clique-v4

Update: 2019/1/30 , re-release with new goerli chain spec.
Update: 2019/1/29 , re-release with timestamp check fix.

clique-v4 with both validating & sealing:

example command to seal on an local chain:

target/debug/parity --chain /tmp/1.json account new

first create an account with password , then store password in password file, use following command to seal on an local chain.

target/debug/parity --chain /tmp/1.json -l engine=trace,miner=trace --force-sealing --reseal-min-period=1000 --reseal-max-period=1000 --engine-signer=0x673c228d04def98e373a504339b47c7005164c39 --password /tmp/1

Sync goerli + seal works too, however you need to be in the signer list to sign real blocks.

target/debug/parity --chain goerli -l engine=trace,miner=trace --reseal-min-period=1000 --reseal-max-period=1000 --engine-signer=0x9a66a7d5162074a0899edf2d344f1f1fd6981869 --passw
ord /tmp/1
