With bridges being hacked en masse, could there be a better solution to the blockchain industry’s interoperability issues?
According to Hacken’s Web 3 Q1 and Q2 reports, more than $85 million worth of cryptocurrencies were compromised through hacks on bridging services in the first half of 2024. While this is a sharp decline from full-year bridge service losses in 2023 – $337.72 million – safety concerns surrounding bridges persist. Can there be better solutions for blockchain interoperability and improved cross-chain technologies than bridges? And if so, how do these technologies intend to solve the problems facing bridging services?
In this piece, we’ll take a closer look at the issues facing traditional blockchain bridges, the rise of new and improved cross-chain technologies, and how they improve blockchain interoperability and communication.
Why bridging services may soon become redundant
Blockchain bridges, or application-specific cross-chain bridges, were introduced in 2021 at the height of the DeFi boom, enabling communication between blockchains. These protocols are designed to facilitate the transfer of assets and information from one chain to another. They were created to solve the problem of interoperability and the siled nature of blockchains.
Over the years, chain-specific bridges have emerged as an essential solution for value transfer and communication between blockchains. These protocols function by locking users’ tokens in the source chain and then creating intermediate tokens in the destination chain. However, bridges have proven to be vulnerable, as explained above, with major hacks and theft of user funds hampering the solutions they provide.
In addition to hacks and security issues, application-specific bridges also face the following challenges:
- Security Issues: One of the biggest challenges cross-chain bridges face is their susceptibility to hacks and theft. Whether custodial or non-custodial, bridges have been a ripe target for hackers in the blockchain space. Since 2022, bridge services have lost nearly $2.5 billion in customer money due to hacks, punctuated by Ronin Bridge’s $625 million loss in March 2022. Whether targeted by the centralized custody services or a… smart contract exploit, bridges will continue to suffer from hackers.
- Time consuming: Second, using bridges requires users to wait a while before withdrawing their tokens to the source chain. For example, using the Arbitrum bridge, it will take a user about a week to get their tokens back to the source chain, without using a third-party service. Using a third-party service may take less time, but comes with security risks.
- UX challenges: Moreover, the current bridges are a problem for new, non-experienced crypto users. For example, imagine a user who wants to run a DApp on Solana using SOL tokens, but owns USDC on Ethereum. The user might need to pack and unpack assets, download another wallet native to Solana, and find a market for the packed tokens in order to successfully use SOL tokens on Solana. These multiple processes use gas charges and can sometimes be expensive for the user.
The complexity and safety issues surrounding current application-specific bridges make it difficult to gain widespread acceptance of the innovation. Bridges can only be a partial solution to the growing challenges of Web 3 interoperability. But for the growing blockchain and DeFi landscape, cross-chain solutions must not only be efficient, but also enable seamless capital flow for all users.
Zeus Network, a bridgeless platform using the Solana blockchain, aims to provide better solutions for interoperability between blockchains. The platform leverages Solana for its lightning-fast, affordable and reliable qualities, as well as the Zeus Layer, a plug-in and programmable network of nodes on the Solana Virtual Machine (SVM), to make liquidity available on all blockchain networks – the source and destination chains.
The rise of bridgeless cross-chain technology
Zeus Network is a pioneer in bringing bridgeless cross-chain technology to the DeFi landscape. DApps’ limited interoperability with certain blockchain networks results in fragmented liquidity, less innovation, and less-than-ideal user experiences. Zeus Network aims to solve these challenges by providing a permissionless and bridgeless layer, starting with a connection between Bitcoin and Solana. The platform leverages Bitcoin’s robust security and Solana’s effectiveness, speed, and low transaction fees to give DApps on Solana access to Bitcoin’s vast liquidity pool.
Developers can create a wide range of applications on the Zeus Network and connect them to Solana and Bitcoin, unlocking a world of possibilities, from DeFi apps to secure and efficient financial services. Zeus has developed a monolithic architecture that consolidates execution, data availability, and consensus within a single framework, enabling seamless integration and a unified user experience across the ecosystem.
So how does bridgeless architecture design work?
First, chain-agnostic transactions (on Bitcoin or Solana) are proposed by Zeus Nodes and then submitted to the Zeus program states. The transactions are then signed and merged at the Zeus layer via the Zeus Programming Library (ZPL), a suite of SVM programs built on Solana Virtual Machine. ZPL is a verifiable interface that allows developers to build on top of the Zeus Network. The signed transactions are then sent to the destination chain.
To protect transactions and secure cross-chain communications, honest Zeus Nodes can simply submit fraud proofs to destroy malicious proofs. This ensures that communication between the chains remains secure.
Unlike bridges, Zeus Network ensures that no party can game the system, hack into centralized custody, or abuse the smart contract as you could be cut off. Moreover, the process of transferring assets from Bitcoin or Solana is simple and fast, with every step performed on one platform.
Last words
The need for better interoperability and cross-chain technologies is crucial to the overall growth of the blockchain industry. While traditional blockchain bridges have played a crucial role in enabling cross-chain communication, their vulnerabilities and inefficiencies highlight the need for more advanced solutions. The rise of bridgeless platforms like Zeus Network represents a significant leap forward in blockchain interoperability.
Streamlined, efficient, fast and cheap alternatives like the Zeus Network could be the key to unlocking dormant liquidity through blockchain networks. This could be the emergence of a potential new standard for the future of decentralized finance and cross-chain technology.
