Cross-Blockchain and Multi-Blockchain Bridge Exploits Cost $2 Billion in 2022; They Could Have Been Averted

The growth of DeFi in the last one year has made the need for Blockchain Bridges paramount. A cross-chain is an ability for two blockchains primarily separate from each other to talk to each other. In other words, it lets blockchains speak to each other because they are all built similarly. The risk at seven components in the bridge technology stack — noted on the graphic above — are described here.

Members are responsible for approving and overseeing network transactions. Committees are beneficial when multiple organizations share access to a network. The Arbitrum bridge offers a viable solution to Ethereum’s scalability issues, proving instrumental in enhancing transaction speed while reducing costs. As Layer 2 solutions continue to evolve, they hold the potential to impact the broader blockchain ecosystem by offering viable alternatives to existing scalability and cost constraints. Ethereum’s blockchain has a few scalability issues that can hinder its functionality.

What is a Blockchain Bridge?

If 50 blockchain networks get connected via a bridge and only one chain gets 51% attacked, the safety of 49 other platforms will be compromised as well. Asia-Pacific is expected to witness significant growth during the forecast period of 2022 to 2029 due to growth in development of blockchain network by BFSI, government and several retail industries within the region. The growing visibility of benefits of blockchain technology in the financial sector is also a significant contributor to the regional market expansion.

But just as translators bridge the gap between languages, the concept of blockchain interoperability emerges to weave these isolated ecosystems into a cohesive network. The hash time lock model effectively solves the trust problem inherent in the cross-chain process. As long as the initiator maintains confidentiality of the random number S and the time window, (T1 – T2) offers sufficient time for the responder to unlock the assets, both parties can realize a cross-chain transaction in a decentralized manner. To achieve interoperability across heterogeneous blockchain, several techniques have been developed. Here, we will present three technical solutions for cross-chain transactions, analyze their characteristics and discuss their potential risks.

Public Blockchain

Blockchain bridges are becoming an increasingly important part of the Web3 ecosystem as they allow different blockchain networks to interact with each other. One of the most important functions of a blockchain bridge is to facilitate token transfers from one blockchain to another. For example, with the help of a blockchain bridge a BTC holder could access Ethereum or another EVM-compatible network and use their assets to pursue opportunities in the largest dApp ecosystem out there. Bridges are extremely useful for dApp developers too, as they make sure that decentralized apps are not limited to a single network.

Scope for a Blockchain Bridge

Because bridges are still in their infancy, developers will hardly find any template for building and maintaining a secure bridge. What you have is different projects experimenting with different approaches, tradeoffs, and security mechanisms. If a new feature is introduced after deploying, then a new audit should be performed to ensure no errors are introduced. The Qubit Finance hack, for instance, occurred after the team introduced changes to the protocol without re-auditing the bridge contracts. But audits alone aren’t enough, as many protocols have been compromised even after multiple code reviews. One suggestion is to run a bug bounty program that incentivizes whitehat hackers to review a project’s code for critical errors and disclose them responsibly.

After a comprehensive review involving code evaluation and direct interaction with the bridge teams, the committee approved Wormhole and Axelar for Uniswap’s specific use case of protocol governance. Other bridges including LayerZero, Celer, DeBridge and Multichain did not meet the committee’s criteria. The report leaves open the possibility for some protocols to be reevaluated following future updates. Any given cross-chain bridge is a dApp that allows users to move assets between blockchains. Ensure secure interaction of off-chain components with blockchain networks with our comprehensive dApp audit.

The 5 Best Crypto Bridges

The operation of a federated bridge mirrors a private or permissioned blockchain. A protocol has to meet a set of criteria to qualify for a federation that manages bridge transactions. For instance, in a federated setup, some specialized nodes could be locking tokens on Blockchain A using secure multiparty computation. The entire blockchain space is still learning, growing, and developing. One thing’s for certain, blockchain bridges will be an integral part of the future. If brands and projects are limited to one blockchain, they’re limiting their reach.

They surely make the network user-friendly, allowing easy access to the network and building things along with moving assets. The conventional consensus mechanism or Proof of Work serves better security, although with additional expenses on energy consumption. Therefore, new blockchain networks have been evolving with the help of innovative consensus models, such as Proof of Stake.

  • This is because they use the “challenge and dispute” method; if a user believes that a transaction has been processed incorrectly, they can challenge the transaction and the bridge will investigate.
  • When the tokens are transferred back to the original network, the resembling tokens are burned or locked, and the same number of tokens are minted or unlocked in the adjacent blockchain.
  • The expansion of blockchain projects, such as in the DeFi landscape, creates the necessity for bridges.
  • One of the first things you need to do before you start looking for best blockchain bridges would be to find the definition of one.
