Good evening dear readers and crypto friends, back again with Stevano, on this occasion I will discuss the Atom project
Atom Swap
Cross-chain is a cryptocurrency exchange between users. Basically, A sends Coin A to the B Coin B party address through the blockchain, while B does the same thing with Coin B. This action occurs independently on the parallel blockchain, in a one-way way. Such arrangements increase the possibility that one party will never respect the end of the agreement. One way to overcome this problem is the involvement of trusted third parties. On the other hand, atomic cross-chain exchanges solve this problem without the need for third parties.
Atomic swap requires each party to make a transaction contract. The contract contains output that can be spent by the opponent, but the rules needed to collect are different for each party involved.
