That was a great article! Thanks for the tips. I get only one problem in step 6: Deploying the contract, which I believe has to do with accounts parameter. Isn't it passed automatically when using Ganache, but with public testnet deployment, we need to provide the sender's address, right?

It works fine when I remove accounts, like this:

module.exports = function(deployer) {

deployer.deploy(MyNotary);

};

Please let me know what are your thoughts here, I might be missing something.
