Three Technical Requirements to Connect Blockchains Without a Token

"Since I see a lot of downsides to having one large uber-blockchain connecting all others, I will focus on a token-LESS solution. This would have several advantages:

No need for an additional token.

Users can “remain” on their blockchain.

No need to trust a centralized third party.

There are a couple of downsides to such an approach however. Since there is no uber-blockchain or a centralized party ensuring the connection, there needs to be enough liquidity between two blockchains to be connected. If I want to transfer funds from the Ethereum to the Bitcoin blockchain, for example, I need someone who, at the same time, wants to go from bitcoin to ether. For these two large blockchains, you will always find someone willing to go in either direction, but what about from Ethereum to a smaller blockchain or a small blockchain to another small blockchain? While I will be laying out a way on how that could even be solved, I want to stress that liquidity is the key economic factor in such a cryptographically secure multi-asset network."
