Continued from the previous article. PlatON Privacy-Preserving Computation White Paper | Part 4. Off-Chain Services This article is about the characteristics of applications on the privacy-preserving Computation network. 5 . Applications In this section, we generally describe several applications based on privacy-preserving capabilities. 5.1 Fair Exchange Fair exchange enables a seller and a buyer to exchange data securely. Security means that the buyer pays to the seller if and only if the buyer gets the digital goods. Theoretical result shows that it is impossible to exchange fairly without a trusted third…

Author : HaolanThe following content is a personal opinion and does not represent investment advice.If you like it, please comment, like and share! Foreword: Recently, there is a habitual “collective no speaking”.whether it is the policy guidance of the domestic blockchain industry, or various transaction pairs have opened a “declining channel”, giving everyone more reasons to reflect on previous wrong decisions . This point of view will combine recent market experience and PlatON’s new white paper outline “Decentralized Privacy-Preserving AI Networ 2.0” to elaborate on the three content directions of…

Since the PlatON white paper was released on 19 July 2018, and after nearly three years of continuous upgrades and improvements, PlatON has has grown into a distributed computing network infrastructure with complete architecture, leading features and excellent performance. In the PlatON network, privacy-preserving computation technology is the core engine supporting PlatON and Alaya networks, laying the cryptographic foundation of the PlatON privacy-preserving computation AI network. LatticeX Foundation aims to solve three main problems in the blockchain community, including privacy, storage and key management. The LatticeX Foundation has presented ideas…

Continued from the previous article. PlatON Privacy-Preserving Computation White Paper | Part 1. Overall Framework We have know about the Overall Framework of PlatON Privacy-Preserving Computation White paper, LatticeX Foundation proposes a framework, as shown in Figure 1, to deal with privacy and storage issues in PlatON/Alaya. This solution or plan is based on the architecture of PlatON 2.0. The vision of PlatON 2.0 is to build a decentralized and collaborative AI network and global brain to drive the democratization of artificial general intelligence. This chapter will cover the algorithm section…

Continued from the previous article. PlatON Privacy-Preserving Computation White Paper | Part 2. Algorithms Before reading this article, let’s review the Overall Framework of Privacy-preserving Computation. This article will introduce On-Chain Capabilities, including Privacy Payment, Privacy Computation, and Storage. Part.3 On-Chain Capabilities Privacy and storage are two important issues in blockchain. LatticeX Foundation focuses on the following aspects. 3.1 Privacy Payment transaction and smart contract are two basic components of blockchain. The privacy requirements and underlying solutions are different. 3.1.1 Payment It is worth pointing out that the main tokens in…

Continued from the previous article. PlatON Privacy-Preserving Computation White Paper | Part 3. On-Chain Capabilities This article will introduce Off-Chain Services, including Computation Service and Storage Service. Part.4 Off-Chain Services As discussed in previous sections, it is inevitable to provide computation and storage services to address the privacy and storage issues. The off-chain services are built upon layer 2 in PlatON 2.0. 4.1 Computation Service In layer 2 of PlatON 2.0, institutes or nodes with enormous amount of computation power could join the network to provide computation services as follows. Private…

Before we talk about the PlatON testing, we need to figure out the difference between blockchain testing and traditional Internet testing. That is mainly reflected in the blurring of the system boundary: the former is not only between the front-end API and a certain blockchain node but also among a large number of blockchain nodes. At the same time, it should be noted that the PlatON chain includes public chains and private chains that vary from each other in terms of management, user identity, the maximum number of nodes, etc….

Automatic testing generally refers to the test method of replacing manual testing with programs or tools. Compared with manual testing, automatic testing plays a great role in ensuring product quality and shortening test time with higher accuracy and better reusability. Here, the idea and the technical practice of PlatON’s automatic testing will be introduced in two parts. Multi-layer Automatic Testing The previous article centered on PlatON network automatic testing, and the peripheral products derived from privacy AI computing network, such as blockchain browser PlatScan and blockchain wallet ATON, we also…

What is Lumino? “Lumino” is the term of illumination. In PlatON and Alaya networks, Lumino is a Multi-Party Computation Ceremony, for creating the necessary security parameters of the zero-knowledge proof protocols. As one of the important privacy-preserving computation technologies, zero-knowledge proof (ZKP) allows a prover to convince a verifier that the he knows a secret information without directly disclosing the information itself. As a cryptographic primitive with both privacy protection and authentication capabilities, zero-knowledge proof is widely used in providing payment privacy, authentication privacy, and scalability. Most of ZKP protocols…

Automatic testing generally refers to the test method of replacing manual testing with programs or tools. Compared with manual testing, automatic testing plays a great role in ensuring product quality and shortening test time with higher accuracy and better reusability. Here, the idea and the technical practice of PlatON’s automatic testing will be introduced in two parts. Why Implement Automatic Testing In the world of PlatON, there are various statuses, such as staking status, locked status, proposal status, etc. Among them, the staking status of a node can be divided…

Background of DID As we’ve discussed in the previous article, until the advent of blockchain technology, DIDs did not develop that quickly. The emergence of blockchain has solved the biggest problem of DID. As the blockchain technology is tamper-proof, and with the characteristics of the hash, it enabled the establishment of an identity system that is identification unique, credible, and decentralized. Nowadays, compared with the popular concepts of blockchain technologies such as scaling, cross-chain, and DeFi, DID is not a research hot spot. Up to now, only a few teams…

Nowadays, the Internet is ubiquitous as nearly 70% of the world’s population uses the Internet in their daily lives. Digital life and real life are blended with a variety of Internet applications and services through computer devices. Users can instantly interact with different individuals or companies distributed around the world all the time. During the interaction, the convenience and importance of digital identities for linking and mapping of real identities online and the automatic verification and process of digital identities are becoming increasingly significant. This time’s special feature will be…

We thank to all the registered contributors for joining this activity to provide security guarantees. This document aims to give a detailed explanation and a step-by-step guidance for contributors to accomplish the ceremony. The Process Registration There will be a registration phase through the whole ceremony. Contributors can choose one or both of the underlying elliptic curves, BLS12–381 and BN254, to participate. Note different zero knowledge proof systems based on Plonk could use different underlying curves. A back-end server will start the ceremony based on a list of all registered…

To help community partners and technology enthusiasts better understand the Lumino ceremony, We have prepared a Q&A session on the 60-day secure multi-party computing ceremony. A) ABOUT LUMINO Q1. What is Lumino? PlatON/Alaya will build a decentralized privacy-preserving infrastructure based on Zero-Knowledge Proof (ZKP). However, in most of the existing high-efficiency ZKP algorithms, system parameters need to be created in a centralized manner, and the centralized third party that creates the parameters can forge the certificate, which will destroy the security of the underlying level of PlatON/Alaya. Lumino is designed…
