Disclaimer

This release involves consensus changes (explained below). To avoid wasting mining power, please upgrade the cluster to this release before Thursday, April 30, 2020 17:00:00 AM GMT-07:00 DST.

Updates

  • * Enables native token auction system contract (QCEP-005) and adds minting pre-compiled contract for auctioning / issuing new native tokens
  • * Enables native token gas exchange system contract (QCEP-006) and updates EVM accordingly to support paying native tokens as transaction fees
  • * Adds pre-compiled contracts to support querying native token balance in smart contracts
  • * Reduces PoSW staking requirements on shard chains with the same rate as coinbase reward reduction (i.e. 0.88x) after each epoch ends
  • Migrates CHAIN_MASK_LIST to FULL_SHARD_ID_LIST configuration values while being backward-compatible for older configuration files
  • Various small fixes and improvements

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

Minor Changes

Comparing with 1.4.1, this version can derive necessary consensus config changes if running for mainnet, thus users don't have to update their customized configs after upgrading the container or checking out this tagged version of code.

Native Token Auction

For details, please refer to QCEP-005.

Native Token Gas Exchange

For details, please refer to QCEP-006.

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
