3. Deposit and Stake

Deposit sufficient amount of BTC to help process transactions (sBTC for testnet). The operator is required to stake 1 BTC as a security deposit before processing transactions (the 1 BTC is time-locked and self-custody, kept under operator's address). If an operator is found acting maliciously (e.g. attempting to steal funds), the deposit will be slashed as a penalty. The deposit can be unstaked when the operator chooses to exit.

Here's how to deposit and stake:

1. Deposit Funds

Transfer sufficient BTC to the operator's main address. To successfully complete the staking, you need at least stake_amount + dust + gas BTC.

• Note: Fiamma Operator is running on Bitcoin Signet during testnet. Please deposit sBTC to the main address.

Currently, stake_amount is 1 BTC, so deposit at least 1.00001 BTC. Since subsequent work requires 12 BTC, we recommend an operator to transfer at least 13.00001 BTC initially.

1. Stake Funds

When the operator's main address has sufficient BTC, execute the following command to complete staking:

./bcli operator -n beta-testnet stake

Check staking status:

./bcli query -n beta-testnet stake -a <MAIN_ADDRESS>

Once the staking status shows committee_signed, wait around 10 minutes for the transaction to be confirmed on-chain. After that, you can check your operator status:

./bcli query -n beta-testnet operator -a <MAIN_ADDRESS>

If the status is Active, it means the operator has completed the staking process and has started working.
