Atomic swaps require the supporting chains to have minimal scripting capabilities, and as far as I know all the bitcoin derivatives allow this. It is necessary to create a redeem script that has two branches, an immediate one and a time locked one. The immediate branch uses a oneway function supported on both chains and the time locked branch for the refund transaction with a regular signature. There is a four phase process in the exchange and this requires careful analysis of the timing. (This might work poorly with chains with unreliable performance at times of overload.) See the following example of how this might all be done. https://github.com/decred/atomicswap

Once atomic swaps are sorted it will be easy to add xmr to the various dex projects such as dcrdex https://github.com/decred/atomicswap

Tendermint Core / CometBFT — a state machine replication engine (written in Go);

There are good use-cases, but to much focus on cryptocurrencies. Frameworks are not well designed to be used in other use-cases. Best that I have found that doesn't forces you to a specific architecture is Tendermint, but is not even close to state-of-the-art performance and scalability. Everything else is designed around cryptocurrency and smart contracts.

BFT is an algorithm that ensures that the whole network works well even if a few members are acting fraudulently. As long as these fraudulent members are less than 33% of those who have voting power, the network will work fine. Those with voting power are those with something at stake. Cosmos uses a type of BFT consensus engine known as Tendermint. Cosmos uses Tendermint because it provides the best support for building POS blockchains.

BlockX is based on Tendermint Core, which relies on a set of validators that are responsible for committing new blocks in the blockchain. These validators participate in the consensus protocol by broadcasting votes which contain cryptographic signatures signed by each validator's private key.

Built with Cosmos and Tendermint.

Haqq is a scalable, high-throughput Proof-of-Stake blockchain that is fully compatible and interoperable with Ethereum. It's built using the Cosmos SDK which runs on top of Tendermint Core consensus engine.Haqq allows for running vanilla Ethereum as a Cosmos application-specific blockchain. This allows developers to have all the desired features of Ethereum, while at the same time, benefit from Tendermint’s PoS implementation. Also, because it is built on top of the Cosmos SDK, it will be able to exchange value with the rest of the Cosmos Ecosystem through the Inter Blockchain Communication Protocol (IBC)Features
