9 June, at 0100 UTC, the EOS Mainnet Launch Group voted “Go” to start EOS Mainnet Launch.

EOS is young, and most of the environments are just developing, but some necessary things are available and … work!

If you have actual EOS account, kindly skip this article.

We oriented on education session step by step 15 minutes instructions.

1. Develop blockchain “Trusted Diploma” verification system in 15 minutes. Step by step instruction

2. Developing pirates “Black Label” voting system. Blockchain Smart Contract on Solidity.

Important. Its education guide don’t use it for real money transfers!

Create key pair

We will create a key pair without a wallet.

The most common solution is the command line tool. But we are lazy.

  • Go to link

EOS Key Generation_Edit description_nadejde.github.io

  • Click Register EOS key

Please back up the private key displayed below in multiple safe locations before continuing.

You should make more than one copy (including for external storage device such as a USB stick) and keep all copies in separate secure locations.

  • Click Register EOS key

My example :

Public keyEOS7epiMwQShVAYS6py3SrrJJbuCnbmhN9C6USYnMKBxJPYkydBcZ

Private key5Jqnrmm9qmRMx6yMXTEgQ4N5WZsqGgEP5mi8VjS1hD7sFzTMoZt

NOTE: I CAN SHARE MY PRIVATE KEY ONLY FOR TESTLAB. ANYBODY CAN TRANSFER MONEY FROM YOUR ACCOUNT

There is no way to recover your private key. You must save it right now, or you will be unable to access your EOS tokens

Create account in Jungle Testnet:

  • Go to Testnet website monitor :

Jungle EOS Network Monitor (CryptoLions.io)_EOS Network Monitor. By CryptoLions.io_dev.cryptolions.io

You have to create the account on an EOS Blockchain:

  • Click Create Account

Follow the instructions:

  • Input your preferred account name and copy the public key from the key pair as “Owner Public Key”
  • Copy the same public key from the key pair as “Active Public Key”
  • Check that network answer is like this:

From The Repository

  • Clone repository
  • on a Windows system you will need to run npm install --global --production windows-build-tools
  • npm install to get dependencies
  • copy the .env.example file to .env
  • npm start to compile a build folder.

Installing dev build into Chrome

  • Open up Chrome and type chrome://extensions/ into the url bar
  • Click the Load unpacked extension... button and point it at the folder you just created/built (the folder should have a manifest.json inside of it).

Congratulation, you are primary EOS blockchain user ❤

Summary

I can say that EOS design is more user-friendly than Ethereum:

  • accounts name vs. public key
  • readable message in transaction body vs. only HEX format (hello SPAM)

The environment is very young and will be developed. But you can run all basic functionality without geek command line.

If you require instructions for EOS main net, please comment article

Thanks a lot! Don’t forget you can clap up to 50 times! ❤
