In North America, there are FICO scoring standards for consumer credit. In China, we have sesame credit. However, these scoring systems are only targeted at the user's financial situation and have a certain horizontal expansion boundary. There is now a scoring system for the sharing economy that provides a measure of the user's daily behavior. Compared with FICO, it is more instructive and relevant to the sharing economy. This is the PIN reputation scoring system. This time, Golden Finance was fortunate enough to interview Euwyn, the founder of the PIN project, who introduced some of the thoughts that PIN has produced from concept generation to practical application. Euwyn graduated from Cornell University with a degree in Computer Science and a law degree. In 2010, he entered the famous American incubator Y Combinator. The first company was founded by Uber's first investor, First Round Capital. Later, he founded a bitcoin leveraged trading platform called Delta, which was invested by the Winklevoss brothers and IniTIalized Capital. Launched the SPIN project in 2017 and received investment from prominent individuals such as Y Combinator partner Grishin RoboTIcs, China Rock and Quora co-founder Charlie Cheever. Euwyn said that PIN solves the most "headache" problem for sharing economy providers, and that is the user's trust. At present, almost all sharing economy providers “have to have a certain degree of trust in users, but this will inevitably lead to irresponsible phenomena. Take shared bicycles as an example. If you don't care for bicycles or even destroy bicycles, it is not uncommon for them to be placed in a designated position or even locked for "private use of buses" after use. Therefore, the team believes that the establishment of a comprehensive user credit system, in addition to reducing the loss of the sharing economy provider, can also stimulate users to perform better. Euwyn joined the shared economy industry in 2008 as the founder and CTO of a vacation rental platform. He told Golden Finance that the concept of PIN "has been there at the beginning." Euwyn said: “I was an early investor in the blockchain sector in 2014. The founders of Spin and Pin Protocol have known for many years, and at the end of last year we finalized the concept of PIN and wrote a white paper ourselves.†“By using the blockchain, we implemented the PIN as a centralized protocol to create a neutral platform that supports multiple shared economy providers.†Euwyn explained that PIN is a reputation protocol, a company on the PIN network. The user's reputation is scored, and the PIN token is issued for each increased reputation score to achieve the effect of motivating the user. The arbitration and voting mechanism is built into the PIN protocol and belongs to the agreement managed by the community. The voting mechanism is a key part of the agreement and can help the community to continuously improve and drive PIN changes. This includes improving the reputation score agreement and accepting new sharing economy companies into the PIN network. And, Euwyn said, the arbitration mechanism can also use the community to resolve any disputes that arise from a particular user's change in reputation scores. According to Euwyn, PIN is part of the Spin team's project, but has an independent entity operation with the goal of building an autonomous community. But because Spin's shared bicycle network is an important user acquisition channel, Spin's existing and ever-increasing number of users is also the biggest advantage of PIN. Euwyn said that from Europe to Asia to the United States, PIN has received enthusiastic attention and acceptance. “PIN has a world-class team dedicated to introducing partner companies from different industries into the PIN agreement. In addition, we believe that citing users through the PIN protocol will help solve the problem of oversupply and confusion. †Shared bikes represent only the first application of the PIN protocol, and Euwyn said the team believes that PINs are suitable for the entire sharing economy, whether it's cycling, apartments, batteries or other future shared areas. Euwyn revealed to Golden Finance that the team is currently in close and in-depth discussions with a number of shared economic suppliers, including a global shared bus company. PIN plans to launch the agreement by the end of 201 and integrate it with other vendors into the Spin platform. “We have seen the changes that the sharing economy has brought to the hotel and transportation sectors, and we have reason to believe that its impact will extend to all aspects of our daily lives.†Attachment: Project investor information * Chandler Guo - Blockchain investors (Ethereum, NEO, Qtum, Binance, Huobi, Gate.io) once managed one of the world's largest bitcoin mining companies. * Kenzi Wang - Block Partner AU21 General Partner. * Josh Fraser - co-founder of Origin Protocol. * Matthew Liu - Co-founder of Origin Protocol. * Gee Chuang - co-founder of Ink Protocol and LisTIa. * David Chen, a former partner at Lightspeed. * Michael Ma - General Partner of Liquid 2 Ventures. * Dmitry Grishin - co-founder of Grishin RoboTIcs, Mail.ru (DST), one of the largest Internet companies in Russia. * AU21 - blockchain fund from Chandler Guo and Kenzi Wang. * Badwater Capital - blockchain consultants and investors, supporters of Red Pulse, APEX, Trinity, NEX, IHT, Vechain, Hydro, Spacechain, Beetoken, Alphacat and DreamTeam. * Liquid 2 Ventures - a venture capital firm consisting of Joe Montana, Michael Ma and Mike Miller.
