As cryptocurrency continues to gain popularity, ZIL Token (Zilliqa), as an emerging blockchain platform, is facing many challenges and opportunities. This article will delve into future research directions for the ZIL token, specifically its potential in post-quantum cryptography and scaling through parallel processing.
1. Challenges of post-quantum cryptography
With the rapid development of quantum computing technology, traditional asymmetric cryptography is facing unprecedented threats. As the latest version of Zilliqa, ZQ2 implements a pluggable cryptography design, which means that the current encryption scheme can be replaced as needed in the future. This design not only improves the flexibility of the system, but also provides security for the future.
However, while the NIST-standardized post-quantum signature scheme is suitable for authentication of transactions and consensus messages in terms of signature and verification times, its signature size makes it impractical for current applications. In particular, there is a lack of efficient signature aggregation methods, which is essential for Zilliqa’s consensus algorithm.
For example, when using the lattice-based Dilithium signature scheme, the signature size reaches 2.7 KB, which would increase the transaction size by an order of magnitude. For each validator's signature, if there are 31 validators in the committee, 21 signatures will eventually need to be stored, with a total size of 56.7 KB, which is an increase of two orders of magnitude compared to the 96 bytes of BLS signatures. This signature length trade-off and lack of signature aggregation is not limited to lattice-based schemes, but also includes other stateful hashing-based schemes such as XMSS and LMS.
2. Expansion through parallel processing
Parallel smart contract execution has been one of Zilliqa’s core technologies since its inception. Zilliqa’s research team has developed a static code analysis tool called CoSplit that is able to infer the properties required for parallel scheduling of transaction execution. The design of this tool is based on an important insight: if a transaction operates on different parts of the state, or if the operations are commutative, then its effect does not depend on the order of execution.
Unlike ZQ1, ZQ2 requires multi-threaded execution of transactions in each x-shard block. This demand requires Zilliqa to continuously innovate in parallel processing technology to ensure the efficiency and security of its transactions. Through parallel processing, Zilliqa is able to support more transactions and increase overall network throughput without affecting performance.
3. Future Prospects of ZIL Tokens
The future development of ZIL tokens not only relies on technological advancement, but also requires community support and ecosystem expansion. With continued research into post-quantum cryptography and parallel processing technology, Zilliqa is expected to occupy a place in the future blockchain market.
Future ZIL tokens may achieve breakthroughs in the following aspects: Security improvement: Through the implementation of post-quantum cryptography, Zilliqa will be able to resist potential threats brought by quantum computing and ensure the security of users' assets.
Transaction efficiency: Further optimization of parallel processing technology will enable Zilliqa to support higher transaction volumes, reduce transaction delays, and improve user experience.
Ecosystem expansion: As more developers and companies join the Zilliqa ecosystem, it will promote the birth of more innovative applications, thereby increasing the utility and value of ZIL tokens.
4. Conclusion
Overall, the future of ZIL token is promising. With continued research into post-quantum cryptography and parallel processing technology, Zilliqa will play an increasingly important role in the development of blockchain technology. Facing future challenges and opportunities, Zilliqa's team will continue to work hard to provide users with more secure and efficient blockchain services.
The future ZIL token will not only be a digital asset, but also an ecosystem full of innovation and opportunities. With the advancement of technology and the support of the community, Zilliqa's vision will gradually be realized and become the leader in the blockchain field.
