I have looked at colored coins, sidechains and alt-coins and it appears that all of these 'enhancements' just re-invent the concept of a bitcoin token. Why, I asked my self, do we need a new token/altcoin when we have tokens already in Bitcoin?

Making a new token just appeared to complicate the usage of these new 'enhancements' in many ways (i.e. you need to convert BTC into some other token coin, then manage that other coin token etc).

I think I have a working theory on how a blockchain can be created that does not include a new token/altcoin. But I do not think it is possible that I am the first person to think along these lines?

Thus does anyone know of another altcoin/coloredcoin/sidechain theory that does not introduce a new token for the new blockchain? Any pointer appreciated.
