Blockchain has many interesting aspects. Its relative newness makes it a concept many people have been curious about since 2014, when it started gaining global popularity.
One object of interest is how the blockchain works: how it seamlessly records millions of transactions and executes a large number of smart contracts, and the various sectors to which it could be applied.
Blockchain operations work effectively because their systems are interoperable. In this blog post, we’ll explore this feature of blockchain and see why it is so important to the entire technology ecosystem.
First of all, a revision of what blockchain is.
What is Blockchain?
A blockchain is a unique type of database that stores information in a secure, transparent, and difficult-to-alter way. It is also sometimes described as a digital ledger or record book distributed across many computers.
Each page of this ledger is called a "block," and these blocks are linked together in a chain—hence the name "blockchain." Every time a new block is added, it gets connected to the previous one, forming a continuous and unchangeable chain of data. This ensures that once information is recorded, it can't be changed without altering all subsequent blocks, which is very hard to do.
Blockchain technology is the foundation for various cryptocurrencies, like Bitcoin, but its use goes beyond digital money. It is also becoming popular in other sectors, such as government, healthcare, and real estate.
What is Interoperability in Blockchain Networks?
Interoperability in blockchain networks refers to the ability of different blockchain systems to work together and exchange information seamlessly. Let’s say you have several different blockchains, each with its own set of rules and functions. Interoperability allows these separate blockchains to communicate and share data without needing to go through any complex or inefficient process.
For example, if one blockchain records transactions related to supply chain management and another blockchain handles financial transactions, interoperability ensures that data can flow smoothly between these systems. This enables different blockchains to collaborate and create a more integrated and efficient ecosystem.
What are the Different Types of Blockchain Networks?
1. Public Blockchain:
Public blockchains are open to everyone. Anyone can join the network, participate in the process, and view the data. These blockchains are fully decentralised and maintained by a global network of nodes. Examples include Bitcoin and Ethereum. Because they are open, they rely heavily on consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) to ensure security and prevent fraud. Public blockchains promote transparency and inclusivity but can be slower and less scalable due to the large number of participants.
2. Private Blockchain:
Private blockchains are restricted to a specific group of participants. They are often used within organisations or between trusted partners. Unlike public blockchains, private blockchains are controlled by a central authority or a consortium of entities. Since they don't require global consensus, they offer greater privacy and faster transactions. However, they sacrifice some level of decentralisation and transparency. They are ideal for businesses needing secure and efficient operations.
3. Consortium Blockchain:
Consortium blockchains are a blend of public and private blockchains. They are governed by a group of organisations rather than a single entity. This type of blockchain provides a balance of security, privacy, and decentralisation. Members of a consortium blockchain can share control and decision-making, which enhances trust among participants. Examples include the Hyperledger Fabric and R3 Corda. Consortium blockchains are useful in industries like finance and supply chain management, where multiple parties need to collaborate.
4. Hybrid Blockchain:
Hybrid blockchains combine features of both public and private blockchains. They offer the flexibility to have both public and private aspects within the same network. This means that specific data can be made public while other parts are kept private, depending on the users' needs. Hybrid blockchains aim to offer the benefits of transparency from public blockchains and the security and efficiency of private ones. They are suitable for organisations that need to maintain privacy while also engaging with external parties.
5. Permissioned Blockchain:
Permissioned blockchains require users to be granted permission to join the network. They are controlled by a central authority or a group of organisations. This type of blockchain allows for more control over who can participate and what they can do. It provides higher security and efficiency but reduces the openness and decentralisation found in public blockchains. Permissioned blockchains are used in enterprise settings where access needs to be tightly regulated.
6. Permissionless Blockchain:
Permissionless blockchains do not require any permission to join or participate. They are completely open to anyone and operate on the principles of decentralisation and transparency. This type of blockchain is common in cryptocurrencies like Bitcoin, where anyone can contribute to the network and verify transactions. Permissionless blockchains are known for their openness and democratic nature but can face scalability issues due to the large number of participants.
What is Blockchain Operability?
Blockchain operability, or blockchain interoperability, is the ability of different blockchain networks to work together and share information seamlessly. Without operability, these blockchains operate in isolation and cannot communicate or exchange data directly.
Blockchain operability is crucial because it enables different blockchains to interact and function together, enhancing their overall utility. For instance, if you use Bitcoin on the Ethereum network, you could benefit from Ethereum's smart contracts while leveraging Bitcoin's value. This connectivity is achieved through protocols and standards that allow different blockchains to "speak" to each other.
By enabling such communication, blockchain operability makes the entire system more versatile and efficient. It supports various applications, such as cross-chain transactions and decentralised finance (DeFi) platforms, where assets from one blockchain can be used on another.
Why Does Interoperability Matter?
Here’s why interoperability matters:
1. Increased Efficiency:
Interoperability allows various blockchains to communicate and exchange information. This means transactions or data can be processed faster and more efficiently. For example, if a blockchain designed for financial transactions can interact with a blockchain used for supply chain management, businesses can simplify operations and reduce delays.
2. Enhanced Functionality:
Different blockchains have unique features and capabilities. Interoperability enables these distinct blockchains to complement each other’s strengths. For instance, one blockchain might specialise in security, while another focuses on scalability. By allowing these different blockchains to work together, you can leverage their best individual features, leading to more advanced and capable systems. This can lead to innovations and more robust applications that benefit from the strengths of multiple blockchains.
3. Broader Adoption:
When blockchains can interact with each other, it encourages more widespread adoption. Businesses and users are more likely to invest in and use blockchain technology if they know it can integrate with existing systems and technologies. Interoperability helps bridge the gap between various blockchain networks and other technologies, making it easier for more people to use and benefit from blockchain applications.
4. Improved Security:
Interoperability can enhance security by allowing blockchains to share and verify information across networks. For example, if a security breach occurs in one blockchain, other connected blockchains can help to detect and address the issue. This collective approach to security ensures that vulnerabilities are identified and managed more effectively, reducing the risk of widespread problems.
5. Cost Reduction:
Managing multiple isolated blockchains can be expensive and complex. Interoperability reduces these costs by allowing different blockchains to share resources and information. This shared infrastructure can lower operational expenses and simplify maintenance. Rather than building and managing separate systems for each blockchain, organisations can use interoperable solutions that streamline their operations and cut costs.
6. Seamless User Experience:
Interoperability in blockchain networks creates a smoother experience for users. It means that users can interact with different blockchains without needing to manage multiple accounts or platforms. For instance, if you can use a single wallet to manage assets across various blockchains, it simplifies the process and makes it more user-friendly. A seamless user experience encourages more people to use blockchain technology and enhances overall satisfaction.
Challenges in Achieving Interoperability
Achieving interoperability in blockchain networks involves overcoming several significant challenges. Here are the main issues:
1. Different Protocols and Standards:
Each blockchain network operates using its own set of rules and protocols, often tailored to its specific use case. These differences create obstacles in ensuring smooth communication and data sharing between different blockchains. Therefore, creating a common standard or protocol to facilitate seamless interaction among various blockchains could be a challenge.
2. Scalability Issues:
Many blockchains have limitations on transaction speed and processing power. For instance, Bitcoin can process about 7 transactions per second, while Ethereum handles around 30 transactions per second. When connecting multiple blockchains, the combined load can strain the network's capacity, leading to delays and inefficiencies.
3. Security Concerns:
When different blockchains interact, vulnerabilities in one blockchain can potentially expose others to threats. For example, if a smart contract on Ethereum is compromised, it could affect transactions between Ethereum and other blockchains. Ensuring strong security measures that protect all interconnected blockchains from breaches is a complex challenge that needs addressing to maintain trust and reliability in the network.
4. Data Format Compatibility:
Different blockchains often use various data formats and structures, which can complicate the process of data exchange. One blockchain might store data in a specific way that is not directly compatible with another blockchain's format. This incompatibility requires solutions that can translate or convert data between different blockchains without losing information or introducing errors.
5. Regulatory and Governance Issues:
Different regions and organisations may have varying regulations and compliance requirements. Data privacy laws like GDPR in Europe could affect how data is shared between blockchains. Navigating these regulatory landscapes while ensuring that all blockchains adhere to necessary rules and standards is a complex and continuous challenge.
Current Solutions and Technologies
Several current solutions and technologies address some of the challenges mentioned above, aiming to make various blockchains compatible. They are as follows:
1. Cross-Chain Platforms:
Cross-chain platforms are designed to connect different blockchains. They enable transactions and data transfers between separate blockchains seamlessly. Polkadot and Cosmos are prominent examples of cross-chain solutions. Polkadot uses a relay chain and parachains to allow different blockchains to share information and functionality. Cosmos employs a hub-and-spoke model, where its hub (the Cosmos Hub) connects to various other blockchains (zones), facilitating their interoperability. These platforms are vital to enabling blockchain operability because they create a framework where different blockchains can interact without needing to be redesigned.
2. Atomic Swaps:
Atomic swaps are another technology that aids interoperability. They allow users to exchange cryptocurrencies from different blockchains directly, without relying on a third party. This process uses smart contracts to ensure that the exchange is completed securely and automatically. For example, an atomic swap might enable a user to exchange Bitcoin for Ethereum directly from their wallet.
3. Interoperability Protocols:
Interoperability protocols are standards and technologies that define how different blockchains should interact. Examples include the Interledger Protocol (ILP) and the Hyperledger project. ILP allows different blockchains and ledgers to communicate and transfer value across various systems. Hyperledger, a collaborative project hosted by the Linux Foundation, focuses on developing open-source frameworks that support interoperability between different blockchains.
4. Sidechains and Pegged Sidechains:
Sidechains are separate blockchains that are attached to a main blockchain (mainchain) through a two-way peg. This allows assets to be transferred between the mainchain and the sidechain. For example, the Bitcoin sidechain, Liquid, is linked to the Bitcoin mainchain, enabling faster transactions and additional features. Pegged sidechains function similarly but are often used to connect different blockchains with varying technical standards. These technologies enhance blockchain operability by creating additional pathways for asset movement and interaction across blockchains.
5. Wrapped Tokens:
Wrapped tokens are assets from one blockchain that are represented on another blockchain. For instance, Wrapped Bitcoin (WBTC) is a token on the Ethereum blockchain that represents Bitcoin. This allows Bitcoin holders to use their assets within the Ethereum ecosystem, benefiting from Ethereum's smart contract capabilities. Wrapped tokens are a practical solution for enhancing interoperability in blockchain networks by enabling assets to be used across different blockchains.
