Changing things in cryptocurrency and with a multitude of questions getting asked, one stands out: so, what is an atomic swap crypto? In a nutshell, it is a method to exchange cryptocurrencies between different blockchains, in an entirely decentralized manner, unlike centralized exchanges. Atomic swaps make P2P trading quite innovative by going directly, and securely. This comprehensive guide explains how atomic swap works; it will paint the history, technicalities, advantages, disadvantages, and the future of atomic swaps.

Direct Crypto Trading Without Third Parties: How It Works

Atomic swap is a decentralized, trust less exchange mechanism for another cryptocurrency across heterogeneous blockchain platforms without dependence on intermediaries. Atomic stands for all or nothing: the process either executes fully or is completely cancelled, ensuring that there are no fund proceeds whatsoever. 

The two sides work against one another with Hash Timelock Contracts (HTLCs) that provide conditional execution or refund safety: both the parties either receive their coin or their original money back. In this way, the risk of the counterparty is removed, as is the need for any exchange or custodian.

The Hassles of Using Traditional Crypto Exchanges

If you have ever been trying to change one exchange for another, you know very well how difficult this process is. I will explain my recent experience:

I wanted to carry out a transaction on Coinbase, and they wanted everything: my Social Security number, my phone number, address, pictures- they wanted to know more about me than my accountant!

And then, there was a $1 transaction fee on my Bitcoins. The worse one? Bitcoins were no longer in my bank account. They were now in my Coinbase wallet. I somehow had trusted that they wouldn’t steal make away from me- or lose my crypto.

Next was the selling of Bitcoins (more cost) for cash, which was then used to buy Litecoin (yep, more costs). Afterward, I deposited the coins to my personal account (yet another network charge)

The entire procedure was lengthy, it cost a fortune in fees, and it also demanded me to trust an entity I barely knew. There has got to be an easier way.

The Rise of Atomic Swaps: Revolutionizing Peer-to-Peer Crypto Trading

Imagine eliminating all the unnecessary steps. That is what an atomic swap cryptocurrency can perform. It is almost like meeting somebody in the digital world and trading coins between your own hands. 

This is how it worked after my trial: 

  • I locked my Bitcoin in a special piece of code. 
  • Another person also locked his Litecoin in the same password. We had already set the terms of the trade, so there was no bargaining. 
  • Once I was given the code to unlock the other person’s Bitcoin, I gave my counterpart the key to unlock Litecoin. It was like we both launching our trading cards at the same time. 
  • The word “atomic” means the swap can be performed exactly as desired or not performed at all. This eliminated any fear that I might lose my Bitcoins to somebody who refused to disclose their Litecoin.

Behind the Scenes

To a technical geek, the crypto atomic swap technology utilizes a “hashed time lock smart contract” such as one would say in layman terms. However, do not be scared off by this name; at its most elementary, it can be likened to an electronic safe with two major features:

Nothing will get out until both parties put their coins into it.

If anyone fails to return and the coins are duly credited to both parties on either end, then after a certain stipulated period the coins should be automatically unlocked and sent back to their original owners.

I just love not being able to do anything wrong. There is no way to lose funds to a hacker who, due to a security flaw in the exchange, might just delay refunding me my money. There are no hidden fees. There is no waiting for transaction clearances.

Another thing I would appreciate is that there was no need to submit a driver’s license or any other personal information to exchange just a few coins.

The Challenges of Atomic Swaps: Not Perfect Yet

In my research, I have discovered the constraints of atomic swaps. Both currencies need to support the same hashing algorithm and the same smart contracts. That would rule out swapping just about any cryptocurrency using this method-at least for now.

However, technology is changing very fast. What atomic swap crypto can do today is merely the first step towards what it will accomplish in a short while.

What Makes Atomic Swaps So Exciting for the Crypto Community

After exploring both notions and experiments on my end, I came to embrace cryptocurrency atomic swap technology. The reasons:

  • I just could not put any more charges on an exchange.
  • I’ve been worried about some hacking attempts on the exchange.
  • All day I do not want to wait for my transactions to clear.
  • My account of being robbed for exchanging some coins should never happen again.

Atomic swap crypto is basically all that I wished for. We are one step closer to some truly decentralized commerce that the crypto industry was created to offer.

Consider it from this angle: The cryptocurrency industry was set up to get rid of the middlemen from financial transactions. Somehow central exchanges found their way: central exchanges are now working just like banks from the digital world. Crypto atomic-swap technology takes us back to where crypto started, that is, person-to-person trades with no third party involved to decide or have control over our funds.

Your next thought about exchanging some of your cryptos should go to the thought of an atomic swap crypto. Your wallet (and your security) will honour you.

Just like trading Yu-Gi-Oh cards on the playground, the blockchain and cryptocurrency world should be straightforward, simple and trustworthy. The technology has turned this dream of atomic swaps for cryptocurrency into a reality.
