Ink Protocol is developed by Listia, a P2P marketplace for buying and selling used goods online. Launched in 2009, the marketplace now has over 10 million registered users who have exchanged 100 million items. The company has
raised $11MM in venture capital from prominent investors. Listia will be introducing a new decentralized reputation
and payment system called Ink Protocol (“Ink”), which is powered by the Ethereum blockchain and XNK, an ERC20
compatible token. Ink helps users safely send and receive payments in P2P marketplaces while earning public
reputation for every completed transaction. It greatly enhances the buying/selling process with decentralized reputation and feedback ratings, decentralized escrow for secure payments, third party dispute resolution, and very low transaction costs.
Ink can be integrated into new or existing marketplaces and can also be used in marketplaces
that don’t directly handle payments (eg, Craigslist and Facebook Marketplace). For sellers,
accepting Ink builds up their public reputation, which allows them to start selling quickly on new
marketplaces without needing to build reputation from scratch. Buyers can view any seller’s
reputation across multiple marketplaces and confidently pay using either automated or
human-mediated escrow contracts. Payments can be made and received natively using the Ink
Protocol Token (XNK) or converted easily to and from fiat currencies like USD.
Ink will also become the new reputation and payment system within the Listia marketplace.
Listia currently uses a centralized virtual currency called Listia Credits for all transactions.
Existing users with Listia Credits will have their balances converted to XNK, providing Ink with a
tremendous boost for initial usage, stability, and network effects on day one. Additionally, Listia
will create a standalone payments app so users of local marketplaces such as Craigslist and
Facebook Marketplace can build reputation and start using Ink right away. With large scale
adoption and apps that can be used in multiple marketplaces at launch, Ink is well situated to
become the preferred reputation and payment system in all P2P marketplace transactions.
