Every 12 months, we see new blockchain networks being developed to sort out particular niches inside sure industries, every blockchain having specialised features primarily based on its function. For instance, layer-2 scaling options like Polygon are constructed to have ultra-low transaction charges and quick settlement instances.
The enhance in the variety of new blockchain networks is additionally a results of the recognition that there is nobody good resolution that might be ready to meet all of the wants related to blockchain expertise suddenly. Therefore, as extra organizations grow to be conscious of this rising expertise and its capabilities, the interconnection of those distinctive blockchains is turning into vital.
What is interoperability?
Blockchain interoperability refers to all kinds of strategies that allow many blockchains to talk, share digital property and knowledge and work collectively extra successfully. This makes it attainable for one blockchain community to share its financial exercise with one other. For instance, interoperability permits transmitting knowledge and property throughout completely different blockchain networks through decentralized cross-chain bridges.
Interoperability is not one thing that the majority blockchains have as a result of every blockchain is constructed with completely different requirements and code bases. Since most blockchains are naturally incompatible, all transactions have to be performed inside a single blockchain, regardless of what number of options the blockchain may need.
Marcel Harmann, founder and CEO of THORWallet DEX — a noncustodial decentralized finance (DeFi) pockets — advised Cointelegraph: “Interoperability can be understood as freedom in data exchange. Currently, base layer protocols cannot communicate with each other effectively. Layer-1 protocols like Ethereum or Cosmos have smart contracts built into their fabric, only permitting secure data exchange within their own ecosystems. Digital asset transfers that leave the network pose a question: How can a blockchain trust the state validity of another blockchain?”
Harmann continued, “Consensus mechanisms on each blockchain decide the canonical history of all the transactions that were validated. This produces extremely large files that must be processed with each block and can only be viewed in the specific language native to the blockchain. Interoperability between two or more blockchains refers to one or both chains being able to understand and process the history of the other chain, thus enabling, for example, the exchange of assets between different layer-1 networks.”
Even although it appears apparent that public blockchain tasks must be designed with interoperability in thoughts from the begin, this is not all the time the case. However, organizations are more and more calling for interoperability due to the advantages of sharing info and dealing collectively.
Why is interoperability necessary?
To understand the full potential of decentralization, it is helpful for
folks collaborating in a number of blockchains to be linked by way of a single protocol. This reduces friction for the person since they’ll entry completely different decentralized purposes (DApps) with out having to change networks.

Due to blockchains working independently from one another, it’s troublesome for customers to make the most of the advantages introduced by every community. To achieve this, they want to maintain tokens supported by every blockchain to interact with the protocols inside their community.
Interoperability can repair this downside by enabling customers to use one token throughout a number of blockchains. In addition, by enabling blockchains to talk with one another, a person can entry protocols on a number of blockchains with higher ease. Because of this, there is a greater probability that the business’s worth will proceed to develop.
Fabrice Cheng, co-founder and CEO at Quadrata — a Web3 passport community — advised Cointelegraph:
“Interoperability is crucial because it’s one of the key benefits to blockchain technology. Decentralized open-source technology allows the creation of products that are interoperable across chains, enabling more users, businesses and institutions to stay interconnected.”
Cheng continued, “People who use blockchain technology want to make sure people are screened, KYC-verified and have good credit behavior. DeFi users can access trading options or have access to real-time price feeds. Interoperability is an efficient way to remove intermediaries for users and allows businesses to focus on their core values.”
When it comes to decentralized finance, giving merchants extra methods to use their property can deliver extra development and alternatives to the sector. For occasion, multichain yield farming permits traders to generate a number of returns as passive earnings on many blockchains for proudly owning a single asset.
The investor would solely want to maintain Bitcoin (BTC) or a stablecoin like USD Coin (USDC) after which unfold it throughout a number of protocols on completely different blockchains through bridges. Interoperability may also enhance liquidity throughout a number of blockchain networks since will probably be simpler for customers to transfer their funds throughout completely different chains.
Interoperability doesn’t solely refer to connectivity between blockchains. Protocols and good contracts are additionally interoperable. For instance, t3rn, a wise contract internet hosting platform, permits good contracts to function on a number of blockchains. This works by the good contract being hosted on the good contract platform and being deployed and executed throughout completely different blockchain networks. Interoperable good contracts make it simpler for builders to create cross-chain purposes and for customers to run cross-chain transfers.
Interoperable good contracts will make it simpler for customers to entry a number of decentralized purposes since they gained’t have to change networks. For instance, suppose a person makes use of a DApp on Ethereum and desires to entry a lending protocol on Polkadot. If the Polkdadot-based DApp has an interoperable good contract, they entry it on Ethereum.
Oracles are one other protocol that may profit from interoperability. Oracles are entities that join real-world knowledge to the blockchain through good contracts. Decentralized oracle platforms like QED can join oracles to a number of blockchain networks, making it attainable for real-world knowledge to be shared throughout blockchains. In addition, oracles can take knowledge from an API or sensor and submit it to a wise contract to activate as soon as sure circumstances have been met.
For instance, a provide chain has a number of organizations that use completely different blockchain networks. Once a element in the provide chain reaches its vacation spot, the oracle can submit knowledge to the good contract confirming its supply. Once supply is confirmed through an oracle, the good contract releases a cost. Since the oracle is linked to a number of blockchains, every provider can use the community of their alternative.
Interoperability is additionally necessary for the alternate of digital property between blockchain networks. One of the most typical methods this is performed is by the use of cross-chain bridges. In easy phrases, cross-chain bridges enable customers to switch tokens from one blockchain to one other.
Wrapped tokens, for instance, enable customers to use Bitcoin (BTC) on the Ethereum community as Wrapped Bitcoin (wBTC). This is necessary in the DeFi business since customers can interact with DeFi with out shopping for a platform’s native token, which can be extra risky than stablecoins or blue chip cash like BTC or Ether (ETH).
Being ready to simply transfer property between blockchain networks is a serious advantage of interoperability. Anthony Georgiades, co-founder of the Pastel Network — a nonfungible token (NFT) and Web3 infrastructure and safety mission — advised Cointelegraph:
“Interoperability is of vital importance to the blockchain industry due to the diversity of data and assets found within the crypto ecosystem. Decentralized cross-chain bridges are necessary to facilitate transfers between different kinds of tokens or assets.”
The key to the success of blockchain expertise might be the degree of interplay and integration between the many blockchain networks. Because of this, interoperability between blockchains is essential because it reduces the barrier to entry for customers who need to interact with protocols throughout a number of networks.

Interoperability throughout blockchains will improve productiveness all through the complete crypto sector. Users can shortly transfer knowledge and property throughout blockchains, rising flexibility for everybody concerned. Instead of being tied to a single blockchain, good contracts can perform on a number of networks and oracles will submit real-world knowledge throughout completely different platforms. When mixed with the benefits of public decentralized blockchains, interoperability ought to present the foundation for widespread blockchain adoption and utilization.
Georgiades continued, “Therefore, interoperability allows users to transmit cryptocurrency from one blockchain to another and enables users to post tokens or NFTs as collateral for other assets. An interoperable Web3 world is a vision we are tirelessly working towards. A multichain ecosystem facilitated by seamless cross-chain bridges will get us there and bring that vision to fruition.”
