Exploring direct payments

What are the use cases?

In-person

Remotely

Wallet servers

The current servers

  • They provide us with the header when a new block is mined.
  • They provide us with notification that payments within transactions arrive on our addresses.
  • They provide us with transactions and the merkle proofs for those transactions, so that the transactions can be verified based on proof of work.

Current expectations of future needs

Paying for server access

Do you really trust this to not be stealing your keys?

How users might connect via the servers

Payments without servers

  • Allows two users to establish communication.
  • Allows two users who directly communication, to do so reliably.
  • Working out how a desktop wallet might operate as a NFC-based merchant payments solution. Are there NFC USB dongles?
  • Working out user friendly UI and protocols for detecting ability to directly connect over local or internet IPv4 or IPv6 addresses. And how the two wallets tell each other their addresses to begin with, so that they can know where to connect.

Loose ends

Using the blockchain for communication

The offline edge case

Do our servers need to support Paymail to monetise?
