BOLT has introduced zero-knowledge proof technology, which allows data to be audited without revealing privacy. We believe that the foundation of trust lies in the witnesses, and only when a sufficient number of witnesses are established can the system's credibility be tested. In a fully-functioning society, trust is also inevitably built on mutual supervision among members that is open and transparent. Any machine with internet connectivity and a certain amount of storage space can serve as a packaging node for BOLT and receive block rewards. Users can vote for trusted nodes by staking BOLT, and once there are enough trusted nodes, they can sequentially audit the packaged blocks and receive service rewards.
The essence of zero-knowledge proof is ‘how to prove that one has certain information without revealing the content of that information to others.’ For example, a user needs to prove that they have the password to a safe without revealing any confidential information to a third party. With zero-knowledge proof technology, the user can open the safe and display the unlocked contents as proof of ownership of the password, without disclosing the password to anyone. By integrating this concept with blockchain, BOLT can ensure privacy and security while being monitored by the blockchain ecosystem, without revealing any sensitive information about the enterprise's operations or data. This not only enhances privacy and security but also boosts user trust.
Hybrid chain evidence is generated by compressing the off-chain evidence of several transactions into an encrypted hash value, which is then saved on both Ethereum and Bitcoin through cross-chain protocols. It can be used for cross-chain querying, usage, and verification. When users transfer assets between different blockchains, the unique hash value generated by the hybrid chain proof let both Ethereum and BOLT can verify the transaction, proving that the assets have not been tampered with or double-spending, ensuring the validity and legitimacy of each transaction, and achieving a higher level of data security and correctness.
