Cross-chain liquidity

### Inter-Blockchain Collaboration

I find Inter-Blockchain Communication a complete game changer.

The whole ecosystem is evolving faster than ever, and strongly influenced by the technologies here developed.
Despite being such an influence, Bitshares still suffer from isolation.

**The isolation problem**

As I understand, the system expects balanced interaction between two main counterparts, with forced settlement as the focal point: supply and collateralization from DEX activity on one side, and additional demand from regular users/wider adoption. Without the latter, when the instant liquidation feature doesn't bring additional demand, forced settlement turns to be an anti-feature for the active counterpart.

**Why is it so hard to gain that adoption**

Why didn't Bitshares excel among literally thousands of bitcoin clones, at a time when smart contracts didn't go much further than colored coins, and there was no clue about substantial improvements in performance, scalability, governance, mining decentralization? When concepts like decentralized exchanges, DACs, DAOs, and stable coins didn't even exist?

There's been multiple factors, but one that stands out and remains: exclusion. Permanent influence from certain actors, through mass media and exchanges, to keep competition under control.

But Bitshares isn't the only blockchain harmed by obsolete rules and the space is maturing. We've seen Vitalik helping to make DPOS BFT more resilient, Daniel collaborating with the Bancor protocol, and so on.

Started researching about it just yesterday, some thoughts so far:

- I think we could fairly and safely remove forced settlement, if and while enhancing "instant liquidation" through the bancor network (instant conversion between multiple tokens instead force settling)

- [Resilience against market manipulation](https://blog.bancor.network/amid-pump-dump-boom-the-bancor-protocol-helps-tokens-fight-back-3730f85d034c)

- Strong incentives for bridges and gateways as they could set their own [relay tokens](https://support.bancor.network/hc/en-us/articles/360000471472-How-do-Relay-Tokens-work-), connectors and conversion fees:

- [Good for illiquid tokens](https://blog.bancor.network/solving-the-problem-of-cryptocurrency-illiquidity-and-token-conversions-bcf89ae67c98)

- It could bring tools to achieve certain degree of isolation between DEX activity and regular usage. Regular users could just ignore DEX complexity and even BTS at all if desired, while releasing pressure on the DEX for it to focus on strengthening supply, collateralization and orderbook trading incentives and mechanics.

- It's basically a liquidity network between decentralized exchanges. Besides the ability to feed prices from many more decentralized sources, I think the protocol itself has interesting features that could play well together with DEX parameters to enhance pegging.

No need to issue EOS compliant tokens to join (documentation seems outdated by the way).
The protocol looks relatively simple as Bitshares already has required core features, but still a hard work and a hardfork.

**The implementation would benefit all graphene blockchains, so joint development and funding are expectable.**

It sounds to good to be true (as to be ignored), let's try to refute these points and find out if it deserves the efforts.

**`Just throwing one raw idea, the main proposition is to do some research, put the findings all together and make it easier to identify milestones towards interoperability.`**

Start by reviewing the BancorX article, the linked Bancor support material, and the contracts_eos repository. Compare the proposed cross-chain liquidity approach with BitShares' existing forced settlement and instant liquidation features, then document whether the idea is viable and identify concrete interoperability milestones. Done means the research, objections, and next steps are assembled clearly enough to guide a future implementation proposal.
