What is Cross-Chain Communication?

The widespread usage of blockchain platforms has brought to light difficulties with processing performance and scalability in the earlier blockchains. Because all blockchains run separately and do not connect with one another, developers have a unique difficulty. This is because consumers are unable to see the full potential of blockchain technology and its advantages.

Because blockchain projects have widely varied architectures, in the end, it may be hard to transmit data between chains without the need for extra software or third-party involvement. 

This is why cross-chain communication solutions are becoming more popular. There are now numerous cross-chain communication protocols in place for blockchains to share information.

Interoperability is a big concern for blockchain developers because it is one of the elements that is mostly lacking in existing blockchain structures. While blockchain bridges are one method of ensuring interoperability, cross-chain communication technologies can aid in the development of more efficient environments.

However, at the moment, blockchains are unable to operate to their full potential due to a lack of cross-chain communication between different systems. 

As the processes evolve, more applications and solutions become available to blockchain developers. Cryptocurrency users will get advantages from faster transaction computational power and quick trades between different assets. Cross-chain communication still has a long way to go, but there has been a significant advancement in this area of blockchain technology.

One of the most popular cross-chain communication devices at the moment is Atomic swaps. Atomic swaps enable the possibility for peers to transfer tokens from one wallet to another by using a smart contract. This prevents the need to buy cryptocurrency from an exchange.

This technique disables the need for a third-party exchange and lets peers directly swap cryptocurrency.

Another blockchain cross-chain communication example is the Stateless Simplified Payment Verification (SVP). This technology enables blockchains to evaluate the authenticity of transactions without preserving complete transaction details. Therefore, this approach allows blockchains to interact without needing to exchange large volumes of data.

Merged consensus connections, relays, and chain federations are some more cross-chain communication tools. All of these communication techniques entail varying degrees of monetary investment. 

The ideal solution for cross-chain communication is generally defined by the fundamental properties of the two blockchains included. The lightning network, for example, is based only on the notion of atomic exchanges. 

Nevertheless, due to the highly variable structure of blockchain-based systems, Atomic swaps are not always the ideal option for ensuring cross-chain communication.
