Understanding Cross-Chain Bridges

Share your love

Blockchains are now recognized as a potentially revolutionary technology in a variety of fields, including supply chain tracking and healthcare, as well as the underlying technology for cryptocurrencies such as Bitcoin. The widespread interest in blockchain technology has generated a number of research and development activities. However, the blockchain market is highly fragmented, and customers have to choose from a variety of incompatible or poorly compatible networks: present protocols and standards do not provide 100% interoperability between a huge number of blockchains that exist on the market.

Interoperability refers to a distributed ledger technology (DLT) design's ability to receive and exchange data with external systems. Cross-chain technology enables data exchange between DLT designs or external systems, hence promoting interoperability.

The concept of cross-chain technology adds tremendous value to services available to blockchain developers and users. Cross-chain bridges can help crypto enthusiasts by providing support for several blockchain variations and help taking the value of smart contracts, NFTs, and tokenization outside the Ethereum blockchain to different networks.

The evolution of cross-chain token production has created a plethora of opportunities. Developers can now combine the strengths of many blockchains to develop applications with unrivaled capabilities. Consider DeFi platforms that smoothly interact with assets from many chains, or non-fungible tokens (NFTs) that may be traded across multiple blockchains. Cross-chain development also promotes innovation by allowing developers to try out new consensus mechanisms and governance structures.

Cross-Chain Bridging in Crypto: A Wider Range of Opportunities

Cross-chain bridges allow for interactions between various blockchain networks. Currently, blockchains exist primarily as segregated networks incapable of properly communicating and sharing data with one another. For example, Ethereum users cannot build smart contracts on the Bitcoin network, and Bitcoin holders can’t use their tokens to conduct transactions on the Ethereum network. Cross-chain bridges connect individual blockchains, enabling the transfer of assets and information between them. They have emerged as one of the available solutions that are being used to connect different blockchains and ecosystems within the crypto space.

Before blockchain bridges, you’d have to rely on the services of centralized exchanges (CEXs) like Binance or Coinbase if you want to use a particular asset on another blockchain. A cross-chain bridge would allow you to convert and use your crypto on a particular network without having to go through a time-consuming process on a CEX. It works by encapsulating tokens in a smart contract and then issuing native assets that may be used on any other blockchain of choice.

Blockchain bridges enable customers to reduce transaction costs while improving their user experience. Imagine having to go through many exchanges every time you want to swap a token. Aside from the greater fees connected with doing this every time, the whole process of connecting and transferring funds between two different blockchains is quite cumbersome. A cross-chain bridge connects users to alternate platforms, allowing them to leverage features that the original blockchain may lack.

In addition, cross-chain bridges benefit developers since they enable the creation of cross-chain apps and allow application users to engage with the same dApp across several chains. If a network is crowded, customers can move to another chain to improve their dApp user experience (UX). As a developer, on-chain liquidity is important to the success and popularity of your dApp project. The issue is that most new-generation alternatives to Bitcoin or Ethereum are less popular and liquid.
Cross-chain bridges, on the other hand, enable dApp developers to tap into liquidity accessible across many chains. These applications allow users to transfer funds between different blockchains, allowing value to flow across many platforms. Some cross-chain bridges boost interoperability by facilitating the movement of tokens across independent blockchains. Developers can integrate such bridges into dApps to increase available liquidity.

Cross-Chain Swaps and Their Importance

Simply put, cross-chain swaps are a method for trading a token issued on one blockchain for a token issued on another blockchain in a trust-minimized way. While users can already access cross-chain swap functionality via centralized exchanges, this adds multiple layers of friction (e.g., transferring tokens to an exchange, swapping them directly or indirectly through a medium of exchange such as USD, and then returning the swapped tokens to a wallet on a different blockchain). Furthermore, this method compels customers to engage custodial services and temporarily relinquish control of their possessions. For something as basic as a cross-chain swap, this becomes a significant impediment to constructing a world fueled by sovereign digital asset ownership.

In the rapidly expanding world of cryptocurrency, seamless and secure cross-chain transactions are vital. Cross-chain swaps provide a suite of benefits to crypto traders:

  • Lower fees. The absence of a third party generally reduces transaction costs.
  • Cross-chain interoperability. Users can exchange assets from different blockchains without losing assets or private keys’ custody.
  • No fiat currency is involved. Crypto users can exchange assets without utilizing fiat currency as a baseline value.
  • Faster speeds. Transactions are executed swiftly since the smart contract automatically executes once each party does its part.
  • Enhanced security. The smart contracts involved offer higher security since users can regain their assets if the other party fails to perform as agreed.

Challenges and Solutions in Cross-Chain Transactions

In their current form, cross-chain swaps present several challenges to users. They can be burdened with technical complexities: atomic swaps (i.e swaps that enable P2P transactions between parties wishing to exchange cryptocurrencies on different blockchain networks) require exchanging hashed cryptographic information. This closes the door to traders who lack the technical knowledge to understand such details and those with privacy concerns.
In addition, atomic swaps are only possible for cryptocurrencies belonging to networks with similar cryptographic hashing algorithms limiting the options for traders. Moreover, the atomic swapping process comprises more steps than trading on a centralized exchange. To top it off, cross-chain swaps don’t allow crypto to fiat exchanges: a user will have to look for an alternative.

There are a number of solutions on the market that try to handle the various hurdles that prevent blockchains from achieving complete compatibility. However, before we explore them a bit more, it’s important to understand the following: blockchain implementations, by definition, are decentralized, running on dispersed networks powered by consensus algorithms. Essentially, they function in silos, which means that Blockchains such as Ethereum, Bitcoin, and Ripple cannot communicate directly. This lack of compatibility is a key barrier to the widespread proliferation and adoption of blockchain technology. However, some networks are trying to overcome this issue.

Polkadot is a well-known example of a multi-chain platform that enables different blockchains to interact. Polkadot's relay chain provides security, and attached parachains can execute transactions concurrently, considerably enhancing scalability. As a result, the utility of a certain crypto asset is expanded outside its native network, resulting in the formation of a symbiotic ecosystem.

Cosmos, another well-known cross-chain network, uses a slightly different interfacing mechanism; each blockchain in the Cosmos ecosystem functions autonomously but can interface with other Cosmos blockchains via Inter Blockchain Communication (IBC).

Additionally, there are a number of popular cross-chain bridges that enable swaps between different blockchains. These are:

  • Wormhole. Wormhole is a popular cross-chain bridge that enables the transfer of tokens between the Ethereum and Binance Smart Chain networks. Everstake serves as a validator for Wormhole, ensuring the security and integrity of cross-chain transactions.
  • Axelar. Axelar is a cross-chain communication protocol that facilitates interoperability between various blockchains. Everstake acts as a validator for Axelar, enabling smooth and secure cross-chain transfers for users.
  • Orbit. Orbit is a decentralized bridge connecting various blockchain networks, allowing for the seamless transfer of assets. As a validator for Orbit, Everstake ensures the reliability and trustworthiness of cross-chain transactions through this bridge.
  • Binance. Coming from the world’s leading exchange, Binance Bridge is an Ethereum-BNB Smart Chain Bridge that allows anyone to convert into and from the BNB Smart Chain and other BSC-compatible formats. At the time of writing, the Binance Bridge supports the conversion of ERC-20 tokens along with coins on other networks like XRP, LINK, ATOM, DOT, XTZ and ONT.
  • Avalanche. The Avalanche Bridge is a two-way cross-chain bridge between Avalanche and the Ethereum network. It uses ChainSafe’s ChainBridge to enable two-way transfers of both crypto tokens and non-fungible tokens (NFTs).
  • AnySwap. Like the Avalanche Bridge, Fantom’s AnySwap is a bi-directional solution that facilitates cross-chain transfers between the Ethereum Network and the EVM-compatible Fantom Network. AnySwap offers a multi-chain liquidity solution that employs liquidity pools to facilitate cross-chain swaps. The liquidity pools that have been implemented across several blockchain networks make it easier to move funds to Fantom from Ethereum, Avalanche, Polygon, and BNB Chain.
