Running an Operator is currently only available on the Chronos Testnet. On mainnet, only Subspace Labs and the Subspace Foundation are running operators. Community access to running operators on mainnet will be available in the future.

Autonomys introduces the Decoupled Execution Framework (DecEx) to tackle the state-bloat issue by separating transaction ordering from execution. Farmers confirm and order transactions, while staked operator nodes execute them, allowing different hardware requirements for each role. This keeps farming accessible and lays the groundwork for scalable execution. Users submit transactions to operators who batch them into bundles. Farmers verify and order them, with operators executing the transactions in this order. The process forms a deterministic receipt chain, with an initial implementation using an optimistic fraud-proof validation scheme.

Фермерство и операторы: Ключевые различия
Фарминг
- Consensus: This is the primary role of Farmers, and provides security and consensus for the network. Our Farmers are what ensure we don't trust, but verify.
- Упорядочивание транзакций: Фармеры отвечают за подтверждение доступности транзакций и обеспечивают упорядочивание.
- Невысокие требования: Требования к оборудованию для фарминга предполагаются невысокими, что делает его доступным для каждого.
- Верификация: фармеры только проверяют proof-of-election и обеспечивают наличие данных.
- Транзакции: Фармеры не выполняют транзакции, они сосредоточены на их упорядочивании и включении их в блокчейн.
Работа оператора
- Отправка и исполнение транзакций: Операторы отвечают за объединение транзакций в пакеты и их отправку в цепочку консенсуса, выполнение транзакций, включенных в блок консенсуса, и поддержание конечного состояния цепочки.
- Высокие требования к оборудованию: Операторам требуются более значительные аппаратные требования, поскольку они должны выполнять сложные операции.
- Require Initial Investment: Operators are required to stake a certain amount of AI3. If an operator acts maliciously, their stake is at risk of being slashed. Engaging in such malicious behavior carries significant penalties, providing crypto-economic security to execution.
- Пре-валидация и пакетирование: Операторы предварительно проверяют и формируют транзакции в пакеты через процесс выбора с учетом веса депозита.
- Детерминированное исполнение: операторы выполняют транзакции в конкретном детерминированном порядке, производя фиксацию состояния в виде квитанций об исполнении.
- Вторичная сетевая роль: Слежение за вредоносными действиями в цепочке домена и отправка доказательств мошенничества в цепочку консенсуса.
- Поддержка различных окружений: поддерживает различные окружения исполнения смарт-контрактов, такие, как виртуальная машина Ethereum (EVM) или Web-Assembly (WASM).

Структура каталогов
The operator key pair is stored in the keystore directory within your domain folder. In the example below, 0 represents the domain ID, which will vary based on which domain you're operating on.
Стейкинг
The Autonomys Network relies on staking from both domain operators and farmers to secure the network and provide resources. Autonomys implements a Nominated Proof-of-Stake algorithm where token holders endorse operators who execute transactions and produce blocks.
Наша модель стейкинга состоит из двух уровней:
-
Farmers earn rewards proportional to their pledged storage. Farmers can choose to nominate operators and back them with their own stake, increasing their chance of being elected as a slot leader. Farmers, who have earned storage rewards, nominate operators to execute transactions. This nomination system balances the power between farmers who nominate and operators with both parties sharing the execution fees and the potential penalties (slashing).
-
Operators stake to gain the right to produce bundles within a domain. They are responsible for validating and executing transactions, producing execution receipts, applying state transitions, submitting a storage fee for bundle execution and earning fees for their work. The operator's chances to be elected as a slot leader and produce a bundle are weighted by their stake. Operators can be nominated by farmers or other AI3 holders.
The nomination pools in Autonomys are "lazy": any fees earned by the operator are assigned to the pool and are not deposited to the nominators wallet unless they ask for a withdrawal. Unless withdrawn, the fees are "auto-staked" - they count towards the total stake of the pool, increasing its chance of being elected to produce bundles.
Nominations
Any $AI3 token holder with the required nominator MinStake can join an operator's nomination pool by submitting a nomination transaction with their desired $AI3 stake deposit. The workflow is then as follows:
-
The nominator's $AI3 deposit is added to the list of pending deposits in the nomination pool.
-
At the end of the epoch, the nominator's deposit is processed.
-
20% of each nominator's deposit is reserved in the operator's storage fee fund to pay for bundles the operator creates. This does not affect the stake distribution and is proportionally refunded with each withdrawal. The remaining 80% is locked in the nominator's wallet.
-
The nominator's share of the total pool is calculated based on their deposit as a percentage of the total stake and their length of time staked. This is used to calculate the nominator's share of the operator's execution fees.
Эпоха стейкинга
The stake epoch is a designated period in domain blocks within a blockchain system that marks each stake allocation re-adjustment period. Occurring every StakeEpochDuration blocks (at the moment, it's set to every 100 blocks or ~10 minutes), an epoch transition triggers specific actions such as finalizing operator domain switches, deregistering operators, unlocking operators and their associated funds, and recalculating stake distribution for the Verifiable Random Function (VRF) election. These transitions are designed to adjust the stake distribution dynamically, finalize various staking-related operations, process rewards, and manage deposits and withdrawals. The uniform duration across all domains helps maintain consistency in the network, while the specific starting point for each domain's epoch transition may vary based on when it is registered, helping to amortize the load of these transitions.
Withdrawals
Withdrawals have a locking period of 14,400 domain blocks (~1 day), after which withdrawn tokens are unlocked in users' wallets. All withdrawals requested in the same stake epoch are aggregated together, and the total amount is unlocked at once. This locking period is necessary to ensure that the domain block executing the withdrawal is confirmed and not challenged by a fraud proof, increasing the economic stability of domains.
