Hi, I'm creating a new ERC20 token (END) with the following economic model:

Every Bitcoin transaction can be sent with memo text in an OP_RET output. This memo can be used to promote user brand in everyday transactions.
The Endurio Protocol is designed to create an incentive for Bitcoin users to include a small memo into their everyday transactions to promote any brand paid in the market.

To mine "SomeBrand" is to:
1. send a Bitcoin transaction with the first OP_RET data begins with “SomeBrand”, and wait for a confirmation,
2. relay that transaction to the Endurio contract on the Ethereum network.

END Token Economic:

• END’s initial supply is ZERO. No token is pre-mined. No ICO.
• END is freshly mined only by successful mining "endur.io"
• In the Brand Market:
  
  • END is required to fund user brand campaign
  • END is paid by campaigns to the miners mining user brand
• In the Referral Network:
  
  • END is burnt to pay for rent.
  • END is paid as a commission for each successful mining.

Details document is here (temporary): https://endur.io

I just finished the contract code and unit-tests, waiting for the security audit. I'm starting to code a simple web-miner, where anyone can start mining using MetaMask, ezDeFi, etc.
