QKC DEVs have finally created smart contract which will allow small staker to stake their QKC native coins and earn back some interest. Contract code can be found on their github page on following link:
https://github.com/QuarkChain/quarkchain-contracts/blob/master/contracts/StakingPool.sol
QKC POWS RENT deployed contracts, at the time of writing, on chain 1 and chain 2 with following wallet addresses:
Chain1
0xDe04A5a1723c835e4245E33E91325a0831233bCc00015707
Chain2
0x89E880840dC1278351345ADf31c7377C898B016200025707
Chain3
0xDd9Db87AF14076abE0751DBD8BF216FFAc58699900036a28
More contracts might be created based on users feedback
Staker can send their QKC to above mentioned contract wallets in minimal amounts of 20k QKC for chain1 and 40K QKC for chain2, using gas limit of 200,000. Coins and contract have to be on same chain (if you wish to stake coins on chain2 contract, move coins to chain2 before sending them to contract address otherwise transaction will fail). At the time of writing chain2 have much lower mining difficulty and it is more favorable for mining. Please feel free to join our Telegram group and ask admin which chain is most favorable at the moment.
BEFORE SENDING BIGGER AMOUNTS OF QKC TO CONTRACT MAKE SURE YOU UNDERSTAND HOW TO USE IT!
