Ink Protocol

Decentralized reputation and payments for peer-to-peer marketplaces.


Decentralized reputation and feedback

Ink Protocol helps users safely send and receive payments in P2P marketplaces while earning public reputation for every completed transaction.

Sellers can take their earned reputation with them from marketplace to marketplace.

To ensure sellers’ reputations are credible, feedback may only be given on completed transactions.

Third party mediation and escrow

Ink Protocol’s built-in dispute resolution allows a mediator to be assigned to a transaction. Mediators exist as independent Smart Contracts and are jointly agreed upon by the buyer and seller.

With mediation, payment is held in escrow until the buyer confirms the transaction. In the event of a dispute, the mediator works with both parties to decide on an outcome.
