# 2. Challenges in Cross-Chain Interoperability

In the current blockchain ecosystem, the lack of cross-chain interoperability not only restricts the interaction of assets and applications across different chains but also introduces significant security risks. Cross-chain bridges, a key technology for transferring assets between chains, have been prone to security vulnerabilities, leading to substantial asset losses. According to data from Rekt ([https://rekt.news/leaderboard/](https://rekt.news/leaderboard/)), bugs or errors in cross-chain solutions have resulted in billions of dollars in stolen assets.

In response to this pressing issue, developing a secure, decentralized cross-chain solution has become crucial. Ola's BTC cross-chain solution is designed to address these challenges, offering a safer, trust minimized cross-chain platform with advanced ZK Soft Verification technology.
