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, поддерживающих управление dYdX:

  • Контракт на токен DYDX: содержит снимки, которые поддерживают запросы на получение права голоса и права на внесение предложений адресов в любом номере блока. Поддерживает делегирование отдельных прав голоса и прав на внесение предложений.

  • Контракт на обернутый токен Ethereum Dydx: содержит снимки, которые поддерживают запросы на получение права голоса и права на внесение предложений адресов в любом номере блока. Поддерживает делегирование отдельных прав голоса и прав на внесение предложений.

  • Контракт управляющего DYDX: отслеживает и может исполнять предложения с помощью смарт-контракта на блокировку по времени.

  • Контракты исполнителя: может помещать в очередь, отменять или выполнять операции, за которые проголосовало управление. Если предложение принято, то с помощью контракта исполнителя, указанного в предложении, можно вызывать функции. С помощью контракта исполнителя можно определять продолжительность задержки, с которой выполняются операции, находящиеся в очереди.

  • ****Контракт на приоритетную блокировку по времени: аналогичен контракту на блокировку по времени, но позволяет контролеру приоритета исполнять операции в течение периода приоритета (7 дней) до окончания задержки блокировки по времени.

  • Контракт на стратегию управления V2: содержит логическую схему подсчета голосов. В настоящее время подсчитываются голоса от токена $ethDYDX, токена $wethDYDX и $stkDYDX. Может быть модернизирован с помощью длительной блокировки по времени.

  • Контракт на модуль безопасности: содержит логическую схему стейкинга токенов DYDX, токенизации размещенной в стейке позиции и получения наград при сохранении права голоса и права на внесение предложений, а также функций делегирования базовых токенов.

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 вознаграждения в виде токенов $ethDYDX согласно балансам дерева Меркла. Дерево может периодически обновляться с учетом совокупного баланса вознаграждений 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

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 кассы

Контракт на вестинг казны был вдохновлен протоколом Uniswap.

Контракт на короткую блокировку по времени может выполнять только действия, утвержденные управлением.

Существует два вестера кассы и контракта кассы:

Поскольку управление контролирует каждую кассу, оно может переводить средства на любой адрес и/или позволять какому-либо адресу расходовать средства любой кассы. 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 вестер контракта будет наделять токенами равными частями на протяжении \примерно 5 лет (с 3 августа 2021 г. по 3 августа 2026 г.) соответствующую кассу. Поскольку вестер-контракты являются неизменными при развертывании, сообщество dYdX проголосовало за установку получателя контрактов на вестинг по следующим адресам:

Периферийные контракты

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 вознаграждениях 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 вознаграждений в протоколе IPFS. Информация об архитектуре системы вознаграждения Chainlink на базе оракула приводится на следующей диаграмме:
