Bitcoin and its users employ a variety of obfuscation techniques to increase their financial privacy. We visualize a representative selection of these techniques in Figure 1 based on their time of invention/creation and our assessment of their similarity to obfuscation vs. cryptography. We make several observations. First, techniques used in Bitcoin predominantly fall into obfuscation, with stronger techniques being used exclusively in alternative cryptocurrencies (altcoins). Second, there is a trend towards stronger techniques over time, perhaps due to a growing interest in privacy and to the greater difficulty of developing cryptographic techniques. Third, obfuscation techniques proposed at later points in time are seeing less adoption, arguably a result of their increased complexity and need for coordination among participants (Möser & Böhme 2017).
HSBC aims to shift $20 billion worth of assets to a new blockchain-based custody platform by March, in one of the biggest deployments yet of the widely-hyped but still unproven technology by a global bank.
The platform, known as Digital Vault, will give investors real-time access to records of securities bought on private markets, HSBC (HSBA.L) told Reuters, and seeks to capitalize on booming interest in such investments by yield-hungry investors.
2019 CIGI-Ipsos Global Survey Highlights 1. Social media companies were second only to cyber criminals when it came to fueling online distrust.75% say social media companies are responsible for their online distrust In the 2019 survey, social media companies emerged as the leading source of user distrust in the internet — surpassed only by cybercriminals — with 75% of those surveyed citing Facebook, Twitter and other social media platforms as contributing to their lack of trust. People from Canada and Great Britain, at 89%, were the most likely to point to social media as a source of their distrust, followed by Nigeria (88%), the United States (87%) and Australia (83%). People from Japan (49%), Tunisia (60%), Hong Kong (63%) and Korea (64%) were the least likely to do so. Almost nine in ten (88%) North Americans who distrust the Internet cited social media as responsible for their distrust, the highest proportion out of all regions surveyed. While cybercriminals, cited by 81%, remained the leading source of internet distrust, a majority in all regions (62% globally) indicated that a lack of internet security was also a significant factor — up significantly from 48% in 2018. 2. More than half of those concerned about their online privacy say they’re more concerned than they were a year ago.53% are more concerned about their online privacy than they were a year ago Eight out of 10 (78%) people surveyed were concerned about their online privacy, with over half (53%) more concerned than they were a year ago, marking the fifth year in a row that a majority of those surveyed say they feel more concerned about their online privacy than the previous year. Fewer than half (48%) believe their government does enough to safeguard their online data and personal information, with the lowest confidence levels in North America (38%) and the G-8 countries (39%). Citizens around the world are increasingly viewing their own governments as a threat to their privacy online. In fact, more people attributed their online privacy concerns to domestic governments (66%) — a majority in nearly every region surveyed — than to foreign governments (61%). While 73% said they wanted their online data and personal information to be stored in their own country, majorities in Hong Kong (62%), Indonesia (58%), Egypt (58%), India (57%), Brazil (54%), and Mexico (51%) said they wanted their online data and personal information stored outside of their country. In contrast, only 23% of North Americans, 35% of Europeans and 32% of those in G-8 countries shared this sentiment. 3. A majority admit to falling for fake news at least once — citing Facebook as the leading source — and want both governments and social media companies to take action.86% have fallen for fake news at least once 86% said they had fallen for fake news at least once, with 44% saying they sometimes or frequently did. Only 14% said they had “never” been duped by fake news. Facebook was the most commonly cited source of fake news, with 77% of Facebook users saying they had personally seen fake news there, followed by 62% of Twitter users and 74% of social media users in general. 10% of Twitter users said they had closed their Twitter account in the past year as a direct result of fake news, while 9% of Facebook users reported doing the same. One-third (35%) pointed to the United States as the country most responsible for the disruptive effect of fake news in their country, trailed significantly by Russia (12%) and China (9%). Notably, internet users in Canada (59%), Turkey (59%) and the United States itself (57%) were most likely to say that the United States is most responsible for the disruptive effect of fake news in their own country, while users in Great Britain (40%) and Poland (35%) were most likely to point to Russia, and users in Hong Kong (39%), Japan (38%) and India (29%) were most likely to blame China. A majority of internet users around the globe support all efforts that governments and internet companies could take to combat fake news, from social media and video sharing platforms deleting fake news posts and videos (85%) and accounts (84%) to the adoption of automated approaches to content removal (79%) and government censorship of online content (61%). 4. Distrust in the internet is causing people to change the way they behave online.49% say their distrust has led them to disclose less personal information online Nearly half (49%) of those surveyed said their distrust had caused them to disclose less personal information online, while 43% reported taking greater care to secure their devices and 39% said they were using the internet more selectively, among other precautions. Conversely, only a small percentage of people reported making use of more sophisticated tools — such as using more encryption (19%) or using technical tools like Tor (The Onion Router) or virtual private networks (VPNs) — to protect themselves online. 5
In sum, the blockchain back end shouldn’t matter to users – just like the Internet’s DNS or TCP/IP protocols don’t matter to web users. All web users care about is their web-based applications. All Blockchain users need to care about is their decentralized applications.Make no mistake: The days of seamless blockchain interoperability at the ‘atomic’ level are not here yet. Nor are the days of cross chain functionality where a single smart contract can update multiple blockchain platforms using a single process. We won’t see these needed functions go mainstream for at least two years.But the good news is we are seeing some very promising developments that will help move us closer to this end state, as highlighted in our recently published Hype Cycle for Blockchain Technology 2019.source: Hype Cycle for Blockchain Technology, 2019
ARTICLE 19 has issued a warning about the promotion of blockchain technology as a solution to censorship. In a report published today, the freedom of expression organisation identifies some of the risks that arise from the use of blockchain technology. It also identifies steps that states, public organisations and tech companies should take to ensure that human rights are protected when this technology is used.

This article presents the top ten obstacles towards the adoption of distributed ledgers, ranging from identifying the right ledger to use for the right use case to developing scalable consensus protocols that provide some meaningful notion of public verifiability.
What is a DAO? Here, we take as an (imperfect) definition something simple: “a censorship-resistant means to coordinate the deployment of shared resources towards a shared objective”. The simplest DAO, by this definition, would be a multi-sig wallet, in which individual members can withdraw paltry sums and many members together can withdraw significant sums.While a multi-sig may be sufficient for a group of friends on a backpacking trip, it quickly becomes apparent that for more ambitious objectives requiring the coordination of more resources, additional mechanisms are necessary. How permeable should the boundaries of the organization be? How much influence should any individual have? How can individuals be protected from the bad behavior of others? How easy or difficult is it to participate?For a certain type of person, these questions are irresistible, and it no surprise that many significant projects have emerged in recent years seeking to answer these questions. People frequently ask about the ways in which these projects are similar and different from each other; this essay is a step towards an answer.This commentary is based on my familiarity with these projects and their technical documentation, much of which I have read, as well as conversations with teammates from the various projects.
