Hi folks, I’m one of the contributors at Kong — https://kong.cash/ . Kong is a physical cryptocurrency that looks, feels and works like traditional cash. You can think of it as an ultra-secure, time locked cryptocurrency wallet with a fixed face value — no one can access the token except for the holder of the note after a period of several years. It consists of a secure element and NFC chips mounted on a flexible PCB…

After I buy a grilled cheese sandwich with Kong, how do I handle my taxes? It makes every transaction have possible capital-gains tax implications. The taxation difficulty is the single biggest reason why I stopped making small transactions with Bitcoin. The paperwork, come April, was awful.

It should be just like normal, non-blockchain backed currency, should it not?

This is due to how cryptocurrencies are classified by the IRS. Currently, they are classed as assets (property) as opposed to currencies, and thus any "realized gains" are taxable events. This includes the above example, where you may have technically "realized a gain" while buying a grilled cheese with Bitcoin.

Current cash instruments are centralized.

Hmmmm and where do you get the machinery to create said Kong bills? Seems more convoluted than connecting a gaming pc to a network (please don’t say bitcoin can’t do that now, you could initially)

I don't buy the argument that it's "turtles all the way down". Trust begins and ends at the chip level. I think its possible to make an open root of trust chip better than any solution on the market available today. I think the chips available on the market today are good enough for this specific application but not others.

Also, why not apply this to an existing coin, like Bitcoin, rather than inventing yet another freaking asset? Oh yeah, because then the founders can't get rich in the ICO. Yuck.

There is no ICO. There is no token sale. Bitcoin script does not give us enough operations to do the validation. Using the EVM was the next best candidate. We're selling an extremely limited number of packs to validate the concept and cover manufacturing costs. Section 4.1 of the paper goes into details of why a purpose built token is more suitable than one designed for other purposes[1]. [1] https://ipfs.io/ipfs/QmR…

Wonderful to hear! Thank you for responding to my fear with the light of information.

You're converting me into a fan.

The point of this I thought is to unify the virtual system with a physical product, in the pretty cash. So it isn’t just the chip now, is it? Otherwise why not just... use a hardware wallet and use bitcoin ?

I do agree that people can’t picture or visualize in their mind a “bitcoin”, and so this solves that part. But then you’re left with the, how do people print this tangible pretty currency part.

This is a fantastic project and great idea! One thing, I believe there are 2 hurdles to adoption: Kong - the unit of account/currency and Kong - the paper money. Don't you think you're trying to do 2 things at once? Why not try this unique technology with Dai or Tether which has a lot of traction? In fact, I would LOVE to have Dai bills.

I've been working in crypto for 10 years (well, the only "crypto" that existed back then was Bitcoin) and I agree with zelly's criticism. Another simple flaw of Kong is that when I receive a Kong note, someone could have intentionally fried it with, for example, high voltage on the I2C contacts to damage the secure element without leaving any visible defects. So I need to verify each Kong note I receive by reading th…

"Another simple flaw of Kong is that when I receive a Kong note, someone could have intentionally fried it with, for example, high voltage on the I2C contacts to damage the secure element without leaving any visible defects." That would "fry" the secure element chip entirely, thus destroying it precluding anyone from accessing the token in the future (NFC would fail as well).

Right but asking people to verify every single note they receive is a regression in usability. It also makes the notes less reliable to store than a gold coin or a paper note, which can't be damaged by things like water, high-voltage or microwaves.

The world is moving towards cashless/mobile payments (albeit with the U.S. strangely behind), so why do you feel physical cryptocurrency is a step in the right direction? Do you expect Kong to face greater challenges for adoption (compared to other cryptocurrencies) since it needs a higher critical mass of users?

In the paper, they note that 77% of all transactions globally are still done using cash.

If you're handing off physically then just use cash. How is this any better? The exit to real currency will always reveal Kong transactions at some point. Real cash is more anonymous because it's seamlessly transacted everywhere.

Current cash instruments are centralized.

For producing new bills? Why does that matter? What do you think will happen if anyone can create new bills?
