Know pretty much, been meaning to do a post about it tbh, but here goes a brief intro:

Vechain is a supply chain project backed by many world enterprises like PwC (one of the four big world companies) DNV GL, BMW, etc... it's meant to tackle the authenticity of a project, for example you can scan a wine bottle and see if it is a real wine bottle or a counterfeit! It's also going in on the car industry, house industry, etc... check their website, they have pretty cool explanations in there about the sort of things vechain is trying to solve!
The CEO of Vechain is the former CEO or Louis Vitton, they have big investors in like Tim Draper and Jim Breyer! Vechain has REAL connections with the Chinese government! The mainnet was released just a few weeks ago and the token swamp is still going, after it many coins will be locked in master nodes, decreasing the circulating supply!

Vechain is also going to provide a sort of gas coin like NEO does, it's called Thor and everytime you want to verify a product or anything you need to pay that thor, the price of Thor will be stable, the nodes will generate more or less and the thor cost will increase or decrease to make the thor price stable, this makes it so big companies like it more, since it has less volatility! They even got a university doing the numbers to make sure the price was stable! There were no critical bugs in the main net launch... don't know what else to say tbh... PwC is in bed with some of the world's top enterprises, like coca cola, McDonald's, etc... I'm very bullish on this coin, it's also going to allow smart contracts... i even got as far as selling my small positions that were ethereum and NEO to put into it! It's probably the most trustworthy coin going around! With real life partnerships!

The luxury industry is experiencing an unprecedented wave of transformation caused by the Internet and Information Technology.

On the other hand, blockchain has opened new ways for luxury brands to establish a personal connection with consumers, completing the customer experience regardless of multiple sales channels. Customers can claim ownership for the purchase of a new bag and Luxury brands can look forward to owning a digital ledger of ownership pertaining to a unique product.

The auto industry requires sophisticated segregation of duties involving a good number of participants in the collaboration, which results in the slow process of digitalization in this industry. Although the auto industry is a multi-trillion USD market, the collaboration between companies still remains traditional. For instance, in most cases, car maintenance records are still recorded on physical papers to date. VeChain provides one of the most promising solutions to enhance the digitalization and collaboration in the auto industry.
