Risk Disclaimer:
Our project is still in the mainnet Beta version. The security audit is still in progress.
The 0.1 BTCB you deposit to the DeCus system will be staked for 6 months at most and cannot be withdrawn during this period. 
Joining in our system in this early stage should be considered of high risk, please participate at your own risk.
About Keepers
Who are Keepers? In the system of DeCus, Keepers are responsible for the custody of underlying crypto assets. All keepers are organized under the overlapping group assignments in a 100% decentralized way. Anyone who wants to become a Keeper need to deposit collaterals and run a Keeper node. 
What Do You Need?
To create a keeper node you require：
Time and patience
The whole process takes over half an hour, and may be interrupted by some faulty operations, but we still recommend trying to get it done all in one go.
A new Bitcoin wallet
Please create a new BTC address, and don't send any asset to this address.
Please don't use hardware wallet.
A new Binance Smart Chain wallet, 0.1 BTCB and BNB
Please create a new BSC address, and don't send any asset to this address except staked BTCB and some BNB for paying gas fee.
Please don't use hardware wallet.
A server
 Please use a server with 1CPU core and 1GB RAM. You can purchase one on Digital Ocean or Alibaba Cloud.
If you purchase on Digital Ocean, please choose the "Password" option when you proceed to the Authentication step.
After the successful purchase, remember to save the IP address and password of the cloud server for later use.
All the preparations are done! Let’s get this going!

How to Leave the Network?
In order to test the system's ability to run stably for a long time, the BETA version will keep running for about 6 months, during which the keeper nodes cannot leave the network and the BTCB they staked to the platform will be locked in the contract and cannot be redeemed. The exit function may go live earlier depending on the operation of the system, the specific time and steps about how to leave the network will be announced through official channels, please keep up with our website, Twitter and Discord.
Risk Disclaimer:
Our project is still in the mainnet Beta version. The security audit is still in progress, and the system has not gone through any penetration test yet. The 0.1 BTCB you deposit to the DeCus system will be staked for 6 months at most and cannot be withdrawn during this period. Although we have established several risk prevention mechanisms to safeguard all assets, participating in our system in this early stage should be considered of high risk, please assess the potential uncertainties carefully.
