Re: [ANN] Bancor | Protocol for Smart-tokens, solving the liquidity problem

when tokens are traded on the exchange relative to BTC, understandable pricing mechanism. is the flagship and the others were compared. Here, we propose the creation of crosscourse. Prices will be based on courses that are on the exchanges? If so , then not all tokens are liquid and the prices of some are very different in the exchanges, will average?

The network will only work with tokens which are received by smart contracts on everyone, crosscourse to zec, litecoin, Dash will not be used? what will happen to the tokens of other platforms different from etherium?

If I understand you're question correctly, you're asking how the inevitable price differences between smart tokens internal prices & their prices on exchanges.

The answer is the same as the solution to price differences between exchanges: arbitrage bots. When there is profit to be made by a difference in price, these bots automatically come and make trades until they've evened out the prices (and so it is no longer profitable).

To be clear: smart tokens' contracts can buy/sell themselves. No second party needed. That is how every single currency on the network can be fully liquid from day one.

Yeah, right, but since you are going to run a fractional reserve, actual liquidity is going to limited by initial supply. For example, at 20% reserve ratio change in supply by a factor of 2 in either direction will change the price by a factor of 4. This will limit the amount of tokens we will actually be able to buy or sell at reasonable price. Liquidity would be really infinite in two cases: either the initial supply is very large; or reserve ratio is close to 1.

Actually, the supply can be (and for most smart tokens, we think it will be) much smaller than 20%. The reason that smart tokens can still be liquid with tiny reserves is that, when you buy/sell a smart token (or its reserve tokens) the price is calculated as if you sold an infinitely large amount of micro transactions that equal the same total amount. For every micro transaction you do, the price for the next goes up (as with every supply/demand system). So if supply were to grow smaller, the price of each smart token would decrease proportionally. The token would stay liquid, it would just decrease in value.

If demand were such that the price is no longer 'reasonable' to enough people, demand would go down and said price would stop rising (or fall, if demand went low enough that there are now more people selling than buying). In other words, the price of a smart token is kept reasonable by the market, like any other freely traded commodity.

A price of your token is a power law of its supply relative to initial supply. You need to have a fairly large initial supply if you don't want the price to raise/drop by crazy amount after each trade, unless your reserve ration is close to 1.

This is true, a deeper market depth (which is a main function of a reserve currency in this type of smart token) makes for less volatility. The market depth on any given exchange is usually <1%, so a 20% market depth can be considered quite large.

I am sorry, but you are comparing apples and herrings here.

You can't have 5 BANCOR issued initially, which is reserved by 1 ETH. If you do this, your token will behave as any illiquid token, a price will be a random number, which varies significantly with every trade of a fraction of ETH. If you run at low reserve ratio, such as 20%, you need to have a huge initial supply, which is much larger than projected daily volume.
