BlocMail addresses the issue of spam email.

… a simple, permission-based system of accepting email.

Each component in the eco-system references the BlocMail ledger to determine whether a message should be accepted, and what any associated cost would be.


  • Ledger nodes – a commission-based, coin-driven platform to incentivise node operators (similar to Ethereum gas)
  • Senders – would offer coin to have message delivered
  • Recipients – maintain a black-list and white-list. recipients receive coin in return for accepting unsolicited email

High-level design proposal

  • Blockchain ledger to hold preferences
  • Website/apps to manage the ledger
  • MTA plugins / extensions
  • Email client plugins / extensions
