Is blockchain + AI a winning combo? Yes! They are complementary technologies, and knowing how both work will make you a much more powerful developer. Artificial Intelligence can use the power of the blockchain to audit data, add incentives to its goals, and even create new types of meritocratic organizations. In this video, i'll talk about how they can both work together, code out the proof of work algorithm in python, then talk about a few other consensus algorithms at a high level.

One of the challenges for patients with rare diseases is the lack of local data to use for analysis. As a result, patients are having to rely on 3rd party facilities to carry out the computations based on data collected around the globe. But due to patient privacy concerns, as well as heavy legal and regulatory barriers, these facilities are often prevented from sharing vital data which could help save lives.
Join David Wu as he discusses how modern cryptographic tools can be leveraged for genome privacy.

Generating random numbers on computers is not easy. And while the intended solution was really hard, the challenge had a problem with the random number generation, which allowed me to solve it.
Clarification from Andres Moreno (riscure) on the challenge:
"The "official" challenge solution involved reading the tiny Mersenne twister (tinyMT) paper, writing some equations, and using a solver. The tinyMT is tricky to initialize. Giving a proper seed is not enough. You need to provide initial state matrices with certain properties (there is a generator for this). The challenge used improper initialized matrices (zeros) that reduced the PRNG period. During tests, we found that ~12hr were needed to solve the challenge (solver time only), but we did not test the amount of entropy reduction by improper state initialization. Fortunately, the problem was not in the PRNG."

Why learn Blockchain?
Blockchain is a revolutionary technology. It is an ordered back linked-list data structure of blocks of transactions stored in a decentralized peer- to-peer network. It is the underlying infrastructure for bitcoin, a popular cryptocurrency. In near future, many companies will be adopting blockchain technologies for trading publicly. Apart from bitcoin, it can be used for a wide variety of applications such as tracking ownership, digital assets, physical assets, or voting rights. It can also store and run computer code called ‘smart contracts’. However, blockchain is still new and the communities are still exploring the best ways in which it can be used.

In this video, we answer one of the most asked questions we get: Robert and I list the 10 key differences between Ethereum and DFINITY. Some of the key differences stem from DFINITY's new consensus protocol and we list those. But we start with differences on other layers. Dive in to hear all ten key differences between Ethereum and DFINITY!
10 Differences Between DFINITY and Ethereum:
[0:37] 1. Internet Computer vs. Smart Contract Platform
[1:11] 2. On-Chain Governance vs. Off-Chain Governance
[1:50] 3. Actor Model vs. Serialized Contract Execution
[2:14] 4. WebAssembly (WASM) vs. Domain-Specific Languages
[3:18] 5. Proof of Stake vs. Proof of Work
[4:29] 6. Fixed-Sized Deposits vs. Variably-Sized Deposits
[5:09] 7. Security over Liveness vs. Liveness over Security
[6:36] 8. Random Beacon vs. Proof of Work
[8:23] 9. Cryptographic Finality vs. Economic Finality
[10:10] 10. Finality Time: 2 Blocks vs. 125 Blocks
About Cédric:
Cédric Waldburger joined DFINITY early on and is now focusing on the Growth. He leads the initiatives on Developer and Mining adoption, alongside with heading some of DFINITY's partnerships. Prior to joining DFINITY, he's been a founder and investor and has been a crypto enthusiast since 2012. He has been passionate about startups. Having founded his first company at the age of 14, he has built various tech companies related to productivity, computer vision, and cryptocurrencies. In this immensely exciting and obliging journey, he instigates the avenues of bringing the maximum impact wherever he can and is skilled to. For accomplishing this journey and his drive, he hasn't owned an apartment in several years. Instead, he has since lived out of a bag with only 64 things.
About DFINITY:
The DFINITY project was formed to research ways of enabling public decentralized networks to host a virtual computer of unlimited capacity. This rests upon a new blockchain computer that is similar in concept to Ethereum but has vastly improved performance and, ultimately, unlimited capacity.

Portable Document Format (PDF) is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, graphics, and other information needed to display it. In 1991, Adobe Systems co-founder John Warnock outlined a system called "Camelot" that evolved into PDF.
While Adobe Systems made the PDF specification available free of charge in 1993, PDF was a proprietary format, controlled by Adobe, until it was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008, at which time control of the specification passed to an ISO Committee of volunteer industry experts. In 2008, Adobe published a Public Patent License to ISO 32000-1 granting royalty-free rights for all patents owned by Adobe that are necessary to make, use, sell and distribute PDF compliant implementations. However, there are still some technologies referenced by ISO 32000-1 that can be incorporated into valid PDF files that remain proprietary (but still publicly documented), such as Adobe XML Forms Architecture, and JavaScript for Acrobat. The ISO committee is actively standardizing many of these as part of ISO 32000-2.

SUMMARY
=======
Science and technology in Venezuela includes research based on exploring Venezuela's diverse ecology and the lives of its indigenous peoples.
Under the Spanish rule, the monarchy made very little effort to promote education in the American colonies and in particular in those in which they had less commercial interest, as in Venezuela. The country only had its first university some two hundred years later than Mexico, Colombia or Peru.
The first studies on the native languages of Venezuela and the indigenous customs were made in the middle of the XVIII century by the Catholic missionaries. The Italian Jesuit Filippo Salvatore Gilii was one of the first to theorize about linguistic relations and propose possible language families for the Orinoco river basin. The Swedish botanist Pehr Löfling, one of the 12 Apostles of Carl Linnaeus, classificated for the first time the exhuberant tropical flora of the Orinoco river basin.
In the XIX century several scientists visited Venezuela such as Alexander Humboldt, Aimé Bonpland, Agostino Codazzi, Jean-Baptiste Boussingault, Mariano Rivero, François de Pons, Robert Hermann Schomburgk, Wilhelm Sievers, Carl Ferdinand Appun, Gustav Karsten, Adolf Ernst, Benedikt Roezl, Karl Moritz, Friedrich Gerstäcker, Anton Goering, Johann Gottlieb Benjamin Siegert, Alfred Russel Wallace, Jean Chaffanjon, Émile-Arthur Thouar, Jules Crevaux and many others, some of whom are buried in Venezuela.
The Venezuelan Institute for Scientific Research (IVIC) founded on February 9, 1959 by government decree, has its origins in the Venezuelan Institute of Neurology and Brain Research (IVNIC) which Dr. Humberto Fernandez Moran founded in 1955.
Other major research institutions include the Central University of Venezuela and the University of the Andes, Venezuela.
Notable Venezuelan scientists include nineteenth century physician José María Vargas , the chemist Vicente Marcano and the botanist and geographer Alfredo Jahn (1867–1940). More recently, Baruj Benacerraf shared the 1980 Nobel Prize in Physiology or Medicine, Augusto Pi Sunyer (1955), Aristides Bastidas (1980), Marcel Roche (1987) and Marisela Salvatierra (2002) have been recipients of UNESCO's Kalinga Prize for promotion of the public understanding of science. On July 2, 2012, L. Rafael Reif – a Venezuelan American electrical engineer, inventor and academic administrator – was elected president of the Massachusetts Institute of Technology.
