Introduction
Blockchain technology has fundamentally transformed industries grappling with the limitations of centralized operations. By establishing a zero-trust ecosystem, it has introduced processes that are exceptionally neutral, immutable, and fully transparent compared to traditional computing environments.
Now, as blockchain’s credibility is well-established across various sectors, the technology encounters the oracle problem – dependence on an Internet connection. Blockchains lack inherent communication capabilities with external APIs or other blockchains, limiting their interaction with traditional systems and hindering interoperability with other blockchains.
As the concept of a multi-blockchain world gains momentum, interoperability protocols are becoming essential for the seamless exchange of tokens and data between different blockchains.
In this article, we will delve into the importance and workings of blockchain interoperability for businesses, providing insights into the process and the changes its implementation might bring.
The Origin of Blockchain Interoperability Solutions
Blockchain interoperability is crucial in a manner akin to globalization. It empowers blockchain systems to unlock asset flow that is typically confined within individual chains.
Similar to nations, blockchains specialize and excel in distinct domains. Some excel in minting NFTs, while others offer minimal transaction fees. The choice of blockchain can significantly impact the scalability and security of decentralized applications (dApps).
Connecting these specialized blockchains goes beyond enhancing existing applications; it fosters the emergence of new apps and use cases, echoing historical economic shifts from globalization’s business expansions to the advent of e-commerce.
However, at a practical level, the absence of interoperability has posed persistent challenges, prompting businesses to seek solutions focused on blockchain interoperability.
For instance, the lack of direct interoperability between Ethereum and Bitcoin restricts Bitcoin users from utilizing their funds on Ethereum without centralized exchanges. Similarly, although Ethereum and Binance Smart Chain both support USDT, transferring USDT between them or other blockchains isn’t straightforward.
Blockchain advocates aim to integrate blockchain into traditional finance, but the mismatch between different blockchain infrastructures complicates transactions between banks, potentially leading to a fragmented rather than unified financial system.
Exploring blockchain interoperability underscores its critical importance for decentralized platform owners seeking scalability and associated benefits. Let’s delve into the significant advantages of achieving blockchain interoperability.

Common Blockchain Interoperability Solutions
As blockchain technology evolves, ensuring different blockchain networks can communicate and operate seamlessly together has become paramount. Blockchain interoperability solutions address this need by enabling diverse blockchain systems to interact, share data, and execute transactions efficiently across multiple platforms. Here are some common blockchain interoperability solutions:
Token Swaps
Token swaps involve trading a token on a source chain and receiving a separate token on the destination chain. This is usually done through atomic swap protocols and cross-chain automated market makers (AMMs) that place different liquidity pools on each blockchain.
Token Bridges
Token bridges lock or burn tokens through a smart contract on the source chain and then mint or unlock tokens on the destination chain. This process allows assets to move across blockchain networks, increasing token utility.
Native Payments
Native payments involve an application on the source chain triggering a payment on the destination chain in the native asset. Cross-chain payments can also be made on the source chain based on data from a different blockchain network.
Contract Calls
Contract calls involve a smart contract on a source chain calling a function on a destination chain’s smart contract, potentially based on data from the source chain. This process can create complex cross-chain applications involving token bridging and swaps.
Blockchain Interoperability Solutions
Web2 Validation
Web2 validation uses a centralized service to execute cross-chain transactions. For example, users can leverage centralized exchanges to swap or bridge their tokens by depositing assets in a source chain address controlled by the exchange and withdrawing tokens to a destination chain address.
External Validation
External validation involves validator nodes from all blockchains in a cross-chain interaction validating the source blockchain’s state and triggering a subsequent transaction on the destination chain. This process uses decentralized oracle networks, multi-party computation, and threshold multi-signature contracts.
Local Validation
Local validation occurs when cross-chain interaction counterparties verify each other’s state. If both consider the other valid, a cross-chain transaction is executed, resulting in successful peer-to-peer cross-chain transactions, often called atomic swaps.
Native Validation
Native validation happens when a destination blockchain in a cross-chain interaction verifies the source blockchain’s state to confirm transactions and then executes a subsequent transaction on its own chain. This is typically performed by running a light client of the source chain in the destination chain’s virtual machine or running both side-by-side.
