Thank you very much for your guidance on this. Your article, combined with weeks of research and planning went into the creation of this #Whitepaper and #FOSS example I developed

Here’s how to accept #Ether and #ERC20 Tokens as Payment from customers that you can authenticate and verify using nothing more than #DigitalSignatures. It’s now possible to do it in a very user friendly way.

I built the example using Angular, TruffleBoxes, OpenZeppelin, EthJS, MetaMask, Eth-Sig-Util. The future will be #decentralized.
