What is the Blockchain?
blockchain, NOUN /ˈblɒktʃeɪn/
A digital ledger in which transactions made in bitcoin or another cryptocurrency are recorded chronologically and publicly.

A mysterious white paper (Nakamoto, Satoshi, 2008, “Bitcoin: A Peer-to-Peer Electronic Cash System”) introduced the Bitcoin blockchain, a combination of existing technologies that ensures the integrity of data without a trusted party. It consists of a ledger that can’t be changed and a consensus algorithm—a way for groups to agree. Unlike existing databases in banks and other institutions, a network of users updates and supports the blockchain—a system somewhat similar to Wikipedia, which users around the globe maintain and double-check. The cryptocurrency Bitcoin is the first use case of the blockchain, but much more seems to be possible.
The Next Generation of the Internet

The first 40 years of the Internet brought e-mail, social media, mobile applications, online shopping, Big Data, Open Data, cloud computing, and the Internet of Things. Information technology is at the heart of everything today—good and bad. Despite advances in privacy, security, and inclusion, one thing is still missing from the Internet: Trust. Enter the blockchain

The Blockchain and Us: The Project

When the Wright brothers invented the airplane in 1903, it was hard to imagine there would be over 500,000 people traveling in the air at any point in time today. In 2008, Satoshi Nakamoto invented Bitcoin and the blockchain. For the first time in history, his invention made it possible to send money around the globe without banks, governments or any other intermediaries. Satoshi is a mystery character, and just like the Wright brothers, he solved an unsolvable problem. The concept of the blockchain isn’t very intuitive. But still, many people believe it is a game changer. Despite its mysterious beginnings, the blockchain might be the airplane of our time.

Economist and filmmaker Manuel Stagars portrays this exciting technology in interviews with software developers, cryptologists, researchers, entrepreneurs, consultants, VCs, authors, politicians, and futurists from the United States, Canada, Switzerland, the UK, and Australia.

How can the blockchain benefit the economies of nations? How will it change society? What does this mean for each of us? The Blockchain and Us is no explainer video of the technology. It gives a view on the topic, makes it accessible and starts a conversation about its potential wider implications in a non-technical way. The film deliberately poses more questions than it answers. For a deep dive, see all full-length interviews from the film here. Additional information about the project is in the Q&A and Disclaimer.

A beginner's guide to Ethereum. #Infographic @jaxx_io


A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network. The network timestamps transactions by hashing them into an ongoing chain of hash-based proof-of-work, forming a record that cannot be changed without redoing the proof-of-work. The longest chain not only serves as proof of the sequence of events witnessed, but proof that it came from the largest pool of CPU power. As long as a majority of CPU power is controlled by nodes that are not cooperating to attack the network, they'll generate the longest chain and outpace attackers. The network itself requires minimal structure. Messages are broadcast on a best effort basis, and nodes can leave and rejoin the network at will, accepting the longest proof-of-work chain as proof of what happened while they were gone.

Predictions 2017: Pioneering Financial Providers Will Partner With Fintech To Build Ecosystems. Forrester Research

Hoy traemos a este espacio el informe de Forrester titulado "Predictions 2017: Pioneering Financial Providers Will Partner With Fintech To Build Ecosystems" y en el que nos explican por qué leerlo así:

Why Read This Report 

A gap is emerging between the financial firms that are embracing digital business transformation and those that continue doing things the same old way. In 2017, this gap will widen significantly as leading providers experiment with new ways to win, serve, and retain customers. This report lays out Forrester’s predictions for how financial services will change in 2017, driven by new regulations, evolving customer behavior, and new techniques for engaging customers and prospects.(leer más...)

The rise of human-computer cooperation. El auge de la cooperación entre seres humanos y computadoras. Shyam Sankar

Hoy traemos a este espacio esta charla TEDx de Julio de 2012 titulada "El auge de la cooperación entre seres humanos y computadoras." de Shyam Sankar

Brute computing force alone can't solve the world's problems. Data mining innovator Shyam Sankar explains why solving big problems (like catching terrorists or identifying huge hidden trends) is not a question of finding the right algorithm, but rather the right symbiotic relationship between computation and human creativity.
This talk was presented at an official TED conference, and was featured by our editors on the home page.

Shyam Sankar · Data Intelligence Agent
An advocate of human-computer symbiosis, Shyam Sankar looks for clues in big and disparate data sets.

Why you should listen

Shyam Sankar is a Director at Palantir Technologies, a secretive Silicon Valley company where he oversees deployments of the company's core technology, which helps law enforcement teams and corporations analyze giant, unrelated databases for clues to potential ... anything. Palantir technologies has been used to find missing children, to detect banking fraud, and to uncover the Shadow Network, a cyber-spy ring that stooped so low as to hack the Dalai Lama's email.
As part of his work, Sankar thinks deeply about the place where human and machine intelligence meet. While artificial intelligence (AI) is the dominant paradigm, he is an advocate of JCR Licklider's "intelligence augmentation" (IA) approach, where algorithms and brains work together to solve problems.

What others say

“Palantir's software pulls off one of the great computer science feats of the era: It combs through all available databases, identifying related pieces of information, and puts everything together in one place.” — Bloomberg Businessweek (leer más...)
