Official info about, Cosmos https://cosmos.network/intro https://vimeo.com/183530279 https://twitter.com/cosmos_hq https://twitter.com/cosmosvalidator Later i cant edit this post, for that remember for update go to official Cosmos Repo or my web if was deprecated. http://melea.es/cosmos-tuto/ https://github.com/cosmos/cosmos-sdk/tree/master/cmd/gaia/testnets Ok, now you have clear what is Cosmos, and you know is going to be huge, maybe you want to run your node and if you have the skills and the time for be a Validator, try to be one of the list. I am in the list. ![Screenshot from 2018-06-07 01-47-40.png](https://cdn.steemitimages.com/DQmb4vwB1ggCK61eprTVBN7LLa5ZdyErF1i8MBftw552GCr/Screenshot%20from%202018-06-07%2001-47-40.png) If you only want explore your skills you can run your node in home. If your intentions is going to be one day one Validator, rent a server in one data center. The node need high security and 24x7x365 days support. Is not a game, is a serious job. Become a Validator. Have a lot responsabilitis, please red the Fac. https://cosmos.network/validators/faq Are you ready? lest do it. Talking in what you need for build your Own node. Hardware for your Server: 2 Cores 2mb Ram 20 Gb Disc Software Ubuntu 16.04 Can start with one VPS and when the chain grow changed for one dedicated server and more. I recommended for your server Create new sudo user Changed the ssh port from 22 to another port. Block ROOT in ssh active Firewall Open port 46656, 46657, and the port you choice for the SSH. --------------------------------------------------- Now you are connected to your ubuntu server with the new user no like ROOT, and have connected in other port different to 22 if you don't gonna get REKT. ----------------------------------------------------- Ok, Now time to build. First you need install Golang and some tools. sudo apt update sudo apt upgrade -y sudo apt-get install screen vim make wget git wget -c 'https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz' -O go1.10.3.linux-amd64.tar.gz sudo tar -C /usr/local -xzf go1.10.3.linux-amd64.tar.gz sudo rm -Rf go1.10.3.linux-amd64.tar.gz go version The program 'go' is currently not installed.

Here's how you can bond tokens to a testnet validator: gaiacli stake delegate --amount=10steak --address-delegator= --address-validator= --name= --chain-id= While tokens are bonded, they are pooled with all the other bonded tokens in the network. Validators and delegators obtain a percentage of shares that equal their stake in this pool. Unbond Tokens If for any reason the validator misbehaves, or you want to unbond a certain amount of tokens, use this following command. You can unbond a specific amount ofshares(eg:12.1) or all of them (MAX). gaiacli stake unbond --address-delegator= --address-validator= --shares=MAX --name= --chain-id= You can check your balance and your stake delegation to see that the unbonding went through successfully. gaiacli account gaiacli stake delegation --address-delegator= --address-validator= --chain-id= View the validator's information with this command: gaiacli stake validator --address-validator= --chain-id= To check that the validator is active, look for it here: gaiacli advanced tendermint validator-set Congratulations, Now you have your Validator running and need go to Validator Official chat and present yourself and your intentions in the Cosmos Blockchain https://riot.im/app/#/room/#cosmos_validators:matrix.org Remember that it is a testnet network, prior to the launch of the real network. you must be connected to the official chat to be able to make the updates and the necessary changes in your server. The next post will be how to update the software when the new version comes out. Well I hope you can be a good validator fo the Cosmos Blockchain.
