On-chain rent machine

Step 1: Determine the machine to be rented

• Open Mainnet Wallet

• Create a wallet: Account-->Add account (The mnemonic phrase must be saved, if the mnemonic phrase is lost, the account cannot be retrieved, and the currency is lost)

• Go to Galactic Race Machine List to find the corresponding type of idle machine

find_machine

Step 2: Rent a machine on the chain

• Navigate to Developer---Transactions---rentMachine ----rentMachine(machine_id, rent_gpu_num, duration)

• machine_id: Enter the id of the machine to be rented, the 0x in the input box must be deleted first

• rent_gpu_num: Enter the number of GPUs to rent this time (no more than the machine's free GPU count; billing is per-GPU and one machine can be rented by multiple renters)

• duration: Enter the time to be rented (unit: 1 BlockNumber = 6 seconds, the minimum rental time is 300 blocks. If it exceeds half an hour, it must be a multiple of 300 blocks. )

• After the input is complete, click Submit Transaction. On success a rent order id rent_id is generated (see it in the rentMachine.Rent event, or query Developer-Chain state-rentMachine-userOrder(your account)). Use this rent_id for confirm and relet below.

• After submitting, confirm whether the machine is available within 30 minutes. (If the lease is not confirmed within 30 minutes, the payment of dbc will be refunded, but the transaction fee of 10 dbc cannot be refunded)

• For related operations such as creating a virtual machine, please reference

Step 3: Confirm availability and lease

Note

Before confirming, you must confirm that the virtual machine can start normally. After confirming that the lease is successful, it means that the machine is successfully leased, and the DBC rent cannot be refunded

• Navigate to Developer----Transactions----rentMachine----confirmRent(rent_id)

• Enter the rent_id obtained in Step 2 and submit the transaction

Step 4: Relet Machine Rent

Note

The virtual machine will be automatically stopped when the machine expires to ensure that the lease is renewed successfully before the lease expires

• Navigate to Developer----Transactions----rentMachine----reletMachine(rent_id, relet_duration)

• Enter the rent_id and the renew duration (relet_duration, in blocks, must be a multiple of 300; e.g. 14400 for one more day), and submit the transaction
