Deep Dive Review into Grin (March 2019)
Everything you need to know about the cryptocurrency Grin, a blockchain that uses the Mimblewimble protocol to provide extra privacy. Learn more: https://crushcrypto.com/grin-analysis/ Project website: https://grin-tech.org/ Original whitepaper: https://download.wpsoftware.net/bitcoin/wizardry/mimblewimble.txt Andrew Poelstra’s whitepaper: https://download.wpsoftware.net/bitcoin/wizardry/mimblewimble.pdf Join the official Crush Crypto Telegram channel for our latest publications and updates: https://t.me/joinchat/AAAAAESrVCwzd19x1DvDOQ Download the PDF version of the presentation: https://crushcrypto.com/wp-content/uploads/2019/03/Crush-Crypto-Deep-Dive-Review-into-Grin.pdf Download the free ICO Guide which contains 6 simple steps for analyzing any ICOs to find the winning projects: https://crushcrypto.com/youtube/ Note: This is not a paid review. We do not offer promotional or advertising services. Our content is based on our own research, analysis and personal opinion. _______________________________________ What is Grin? Grin is an open source blockchain that uses the Mimblewimble protocol to provide extra privacy. Mimblewimble is a protocol where transactions can be cryptographically verified despite hiding the amount that is being sent. To read more about Mimblewimble, refer to our article on cryptography and privacy. _______________________________________ Token Economics As of March 6, 2019, the circulating supply of Grin is 4,336,260 with a market cap of $14 million. The rate of new Grin coins being released is 60 per block, or 1 every second. This rate is likely to remain constant forever, meaning the inflation percent will decrease every year as the circulating supply grows. After 10 years, the inflation rate will fall below 10% - after 20 years, below 5%. In 25 years, Grin will have a 4% inflation rate, comparable to Bitcoin’s rate 10 years after its creation. Additionally, the Grin team has cited multiple studies to estimate that 2% or more of Grin tokens will be lost from circulation each year. _______________________________________ Strengths - Mimblewimble is a promising privacy protocol that completely shields transaction information from any third parties. It also allows for transactions to be verified while storing minimal data on the blockchain, which means Grin is a highly scalable blockchain. - Grin launched with no ICO, no pre-mine, and no allocation for the founders, which may be viewed positively in the crypto community and discourage speculators. - The open-source project is being developed by a highly competent group of developers. - The token economics of Grin are straightforward and ensure the inflation rate will decrease every year. - Even though Grin is a young project, it has already developed a decent community and exposure among the cryptocurrency space, with multiple solid exchanges (Poloniex and Bittrex) listed the coin. _______________________________________ Weaknesses - It has been seen with Bitcoin that having no true leadership can lead to long disputes over how to update the blockchain, and this could be an issue for Grin going forward. - Since there is no fundraising, Grin developers rely on donations to fund the project. If such donations eventually stop coming in, the Grin developers will have to volunteer their time to work on the project. - Grin has a lot of competition in the market as privacy coins like Zcash and Monero have a first-mover advantage, larger communities, and more widely known privacy protocols. - The future of privacy coins in general is still uncertain.There is also significant uncertainty with respect to government regulation that could make it hard for Grin to thrive. - The diluted market cap for Grin is very large right now. According to Messari, Grin is the 7th most valuable cryptocurrency using coin supply at year 2050, higher than both Monero and ZCash. _______________________________________ Disclaimer The information in this video is for educational purposes only and is not investment advice.

DAO- Decentralized Autonomous Organizations: Can You Trust a Blockchain?
Speakers: Clément Epié (Cellabz) Primavera de Filippi (CNRS/Harvard) Moderator: Benjamin Tincq (OuiShare) This session will address the question of trust (or "trustlessness") and how it relates to the question of human autonomy and agency. Decentralized Autonomous Organizations (DAOs) are organizations operated on blockchain-based smart contracts which aim at removing the need for control measures to ensure trust. Can you trust a DAO that is completely autonomously operated? If not, can you trust the people who are operating it? How can a "trustless" technology like the blockchain bridge the gap between these 2 figures? How much agency should be given to a DAO? How to ensure that it does not take away human agency? http://ouisharefest.com

Cube is the blockchain security platform for autonomous car. The key to Blockchain is that technology ensures trust. Cube uses block-chain technology to ensure the security of autonomous mobile networks. These days, the car is a mass of software with over a million lines of code. Cars started to use more networks, and autonomous cars should depend on the network heavily for self driving. It uses network navigation route, traffic information, vehicle to vehicle information, and remote ECU upgrade. This means that autonomous vehicles have a greater risk of being hacked. Perhaps no one has ever suffered from a hacking virus once or twice. However, if a self-propelled vehicle is hacked, it can be a huge risk. Cube creates a security system that protects these autonomous vehicles from hacking. Unlike past methods that did not prevent hacking, we use blockchain technology. Applying blockchain is not a hack at all, unless you hack hundreds of thousands of computers at the same time. Cube uses blockchains, artificial intelligence, and Quantum Hash Cryptography technology. Welcome to WWW.ICOLINK.COM || https://icolink.com ||- ICO LINK LISTING, NEWS BLOG & COMMUNITY.

Amir Taaki: Using Technology to Reconstruct the Social Moral Fabric
https://amirtaaki.org/ https://twitter.com/Narodism Amir Taaki Developed the first alternative bitcoin implementation First UK Bitcoin exchange Worked on Dark Wallet & Dark Market projects leading to open bazaar Join the YPG in Syria Is now Based in Barcelona Is there a central problem that drives your actions? The main issue in society today is a social problem not an economic one. There is a fundamental lack of meaning in life We are participants in a giant machine Isn't this the price we pay for specialization, the tool that has enabled human civilization to prosper? Yes, there is a system of subdivision of human labor into specializations. At the same time we have a sense of nihilism, apathy & selfishness. An aspect of society has been lost We have reduced everything to what can be measured We need to bring back something ancient within ourselves So you are saying that we have lost part of our humanity to our means of production . . . Yes, some would argue that the ability to meaningfully change your environment is lower that ever We generally lack autonomy Freedom from responsibility is the absence of true freedom Today we over value growth In the past people used to read Dostoyevsky for enjoyment. Today the most popular fiction is about a boy on a broomstick There is no sense of applying ourselves to a work that extends beyond our lifetimes How do we remedy the situation? Can you suggest a grand goal? We have to think about what is the purpose of society To birth a higher type of human being There used to be an ideal of the renaissance man, a well rounded capable person We need to change our view of humans from being an incentivised cog in the machine How does the movement that has rallied around blockchain compare to this? Technology is a power of shaping the world around us It is up to us to employ technology for sociological change We need to take this technology to arm people to realise a new societal paradigm Your description has violent themes in opposition to the culture here (the Devcon 4 conference) which seems to be focussed on building rather than fighting. Behind the rhetoric there is a world that is seeing a rise of right wing dictator like figures and religious fundamentalism. There is also a large amount of human suffering This technology will not be a technology of liberation for the west Just like happened with Marx, where people took his ideas from the west and used them to reshape their societies, we will see these technologies applied to developing nations. People led through desperation to make active use of these technologies What technologies do you mean specifically Technologies for social organization Making decisions Sharing information Collaborating on projects Financial and economic activity Culture and education These are not technologies, they are areas where technology might have an impact They are the main areas of human society Politics Law Self defence Culture Economy We need to find a way to tough these areas with technology These are realms of human coordination. Why is technology now being applied to these problems? A lot of cryptography was developed in the 8-0s and 90s but did not make their way into public consciousness Bitcoin managed to being them to libertarians and open software developers It was a form of uncontrollable peer to peer money This got people thinking about bigger implications This brought people to deeper technologies and looked for way to recombine fields of research that had never been applied to the real world The real value is less in blockchain, it is the large volume of young people who want to change the world The most important objective is to have a vision of where we want to go and to use these pieces to get there So where do we want to go? The most important problem is increasing public participation Reconstructing the moral fabric of society How can a technology reconstruct a moral fabric? Technology by itself cannot change people's mentality It can be a powerful tool to enable movements that want to change things The Kurdish people want to create a new societal paradigm based on direct democracy and individual empowerment Developing technologies that enable social coordination

Blockchain 101 Ep 21 - The digital signature of Bitcoin
The digital signature can only be generated by the Bitcoin sender. It’s a series of tamper-proof code. By verifying this code, it proves that the transaction was initiated by the sender and not altered during the process. Digital signature employs Digital Digest and Asymmetric Cryptography. Digital Digest compresses the information to a fixed length of code, then uses the private key to encrypt it, forming a digital signature. After completion, it groups the transaction message with the signature and send it to the miners. Miners use the sender’s public key for verification. If it’s valid, it means he did initiate the transaction and it remains unaltered. Asymmetric cryptography refers to using the private key for encryption and public key for decryption. It seems complicated but all you need to do is to enter the private key and voilà!. Watch the video here! Huobi Pro will post a question in our Tweet via our Twitter account (https://twitter.com/Huobi_Pro) each time we put up an episode of Blockchain 101 post on our Twitter account, we will randomly select 20 people who answered in the format [UIDxxxxxxxx, correct answer] and retweet our post will be entitled to 1 HT each.

Bitcoin Q&A: The obsoletion of legacy systems
How will the traditional financial system adapt to cryptocurrencies? Legacy systems (banks, like horse-and-carriage) are delaying the inevitable. Some people will see the future earlier than others and leave banks. How do we ensure that Bitcoin remains an open and decentralised system in the face of enterprise encroachment? What is at stake? How the internet killed the phone industry. Bitcoin's killer app is about changing how money works. Etheruem is about reinventing the modern corporation. These questions are from the Polish Bitcoin Congress (Polski Kongres Bitcoin) Warsaw, Poland, the HoshoCon event, and the October Patreon Q&A session, which took place on May 12th, October 11th and October 27th 2018, respectively.

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Autonomous Mobile Mesh Networks Mobile ad hoc networks (MANETs) are ideal for situations where a fixed infrastructure is unavailable or infeasible. Today’s MANETs, however, may suffer from network partitioning. This limitation makes MANETs unsuitable for applications such as crisis management and battlefield communications, in which team members might need to work in groups scattered in the application terrain. In such applications, intergroup communication is crucial to the team collaboration. To address this weakness, we introduce in this paper a new class of ad-hoc network called Autonomous Mobile Mesh Network (AMMNET). Unlike conventional mesh networks, the mobile mesh nodes of an AMMNET are capable of following the mesh clients in the application terrain, and organizing themselves into a suitable network topology to ensure good connectivity for both intra- and intergroup communications. We propose a distributed client tracking solution to deal with the dynamic nature of client mobility, and present techniques for dynamic topology adaptation in accordance with the mobility pattern of the clients.

DEF CON 22 - Ladar Levison and Stephen Watt - Dark Mail
Slides Here: https://defcon.org/images/defcon-22/dc-22-presentations/Levison-Watt/DEFCON-22-Levison-Watt-Dark-Mail-UPDATED.pdf Dark Mail Ladar Levison FOUNDER OF LAVABIT, LLC Stephen Watt LEAD DEVELOPER, REFERENCE IMPLEMENTATION, DARK MAIL Data privacy and anonymity have long been cornerstone interests of the computer security world, but not particularly important to the general public. News events in the past year have seen the political climate shift radically, and now data privacy has become big business with secure mail solutions being the focal point of this new found attention. Dark Mail is not the only solution in the secure mail space, but just as Lavabit’s preoccupation with privacy and user autonomy was a rarity when it started over a decade ago, it hopes once again to push mail security forward into a new frontier. It is Dark Mail's objective to achieve the highest degree of security possible - with the introduction of an interoperable mail protocol as an open standard. To that end, we are publishing documents describing the protocol, along with a reference implementations of the client and server under a free software license. What most of the secure email systems in the privacy race have prioritized in tandem are ease of use for the masses, and cryptographically secure encryption of message contents between a sender and recipient. Additionally, they tend to place trust for private key management and encryption in the hands of the end user, and not the mail server. While this would certainly be an improvement over traditional SMTP, it leaves much to be desired. Where do other solutions fall short? Metadata. Dark Mail is designed to minimize the leakage of metadata so that ancillary information like subject lines, recipients, and attachments doesn’t fall into the hands of curious third parties. That means all information about the mail and its contents are completely opaque to everybody but the parties communicating - including the servers handling the messages in transit. Accomplishing these goals wasn’t possible using existing standards, which is why we created a security enhanced flavor of SMTP for mail delivery dubbed DMTP. What separates dmail from competing secure mail designs is the level of security it affords the user while retaining its simplicity of use. We have automated the key management functions, so complex cryptography operations are handled without user interaction. Of equal importance is the need for an implementation that is open to peer review, security audits, and cryptanalysis. Unlike many commercial solutions, dmail isn’t tethered to a single centralized provider; instead it offers the ability for anybody to host secure mail services. Like today, users will be able to access their mail from anywhere, using a web client with client-side encryption, or a traditional client application on their mobile or desktop device for an even greater degree of security. An open standard will guarantee that users have the freedom to adopt any dmail-compatible client or server implementation of their choosing. Most attendees of this presentation will be familiar with the curious story of Lavabit's demise. While Lavabit's hosted mail service refused to surrender unfettered access to its users' secrets, this course of action may not be the obvious choice for network administrators placed in similar situations. Most digital surveillance efforts require the service provider to be complicit with the wiretapping requests of law enforcement. Dmail aims to protect messages from surveillance and tampering - whether it be subversive or coerced - by placing that capability beyond the reach of service providers. With dmail the keys belong to the user, and the message decryption occurs on the user’s device. Even so, users can choose how much to trust a service provider - with standardized modes that reside at different points along the security vs usability spectrum.

George Musser: "Spooky Action at a Distance" | Talks at Google
Over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time: nonlocality - the ability of two particles to act in harmony no matter how far apart they may be. Einstein grappled with this oddity and couldn't come to terms with it, describing it as "spooky action at a distance." More recently, the mystery has deepened as other forms of nonlocality have been uncovered. This strange occurrence, which has direct connections to black holes, particle collisions, and even the workings of gravity, holds the potential to undermine our most basic understandings of physical reality. If space isn't what we thought it was, then what is it? In this talk "Spooky Action at a Distance: The Phenomenon That Reimagines Space and Time--and What It Means for Black Holes, the Big Bang, and Theories of Everything", George Musser sets out to answer that question, offering a provocative exploration of nonlocality and a celebration of the scientists who are trying to explain it. He traces the often contentious debates over nonlocality through major discoveries and disruptions of the twentieth century and shows how scientists faced with the same undisputed experimental evidence develop wildly different explanations for that evidence.

Stanford Computer Forum: Applications of VRF by Dominic Williams (String Labs)
Dominic Williams, CTO of String Labs, presents at Stanford Computer Forum on applications of Verifiable Random Function (VRF). = Abstract = We argue that a source of unmanipulable and unpredictable random values provides the most effective means to drive and organize decentralized networks and their higher-level applications. We demonstrate this idea by introducing two ingenious systems. Firstly we review how a network can use a “Threshold Relay” system that applies unique deterministic threshold signature cryptography (Dan Boneh’s BLS signature scheme) as a VRF to produce such a sequence of random values, further exploring how a robust high performance blockchain can be built upon the framework. Then we review how a network created using Threshold Relay can host “smart contract” software implementing an autonomous commercial banking system that applies generated randomness to give out loans algorithmically. String Labs is currently incorporating both methodologies into the DFINITY and Phi projects.

USENIX Enigma 2018 - Least Privilege: Security Gain without Developer Pain
Travis McPeak, Sr. Security Engineer at Netflix The principle and benefits of Least Privilege are long established in Computer Security—dating back to the 1970s. Despite this it is far from universally adopted. Technologies used to define and enforce Least Privilege policy are arcane to most in the computing industry. Software developers are incentivized to ship products and features, so they focus on what helps them work fast: wildcards in policies, if they even have one. Traditional attempts to counter this typically require system administrators or security staff to perform manual reviews and craft security policies in response. As application complexity and development velocity increase it becomes impractical to manually determine Least Privilege ahead of time. A central policy gatekeeper doesn't scale efficiently and is likely to negatively impact delivery velocity. Our approach at Netflix combines gathering data about how applications interact with their environment and automatically adjusting the permissions in their security policy. Unused permissions are automatically removed from application policies across our environment without manual effort from developers or the security team. This approach gives us the best of both worlds: the security team gets least privilege policies and developers maintain high velocity. During this talk we’ll describe how this works in our environment, challenges we’ve overcome along the way, and recommend other applications for the same methodology.

The Third Industrial Revolution: A Radical New Sharing Economy
The global economy is in crisis. The exponential exhaustion of natural resources, declining productivity, slow growth, rising unemployment, and steep inequality, forces us to rethink our economic models. Where do we go from here? In this feature-length documentary, social and economic theorist Jeremy Rifkin lays out a road map to usher in a new economic system. A Third Industrial Revolution is unfolding with the convergence of three pivotal technologies: an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet, all connected to the Internet of Things embedded across society and the environment. This 21st century smart digital infrastructure is giving rise to a radical new sharing economy that is transforming the way we manage, power and move economic life. But with climate change now ravaging the planet, it needs to happen fast. Change of this magnitude requires political will and a profound ideological shift.

An Introduction to Private Machine Learning - Singapore Python User Group
Speaker: Satish Shankar This talk will introduce the essential concepts from cryptography necessary to build AI systems that use sensitive data and yet protect our privacy. Specifically, we will cover concepts from secure multi-party computation (MPC) and how they can be used to build machine learning algorithms. Why does this matter? This matters because we as a society are struggling to balance the benefits of data driven systems and the privacy risks they create. Building any machine learning or analytics model necessitates the collection of data. If this data is sensitive or personal, it inevitably turns into an honeypot for hackers. At a societal level, we are responding to this issue by introducing more regulation such as the GDPR. Instead of regulations, it is possible to use cryptography to protect our data and still analyse it: This talk show how. About: Shankar leads the machine learning and AI efforts for Manulife’s innovation labs. He works on quantitative investment and insurance, drawing on a wide range of fields from machine learning, natural language processing, differential privacy, encryption, and more. He is particularly interested in the intersection of blockchains, distributed systems and privacy in machine learning.

USENIX Enigma 2018 - Anatomy of Account Takeover
Grzegorz Milka, Software Engineer, Google With billions of usernames and passwords readily accessible via the black market, account takeover poses a significant threat to services that rely solely on passwords for authentication. In this talk, we provide a deep dive into the ecosystem supporting account takeovers, the danger it poses to users, and the importance of automatic, defense-in-depth risk detection systems as a fundamental defense in identity solutions. We start by exploring the relative likelihood that users fall victim to data breaches, phishing, or malware using a dataset of over 3.3 billion stolen credentials; and how hijackers subsequently use these credentials for spam, financial theft, and stepping-stone attacks. We then turn to examine how identity providers can use risk analysis, in conjunction with ‘login challenges’, to bridge the security gap between two-factor authentication and password-only users with minimal additional friction. We show the practical weaknesses of certain login challenges (SMS and email) and evidence of attackers now collecting risk profile data and challenge responses to weaken user security. Finally, we discuss ongoing challenges such as how public opinion (as measured by our user studies) may be at odds with actions identity providers should take to improve overall account security, and how the industry should try and change this.

6 Things You Didn't Know About a Blockchain
Blockchain explained! Here’s how to understand the blockchain & the technology behind Bitcoin & cryptocurrency. A blockchain is essentially a super secure form of record-keeping. It’s made up of a list of digital transactions, information, data, or whatever else you can think of, that are grouped together in “blocks” then added to a row of past blocks to form a “chain,” hence the name “blockchain.” What powers the blockchain is a network of computers (or nodes) working together to verify each transaction & adding it to the chain of blocks so it’s viewable to the public & can’t be changed or edited retroactively. This makes it virtually impossible for human error to ever occur, therefore ensuring the blockchain’s long-lasting integrity. Blockchains operate autonomously, meaning they’re self-governed & their actions are carried out without any outside control or influence whatsoever. In the case of Bitcoin, it solves the problem of double-spending by ensuring that each unique transaction doesn’t occur more than once. Like I said earlier, data on the blockchain is resistant to any modifications. The only time it can be retroactively altered is when a majority of the computers in the network agree to let these modifications take place. But doing so consequently alters subsequent blocks. If I wanted to send you $1,000 using a traditional bank wire, I’d have to pay between $35-$45 in fees & wait between 3-5 business days for you to get your money. It’s because blockchain technology’s autonomous nature allows for transactions to take place directly from one person to another without the need for third-party services to regulate the transaction. It simply facilitates the transaction for cheaper & faster. It’s also extremely secure. Not only is its foundation based on cryptography, but its decentralized nature means there’s no single access point in which hackers can exploit it, making vulnerabilities within the system practically non-existent. Basing it in one specific location makes it “centralized.” Blockchains are “decentralized,” meaning their information is stored on thousands, if not, millions, of network computers all across the globe. Any hacker looking to taint the data would have to access each & every one of these computers at the same exact time! Ledgers based on blockchain technology are also open & public, making them easily verifiable. Anyone can view any transaction for any amount at any time, while still keeping user identity anonymous. Additionally, it’s designed to check in with itself in a sort of self-auditing manner. Satoshi Nakamoto was the first to conceptualize & implement blockchain technology when he introduced Bitcoin to the public. As I said before, the Bitcoin blockchain is upheld by a network of nodes that verify each & every transaction in a process as “mining.” Mining involves setting up a computer & connecting it to Bitcoin’s blockchain network using a client designed specifically for validating & relaying transactions. Once connected, the computer is automatically required to download a copy of the entire blockchain. It’s at this point that the computer can begin solving complex mathematical puzzles to verify transactions in a process called “proof-of-work.” Once a puzzle has been solved, the transaction is added into a block, a new copy of the ledger is distributed to the entire network, & the miner is rewarded with a certain amount of Bitcoin. Now, say you’ve sent me 1 BTC, the transaction has been verified, & it’s been added to the latest block; since then, another newer block has been created & added to the chain. It’s said that the block in which our transaction can be located is “1 block deep.” Most merchants & exchanges won’t consider the transaction confirmed until it’s 6 blocks deep or more. Doing so prevents any possibility of double-spending from occurring. These days, a new group of BTC transactions is accepted & formed into a block every 10 minutes on average. There are currently over 1,100 new cryptocurrencies available, most of which use different technology. Bitcoin’s primary function is a transfer of value directly from one person to another...but that’s just the tip of the iceberg. One such other cryptocurrency is Ethereum, which we’ll discuss in further detail later since it warrants its own video. To give you the gist of it though, Ethereum allows for smart contracts to function & also acts as a platform for developers to create & deploy other decentralized applications aka “Dapps.” Storj will take your photos, break each photo up into smaller files, encrypt each file for safety & security purposes, then distribute them to be stored across other hard drives within the Storj network.

DEF CON 23 - Mahdi Namazifar - Detecting Randomly Generated Strings
Numerous botnets employ domain generation algorithms (DGA) to dynamically generate a large number of random domain names from which a small subset is selected for their command and control. A vast majority of DGA algorithms create random sequences of characters. In this work we present a novel language-based technique for detecting strings that are generate by chaining random characters. To evaluate randomness of a given string (domain name in this context) we lookup substrings of the string in the dictionary that we’ve built for this technique, and then we calculate a randomness score for the string based on several different factors including length of the string, number of languages that cover the substrings, etc. This score is used for determining whether the given string is a random sequence of characters. In order to evaluate the performance of this technique, on the one hand we use 9 known DGA algorithms to create random domain names as DGA domains, and on the other hand we use domain names from the Alexa 10,000 as likely non-DGA domains. The results show that our technique is more than 99% accurate in detecting random and non-random domain names.

Computable Real Numbers and Why They Are Still Important Today
Talk by ACM A.M. Turing Laureate Edmund Clarke during the ACM A.M. Turing Centenary Celebration, June, 2012. Abstract: Although every undergraduate in computer science learns about Turing Machines, it is not well known that they were originally proposed as a means of characterizing computable real numbers. For a long time, formal verification paid little attention to computational applications that involve the manipulation of continuous quantities, even though such applications are ubiquitous. In recent years, however, there has been great interest in safety-critical hybrid systems involving both discrete and continuous behaviors, including autonomous automotive and aerospace applications, medical devices of various sorts, control programs for electric power plants, and so on. As a result, the formal analysis of numerical computation can no longer be ignored. This talk focuses on one of the most successful verification techniques, temporal logic model checking. Current industrial model checkers do not scale to handle realistic hybrid systems. The key to handling more complex systems is to make better use of the theory of the computable reals, and computable analysis more generally. New formal methods for hybrid systems should combine existing discrete methods in model checking with new algorithms based on computable analysis. In particular, this talk discusses a model checker currently being developed along these lines.

DEF CON 24 - Jake Kambic - Cunning with CNG: Soliciting Secrets from Schannel
Secure Channel (Schannel) is Microsoft's standard SSL/TLS Library underpinning services like RDP, Outlook, Internet Explorer, Windows Update, SQL Server, LDAPS, Skype and many third party applications. Schannel has been the subject of scrutiny in the past several years from an external perspective due to reported vulnerabilities, including a RCE. What about the internals? How does Schannel guard its secrets? This talk looks at how Schannel leverages Microsoft's CryptoAPI-NG (CNG) to cache the master keys, session keys, private and ephemeral keys, and session tickets used in TLS/SSL connections. It discusses the underlying data structures, and how to extract both the keys and other useful information that provides forensic context about connection. This information is then leveraged to decrypt session that use ephemeral cipher suites, which don't rely on the private key for decryption. Information in the cache lives for at least 10 hours by default on modern configurations, storing up to 20,000 entries for client and server each. This makes it forensically relevant in cases where other evidence of connection may have dissipated. Bio: Jake Kambic is a DFIR researcher and network penetration tester

Article 370 of the Indian constitution is an article that gives autonomous status to the state of Jammu and Kashmir. The article is drafted in Part XXI of the Constitution: Temporary, Transitional and Special Provisions. In politics and government, a spoils system (also known as a patronage system) is a practice in which a political party, after winning an election, gives government civil service jobs to its supporters, friends and relatives as a reward for working toward victory, and as an incentive to keep working for the party—as opposed to a merit system, where offices are awarded on the basis of some measure of merit, independent of political activity.

SingularityNET Whitepaper | 1.4 A Decentralized Self Organizing Cooperative
1.4 A Decentralized, Self-Organizing Cooperative One can think about SingularityNET as a “Decentralized Self-Organizing Co- operative.” This is a similar concept to the better-known DAO (“Decentralized Autonomous Organization”), but is not quite the same, because in the case of SingularityNET there is a Foundation structure that will provide high-level oversight. As the network evolves over time it is intended to have the capability to evolve into a truly decentralized and autonomous organization. This sort of organization is distinguished from an ordinary corporation, above all, by its openness. At its foundation, SingularityNET is a set of smart contract templates which AI Agents can use to request AI work to be done, to exchange data, and to supply the results of AI work. These also include contracts to be used by external, non-AI Agents who wish to obtain AI services from AI Agents in the network. Anyone can create a node (an AI Agent) and put it online (running on a server, home computer or embedded device) and enter this node into the network, so that it can request and/or fulfill AI tasks in interaction with other nodes, and engage in economic transactions. SingularityNET can be accessed through its own token, the AGI token. Token holders can mainly purchase goods and services in the marketplace and in future could be part of the democratic governance process on specific governance issues. During the initial phases of the network’s operation, the core parameters of the SingularityNET’s operation will be regulated by a nonprofit Foundation, whose activities will be advised and monitored by a Supervisory Board. The Foundation will operate the network and be responsible for oversight to prevent abuse and hostile behavior, while obviously respecting the privacy of the particulars of inter-agent interactions. However, beyond this ’high-level oversight, even in the early stages the detailed day-to-day operations of SingularityNET will be purely self-organizing, emerging in a bottom-up way from the activities of the AI Agents involved (including e.g. the creation of new AI Agents by the existing pool of AI Agents, and the insertion of these new AI Agents into the network). In short, SingularityNET is a radically innovative economic mechanism, designed to catalyze human and machine intelligence toward a new form of ethically beneficial self-organizing intelligence. The SingularityNET of AI Agents is designed to provide valuable AI services to customers across the Internet, while, in the process, self-organizing toward its lofty goals. A highly successful SingularityNET may very plausibly play a major role in the transition of humanity toward a positive Technological Singularity. Critically, SingularityNET is as much about the quest to do good as it is about the quest to create increasingly intelligent systems. The SingularityNET project is designed to generate an intelligent global economy that pursues maximized benefits for all people, and for all life. Through a combination of powerful AI Agents, human decision-making, and a benefit-maximizing architecture, SingularityNET will accelerate the development of a global supermind, helping humanity evolve into a more advanced, intelligent, beneficial, and connected mode of being. The growth of SingularityNET will foster advances not only in practical AI algorithms and structures, but also in the general theory and practice of beneficial Artificial General Intelligence, in the design and analysis of structures for ethically intelligent economies, and in the continuous refining of means to conceptualize and estimate “benefit” and “greater good”.

Secure, private & encrypted file transfer - Fairdrop
https://fairdrop.xyz/ - This video is a demonstration on how to send files through Fairdrop. Our world is becoming increasingly digital and our freedom is at stake. The Web of today is plagued with aggressively expanding profiteering surveillance practices, design choices that erode our agency, invasive tracking, obnoxious advertising, centrally controlled services and an exploitive economy that’s almost completely removed from our sight. To a pessimist it may look like privacy has become an obsolete notion during the Web 2.0 reign, drowned by “free” services. Fortunately, that is not the case. We are starting to see the value of online privacy. There are more and more tools that help us protect it and they are increasingly based on a new logic. One that puts privacy, security and anonymity first. Fairdrop is the first dapp based on Fair Data Society principles We want to be among the contributors to this new paradigm. That’s why we would like to present to you the Fairdrop file transfer dapp. It’s the first blockchain dapp by Fair Data Society based entirely on the Fair Data Society principles. These principles make privacy its No. 1 feature without sacrificing user experience. Fairdrop is not just a theoretical concept but a concrete decentralized service that wants to take its centralized counterparts head on. (Learn more about FAir Data principles: https://bit.ly/2ETws2O) No privacy policy, elegant user experience We were conditioned to believe that privacy is the price to pay for convenience. Fairdrop shatters that belief by seamlessly fusing the two. It comes without a privacy policy, because it simply doesn’t collect any data, and at the same time provides a smooth, easy-to-use service. If we want to leave the world of cynical privacy policies behind, then user-friendly zero-data apps are the right path. Decentralized, running on Swarm and Ethereum Fairdrop runs on the Ethereum network and Swarm’s decentralized storage system. This makes it: - fault tolerant, - censorship-resistant, - DDOS-resistant - and with zero downtime. (Learn more about Swarm: https://swarm-gateways.net/bzz:/theswarm.eth/) At the same time it comes with a built-in 256-bit ECDSA encryption algorithm and the ability to send files of up to 5 MB in size. It also comes with four key functionalities. Quick send feature For those that wish to use Fairdrop with minimal hassle and only want to send or share an unencrypted file, this is the easiest feature. Just drag & drop a file, wait until it uploads to Swarm, copy the share link and send it to whoever you want to share it with. A word of warning, anyone with the link will be able to see the content. It literally takes longer to read this paragraph than to fairdrop a file. Secure send feature If you would like the secure sending and sharing possibility, choose this option. Create a password-protected mailbox, choose the recipient, upload a file, encrypt and send it. With this option the encrypted file is safely and privately sent but only to other Fairdrop mailboxes, so make sure your recipient has one. Store feature This option uploads and stores the file to Swarm. You can save it for yourself or share it with others. This is one of the crucial features for future personal data storage applications which will form the basis for an autonomous digital existence. All your data in a private, decentralized and secure storage. Think of it as the beginning of your future digital safe-zone for private & personal data. Take your mailbox with you with the export & import feature The export & import feature promises some of the most interesting capabilities in the future. If you clean your cookies often or want to take your files safely to another computer, just export the mailbox and then import it whenever and wherever you need it. More functionalities are coming We would like to point out that Fairdrop is still in an alpha development stage. This means that we will continue to hone and develop it. Some really neat upgrades are planned in collaboration with the Swarm team, but in general our plans for the next development stage will focus on: - Javascript library so devs can build their own dapps, - the ability to send very large files, - improving the UX, - security review and improvements, - new features. Fairdrop is free to use and open source so give it a spin, take a look at the code, use it and let us know what you think. Or participate in our bug bounty. Talk to us! We don’t have to give up our privacy and freedom just to use an app!
