Blockchain Interoperability
“The ability of different blockchain systems to communicate and interact with each other. This allows one blockchain to influence or update the information on another blockchain through cross-chain transactions. Essentially, it means that various blockchain networks can work together seamlessly.”
Introduction
Traditional banking faces a significant challenge in cross-border payments. Many businesses deal with international customers. They have to send money to them and the slow and expensive process is a major problem. Crypto helped a lot by offering a faster way to send and receive money but it found its issues later. The current crypto domain is fragmented and has cross-chain border issues. It means there are many different currencies and blockchain does not easily work together. As a result, users find it difficult to use crypto regularly. The solution is making blockchains interoperable to make different blockchain networks communicate with each other. With a unified system, people can send payments to anyone, anywhere, at any time. The technology that can make it possible is “Cross-chain protocols”.
In this blog, we will learn what are cross-chain protocols, and how they work, the benefits of cross-chain protocols, why we need interoperable blockchains and how they can help us unlock the full potential of web3.
What is Cross-chain Protocol?
A cross-chain protocol is a bridge that has smart contracts, protocols or other mechanisms. These functions allow for two or more distinct blockchain networks to communicate, making a unified system. Consider real-world bridges: like that this bridge enables the transfer of assets or data between chains which ultimately overcomes the barriers of siloed blockchains. However. without these interoperability solutions, there will be a metropolitan city that has a lot of places to go but no bridge to commute. That is why multiple blockchain networks can help users execute fund transfers, lending, swapping, staking and deposits. As a result, different blockchain networks can communicate seamlessly across various isolated blockchains. Some examples include Polkadot, Cosmos and Thorchain.
How Cross-chain Protocol Works?
Cross-chain protocols function by unifying communication and transactions between different blockchain networks. Some components help it work:
- Interoperability: Cross-chain protocols help different blockchains to understand and exchange data with each other. Every blockchain and token has its own set of rules and data structures but the protocol bridges these differences.
- Cross-Chain Transactions: Cross-chain protocols help transactions happen across blockchains. It allows assets or information to move from one network to another without the need for a central authority or intermediary.
- Atomic Swaps: Some cross-chain protocols use atomic swaps. In this, transactions are only completed if both parties fulfil the conditions. As a result, there is trust and security across different blockchains.
- Smart Contracts: When smart contracts exist on one blockchain, they trigger actions on another blockchain too. As a result, it enables seamless interaction between networks.
Why We Need Cross-Chain Protocols?
Blockchain technology is not without challenges. The major challenge that users face in the crypto field is its fragmented nature. Moreover, this fragmentation limits the broader adoption of blockchain. As a result, it is difficult for different blockchains to interact and collaborate. Cross-chain protocols are the solution that allows for smooth communication between various blockchains by creating a more integrated ecosystem. The question of why we need cross-chain protocols has different factors including:
- For DeFi Opportunities: Cross-chain interoperability protocols are important for DeFi platforms to interact across different blockchains. It helps users to access lending, borrowing, and trading services on a broader level. As a result, there is reduced liquidity isolation. It also encourages a more interconnected and efficient DeFi ecosystem and provides users with flexibility options.
- For Simplified User Experience: Cross-chain protocols cut processes like bridging and swapping tokens across networks. However, there is a simplified user experience which helps users interact with assets and applications from multiple blockchains using a single wallet. The outcome is a simpler and more user-friendly experience.
- For Multi-Chain dApp Development: Using cross-chain protocols, developers can create applications using the strengths of multiple blockchains. They do not need to be limited to the capabilities of one network. But, cross-chain protocols help them with multi-chain dApp to bring the best features of different blockchains. It leads to more powerful and versatile decentralized applications.
Benefits of Cross-Chain Protocols
Using cross-chain protocols can enable seamless communication between different networks. It improves liquidity, boosts scalability, and encourages the growth of decentralized applications across multiple blockchain ecosystems:
Enhanced Interoperability:
Cross-chain protocols help different blockchains work together. It creates a seamless ecosystem where assets and data can flow freely across multiple chains. As a result, it reduces the silos created by individual blockchains and fosters collaboration across different blockchain platforms.
Increased Liquidity:
These protocols allow assets to move between blockchains. It enables greater liquidity. For instance, when users transfer tokens from one blockchain to another, the cross-chain protocol allows them to access more trading pairs and liquidity pools. The outcome is a more efficient market.
Improved DeFi Functionality:
Cross-chain protocols allow decentralized finance (DeFi) applications to interact with multiple blockchains. As a result, there is an interconnected DeFi ecosystem where users can access services like lending, borrowing, staking, and yield farming across different blockchains, without the need for complex bridging or token swapping.
Asset Diversification:
Users can hold and use assets across different blockchains. It increases their ability to diversify portfolios. For example, users can leverage assets on Ethereum while also participating in the ecosystem of another blockchain like Binance Smart Chain or Solana.
Cost and Time Efficiency:
When there is a need to transfer assets between chains, cross-chain protocols help in cutting the need for mediator systems or services. It reduces the time, cost and complexity of cross-chain transactions. Also, it makes the process fast and efficient.
Reduced Centralization Risk:
Using cross-chain protocols also benefits decentralized apps and assets. They no longer remain restricted to a single blockchain. This enables decentralization which increases security and reduces the risk of a single point of failure that could affect the whole ecosystem.
Better Scalability:
Cross-chain protocols enable multiple chains to work together which helps scale decentralized applications (dApps) more effectively. Nevertheless, developers can also utilize the strengths of different blockchains (e.g., speed, security, cost-effectiveness) to build more robust and scalable applications.
Support for Multi-Chain dApps:
Cross-chain protocols make possible the development of multi-chain decentralized applications (dApps). These apps are decentralized and they leverage the unique features of various blockchains. However, developers can choose the best blockchain for each part of their app, leading to more powerful and flexible dApps.
Faster Transaction Speed:
When there are cross-chain protocols in systems, users can experience faster transactions. They can optimize how assets and data are exchanged across blockchains. For example, a user can transfer tokens from one blockchain to another in seconds without waiting for traditional bridges or intermediaries.
Increased Adoption of Blockchain:
Cross-chain framework can solve the fragmentation and create a more interconnected ecosystem. However, it also increases the adoption of blockchain technology. It causes few barriers to entry, users, businesses and developers can easily integrate and utilize different blockchain networks.
Examples of Cross-Chain Protocols:
Cross-chain protocols enhance interoperability within the blockchain space. These are just a few examples of real-life cross-chain protocols that connect isolated blockchains and help promote seamless data transfer, asset exchange, and smart contract execution across different platforms:
Polkadot:
Polkadot enables different blockchain networks to incorporate through a shared security model. This cross-chain protocol connects blockchains via para chains. These chains allow them to exchange data and assets while maintaining their individual features and consensus mechanisms. Polkadot cross-chain protocol aims to create a decentralized web where different chains can share information. As a result, it improves scalability and enables a variety of use cases.
Chainlink:
Chainlink introduces its Cross-Chain Interoperability Protocol short as CCIP. This protocol is designed to connect smart contracts across various blockchains. However, CCIP leverages Chainlink’s Oracle network that allows for decentralized applications (dApps) to access data and execute functions across multiple blockchains. Lastly, it helps in transferring tokens, managing cross-chain liquidity, and executing smart contracts that span multiple blockchains. As a result, it promotes better interoperability in the decentralized ecosystem.
Thorchain:
Thorchain uses a decentralized liquidity network. This network allows for the cross-chain exchange of assets without the need for wrapped tokens or centralized intermediaries. Moreover, it enables users to swap assets between chains like Bitcoin, Ethereum, and others. This cross-chain protocol works by using liquidity pools for cross-chain swaps, providing a decentralized and secure way to move assets between blockchains.
Avalanche:
Avalanche blockchain offers cross-chain transactions through its C-Chain (Contract Chain) and custom subnets. Avalanche’s cross-chain capabilities are foral for developers. It helps them create subnets and connect them seamlessly with the Avalanche ecosystem. As an outcome, it facilitates interoperable applications while maintaining flexibility for developers to build blockchain-specific solutions.
