Disclaimer

This release involves consensus changes (explained below). To avoid wasting mining power, please upgrade the cluster to this release before Tuesday, Apr 12, 2022, 00:04:00 AM GMT.

Updates

• * Add a self-adjusting mechanism to increase the network's hash power by lowering the effective difficulty for root chain PoSW stakers. (QCEP-7)

(Those items listed with asterisk * mean they are consensus changes and would lead to forks if clients are not updated accordingly.)

Notes

To change miner coinbase address:

./change_coinbase.sh 1000000000000000000000000000000000000000

GPU mining shard ID

Instructions for Ethash GPU mining

ethminer -U http://$CLUSTER_IP:38391 --shard-id $SHARD_ID --cuda-devices $GPU_ID --farm-recheck $TIME --coinbase $COINBASE_ADDRESS

• CLUSTER_IP defines the IP for the Quarkchain cluster. If you want to try the one button quick mining, you can use fullnode.quarkchain.io or fullnode2.quarkchain.io.
• --shard-id defines one specify shard to mine. shard id 1, 10001, 20001, 30001, 40001, 50001 are Ethash.
• --cuda-devices defines specify GPUs to mine.
• --farm-recheck defines check interval in milliseconds for changed work. For example 1000.
• --coinbase defines your mining coinbase address. Please use 20 bytes address generated the same way as an Ethereum address.
• -U is for the CUDA GPU and -G is for the AMD GPU.
