EOS tutorial: How to upload the 'Hello World' smart contract

How to publish smart contracts on EOS

In this tutorial, you will learn how to start an EOS blockchain node on your computer, create a wallet and import keys, open an account, upload the 'hello' contract, and write to it on the blockchain. This tutorial is geared towards beginners just learning how to become blockchain developers.

Here's my screen log so you can follow along.

Open a node to start writing blocks on your own computer:

$ nodeos -e -p eosio --delete-all-blocks --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin

Run the following commands in a new terminal window.

$ cleos wallet list
$ cleos wallet unlock -n eos-key
$ cleos wallet list
$ cleos create key
$ cleos create key
$ cleos wallet create -n myaccount3
$ cleos wallet import -n myaccount3 PRIVATEKEY1
$ cleos wallet import -n myaccount3 PRIVATEKEY2
$ cleos wallet list keys
$ cleos create account eosio myaccount3 EOS63q35uwVA8wCayPaA3cWWJhxz2atkuYqTAhRvYrejvEYm4Lb9Z EOS5yzvWZHopaG7RXDMuVEbgPuiaiiWtLT59b9Uv55E7oghqpiRHW
$ cleos get account myaccount3
$ cleos set contract myaccount3 ~/eos/build/contracts/hello
$ cleos push action myaccount3 hi '["powderskier"]' -p myaccount3
$ cleos get block 1278
