A cross-chain bridge is a sort of technology that enables several Blockchain networks to communicate and interact with one another. The system allows for the transfer of assets like bitcoins from one Blockchain to another.. And without the requirement for a centralized middleman.
One of the primary advantages of cross-chain bridges is the capacity to increase the usefulness and valuation of Blockchain assets. Allowing these assets to flow freely between networks enables their use. And in a broader range of applications and obtain more liquidity. This can also aid in the promotion of interoperability and collaboration across various Blockchain initiatives. Resulting in the creation of a more robust and inclusive ecosystem.
Cross-chain bridges enable numerous new operations. However, hackers have caused security problems by hacking these applications. Because of the technical characteristics of cross-chain bridges. It’s better to utilise them only if you fully comprehend how they function and what you are doing to avoid unanticipated crypto failures.
This post will examine five types of cross-chain bridges currently under development. As well as their distinct characteristics and capabilities.
Portal Token Bridge (formerly Wormhole)
Portal has become one of the most popular cross-chain bridges in the industry. This decentralised bridge was first built on the Solana Network to allow bidirectional cryptocurrency token exchanges across Solana and Ethereum. Portal has evolved into a multichain network that links seven of DeFi’s leading blockchains, including Solana, Ethereum, BSC, Polygon, Terra, Avalanche, and Oasis, together contributing to 88% of the Defi company. Portal uses particular network participants defined as Guardians to provide customers with the highest suitable cross-chain trade functionality. Supervisors monitor bridge activity and evaluate client requests. When a client requests the transfer of a crypto token from one chain to another. Guardian nodes destroy the fixed amount of tokens on the first chain.
Atomic Switching Bridges
These bridges employ atomic swaps, a sort of smart contract, to permit asset transfers between Blockchain networks. Atomic swaps enable cross-chain trade that is rapid, safe, and trustless. Each participating Blockchain technology network in the trade generates a smart contract to carry out the operation. The smart contracts distribute assets to different entities only after both parties fulfill their obligations This reduces the need for a centralized middleman while lowering the danger of fraud.
Sidechain Bridges
These bridges link two or more distinct blockchains, known as sidechains, to a central Blockchain. Sidechains are autonomous blockchains that are linked to the main Blockchain by a two-way peg. This enables the movement of assets between the sidechain and the primary Blockchain. The major advantage of sidechain bridges is the capacity to expand the main Blockchain without sacrificing its security or decentralization. Sidechains can also be customized for particular use cases, including high-throughput trading or privacy-enhancing functionality.
Hash Time-Locked Contracts Bridges
This bridge facilitates cross-chain transactions by utilizing hash time-locked contracts (HTLCs). HTLCs is a sort of smart contract that enables the transmitter to construct a payment that the receiver may only redeem if they supply appropriate cryptographic evidence. This approach guarantees that assets are moved securely and without trust. The primary advantage of HTLC bridges is their capacity to communicate blockchains with varying degrees of security and decentralization and their capability for off-chain transactions.
The Harmony Bridge
Harmony, a platform for decentralized apps, offers a LayerZero bridge that allows digital wallets to be transferred across the Ethereum, Binance Smart Chain, and Harmony systems. Customers may transfer their ETH and BNB tokens to the Harmony Blockchain to obtain the related assets. The commodities transferred can be retrieved at any time.
Every form of cross-chain bridge possesses its own set of characteristics and skills. The individual use case and needs will determine which one to employ. Atomic swap bridges are appropriate for permissionless cross-chain trade, sidechain bridges aid in growing the primary Blockchain. HTLC bridges facilitate off-chain transactions. And Harmony bridges sync incompatible blockchains with trustworthy nodes.
Conclusion
Cross-chain bridges remain in the initial stages of development. However they possess the capability to transform how we utilize Blockchain technology completely. They can assist in boosting the use and significance of Blockchain assets and encourage interoperability between various projects. By facilitating the frictionless transfer of assets across different networks. Cross-chain bridges will become an increasingly essential role in the growth of the Blockchain ecosystem as technology advances.
