Why is Filecoin different? IPFS founder talks about its proof system

Source: IPFS Force Zone Compilation Original link: Like other large technological innovations, blockchain is a combination of several mature technologies that we have used and trusted for decades. The "consensus mechanism" has been studied since the 1970s and developed into a tool to combat spam in the 1990s. It allows users in distributed systems […]

Technical direction: Bandwidth optimization in transaction forwarding (1)

Early blockchain systems tended to have low throughput and correspondingly low bandwidth requirements. The consensus protocol itself was the bottleneck of their performance. For example, the Bitcoin network only generates 1MB blocks every 10 minutes, which is almost negligible in today's broadband network environment. In recent years, with the development and maturity of new-generation blockchains […]

Technical Perspective | How easy is it to implement BTC double payment with the RBF protocol?

On December 18, the portal issued an informal notice explaining why merchants who accept BTC should switch to BCH: "Dangerous flaws" were discovered in the BTC software. The issue is related to the length of the confirmation of the BTC-based RBF agreement, which provides individuals with the opportunity to double spend on merchants. […]

Dry Goods | Basic Principles of Chainlink Predictor

In this article, we will briefly describe the basic principles of Chainlink technically. If you explain what Chainlink is in the shortest sentence, you can say that Chainlink is a decentralized oracle project, so in order to understand the working principle of Chainlink, we must first understand what a oracle is. Oracle Oracle in English […]

ODIN (Open Data Index Name)-Open Data Index Name Identification Technical Specification. The protocol was called by the project party (PPk Pub): "The ODIN logo protocol is an […]

Introduction to Technology | Understanding Bulletproofs of Zero-Knowledge Proof Algorithms: Range Proof II

Foreword In the first article of this series, we introduced the application of Bulletproofs to Range proof. When the prover wants to prove that the value of v is in the range [0, 2 n -1], he needs to send 2n + 7 elements. However, this type of O (n) CC is not what we […]

Technical Guide | Building IPFS Applications with Node.Js

Source: Translation: Interstellar Introduction IPFS is a game changer. In contrast to today's networks, IPFS can actually implement a distributed, permanent network. Most importantly, it may be interplanetary, which is completely impossible with our current client-server architecture. IPFS utilizes a peer-to-peer architecture where each node is both a client and a server. If you […]
