tendermint | ⟁ Tendermint Core in Go | Cryptography library

I am trying to generate hd wallet private keys , public keys and addresess using cosmos sdk. Below is the equivalent implementation in python which generates the keys , address as expected but when trying to generated in golang using cosmos sdk it won't generate same keys. Any inputs for equivalent golang version of the python implementation is much appreciated. Thank you.

I need Tendermint in one of my projects but have never used it before so I am trying to implement a very simple example from here first: https://docs.tendermint.com/master/tutorials/java.html but in C# (.NET 5.0).

(Download: Minimal Example)

I have created a simple GRPC Service trying to follow the guide as closely as possible:

Startup.cs:

Im am running a Tendermint HTTP RPC server at port 26657 on docker container using ubuntu image.

docker run -itd --name t1 -p 26657:26657 tendermint

When I perform a curl operaion inside the container, i get the JSON reponse from the RPC server.

docker exec -it t1 curl localhost:26657/status

But when it try to use the curl operation on the host, then i get an error: "curl: (52) Empty reply from server"

curl localhost:26657/status

Initially I was running docker on a Windows machine. I thought there might be some issue with windows not able to talk with WSL Linux (which docker uses in Windows for ubuntu). So, I tried the same commands in a Linux Virtual Box running Ubuntu 20.04. Still the host ubuntu is not able to access the container server using curl/web browser.

I tried running a apache2 server at port 80 inside container and mapped to port 5000 (-p 5000:80). This worked and I was able to access the apache2 at localhost:5000 in the host. When I try to map 26657 to 5000 (-p 5000:26657) on the RPC server then the same issue happens. So the issue is only with ports other than port 80 in the container.

I tried "netstat -an" on the host machine and it says:"TCP 0.0.0.0:26657 0.0.0.0:0 LISTENING".

Tried running a simple Angular 11 HTTP lite server running at 4200 and mapped to host 4200. It was not able to map this port as well.

Also tried to telnet into port 26657 on host and was able to connect successfully using "telnet localhost 26657". When the container is terminated, then the telnet fails to connect which is ideal. But still not able to connect host using curl/web brower and get the JSON response from the container.

I just tried to run the tendermint RPC server on an Amazon EC2 instance. I was not able to access the port 26657 using the public IP. I guess there is something to do with the protocol on the 26657 port.

I have been trying to get this text color to be white rather than black so it can be more readable on our site. Unfortunately I have been unsuccessful in changing it. Im not sure what I am missing lol im sure its right in front of me though. I did go through a website to embed this as well.

I have a workflow that executes a bunch of fuzz tests and, at the end, calculates the total number of files in all crashers sub-directories. Later, in another job, I use that number to send a notification to Slack. But, for some reason, ::set-output produces no output and, most importantly, the next job does not get run even though the number of crashers is not zero!

I'm trying to go through the "Running a node" tutorial here: https://github.com/cosmos/cosmos-sdk/blob/master/docs/run-node/run-node.md

I seem to have some issue though, the genesis transactions don't manage to set up a validator, so the validator set is empty and the app stops. Am I missing something?

I'm running script.sh and getting error message in error.log

Keplr just added the feature to import an account using a private key (which is awesome!). This was primarily requested because a number of lunie users lost their mnemonic phrases but maintained their access to lunie itself. That meant lunie could export a private key but not the mnemonic itself. It may also be userful for future Ethermint users who want to migrate from metamask (which also provides the ability to export and import private keys).

The keys command in the Cosmos SDK CLI also allows a user to export a private key, however I'm unsure how to convert a key from that format into one that could be imported in keplr. The CLI command is as follows:

I have created a blockchain with Starport (https://github.com/tendermint/starport).

The command to install I used was starport app github.com/tosch110/stargateapp --sdk-version=stargate

Now trying to run starport serve and start my blockchain, I get
