About Ink Protocol

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 is introducing a new decentralized reputation and payment system called Ink Protocol, which is powered by the Ethereum blockchain and XNK, an ERC20 compatible token. Ink Protocol 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 Protocol 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. XNK will be the new currency on the Listia marketplace at launch.


Ink Protocol can be integrated into new or existing marketplaces and can also be used in marketplaces that don’t directly handle payments.

Ink Protocol doesn’t require a marketplace. It can be used for any peer-to-peer transaction.

Ink Protocol Reviews


Ink Protocol has a vast growing potential even though it already has 10 million registered users using it with Listia. Sellers will find it easier to integrate into other marketplaces due to its feedback and reputation system once other peer to peer markets such as Craigslist, Facebook marketplace and Gumtree catch on to the platform, Ink can turn from millions to billions of users within the years to come.

Decentralised feedback/reputation with third party dispute resolution
Already used by Listia and easily integrated into other p2p markets
Payments can be made using XNK and easily converted into fiat currencies
No/low transaction fees
Ink app is still yet to be established with many p2p markets which don’t usually handle direct payments

News, reviews

While the Ink Protocol ICO certainly faces some real challenges ahead, the team behind the project already have one successful project behind them. The biggest uncertainty revolves around the question of mass adoption. At the same time, however, an already existing product assures at least a minimum user base from the start. After taking all factors into consideration, we’ll be making a small bet on the Ink Protocol ICO.

Listia is an established platform with 10 million registered user and is backed by reputable VCs. This shows the experience and capability of the team.
The token model makes sense. We believe the switch from Listia credit to XNK token would be smooth and not impact the user experience at all.
Since Listia will implement the use of XNK tokens soon after the end of ICO, there will be immediately traction with the usage of tokens. This is different from most other ICOs that will not be able to launch their platform until 3-12 months after ICO.

From the public information that we gather (app ranking history, website traffic, the co-founder admitting that Listia’s growth is not as fast as everyone wanted), and last fund raising round being four years ago), we believe Listia is not a growing business. Since the switch to XNK token does not dramatically change the business model of Listia, we are not sure if the ICO will help Listia’s growth.
It is less than 2 weeks before presale begins and the future roadmap of the project is not released yet. We cannot analyze the soundness of the roadmap and level of planning of the team in executing its vision.

Overall, we like the short-term potential but are neutral about the long-term potential for this ICO. Our thoughts of the tokens for short term and long term are as follows:
For ​short-term holding:
Good. With a hard cap of $15 million ($3.5 million already sold), solid team and high market awareness, we believe the project can be sold out with unmet demand.
Seeing (1) the high market demand for participating in ICOs, (2) a few high profile ICOs canceling due to raising enough funding from presale, and (3) there is a disconnect between the hard cap of ICOs and market cap of existing competing projects, we believe that the days of sub-$20 million solid ICOs are limited until the next correction arrives.
For long-term holding:
Neutral. We are not sure how successful and profitable Listia is given the various information we gathered. The utilization of cryptocurrency does not dramatically change and improve the business model of Listia, so we are neutral about the benefits that the adoption of blockchain has on Listia.
