Bitcoin Q&A: Passphrases and seed storage
 
14:14
Do passphrases protect against leaks or compromises of mnemonic seed words? Why are brain wallets usually insecure? Why should you not "roll your own crypto" and promote creative schemes that deviate from the standards (like BIP39), without at least getting peer review and testing from other developers, cryptographers, or security researchers? See the documentation and support pages of various hardware wallets for more information: Trezor - https://doc.satoshilabs.com/trezor-faq/overview.html https://blog.trezor.io/using-advanced-recovery-on-trezor-4af0eb53c3bb Ledger Nano S - https://support.ledgerwallet.com/hc/en-us/articles/360000613793-Initialize-your-device Ledger Blue - https://support.ledgerwallet.com/hc/en-us/articles/360005835414-Initialize-your-device KeepKey - https://help.keepkey.com/start-here/initialize-your-keepkey https://help.keepkey.com/how-to-guides/how-to-recover-your-keepkey On the topic of inheritance and estate planning, see: https://youtu.be/4g8rO_queMw These questions are from the August monthly Patreon Q&A session, which took place (late) on September 1st 2018.

Bitcoin Q&A: What is difficulty targeting?
 
14:45
How does difficulty targeting work? What determines the desired pattern? Should difficulty re-targeting still happen every 2016 blocks? Could difficulty changes (and hence profitability changes) make all miners drop out? These questions are from the MOOC 7.2 and 9.2 sessions, which took place on February 26th 2017 and February 23rd 2018 respectively. Andreas is a teaching fellow with the University of Nicosia. The first course in their Master of Science in Digital Currency degree, DFIN-511: Introduction to Digital Currencies, is offered for free as an open enrollment MOOC course to anyone interested in learning about the fundamental principles.

Bitcoin Q&A: Privacy, inflation risks, and censorship resistance
 
26:48
How do zero knowledge proofs work? How do you create a zero knowledge proof transaction? Are they computationally difficult? Are privacy coins useful in authoritarian environments? Will MimbleWimble displace Zcash? What implications does the Zcash inflation vulnerability have for privacy in Bitcoin? What problem could banks or international governments pose for Bitcoin without privacy and fungibility? These question are from the February monthly subscriber session, the sixth session of MOOC 11, and the Seoul Bitcoin meetup, which took place on February 23rd, March 7th, and April 5th 2019 respectively.

The Blockchain & Bitcoin - Computerphile
 
17:46
Blockchain is the underlying technology behind cryptocurrencies bringing together Merkle trees, Hashing & Distributed Architecture. Christopher Ellis explains. Note1 - At 6:46 when Chris is drawing the Merkle Tree, C would actually be duplicated and hashed with itself not with B. So you would get H(C - C) instead of H(B - C). Note2 - At minute 17, Christopher mentioned the mining reward halving at 21,000 bitcoins but meant 210,000 blocks.

IOHK | Dr. Peter Gaži, presenting Ouroboros at MIT.
 
01:05:42
Developing a secure proof of stake algorithm is one of the big challenges in cryptocurrency. The Ouroboros protocol has the distinction of being the first proof of stake algorithm that is provably secure and has been peer reviewed at a leading cryptography conference, Crypto 2017. This is essential for a protocol that is to be the foundation of a cryptocurrency, an infrastructure that must be relied on to carry billions of dollars worth of value. In addition to security, if blockchains are going to become infrastructure for new financial systems they must be able to comfortably handle millions of users. The key to scaling up is proof of stake, a far more energy efficient and cost effective algorithm, and as such this research represents a significant step forward in cryptography. Ouroboros is the only provably secure, peer reviewed proof of stake protocol to be implemented – the protocol is an integral part of Cardano, a blockchain system launched in September 2017 and undergoing further extensive development. https://iohk.io/research/papers/#XJ6MHFXX Peter Gaži did his master studies in Computer Science at Comenius University in Bratislava, and obtained his PhD. in Cryptography from ETH Zurich under the supervision of Prof. Ueli Maurer. Later he worked as a postdoc in the Cryptography research group of Prof. Krzysztof Pietrzak at Institute of Science and Technology Austria. Currently, he is a full-time research fellow at IOHK. Peter’s research interests include problems related to security analysis of symmetric cryptography constructions, hash functions and memory-hard functions. His work at IOHK is mostly focused on cryptocurrencies and blockchains. https://iohk.io/team/peter-gazi/ -- Input Output See more at: https://iohk.io Get our latest news updates: https://iohk.io/blog/ Meet the team: https://iohk.io/team/ Learn about our projects: https://iohk.io/projects/cardano/ Read our papers: http://iohk.link/paper-ouroboros Visit our library: https://iohk.io/research/library/ In the press: https://iohk.io/press/ Work with us: https://iohk.io/careers/ See more on Cardano: https://iohk.io/projects/cardano/

Developer Friendly Cryptography | Brice Williams | Hackers of CypherCon
 
46:34
(S1: E5) Software developers often make mistakes when using cryptography in applications, which tends to result in code with dangerous and subtle weaknesses. Some of this can be addressed through training, but should we expect all developers to be cryptography experts? Many developers only know to avoid writing their own ciphers, and rely on one of the many incomplete or incorrect code examples that exist on the internet. To make things worse, most cryptographic libraries in use today are designed to be used by experts and often result in misunderstandings by the average application developer. In this talk we will look at some common cryptography usage errors and why popular libraries often fall short. We will also discuss nuances such as backwards compatibility, FIPS 140-2 validation, and weak standards such as JOSE/JWT that contribute to the overall confusion. Brice will share some advice that you can provide to the development/engineering teams in your organization to not only make their job easier, but also ensure more secure cryptographic implementations.

Bitcoin, What is bitcoin, How to bitcoin  bitcoin cash kurs,  bitconnect

Bitcoin, What is bitcoin, How to bitcoin bitcoin cash kurs, bitconnect Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. Bitcoin cash is a currency unit designed to speed up bitcoin payment transactions. Anybody who owns Bitcoin also has bitcoin cash. To pay faster with Bitcoin you can use the bitcoin currency. This decision is entirely up to you. Let's not forget, the Bcash term is not considered a proper naming. The network is peer-to-peer and transactions take place between users directly through the use of cryptography, without an intermediary These transactions are verified by network nodes and recorded in an immutable public distributed ledger called a blockchain. Bitcoin was invented by an unknown person or group of people under the name Satoshi Nakamoto and released as open-source software in 2009 Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies,[12] products, and services. Mining is a record-keeping service done through the use of computer processing power.[d] Miners keep the blockchain consistent, complete, and unalterable by repeatedly verifying and collecting newly broadcast transactions into a new group of transactions called a block.[46] Each block contains a cryptographic hash of the previous block,[46] using the SHA-256 hashing algorithm,[3]:ch. 7 which links it to the previous block,[46] thus giving the blockchain its name. Miners may aggregate mining resources in a mining pool. To be accepted by the rest of the network, a new block must contain a so-called proof-of-work.[46] The proof-of-work requires miners to find a number called a nonce, such that when the block content is hashed along with the nonce, the result is numerically smaller than the network's difficulty target.[3]:ch. Every 2,016 blocks (approximately 14 days at roughly 10 min per block), the difficulty target is adjusted based on the network's recent performance, with the aim of keeping the average time between new blocks at ten minutes. In this way the system automatically adapts to the total amount of mining power on the network.[3]:ch. 8 Between 1 March 2014 and 1 March 2015, the average number of nonces miners had to try before creating a new block increased from 16.4 quintillion to 200.5 quintillion.[54] Bitcoin has been labelled a speculative bubble by many including former Fed Chairman Alan Greenspan[155] and economist John Quiggin.[156] Nobel Memorial Prize laureate Robert Shiller said that bitcoin "exhibited many of the characteristics of a speculative bubble".[157] Journalist Matthew Boesler in 2013 rejected the speculative bubble label and saw bitcoin's quick rise in price as nothing more than normal economic forces at work.[158] Timothy B. Lee, in a 2013 piece for The Washington Post pointed out that the observed cycles of appreciation and depreciation don't correspond to the definition of speculative bubble.[133] On 14 March 2014, the American business magnate Warren Buffett said, "Stay away from it. It's a mirage, basically."[159] The price of bitcoins has gone through various cycles of appreciation and depreciation referred to by some as bubbles and busts.[131][132] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[133] In the latter half of 2012 and during the 2012–13 Cypriot financial crisis, the bitcoin price began to rise,[134] reaching a high of US$266 on 10 April 2013, before crashing to around US$50.[135] On 29 November 2013, the cost of one bitcoin rose to a peak of US$1,242.[136] In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. As of August 2014 it was under US$600.[137] According to Mark T. Williams, as of 2014, bitcoin has volatility seven times greater than gold, eight times greater than the S&P 500, and 18 times greater than the US dollar.[138] According to Forbes, there are uses where volatility does not matter, such as online gambling, tipping, and international remittances.[139] In January 2015, noting that the bitcoin price had dropped to its lowest level since spring 2013 – around US$224 – The New York Times suggested that "[w]ith no signs of a rally in the offing, the industry is bracing for the effects of a prolonged decline in prices. bitcoin,bitcoin cash kurs,bitcoin mining,bitcoin price,bitcoin usd,buy bitcoin,what is bitcoin,how to buy bitcoin cash,que es el bitcoin,bitcoin diamond,bitcoin gold wallet,how to mine bitcoin at home,cboe bitcoin,buys bitcoin once,bitzeny,bitcoin blase,le bitcoin,how to bitcoin,bitcoin explained,bitcoin in hindi,cryptocurrency,blockchain,cryptocurrencies,bitcoin millionaire,Cryptocurrency Mining,virtual currency

Proof of Stake vs Poof of Work Introduction - Vitalik Buterin
 
26:50
Vitalik Buterin’s “Mauve Revolution” presentation, is the culmination of months of in-depth research and development work. His presentation was well received, and it was reassuring to know that the preparations for proof-of-stake (PoS) are at an advanced stage. The transition from proof-of-work (PoW) to proof-of-stake (PoS) is important work, not without risk, and crucial to get right. Thankfully, Vitalik Buterin and his highly capable team are in charge of this pioneering work, and there is no reason why the implementation won’t succeed in achieving its design goals. The Ethereum Foundation has a great track record of meeting software development goals and responding correctly and quickly under pressure. Therefore, they will take their time releasing Casper and hold off if necessary. But once done, it will be a significant advancement for Ethereum and the blockchain ecosystem. 🙏Thank you so much for spending your time to watch this video and please don't forget to LIKE & SUBSCRIBE.

DEF CON 24 - Marc Newlin - MouseJack: Injecting Keystrokes into Wireless Mice
 
42:35
What if your wireless mouse was an effective attack vector? Research reveals this to be the case for mice from Logitech, Microsoft, Dell, Lenovo, Hewlett-Packard, Gigabyte, and Amazon. Dubbed 'MouseJack', this class of security vulnerabilities allows keystroke injection into non-Bluetooth wireless mice. Imagine you are catching up on some work at the airport, and you reach into your laptop bag to pull out your phone charger. As you glance back at your screen, you see the tail end of an ASCII art progress bar followed by your shell history getting cleared. Before you realize what has happened, an attacker has already installed malware on your laptop. Or maybe they just exfiltrated a git repository and your SSH keys. In the time it took you to plug in your phone, you got MouseJacked. The attacker is camped out at the other end of the terminal, equipped with a commodity USB radio dongle and a directional patch antenna hidden in a backpack, and boards her plane as soon as the deed is done. The reality of MouseJack is that an attacker can inject keystrokes into your wireless mouse dongle from over 200 meters away, at a rate of up to 7500 keystrokes per minute (one every 8ms). Most wireless keyboards encrypt the data going between the keyboard and computer in order to deter sniffing, but wireless mouse traffic is generally unencrypted. The result is that wireless mice and keyboards ship with USB dongles that can support both encrypted and unencrypted RF packets. A series of implementation flaws makes it possible for an attacker to inject keystrokes directly into a victim's USB dongle using easily accessible, cheap hardware, in most cases only requiring that the user has a wireless mouse. The majority of affected USB dongles are unpatchable, making it likely that vulnerable computers will be common in the wild for the foreseeable future. This talk will explain the research process that lead to the discovery of these vulnerabilities, covering specific tools and techniques. Results of the research will be detailed, including protocol behavior, packet formats, and technical specifics of each vulnerability. Additional vulnerabilities affecting 14 vendors are currently in disclosure, and will be revealed during this talk. Marc is a security researcher and software engineer at Bastille Networks, where he focuses on RF/IoT threats present in enterprise environments. He has been hacking on software defined radios since 2013, when he competed as a finalist in the DARPA Spectrum Challenge. In 2011, he wrote software to reassemble shredded documents for the DARPA Shredder Challenge, finishing the competition in third place out of 9000 teams. Twitter: @marcnewlin
