Query whether the public key to verify the node is lost

./lambdacli query tendermint-validator-set | grep Pubkey | grep `./lambda tendermint show-validator`

Query node sync blocks high

./lambdacli status | grep --color latest_block_height

Whether the query section normal to vote

Download lambda-debugtool

wget https://github.com/LambdaIM/lambda-debugtool/releases/download/v0.0.1/lambda-debugtool.tar.gz
tar zxvf lambda-debugtool.tar.gz

Queries original signature public key

./lambdadg show --pubkey `./lambda tendermint show-validator`

Check the latest the height of the block

curl http://localhost:26657/status

Check the latest block out the private key vote in return json api current interface node contains the original signature within precommits

curl http://localhost:26657/block?height=区块高度

When a node on the block double sign, in the last 10,000 blocks of less than 500 block signature will be jail, and deducting a small tbb.

Re-join the consensus network

Initiated unjail message to re-join the consensus network node after the jail to wait for 10 minutes to initiate punishment unjail command

./lambdacli tx slashing unjail --from [your-account-name] --broadcast-mode block

Since lack of mortgage

If the validator does not meet the minimum collateral requirements 666,666,666utbb, pledge needs to be initiated to complement deducted utbb

validator's self delegation less than MinSelf Delegation, cannot be unjailed

Check account does not exist?

The following error occurs, it may be because you have not just started lambda sync to the latest high can block (the log /tmp/lambda.log) to view high block case

[root@zh]# ./lambdacli query account lambda1z66gxs2wlhmkhh3rljtkzk96fqkk7809zb123
