abeychain adopts hybrid consensus, fPow + DPoS. The DPoS committee members use pbft protocol to produce fast blocks which include transactions and to confirm the previous snail blocks. The fPoW miners mine fruits (point to fast blocks) and snail blocks (include fruits) to resit the long range attack and to prevent tampering.
Reward
The business module of abeychain is deflation. The staking reward wil deflate 20% every year. From March 30th 2020, the annumal reward will be 3,000,000, 2,400,000, 1,920,000, ...
Validator
Validators are the DPoS committee members to process transactions. The minimum amount to be validator is 20,000 abey.
The recommended specifications for running a validator node is:
4 cores CPU
16G RAM
200G disk space
4Mpbs bandwidth
public ip address to participate the committee
Locked Time
Assets will freeze after staking. And 25,000 fast blocks(about 15 days) need to unfreeze.
Stake Guide
Stake/withdraw option is based a system contract, everyone can call the contract functions to do these actions. And the node provide some RPC APIs to request the stake and reward information. We also provide a staking CLI to stake easily.
Staking Contract
abeychain staking contract is deployed at address:
gabey will listen all ip address when giving --rpcaddr 0.0.0.0, you can give the exact ip address that want to connect, or --rpcaddr 127.0.0.1 only allow running on the host to connect gabey.
gabey support BFT
./gabey --bftip 39.98.251.xx console
bftip must be public ip, open firewall port 8545(rpc),30310(bftport),30311(bftport2)
Building impawn requires both a Go and a C compiler. Once the dependencies are installed, run
cd go-abey/cmd/impawn
go build -o impawn main.go query_stake.go impawn.go
Staking-CLI
The process of abeychain Staking-ClI is divided into three parts. First, on the premise of ensuring the balance of the account, Launch a Impawn transaction, only if the amount of deposit(value) is greater than 2W abey can participate in the election of the committee. If you ready to withdraw from the committee's POS consensus next epoch, Launch a Cancel transaction in the current epoch. After waiting for 15 days, we need to actively launch Withdraw transaction. The extracted abey will be immediately transferred to the specified account.
Since Impawn needs to be greater than 2W which can invoked successfully, Append can be used if the impawn amount is less than 2W.

querystaking print in staking count(Staked), already cancel count(Locked), can withdraw count(Unlocked)..
Print withdraw height, after this, you can call withdraw, if lock equal false, can instant withdraw .
If Unlocked not equal zero, can instant withdraw print amount.
