【cosmos-sdk-笔记】修改各模块的运行参数

这一篇整理了如何修改运行中的链的配置参数。

1.sdk 版本选择

我刚开始测试的时候使用的是 v0.47.3。
但是用 ignite 测试 relayer 的跨链时有问题。
所以特意降到 v0.46.6 写了测试项目了。

结果因为这个版本，这次害我不浅…ㅠㅠ
为了就这么个一个修改voting_period，折腾了2天了，哎～

先说结论：
v0.46.6版本的， tx gov draft-proposal 方法里没有 /cosmos.gov.v1.MsgUpdateParams 方法。
而且网上的都是老资料，很容易误导人。
新版本都没有 change-param 这个命令了…^^;;

    /cosmos.feegrant.v1beta1.MsgRevokeAllowance
    /cosmos.gov.v1.MsgDeposit
    /cosmos.gov.v1.MsgExecLegacyContent
    /cosmos.gov.v1.MsgSubmitProposal
    /cosmos.gov.v1.MsgVote
    /cosmos.gov.v1.MsgVoteWeighted
    /cosmos.gov.v1beta1.MsgDeposit
    /cosmos.gov.v1beta1.MsgSubmitProposal
    /cosmos.gov.v1beta1.MsgVote
    /cosmos.gov.v1beta1.MsgVoteWeighted
↓ ▸ /cosmos.group.v1.MsgCreateGroup

后来我在discord里提问，有个开发给我解答说要用/cosmos.gov.v1.MsgUpdateParams
这才我想到改用别的版本试一试。
改到最新 v0.47.4 版本以后，就可以看到/cosmos.gov.v1.MsgUpdateParams方法了. 哎～

2.配置环境

start.sh

#!/bin/bash
rm -rf ~/.mingxie

export DAEMON_NAME=mingxied
export DAEMON_HOME=$HOME/.mingxie
export DAEMON_RESTART_AFTER_UPGRADE=true

./mingxied config chain-id test
./mingxied config keyring-backend test
./mingxied config broadcast-mode sync
./mingxied init test --chain-id test --overwrite

cat <<< $(jq '.app_state.gov.params.voting_period = "20s"' $HOME/.mingxie/config/genesis.json) > $HOME/.mingxie/config/genesis.json
cat <<< $(jq '.app_state.gov.params.max_deposit_period = "30s"' $HOME/.mingxie/config/genesis.json) > $HOME/.mingxie/config/genesis.json

./mingxied keys add validator1 
./mingxied genesis add-genesis-account validator1 1000000000stake --keyring-backend test 
./mingxied genesis gentx validator1 1000000stake --chain-id test 
./mingxied genesis collect-gentxs


mkdir -p $DAEMON_HOME/cosmovisor/genesis/bin
cp ./mingxied $DAEMON_HOME/cosmovisor/genesis/bin

cosmovisor run start

3.修改配置参数

先查看voting_period是多少？

./mingxied query gov param voting
voting_period: "20000000000"

proposal.json

{
    "messages": [
        {
            "@type": "/cosmos.gov.v1.MsgUpdateParams",
            "authority": "cosmos10d07y265gmmuvt4z0w9aw880jnsr700j6zn9kn",
            "params": {
                "min_deposit": [
                    {
                        "denom": "stake",
                        "amount": "10000000"
                    }
                ],
                "max_deposit_period": "30s",
                "voting_period": "40s",
                "quorum": "0.334000000000000000",
                "threshold": "0.500000000000000000",
                "veto_threshold": "0.334000000000000000",
                "min_initial_deposit_ratio": "0.000000000000000000",
                "burn_vote_quorum": false,
                "burn_proposal_deposit_prevote": false,
                "burn_vote_veto": true
            }
        }
    ],
    "metadata": "ipfs://CID",
    "deposit": "3333stake",
    "title": "update voting_period 40s",
    "summary": "ok"
}

update.sh


#!/bin/bash

./simd tx gov submit-proposal proposal.json --from validator1 --keyring-backend test -y

sleep 6s

./simd tx gov deposit 1 100000000stake --from validator1 --yes

sleep 6s

./simd tx gov vote 1 yes --from validator1 --yes 

sleep 6s

./simd query gov proposal 1

查看结果，已改好了～

./simd query gov param voting
voting_period: "40000000000"
