Blockchain
A blockchain is a decentralized, distributed ledger that records transactions in digital blocks connected through cryptography. Each new block must be validated by the network through a process of verification and consensus before being added to the chain. This validation process ensures security and transparency without the need for a central authority. Advantages of blockchain technology include increased transparency through an openly viewable record of transactions, enhanced security through encryption, and decentralization that avoids single points of failure. Examples of blockchain applications include decentralized social networks, marketplaces, and ridesharing platforms that operate without central operators by leveraging blockchain and cryptocurrency technologies.
Beyond the Metaverse: XV (eXtended meta/uni/Verse)
Beyond the Metaverse: XV (eXtended meta/uni/Verse)
Abstract: We propose the term and concept XV (eXtended meta/omni/uni/Verse) as an alternative to, and generalization of, the shared/social virtual reality widely known as ``metaverse''. XV is shared/social XR. We, and many others, use XR (eXtended Reality) as a broad umbrella term and concept to encompass all the other realities, where X is an ``anything'' variable, like in mathematics, to denote any reality, X ∈ {physical, virtual, augmented, ...} ℝeality. Therefore XV inherits this generality from XR. We begin with a very simple organized taxonomy of all these realities in terms of two simple building blocks: (1) physical reality (PR) as made of ``atoms'', and (2) virtual reality (VR) as made of ``bits''. Next we introduce XV as combining all these realities with extended society as a three-dimensional space and taxonomy of (1) ``atoms'' (physical reality), (2) ``bits'' (virtuality), and (3) ``genes'' (sociality). Thus those working in the liminal space between Virtual Reality (VR), Augmented Reality (AR), metaverse, and their various extensions, can describe their work and research as existing in the new field of XV. XV includes the metaverse along with extensions of reality itself like shared seeing in the infrared, ultraviolet, and shared seeing of electromagnetic radio waves, sound waves, and electric currents in motors. For example, workers in a mechanical room can look at a pump and see a superimposed time-varying waveform of the actual rotating magnetic field inside its motor, in real time, while sharing this vision across multiple sites.

Ppt on blockchain technology
Blockchain is a specific type of database where information is collected in blocks that are chained together, forming a chain of data known as the "blockchain." Each new block of information contains a reference to the previous block, linking them together in a way that makes tampering very difficult. Transactions are transmitted across a peer-to-peer network of computers, validated through solving equations, and collected into blocks that are added to the blockchain, forming a permanent record of all transactions.

Distributed learning of deep neural network over multiple agents
https://www.sciencedirect.com/science/article/pii/S1084804518301590
Otkrist Gupta, Ramesh Raskar,
In domains such as health care and finance, shortage of labeled data and computational resources is a critical issue while developing machine learning algorithms. To address the issue of labeled data scarcity in training and deployment of neural network-based systems, we propose a new technique to train deep neural networks over several data sources. Our method allows for deep neural networks to be trained using data from multiple entities in a distributed fashion. We evaluate our algorithm on existing datasets and show that it obtains performance which is similar to a regular neural network trained on a single machine. We further extend it to incorporate semi-supervised learning when training with few labeled samples, and analyze any security concerns that may arise. Our algorithm paves the way for distributed training of deep neural networks in data sensitive applications when raw data may not be shared directly.Asset Tokenization - An Introduction and Overview, Guest Lecture at SMU

What is corda
In the beginning itself, the blockchain was mostly heard for its possible applications in the financial domain. Bitcoin started it, and now most of the existing financial infrastructures are attracted towards the blockchain technology. Many of the financial institutions already started to implement blockchain assisted technologies. Consequently, more finance domain specific blockchain development platforms also came into existence. Corda is one of them
Food Traceability using Blockchain
This document discusses using blockchain for food traceability. It notes that consumers demand more transparency in the food supply chain but find food producers untrustworthy. Blockchain could address this by providing trust, transparency and tamper-resistance. A consortium blockchain from companies in the supply chain may be better than a public blockchain due to privacy needs. Several blockchain platforms are outlined as options. Challenges for adoption include integrating distributed systems and ensuring authentication of participants and compliance with privacy laws like GDPR. Several pilot projects are underway to explore blockchain for traceability.
Types of Blockchains
There are four different types of blockchain - Public blockchain, Private blockchain, Consortium blockchain and Hybrid blockchain.
This presentation gives a glimpse about blockchain technology and the different types of blockchain. Hope it helps!

Where It All Started
Blockchain technology was first introduced in a whitepaper entitled: “Bitcoin: A Peer-to-Peer Electronic Cash System,” by Satoshi Nakamoto in 2008.
No reliance on trust
Digital signatures
Peer-to-peer network
Proof-of-work
Public history of transactions
Honest, independent nodes control majority of CPU computing power
Nodes vote with CPU computing power
Rules and incentives enforced through consensus mechanism

Cryptocurrency Summarized
Bitcoin was the first digital, i.e., cryptocurrency
A maximum of 21 million Bitcoins can be generated
Just as with real world mining, energy must be invested to solve complex mathematical problems by which systems earn Bitcoins
https://www.cryptocoincharts.info/coins/info claims to be indexing 4,220 cryptocurrencies
Most circulated: Bitcoin, Ethereum, Litecoin
*
The Technology Behind Bitcoin
Think of Bitcoin as an electronic asset (as well as a digital currency)
A network of computers keeps track of Bitcoin payments, and adds them to an ever-growing list of all the Bitcoin payments that have been made, called “The Bitcoin Blockchain”
The file that contains data about all the Bitcoin transactions is often called a “ledger”
Bitcoin value is created through transaction processing, referred to as “mining,” which is performed by distributed processors called “nodes” of the peer-to-peer network
A Gentle Introduction to Bitcoin by Antony Lewis, https://bravenewcoin.com/assets/Reference-Papers/A-Gentle-Introduction/A-Gentle-Introduction-To-Bitcoin-WEB.pdf
*
Mining Evolution
Mining is the process whereby value is created through transaction processing that occurs on nodes of the network.
In 2009, one could mine 200 Bitcoins with a personal, home computer. In 2015, it would take about 98 years to mine just 1 Bitcoin.
Today there is almost no money to be made through traditional home mining.
ASIC (Application Specific Integrated Circuit) has been designed strictly for mining Bitcoins.
Groups of miners have formed mining pools, with each being paid their relati ...
