I would say that Atomic Loans is quite a bit different from that paper. The assets described in the paper (JPY-Token) and (L-BTC) would exist on a Bitcoin sidechain. Atomic Loans work directly on the Bitcoin mainnet. Additionally, this paper is describing the Atomic Swapping of these assets (JPY-Token) and (L-BTC). Atomic Loans talks about the creation of debt agreements using the underlying technology of Atomic Swaps. Interesting to read though. My main concern would be Blockstream controlling the sidechain.

A lot of the issues discussed in topic are simply not relevant. Needing a full node on each blockchain to do a swap is just not necessary.

There is already a team working on cross-chain atomic swaps and has a working MVP on testnet.

You can swap using Ledger and MetaMask

I think it's important to distinguish the difference here between "Atomic Swaps Wallet with Decentralized Exchange, Changenow and Evercode" and the true technology behind this https://blockgeeks.com/guides/atomic-swaps/

Saying to avoid anything associated with Atomic Swaps is completely unwarranted when there are great projects out there building real solutions that help users exchange cryptocurrencies cross-chain without middlemen.

A great example of this is Liquality: https://liquality.io

(current swap interface works with Testnet Bitcoin and Rinkeby Ether (https://liquality.io/swap/)

And it's completely open source: https://github.com/liquality/liquality-swap

Hey all, interesting views on Atomic Swaps. I personally think Atomic Swaps are the future, and really the only way people should be exchanging cryptocurrencies, because the risk of losing your funds is too high. Right now there are few projects working on Atomic swaps, which means liquidity will be low. But this won't be the case forever.

Also on the note of smaller coins may need exchanges, I'd disagree. Last I heard, Binance charges 1 million dollars to be listed on their exchange. In the current market, that's definitely a large barrier to entry for new coins and projects trying to be listed. With Atomic Swaps, that cost is 0.

Also the fact that KYC is not required is a huge bonus. It may work to help onboard more crypto users, more quickly, rather than having to wait a month to get approved by an exchange.

There's actually a project actively working on atomic swaps called Liquality (https://liquality.io) you can actually swap testnet coins right now https://liquality.io/swap/ (Testnet Bitcoin and Rinkeby Ether).

Let me know if anyone wants to trade 

Would love to hear any feedback on this paper from the community.

Use cases:

Enable individuals to put in Bitcoin as collateral and receive a stablecoin loan on Ethereum without any middlemen.
Decentralized and disintermediated margin trading for Bitcoin
Short Ethereum assets by creating a loan using Bitcoin as collateral, and an Ethereum asset such as ether or ico token

Recently published paper on the idea of Atomic Loans. Essentially using the core concepts of Atomic Swaps (locking funds in an HTLC, and revealing secrets at certain points in time to unlock the funds) to enable the creation of cross-chain debt agreements, which functions by locking funds at different intervals in time, and revealing secrets that correspond to the stage in which the loan is in.

Recently added a PR to Bitcoin BIPs Repo. This is an optimized HTLC using the same inputs, but saves 1 byte of data for each P2SH.

Looking for community feedback on this.
