно найти по адресу https://github.com/dydxfoundation/governance-contracts .
Исходный код интерфейса управления dydx.community, можно найти здесь .
Все новые основные смарт-контракты прошли проверку компанией Peckshield. Важных или высокоприоритетных проблем безопасности не обнаружено. Базовые контракты на управление и токены получены в результате форка кодовой базы контрактов на управление Aave, которые прошли проверку CertiK , Certora и Peckshield и в течение многих месяцев испытывались на практике в основной сети.
Базовые контракты на управление
Токен DYDX
Контракт на токен DYDX был вдохновлен протоколом Aave. Специалисты dYdX внесли в него незначительные изменения.
Контракт на токен DYDX развернут в основной сети Ethereum по адресу 0x92D6C1e31e14520e676a687F0a93788B716BEff5 .

Контракты вознаграждений в виде DYDX
Дистрибьютор Меркла
Смарт-контракт дистрибьютора Меркла распределяет награды в виде токенов $ethDYDX согласно балансам дерева Меркла. Дерево может периодически обновляться с учетом совокупного баланса наград каждого пользователя, что позволяет распределять новые награды между ними с течением времени.
Обновление выражается в установке последнего значения, возвращенного контрактом оракула, для предложенного корня Меркла. Предложенный корень Меркла может быть активен после периода ожидания. В течение периода ожидания управление dYdX может заморозить корень Меркла в случае, если предложенный корень неверный или содержит вредоносный код. Исполнитель с правом на короткую блокировку по времени может возобновить процесс обновления корня.
Смарт-контракт дистрибьютора Меркла был вдохновлен проектами Uniswap и Badger. Смарт-контракт развернут в основной сети Ethereum по адресу 0x01d3348601968aB85b4bb028979006eac235a588 .

Модуль безопасности представляет собой пул стейкинга, который распределяет награды в виде токенов $ethDYDX между пользователями, размещающими $ethDYDX в стейке с целью защиты протокола.
Награды для поставщиков ликвидности
Модуль ликвидности представляет собой набор смарт-контрактов для стейкинга и займа, которые стимулируют распределение средств в виде $USDC с целью поддержания двусторонних котировок на бирже dYdX уровня 2.
Стейкеры получают награды $ethDYDX за стейкинг $USDC. Предварительно утвержденные партнеры могут заимствовать размещенные в стейке средства на основе репутации и без залогового обеспечения. Средства можно использовать только на бирже уровня 2, что обеспечивается контрактом StarkProxy, который взаимодействует с контрактом StarkEx Perpetual Exchange.
StarkProxy
Этот контракт позволяет своему владельцу заимствовать средства из стейка ликвидности и использовать их в рамках контракта StarkPerpetual. Владелец может вносить дополнительные средства, и любые средства, превышающие сумму займа, можно беспрепятственно вывести. Этот контракт взаимодействует с контрактом StarkPerpetual , созданным Starkware, а также проверенным и развернутым ранее.
Контракты казны
Контракт на вестинг казны был вдохновлен протоколом Uniswap .
Контракт на короткую блокировку по времени может выполнять только те действия, что утверждены управлением.
Существует два казначейских шестеро и контракта казны:
Поскольку управление контролирует каждую казну, оно может переводить средства на любой адрес и/или позволять какому-либо адресу расходовать средства любой казны. Например, управление должно будет установить лимиты для токенов в рамках программ вознаграждения.
В рамках ППУ 29 сообщество dYdX проголосовало за использование смарт-контрактов казначейского моста наград и казначейского моста сообщества , что позволило перенести доступные ethDYDX из казны сообщества и казны наград в цепочку dYdX.
Каждый контракт на фистинг казны будет осуществлять фистинг токенов равными частями на протяжении \примерно 5 лет (с 3 августа 2021 г. по 3 августа 2026 г.) в соответствующую казну. Поскольку контракты на фистинг являются неизменными при развертывании, сообщество dYdX проголосовало за установку получателя контрактов на фистинг по следующим адресам:

Награды на базе оракула Chainlink (награды за торговлю и обеспечение ликвидности)
Цель этой системы — расчет и публикация наград в виде токенов ethDYDX, заработанных трейдерами на бирже dYdX уровня 2, с помощью децентрализованной сети подписантов оракула. Награды хранятся в дереве Меркла, где содержатся совокупные награды каждого пользователя, полученные с начала запуска программы распределения. Каждую эпоху корень Меркла обновляется согласно смарт-контракту MerkleDistributorV1, чтобы показать награды, заработанные за последнюю эпоху.
Для ончейн-публикации данных о наградах мы обеспечили интеграцию с системой-оракулом Chainlink. Для публикации данных о торговле, которые Chainlink использует для создания дерева Меркла, мы используем систему IPNS. Используя систему IPNS, мы можем размещать торговые данные за последнюю эпоху по той же ссылке IPNS, что и за предыдущие эпохи, обеспечивая аналогичное расположение данных.
После расчета соответствующих наград на основе необработанных торговых данных Chainlink публикует дерево Меркла наград в протоколе IPFS. Информация об архитектуре системы вознаграждения Chainlink на базе оракула приводится на следующей диаграмме:
