IPFS Powers the Distributed Web

InterPlanetary File System

IPFS allows users to host and receive content in a manner similar to BitTorrent . As opposed to a centrally located server, IPFS is built around a decentralized system ^[5] of user-operators who hold a portion of the overall data, creating a resilient system of file storage and sharing. Any user in the network can serve a file by its content address, and other peers in the network can find and request that content from any node who has it using a distributed hash table (DHT).

In contrast to BitTorrent, IPFS aims to create a single global network. This means that if two users publish a block of data with the same hash , the peers downloading the content from "user 1" will also exchange data with the ones downloading it from "user 2". ^[6] IPFS aims to replace protocols used for static webpage delivery by using gateways which are accessible with HTTP . ^[7] Users may choose not to install an IPFS client on their device and instead use a public gateway. A list of these gateways is maintained on the IPFS GitHub page. ^[8]

RPC Blockchain-based Service Network

Tue, 05 Jul 2022 01:11:42 GMT

Blockchain-based Service Network

RPC

RPC(Remote Procedure Call) is a set of protocols and interfaces that the client interacts with blockchain system. The user can query the blockchain related information (such as block number, blocks, node connection, etc.) and send the transaction request through RPC interface.

RPC nodes provide a link between blockchains and the decentralized applications (dApps) that run on top of them. Web3 wallets have default RPC node providers so users can easily start interacting with web3 applications, however, sometimes these default, public RPC nodes cause problems for everyday users and web3 developers due to slow network speeds, incorrect blockchain data, and unreliable service (uptime).

In this article we’re going to explain why it is a good idea to create a private RPC endpoint, and how to add one to your MetaMask wallet so you can get faster speeds, accurate data, and more reliable service.

In the context of this article, the term “private RPC endpoint” means a personal RPC endpoint that is not publicly available for everyone else to use. We do not mean that the transactions sent through your personal RPC endpoint are private transactions, that they will settle privately, or that they will not appear in the public mempool.

What are the benefits of using a private RPC endpoint ?

Using a private RPC endpoint has many benefits including speed, accurate data, more reliable service, and less competition when submitting transactions during periods of high transaction volumes like an exclusive NFT drop.

Here are some of the use cases where traders, developers, and everyday users could benefit from updating their MetaMask wallet from the default RPC endpoint to a personal one:

Sending transactions during an exclusive, first-come-first-serve NFT mint.

Sending transactions to capitalize on time-sensitive arbitrage opportunities.

Getting reliable service when other node providers experience degraded service during airdrops.

There are multiple reasons why web3 users stand to benefit from creating a private RPC endpoint and updating their default web3 wallet settings to send transactions through a personal RPC endpoint.

A Security Analysis of Blockchain-Based Did Services

Sun, 22 May 2022 08:27:38 GMT

Decentralized identifiers (DID) has shown great potential for sharing user identities across different domains and services without compromising user privacy. DID is designed to enable the minimum disclosure of the proof from a user's credentials on a need-to-know basis with a contextualized delegation. At first glance, DID appears to be well-suited for this purpose. However, the overall security of DID has not been thoroughly examined. In this paper, we systemically explore key components of DID systems and analyze their possible vulnerabilities when deployed. First, we analyze the data flow between DID system components and analyze possible security threats. Next, we carefully identify potential security threats over seven different DID functional domains, ranging from user wallet to universal resolver. Lastly, we discuss the possible countermeasures against the security threats we identified.

What are the Benefits of Blockchain in Real Estate?

Commercial real estate constitutes a significant portion of world economic asset and transaction activity. According to an MSCI report, the size of the professionally managed global real estate investment market increased from $7.4 trillion in 2016 to $8.5 trillion in 2017. Today’s real estate market however, consists of many siloed and independent networks with transactional friction and opacity between existing systems. The Ethereum blockchain presents a practical solution to realize the following industry benefits:

Tokenization of real estate assets

Process efficiency for underlying industry operations

Reduced costs from process automation

Access to global asset distribution

Access to broader investor pools due to ownership fractionalization

Access to secondary market opportunities

Data accessibility to increase transparency and inform better investment decisions and portfolio management

Blockchain for Electronic Voting System—Review and Open

Research Challenges

Electoral integrity is essential not just for democratic nations but also for state voter’s

trust and liability. Political voting methods are crucial in this respect. From a government

standpoint, electronic voting technologies can boost voter participation and confidence

and rekindle interest in the voting system. As an effective means of making democratic

decisions, elections have long been a social concern. As the number of votes cast in real life

increases, citizens are becoming more aware of the significance of the electoral system .

The voting system is the method through which judges judge who will represent in political

and corporate governance. Democracy is a system of voters to elect representatives by

voting . The efficacy of such a procedure is determined mainly by the level of faith

that people have in the election process. The creation of legislative institutions to represent

the desire of the people is a well-known tendency. Such political bodies differ from student

unions to constituencies. Over the years, the vote has become the primary resource to

express the will of the citizens by selecting from the choices they made .

Using blockchain to drive supply chain transparency

Future trends in supply chain

New technologies are presenting promising opportunities for improvement across the supply chain. Using blockchain in the supply chain has the potential to improve supply chain transparency and traceability as well as reduce administrative costs.

Monitor advancements

A blockchain supply chain can help participants record price, date, location, quality, certification, and other relevant information to more effectively manage the supply chain. The availability of this information within blockchain can increase traceability of material supply chain, lower losses from counterfeit and gray market, improve visibility and compliance over outsourced contract manufacturing, and potentially enhance an organization's position as a leader in responsible manufacturing.

Deloitte recommends: Using blockchain in the supply chain can help participants record price, date, location, quality, certification, and other relevant information to more effectively manage the supply chain.

Personal identity security

Sun, 22 May 2022 05:34:40 GMT

Personal identity security

Technological advancements in the digital space has revolutionized every aspect of our lives, from shopping to collaborating with colleagues to keeping in touch with friends to entertainment to managing our finances.

Since the dawn of the Internet, identity management has been a key concern, with billions of dollars being spent on usability, security and privacy.

The identity and access management market is expected to grow from $8.09 billion in 2016 to $14.82 billion by 2021, representing a 12.9% CAGR.

Despite this huge investment, managing digital identities continues to be plagued by three Cs – Cumbersome, Costly and Challenging.

With data driving the world today, digital identity is critical to most business and social transactions.

This governs the interaction of users in the digital world.

But traditional identity systems continue to be highly vulnerable, with single points of failure, attracting continuous attempts to gain access to the complete repository of high value data.

And, with companies prioritizing cybersecurity, identity protection and compliance management, while customer experience is significantly compromised.

As individuals, we shoulder the burden of managing multiple online IDs and passwords, while also handling a host of documents, including passports, driver’s licenses, Social Security cards and medical insurance cards.
