# 3.5 Application of ZK Technology

The Ola team’s deep experience in ZK technology powers Ola. ZK technologies such as Plonky2/3 and Binius play a significant role in enhancing Ola’ design. In particular, ZK Soft Verification technology is widely applied in Ola, especially in chains like Bitcoin that cannot directly deploy ZK verifiers. Through Soft Verification, the Massive user network guarantees the finality and trustworthiness of cross-chain operations.This innovative mechanism positions Ola ahead of other cross-chain solutions in terms of security and decentralization, offering users a trust minimized environment for cross-chain transactions.
