If I got it right, you are talking about true decentralized cypherpunk options, which is a great as an idea, but I can only imagine all the hassle associated with this. I have to dig deeper into the Grin’s principles and the math behind it, but for now it seems that even a simple implementation of oracle will be a big obstacle.

Another post of yours caught my attention [[NEW] Grin peg chain for Cosmos Hub need : [OLD] Can I do atomic swaps between Cosmos (ATOM) and Grin? - #15 by SiriusB](https://forum.grin.mw/t/new-grin-peg-chain-for-cosmos-hub-need-old-can-i-do-atomic-swaps-between-cosmos-atom-and-grin/5042/15)  
and I think that this is what we really need here.

What might a small business need to accept Grin in a fully non-KYC manner? At the very least a good Grin/BTC spot dex OR/AND liquid derivatives to hedge the exposure. So here we are with 3 possible solutions: (correct me if I’m wrong or forgot something)

1. Atomic SWAPs
2. Rust node running on the Cosmos VM
3. GRIN&BTC Pegs on Tendermint exchange (similar to Binance DEX)

**Atomic SWAPs**

Sounds like a decent solution, but what I found up to date is a version with 12h lockup which is not acceptable. Can LN solve this?

**Full rust node running on a VM (Cosmos)**

Is it even possible to implement a decentralized Rust node acting as a collateral agent on the Cosmos network? Unfortunately, my current knowledge does not allow to answer this question.

**Tendermint exchange**

This seems to be the only practical solution available right now. If you could create a grin peg, I see two possible scenarios:

A. Run an exchange on the existing Cosmos network, with their fees and slow (for modern trading) block time: 7-8 seconds.

B. Fork Tendermint and create a new chain with 1-second block time specifically for Grin-related products. Pegs could be exchanged for real Grins and BTC through atomic swaps (as Binance DEX docs state). In this case, a 12-hour lockup will no longer be a big problem.

This particular solution looks very promising to me, but some important questions arise, such as: _“Will there be enough incentives to run a validation node, assuming that they are paid with trading fees?”_

Those are my thoughts. I’m not a blockchain expert but have a decent programming experience. Would like to contribute to this crazy industry. 🙂
