PlatON: A High-efficiency Trustless Computing Network Founded by China’s Crypto ‘Godfather’
January 28, PlatON, the pioneering global privacy-preserving computing network has completed its Version 0.4.0 upgrade and began to support Verifiable Computation (VC) based smart contract. Since then, PlatON becomes the world’s first computing network uses the VC algorithms to build layer2 in order to solve scalability problems.
The technologies behind PlatON’s include Verifiable Computation (VC) and privacy-preserving computation, which are made by various cryptographic algorithms like MPC (secure Multi-Party Computation), Homomorphic Encryption (HE), etc.
As the growing demand for data transaction, commercially available IT technologies are radically below the level of trustworthiness that is desired. At this point, trustless computing provides a new solution for data privacy protection.
Xiao Feng, a prestigious economist, and entrepreneur in China is also honored as the “godfather” of the Chinese crypto industry. He also acknowledged the importance of trustless computing in boosting blockchain application.
“Trustless computing has become a worldwide topic as the rise of artificial intelligence (AI). At present, China has not been lagged behind in this field,” said Xiao.
He has founded PlatON in July 2018. In a digitalized world with a massive amount of data generated constantly, PlatON is designed to provide secure data sharing & connection in different structures from multiple sources, with strong privacy protection.
PlatON has launched its first testnet Baleyworld vision 0.3.0 on December 18, 2018. ”We are very excited to announce this achievement that leads us closer to a world of maximum data monetization.” Sun Lilin, CEO of PlatON, mentioned in an interview: ”Nowadays the so-called big data are actually small because they are owned and separated by different companies and institutions. In such scenarios can trustless computing be helpful in linking and encouraging different parties to share and use data without privacy breach.”
Many industries are expected to benefit from the monetization of data harnessed by PlatON technology while being fully compliant with the General Data Protection Regulation (GDPR), which comes into effect on May 25, 2018, in EU.
As we all know, the data transaction is the core of digital asset. However, only using blockchain technology for data privacy is not enough, the cryptography is the key to solve this kind of problem.
Verifiable Computation in PlatOn
PlatON uses VC to achieve scalability, verifiability, and privacy in trustless computing. Moreover, as privacy is concerned in many trustless computing cases, MPC and HE are employed to prevent exposure throughout the entire lifetime of the data.
PlatON is aiming to construct a full stack infrastructure for decentralized apps, while individual module such as VC will be available to connect another blockchain to PlatON network for scalable and privacy-preserving computing.
A publicly VC scheme consists of a set of three polynomial-time algorithms. The triple of algorithms of a VC is required to satisfy properties including correctness, unforgeability, and efficiency.
In PlatON, two additional features are required in its VC scheme: the worker-efficiency, which is relatively efficient for a worker to generate a correctness proof for a function value, and no Trusted Setup procedure would be involved.
Trustless Computing in PlatON
PlatON requires no external setup and compared to previous VC or Zero-Knowledge Proof (ZKP) solutions, it significantly shortens proof size and enables accelerated proof generation and verification. It is accomplished using full homomorphic encryption (FHE) and secure multi-party computation (MPC) which jointly guarantees the privacy of the input data and computing logic.
The trustless computing on PlatON relies on trusted hardware or TEE (e.g. SGX) provided by a third-party manufacturer for computing integrity that depends on falsifiable cryptographic assumptions and providing unprecedented security of private data through its lifetime without a trust boundary.
The CEO indicated that the final vision that PlatON aiming to achieve is to become the next generation of high-performance, scalable, privacy protected, decentralized cloud computing network.
At present, PlatON is still in its first stage “Baleyworld”, and its development roadmap show the other three stages to the success: Trantor (Q3, 2019), Terminus (Q4, 2019), and Gaea (Q2, 2020). All these four stages are inspired by Isaac Asimov’s renowned science fiction, the Foundation series.
