Release mainnet1.6.0
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

python3 quarkchain/cluster/cluster.py --cluster_config <config>
or
./run_cluster.py
Network ID

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 $COINBASE_ADDRESS
CLUSTER_IP
defines the IP for the Quarkchain cluster. If you want to try the one button quick mining, you can use fullnode.quarkchain.io or fullnode2.quarkchain.io.--shard-id
defines one specify shard to mine. shard id 1, 10001, 20001, 30001, 40001, 50001 are Ethash.--cuda-devices
defines specify GPUs to mine.--farm-recheck
defines check interval in milliseconds for changed work. For example 1000.--coinbase
defines your mining coinbase address. Please use 20 bytes address generated the same way as an Ethereum address.-U
is for the CUDA GPU and-G
is for the AMD GPU.
Chain | Shard | Hash Algo | Parameter for Ethminer shard ID |
---|---|---|---|
0 | 0 | Ethash | 1 |
1 | 0 | Ethash | 10001 |
2 | 0 | Ethash | 20001 |
3 | 0 | Ethash | 30001 |
4 | 0 | Ethash | 40001 |
5 | 0 | Ethash | 50001 |
CPU mining shard ID
Instructions for Qkchash CPU mining
./ethminer --farm http://$CLUSTER_IP:38391 --coinbase $COINBASE_ADDRESS -t <n> --shard-id $SHARD_ID
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 60001 and 70001 are Qkchash.--coinbase
defines your mining coinbase address. Please use 20 bytes address generated the same way as an Ethereum address.-t
limits number of CPU miners to n
Chain | Shard | Hash Algo | Parameter for Ethminer shard ID |
---|---|---|---|
6 | 0 | Qkchash | 60001 |
7 | 0 | Qkchash | 70001 |
