Security has been a vital challenge for decentralized finance (DeFi) and its evolution. Between 2020 and 2022, hackers stole over $2.5 billion via vulnerabilities on cross-chain bridges, Token Terminal information reveals. This is a considerable quantity in contrast with different safety breaches.
Issues with bridges have a root trigger: All of them have an “inherent vulnerability,” Theo Gauthier, founder and CEO of Toposware, instructed Cointelegraph. According to Gauthier, regardless of how safe a bridge is by itself, it’s “entirely reliant on the security of the chains it connects,” that means any breach or bug inside one of many two bridged chains makes the general bridge weak.
Briefly, bridges are used to attach totally different blockchains and goal to handle the shortage of requirements between protocols. Interoperability between blockchains is taken into account to be a vital purpose for enhancing the end-user expertise and selling broader crypto adoption.
Solutions for interoperability and safety in the crypto trade are gaining traction regardless of the bear market. One of the major applied sciences obtainable is zero-knowledge proofs (ZKPs), which permit information to be verified and confirmed as correct with out revealing additional data, not like typical interoperability options that require networks to reveal their states.

Through ZKPs, it is usually attainable to create a ZK-powered Ethereum Virtual Machine (EVM), famous Polygon’s chief data safety officer, Mudit Gupta. This would permit builders to launch scalable and utterly non-public Ethereum-compatible sensible contracts. Gupta additionally famous:
“We believe in the old crypto adage of ‘don’t trust, verify.’ With ZK-powered solutions, this is absolutely possible. The zkEVM has shown that it can maintain privacy, decentralization, speed and scalability. With this, there is no need to sacrifice anything that has made the crypto space what it is, and in fact, it improves it.”
For bridges, the answer could be auditing and real-time monitoring requirements, famous Gustavo Gonzalez, options developer at Open Zeppelin. Bridges’ sensible contracts “should be audited, ideally by multiple third parties, before being released ‘into the wild.’ New audits should happen anytime updates are made, and all results should be transparently shared with the community.”
Machine learning technology could also be used to flag potentially suspicious patterns of activity with advanced security monitoring, detecting an attack before it actually happens, said Gonzalez.
Combining security software solutions with blockchain protocols could make the entire space more secure for users and investors. A Bitcoin (BTC) maximalist would say “Just use Bitcoin, and you won’t have these issues at all.” While sensible contracts for Bitcoin are in the works, DeFi gamers will be tasked with constructing belief inside their respective ecosystems amid ongoing safety considerations.
