Update for latest testnet.

No instructions have been added here. Suggest we remove if it is not a good relayer solution. Hermes seems to have become the defacto relayer.

We need to improve the default page either:

• with a nice description of juno and a couple of links to groups to get started, or
• keep the way it is and update all the page links.

It seems like keeping it in this format will make it difficult to maintain.

The docs suggest that running junod tx wasm store ... will give some JSON output from which the code ID of the contract can be extracted. Walking through the commands in those docs though the output looks like yaml:

gas estimate: 1836558
code: 0
codespace: ""
data: ""
gas_used: "0"
gas_wanted: "0"
height: "0"
info: ""
logs: []
raw_log: '[]'
timestamp: ""
tx: null
txhash: 1405DEEA2C3947526B265FDD199578A7377143FAB397C034A953E1866B06FEF6

I can then get the code ID by running junod query tx <txhash> and looking at the raw_log field.

Is this the expected way to go about this now? If it is I can open a PR to update the docs.

My junod config:

$ junod version                                                        
v2.0.0-alpha.1
$ junod config 
{
	"chain-id": "",
	"keyring-backend": "os",
	"output": "text",
	"node": "https://rpc.uni.junomint.com:443/",
	"broadcast-mode": "sync"
}

Many changes to Juno modules. Need to capture cli reference.

wasm
authz
etc? can someone help list.

@faddat

First, find the location of the binary you want to use:

which junod

Then use the path returned to copy it to the directory Cosmovisor expects. Let's assume the previous command returned /home/your-user/go/bin/junod:

cp $HOME/go/bin/junod $DAEMON_HOME/cosmovisor/genesis/bin

cp $HOME/go/bin/junod $DAEMON_HOME/cosmovisor/genesis/bin

The above data is obtained from docs/validators/setting-up-cosmovisor.md there we can see the cp junod instruction is duplicated.

Needs to include information for:
a) syncing from genesis to current block.
b) syncing from snapshot.

Statesync still not viable for public without wasm folder solution.

Following this tutorial from install to this point, was unaware of how to setup keys, will search deeper.

Update delegations handbook with new dates, any other changes required.

Queries / getting data

• query etc of a contract state (including past state with rest? and can do with RPC/CosmJS?)
• Link to https://interchainacademy.cosmos.network/tutorials/6-cosmjs/2-first-steps.html
• subscribe to Tendermint

# python example from my CosmosCache repo. Then these links show GOLang
You can subscribe to a query via the RPC websocket

• show mintscan.io of seeing contract data / information. (Include screenshots)

Misc

How keyring-backend works with CLI (test, os) many have issues with this
How to get all votes from a proposal? (Link cosmoscontracts repo but embed code directly)
How does gas work?

Explain gas = amount of compuate
Most networks in cosmos charge 0.0025ujuno per gas
So if you use 1,000,000 gas, it cost 0.0025*1000000 = 2500ujuno
Some validators may only allow a higher rate to ensure no spam transaction get though, so you may want to set the gas price to be more like 0.003 or 0.004 to be safe

Authz - grant voting example

# https://github.com/cosmos/cosmos-sdk/blob/main/proto/cosmos/gov/v1beta1/tx.proto
junod tx authz grant <new_address> generic --msg-type=/cosmos.gov.v1beta1.MsgVote --from validator
junod tx authz exec <(junod tx vote withdraw-rewards <valoper> -y --from <validator_bech32_address> --generate-only) --from grantedWallet -y
junod tx authz exec <(junod tx gov vote 202 yes -y --from juno1t8ehvswxjfn3ejzkjtntcyrqwvmvuknzy3ajxy --generate-only)> --from juno1 -y

Contracts

• How do I store a list in a contract and each unique address can add a name to it by calling a function, and can override their own one.
• How can I query this list in the contract and get the stored name by supplying the unique address.
• how do I check if a change has been made on a contract? must I do a call every time period?
• how do I check if a change has been made on a list within a contract? must I do a call every time period?
