Currently there are three stores for the nameservice module. I think we should collapse them into one. This would have the following benefits:

• Mirror current best practices in existing modules
• Add a types.go file to the module for the struct that would contain {value, price, owner}, which would help readers understand its use. They will likely have to have one if they ever build their own module.
• Unmarshalling overhead is ok since we always use at least 2/3 fields of the struct in functions.

when i edit the config file of another node as below:
seeds = "[email protected]:26656"

I start the new node,but errors show:
I[2019-06-28|15:49:16.935] Starting ABCI with Tendermint module=main

how to solve this problem?

I followed the guide, but got error when start

ERROR: error during handshake: error on replay: validator set is nil in genesis and still empty after InitChain

I try to buy-name by using CLI and it works. However, I try to buy-name by using REST API and It doesn't work. The command I used is as follow as below.

curl -XPOST -s -k http://localhost:1317/nameservice/names --data-binary '{"base_req":{"from":"jack","password":"12345678","chain_id":"namechain","sequence":"0","account_number":"0"},"name":"jack1.id","amount":"5nametoken","buyer":"$(nscli keys show jack -a)"}' | jq .

Output:

{
  "error": "invalid from address: jack"
}

Which I run these commands below to init chain.

# Initialize configuration files and genesis file
nsd init --chain-id namechain

# Copy the `Address` output here and save it for later use 
# [optional] add "--ledger" at the end to use a Ledger Nano S 
echo 12345678 | nscli keys add jack

# Copy the `Address` output here and save it for later use
echo 12345678 | nscli keys add alice

# Add both accounts, with coins to the genesis file
nsd add-genesis-account $(nscli keys show jack -a) 1000nametoken,1000jackcoin
nsd add-genesis-account $(nscli keys show alice -a) 1000nametoken,1000alicecoin

Please help advice.

no REST endpoint for accessing all names

After finishing the tutorial, and copy and pasting everything in, I am getting the errors below. Maybe they are due to my own mistakes, but they look like changed apis. Pasting them here before I try to solve them.

How can I see the history of all transactions?

The examples given here: https://github.com/cosmos/sdk-application-tutorial/blob/master/tutorial/run-rest.md

no longer work. If one adjusts the curl commands as posted here:
#76

then the results are unsigned jsons and no working buy-name is broadcasted. It would be nice to adjust the run-rest.md so that a working example is given.

When the nsd blockchain is running, I can go to http://localhost:26657/ to see all the available endpoints.

Is it possible to create a similar user experience when it comes to nscli rest server? providing the user with json-rpc endpoints that can be used to GET account balances, resolve names or send transactions?

If such a feature already exists, could someone point me to it?

Hi, I am trying to make this tutorial work. I followed along with it, but when I try to run 'make install' it give me this error:

and when I try to run 'go build nsd.go' or 'go build nscli.go', I get this error:

If I'm leaving out the ledger import I get a similar error.

This error is reported from the example code in the tutorial.

Should it now be github.com/tendermint/tm-db?

Hi,

Currently I'm developing under sdk-tutorial's guide and there is no dependency setting doc in web tutorial.
https://cosmos.network/docs/tutorial/gomod.html

And it seems to be outdated in github tutorial.
If you don't provide go.mod and install by only go get, the CLI&daemon build fails like cosmos/cosmos-sdk#4179
Please update the doc the latest version :)

Many thanks,
Bryan

When running the tutorial locally, the nscli query nameservice resolve jack.id command doesn't work. I'd tried the same a few days back (before the update to update to sdk 0.37) and it worked then.

$ nscli query nameservice resolve jack.id
could not resolve name - jack.id

This is below command which using run REST Server.
mtcli rest-server --laddr tcp://0.0.0.0:1317 --trust-node

in this tutorial, https://github.com/cosmos/sdk-application-tutorial/blob/master/tutorial/rest.md

where is clientrest.CompleteAndBroadcastTxREST been used?

As the title shows. When I tested running the tutorial,the height of transaction is always 0..

Am I correct to believe that rest server that is started using nscli is meant to roughly mimic gaicli rest server? In particular, should it fully support at least ICS0 Tendermint APIs on this Swagger page?

The API that is missing is /txs/{hash} (Get a Tx by hash). I am able to use this API via gaicli rest server but not via nscli rest server.

Most applications built on the SDK (and certainly a nameservice) will want lite client RPC functionality, I think we should demonstrate a minimum viable example of what that looks like.

Might block on cosmos/cosmos-sdk#1081.

Dependabot couldn't find a go.mod for this project.

Dependabot requires a go.mod to evaluate your project's current Go dependencies. It had expected to find one at the path: /go.mod.

If this isn't a Go project, or if it is a library, you may wish to disable updates for it from within Dependabot.

Cosmos SDK has been upgraded to go.mod
cosmos/cosmos-sdk#3907

But the tutorial still uses dep:
https://github.com/cosmos/sdk-application-tutorial/search?q=dep&unscoped_q=dep

There is a ":" missing on this line

https://github.com/cosmos/sdk-application-tutorial/blob/aa40157c68d5e2d5b22187fdf5c4976e7a917004/x/nameservice/client/cli/tx.go#L36

In the step of creating types for the module it is referenced that the file should be created at ./x/nameservice/types.go but the package is types for the code so it should be noted it is created at ./x/nameservice/types/types.go.

I am assuming this is a typo because in the following step it says "Start by creating a key.go file withing in the types folder" (withing also a typo) and in the example code the files are in that folder.

Currently the tutorial shows only the CLI interactions. We should also show the LCD routes as well.

Just like gaiadebug. It would be nice so that people can query txs bytes from tendermint rpc and then unmarshall them to JSON.

Thanks for running through this with me @okwme! Here are some issues I saw when working

• Update tree on first page
• Explain tendermint on the second page
• formating on page 3
• Capitalize NewnameserviceApp properly
• Add note that codec is explained later on page 3
• keeper.md - sync coin types and figure that out
• handlers.md - add note that you don't need code from interface
• wording at the beginning of SetName.md
• remove notification about NameID and change tutorial
• Maybe think about using sdk.Result in the handler

More to come

What libs and functions in the cosmos-sdk i can use to sign transaction on the frontend (user-appcilation)? Explain please how can i do this on the example of the nameservice (tutor. app)?

Sorry for mis subject, but i cant find answer anywhere :\

Add documentation or update the tutorial to explain how to extend existing keepers and handlers.

Ref: cosmos/cosmos-sdk#4664

Currently the tutorial hand-waves over Genesis file creation and format. We need to add some more information about this. May bock on cosmos/cosmos-sdk#3006 or cosmos/cosmos-sdk#3406

How to create new account without restarting node for this tutorial?

x/nameservice/client/cli/tx.go:94:52: "github.com/cosmos/cosmos-sdk/client/context".NewCLIContext().WithCodec(cdc).WithAccountDecoder undefined (type "github.com/cosmos/cosmos-sdk/client/context".CLIContext has no field or method WithAccountDecoder)
make: *** [install] Error 2

Any ideas? I'm new to the Go toolchain.

Test nameservice create transection with Multithreading which result error and query not found the domain name

How to solve problem?

Can you upgrade tutorial for tx cmd queries? GetCmdSetName and GetCmdBuyName use functions that dont exist after refactoring.

ERROR Sentence: rm -rf~ / .ns *
(如果你之前已经运行过该教程，则可以从头开始使用nsd unsafe-reset-all或删除home文件夹下的两个执行程序的数据及配置文件夹rm -rf~ / .ns *)

Correct Sentence: rm -rf ~/.ns*

Consequence: ALL file in $Home folder have been DELETED !!!!!! BAD STORT!! Please must modify this error immediately! Thanks!

Can we please make sure the tutorial is backward compatible or at least stay up to date.

THIS IS A HUGE BLOCKER FOR PEOPLE TO JOIN THE COSMOS ECOSYSTEM.

Or can we include a verification process that tutorial itself work with the lates ask codebase!?

Hi,

I tried to use this tutorial to make a chain with only one token.

First, I changed bond_denom in genesis.json to tuckeratom.
Then, I gave all of the genesis accounts 1000 tuckeratom.
Finally, I made a gentx using --amount 1000tuckeratom.

I collected the gentx and validated the genesis.json, everything looked normal.
But when I run nsd, I get "ERROR: error during handshake: error on replay: validator set is nil in genesis and still empty after InitChain"

This error does not appear if I use stake as the bond_denom and do the default gentx with 100000000stake.

But if I use stake as the bond_denom, I can't delegate tuckeratoms.

Has non-stake delegation worked for anyone else?

Thanks

$ nsd start
$ nsd stop
$ nsd export

yields

panic: stored supply should not have been nil

Currently we focus on the module first, and then the application. It is true that the module is the main piece that people need to work on, but I think it's important for them to discover first how the app import and handle modules before coding one.

The bulk of the tuto would still be the module, but the narrative would change a bit. Namely, we would have:

• sdk-module-tutorial -> sdk-app-tutorial
• Instead of starting directly with keeper, we would start by an empty ./app.go and then go in the module section when we realise we need it in the process of building app.go
• This would enable devs to have a more gentle introduction to how they can build their state machine and how the sdk manages modules.

Overall it would require little change, and would solidify this tutorial as a coherent, bottom-up and self-sufficient way of learning the sdk.

Summary of Bug

I'm trying to run nameservice CLI application as per the instructions in the tutorial (https://cosmos.network/docs/tutorial/build-run.html#building-the-nameservice-application).

After running the "nscli query nameservice resolve jack.id", I'm getting below error:
"Could not resolve name - jack.id"

Following up on discussion with jin and @jackzampolin yesterday, and upon further thinking, I think it would be good to integrate content from basecoin that is missing from nameservice. The goal would be to keep nameservice concise while also making it self-sufficient.

Ultimately the question is what is the goal of this tutorial. If we take a look at https://doc.rust-lang.org/, we see there are two things:

• Rust book (https://doc.rust-lang.org/book/2018-edition/index.html). It is described as "Affectionately nicknamed "the book," The Rust Programming Language will give you an overview of the language from first principles. You'll build a few projects along the way, and by the end, you'll have a solid grasp of the language.".
• Rust by examples: While the book talks about code with a lot of words, RBE shows off a bunch of code, and keeps the talking to a minimum.

If we want nameservice to become this self-sufficient learn by doing example that introduces all the important concepts of the sdk, and I think we agreed it would be, then it ought to be a bit longer and incorporate important explanations that currently live in basecoin. I think this vision for the nameservice example would also be supported by a slight change in narrative described here: #3.

Do you have any suggestions?

Hi,

I was going through the master branch of sdk-application-tutorial
https://github.com/cosmos/sdk-application-tutorial/blob/master/go.mod

Here the cosmos-sdk version mentioned is v0.28.2-0.20190616100639-18415eedaf25 which is probably a deprecated version. Sometimes go.mod automatically updates it to v0.35.0.

Anyways the main issue here is that none of these version contains the following packages(or atleast either of the packages):
github.com/cosmos/cosmos-sdk/types/module
github.com/cosmos/cosmos-sdk/x/auth/genaccounts

These packages are being imported in app.go. You can find it here:
https://github.com/cosmos/sdk-application-tutorial/blob/master/app.go

I am really confused how the makefile is working in such a scenario when the modules doesn't exist because when i try to do the same thing in my application its throwing error as follows:

cannot load github.com/cosmos/cosmos-sdk/types/module: import lookup disabled by -mod=readonly
Makefile:5: recipe for target 'install' failed
make: *** [install] Error 1

Makefile used by me is same as one here:
https://github.com/cosmos/sdk-application-tutorial/blob/master/Makefile

Please let me know what other changes i should make for the makefile to work. The error that i am getting is expected according to me but its surprising how the same error is not thrown in case of nameservice app. Please let me know of the hack.

I am facing similar errors when i am trying to make changes in gaiacli. Its makefile stops creating binaries on making any change and keeps throwing error until you revert it back to original.

➜  sdk-application-tutorial git:(master) ✗ nsd init --chain-id testchain

ERROR: genesis.json file already exists: /Users/billy/.nsd/config/genesis.json

Not sure if this should be an issue with the SDK about that command or if we should mention this as an outcome in the tutorial.

nscli tx nameservice buy-name jack.id 5000nametoken --from jack

or

nscli tx nameservice buy-name jack.id 5wrgstrftoken --from jack

both respond with

"raw_log": "[{\"msg_index\":0,\"success\":true,\"log\":\"\"}]",
  "logs": [
    {
      "msg_index": 0,
      "success": true,
      "log": ""
    }
  ]

the setup is a fresh install with instructions from tutorial, so 1000nametoken are present for jack. It works with <=1000.
nsd shows 1 invalidtx. but nscli gives the response quoted above.

Maybe this bug is not from sdk-application-tutorial but rather from cosmos-sdk 0.37?

• genesis.go should be split in two -> A genesis.go should be created in /types, it would contain the type definition of GenesisState as well as DefaultGenesis and ValidateGenesis
• Add expected_keepers.go in /types, modify keeper.go accordingly.
